(sorry, I'm on my phone and I must have hit a Presidential limit)

I got a flock of over 250 Sandhill Cranes. Then, in returning to town, I stopped along CR 40 about 5 miles south of town to look for Burrowing Owls- - I found 3 but also had 5 more Mountain Plover!

Subject: [cobirds] east- central CO birding

I always seem to have trouble fixing one spot in my subject line since I'm usually on the move.

I headed out after lunch on the road to Wads. John Vanderpoel suggested keeping on I 70 to Arriba and then trying for Mountain Plover along Lincoln county road 3E. Good idea as I found one plus about 50 longspurs including both McCown's and Chestnut- collared.

in Ears itself, I had a blackbird flock with RWBL, YHBL, COGR, GTGR and BHCO. Then I headed south to the Great Plains Reservoirs.

John Stump and I spent a morning out birding under gray skies. Birding was
good and we had 4 species of gulls: California, RB, Franklin's and
Bonaparte's. Rock and Marsh Wrens were at Smith Reservoir. Best of the day
was a flock of 9 Mountain Plovers south of Smith (Costilla County) in a
bare soil area. This is the largest flock ever recorded here and the second
earliest date for the species in the San Luis Valley. Great day out and
about.

Observation start time: 08:45:00

Total observation time: 5.25 hours

Official Counter: Roger Rouch

Observers:

Visitors:
None.


Weather:
Low clouds obscured Mt. Morrison and the west ridges and mostly cloudy
early, but the clouds quickly lifted turning to a partly cloudy (or partly
sunny) day. A brisk wind of about 3 Bft. from the NE all day.
Temperatures from 40 F to the mid- 50's.

Raptor Observations:
Most migration was straight north flight at the "eye level to 30 meter"
elevation and just east of the ridge, leading one to think ridge lift from
the NE wind and lack of good thermals influenced the flight pattern. A
Bald Eagle was a nice highlight. I will post a photo for comment or
correction, but I believe it was a 4th year sub-adult. A distant raptor
high and beyond the west ridges had Golden Eagle clues but was recorded as
an unidentified raptor. Other than the local Red-tailed pairs there was
little activity over the western ridges.

Non-raptor Observations:
A dozen Western Bluebird landed in the dead pine just SE of the platform.
A few other smaller groups of 1 to 4 flew by and all seemed to have a
northern direction to their flight. Also seen or heard, Black-billed
Magpie, Townsend's Solitaire, Common Raven, American Robin, Woodhouse's
Scrub-jay, Western Meadowlark, Spotted Towhee.

Predictions:
Optimistically, it is near peak season and maybe a little post storm
make-up migration, so a good day?

In spite of last night's rain and snow the trail is just fine.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge - Bird Conservancy of the Rockies information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Hi all

Some may already know this so ignore.

I thought I'd visit Timnath on my lunch break only to find road closed to
park on south. It is closed until 3/31 according to this link:
http://timnath.org/updates/access-timnath-reservoir-closed-320-331/. Also,
for what it is worth, while browsing their town website (FYI here)
according to this URL
(http://timnath.org/wp-content/uploads/2014/03/Timnath-Reservoir-Policy-Only-Update-8-17-2016_MG.pdf)
Timnath Reservoir is:

*INTENT*
The Town leases Timnath Reservoir for the enjoyment of Timnath residents.
The purpose of this policy is to outline the rules for Timnath Reservoir’s
use.

*POLICY*
I. For Timnath Residents – At this time, Timnath Reservoir will
be restricted to the use and enjoyment for Timnath Residents and their
guests.

The NE corner of Timnath has more residential dwelling going up on north
shore, noticed a nice new road going in along north shore as well as what
looks to be a cement hiking path meandering through the marsh up there
towards house where birders typically walk down to shoreline when reservoir
drying up.

I have yet to see enforcement for above ...

Subject: [cobirds] Common Loon and Greater Yellowlegs on Baseline Reservoir today
Hi all -

I stopped by Baseline Reservoir outside of Boulder a couple of times today
while I was running some errands. Right after lunch, about 12:30, I saw
two Greater Yellowlegs working the shallows on the south end. The other
usual suspects were there, a bunch of Hooded Mergansers, some Bufflehead
and Goldeneye and a few Ruddy Duck and Green Winged Teal.. On my way home
this afternoon, around 2:45, I saw a big bird swimming around on the north
end. Pulled out the binoculars, and it was a Common Loon, in breeding
colors. Had to pull out the scope for a really good look, even though it
was not too far out. The white bands on the side of the neck clearly had
vertical black stripes, and the back was a nice checkered pattern, black
over white. Dark brown head, large dark beak. On the way past the west
side, I saw a Horned Grebe and a big flock of Crows - approximately 50 -
working the sandy beaches and perching in the trees.

Good birding -

Subject: [cobirds] NO brant, Arapahoe County
I went down around to all of the ponds this morning and did not find the brant or the flock of geese he was with. I did find a pair of hooded mergansers, a pair of wigeons and Red breasted nuthatches.
There was also a large coyote perusing the north side of the ponds as I went around the south side of the ponds. He was too far away for me to try to haze so I listened and watched the reaction of the birds in the area as he came through. They have a good alarm system and he never had a chance at a meal.
Thanks to everyone who came by to share my yard bird! It was a lot of fun.

Subject: [cobirds] little help on IDs of Eastern waterfowl from bad photos
Hi, folks--
In case anyone has an extra minute or two, I have some poor photos from a recent trip to coastal islands off SC where I was challenged by a number of bird IDs that I have little knowledge of. If anyone is willing to look at two of them, I'd appreciate opinions. I am null at shorebirds and weak on ducks I've never seen before!

I was surprised to discover that the huge flocks of peeps we were seeing were mostly WESTERN Sandpipers. I have much to learn!
Alas, we did not get even poor photos of many mysterious flying creatures. It was fun-- and frustrating.

We tried for the Red-cockaded Woodpecker and frustratingly, heard one but could not find it. The forest was still smoldering from a recent prescribed fire which is used to help manage the forests that they prefer. Nevertheless, it was a good trip for woodpeckers in general: lots of practice.

Cheryl just came from outside saying "I heard a hummingbird!" And then it was at a feeder.

Hi all,

Went down to Picketwire Canyon in the Comanche National Grassland for an
overnight camping trip. Spring arrivals in the canyon include Eastern and
Say's Phoebes, Rock Wren, Turkey Vulture, Killdeer, and White-throated
Swift. It was also nice to spend some time with Bewick's and Canyon Wrens,
Rufous-crowned Sparrow, and Ladder-backed Woodpecker. I was hoping for an
early poorwill or Black-throated Sparrow, but no luck. Winter birds still
in evidence included Dark-eyed Junco and Townsend's Solitaire.

All the ravens I could identify with confidence were Commons, though I did
hear some suspiciously upslurred croaks at Vogel Canyon.

Probably the rarest sighting was an early male *Lark Bunting* that flew
across Highway 71 in Crowley County north of Box Springs yesterday.

Observation start time: 09:30:00
Observation end time: 10:30:00
Total observation time: 1 hours

Official Counter: Gary Rossmiller

Observers:

Visitors:
2 birders, Barrett and Mary Hargreaves, stopped by at the top of the hour,
they had never been up there before. I showed them our cheat sheet from
HMANA.org. They mentioned bird watching along the Platte River in
Littleton. The mentioned seeing a Kestrel perched on the wires on the way
up.


Weather:
Overcast, wind blown moisture. Sun found a hole in the clouds around the
top of the hour for 20 minutes. Wind out of the north at 3-4 bft, a few
higher gusts. Clouds eventually cleared over the ridge to the west but Mt.
Morrison's summit was never seen. Could almost see the horizons. Storm
seemed to be heavier to the north.

Raptor Observations:
Parked on Rooney Road, didn't expect to see the ridge through the clouds.
Got out and immediately saw a local RT near the ridge. Hiked up to the
platform. Closer to 10:30 2 local RT's worked the fields on the east side.
Once back at the parking lot a 3rd RT was visible.
Otherwise no migrating raptors.

Non-raptor Observations:
Over 50 elk on Bare Slope. Small birds fairly active; Canyon Wren heard,
Meadowlark, Magpie, Robin, Scrub Jay, Spotted Towhee disappeared into the
shrubs, and a flock of Mountain Bluebirds at the saddle to the south.

Predictions:
Another wet day but maybe migration?
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

The first broad-tailed of the season fed at one of our feeders at 9:50 this
morning. I thought I heard one fly overhead on March 22 but got no visual
confirmation. I heard this guy first also and was beginning to doubt my ear
as I stood shivering outside for five minutes. Then I saw him at our front
feeder. We have had our feeders out about three weeks. Our previous
earliest date for a broad-tailed was April 5.

For the last couple of days I have a bird at my feeders that matches the
Pacific Northwest ssp of Spotted Towhee. Very few white spots and
extensively dark rufous sides. The song also seems to be different.

Subject: [cobirds] RFI. Rosy-finch and ptarmigan info for visiiting birders
We'll be visiting Colorado next week, primary focus is Gunnison Sage-Grouse
but as time allows I wanted to try for rosy-finches (black and
brown-capped) and white-tailed ptarmigan. So had a couple of questions:

1. I've heard from others that have had some success at Loveland Pass for
ptarmigan this time of year. Is that generally a good spot to try and how
much effort is required to have a decent chance for them? I wasn't planning
on packing snowshoes or other winter hiking gear on our trip.
2. Recommended spots for rosy-finches in early April? I'm guessing they are
starting to disperse. Checking eBird reports, but any tips on reliable
spots for rosy-finch flocks that would be likely in first week of April are
appreciated.

Thanks in advance for the help.

Observation start time: 08:00:00
Observation end time: 14:00:00
Total observation time: 6 hours

Official Counter: Joyce Commercon

Observers: Jim Schmoker

Visitors:
Brian Johnson arrived early in the morning with binoculars, hoping to see
some migrating raptors before heading off to look for nesting peregrines.
Pam Batton and Trey Corkern also came armed with binoculars later in the
morning, ready to help with the watch for a while. Jim Schmoker’s help in
spotting and tracking birds for several hours today was also greatly
appreciated.
Jefferson County Schools are apparently on break this week, so there were
many more families and groups with children on the trail today, along with
the usual hikers and bikers. Most came up for view only. However, one pair
did show some interest in what was being seen; luckily at that moment,
there was a local, adult Red-tailed Hawk that was hunting nearby in Rooney
Valley. This provided them with a perfect example of the main migrant of
the day.


Weather:
The watch began with blue sky and sun (with cloud-cover at 5-10 percent)
but shifted to partly cloudy, then mostly cloudy (cloud-cover at about 80
percent) as a gray mass moved in from the northwest near noon MST. It was
mildly breezy (bft 2 and 3) with winds initially from the north shifting to
come generally from the east by mid-morning. Temperatures ranged from 8 C
to 17 C. A thin, white foggy haze was observed to move northward from the
Chatfield Lake area into the valley southeast of the Ridge in the morning.
An orange-brown haze hung low and heavy in the morning in the Denver Basin
to the northeast. Visibility was generally good, if a bit more hazy than
usual.

Raptor Observations:
Two Sharp-shinned Hawks pushed north together low and close to the Ridge in
the early morning, but nearly all the migrants today were Red-tailed Hawks
that passed on the west side of the Ridge. Many migrated over the far
western ridges from Mount Morrison to Cabrini/Bare Slope. Height-of-flight
for the Red-tailed Hawks was high (HF2) and higher (HF3). Local Red-tailed
Hawks were observed often today. A pair near West Ridge was seen chasing
and diving after some Common Ravens in the morning. Possibly the same pair
was seen circling with dropped legs near West Ridge again during the noon
MST hour; one of the pair performed a steep, sharp roller-coaster flight.
The absolute highlight of the day came right at the end of the watch when
five local Red-tailed Hawks circled high together but at differing heights
over the west-side valley; the uppermost pair fell from the sky
together—spinning, cartwheeling with talons clasped—then releasing and
parting after a few seconds. A sixth local adult Red-tailed Hawk (recently
observed hunting at the base of Green Mountain) joined the other five in
the west-side valley. The grouping dispersed with some heading west and
some heading south.

Non-raptor Observations:
A Canyon Wren was heard very clearly again today. A Raven, that croaked
with a higher pitch than one might expect, landed briefly on one of the
power poles to the north of the HawkWatch platform. Also seen or heard were
Western Meadowlark, Woodhouse’s Scrub-Jay, Townsend’s Solitaire,
Black-billed Magpie, American Robin, American Crow, Spotted Towhee and
Northern Flicker.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

I currently have a brant at my house outside of Littleton. He's in the pond of course, not actually at my house.

I will be home for a while if anyone wants to run over to see it. My phone number is
303-408-3010. Please call if heading over. I live 1/2 mile south of Bowles off Platte Canyon Drive. I can give you further directions if needed. He appears to be with a Richardsons white cheeked goose as far as I can tell.

Subject: [cobirds] Tundra Swan [Stewart's Pond, Lasalle, Weld]
Hi all

I found the Tundra Swan but not the Eurasian Wigeon :-( ... couple others
there looking as well. Other spring arrivals:

- Say's Phoebe [Yard, Nunn, Weld]
- Common Grackle [Windsor Lake, Windsor, Weld]
- Red-breasted Merganser [Windsor Lake, Windsor, Weld]
- American Avocet [Three ponds across from Behren's Lake, Lasalle, Weld]

There were ~400+ American White Pelican(!) at Neff Lake. At Glenmere Park
I had a immature Red-tailed Hawk no more than 10 feet from me at eye level
on a fence post. It had picked up a strip of brown cloth and either (1)
thought it was a snake or (2) was trying to make thinner strips for
nesting. It is by far the CLOSEST I've gotten to a hawk in the wild,
pretty neat--it did not care about my presence at all.


Thanks Gary Lefko, Nunn

Subject: [cobirds] Larimer County Gulls (Great Black-backed Gull)
I visited the local gull hotspot this evening (5:45-7 pm) and was not disappointed, as 800 gulls lounged on the mudflats and shallow waters of Horseshoe Lake's southwest corner, located in northeast Loveland, just west of Boyd Lake State Park.

Most (95%) of these gulls are staging adult California Gulls which will eventually move out to a nearby nesting colony, either in Jackson or Weld County. Today, there were about 35 (4%) Herring Gulls, many in adult breeding plumage. There were 8 (1%) Lesser Black-backed Gulls, half of which were in adult breeding plumage, and half immature of various ages. Amazingly, there were only 2 Ring-billed Gulls, which apparently have moved out in search of greener pastures, literally. And last, but certainly not least, was a first-cycle Great Black-backed Gull. One had been reported here about a month ago which I had missed, so I was especially happy to see it. A photo of this monster of a gull is below, on the right, with Herring and California Gulls to its left.

There was no sign of the first spring Mew Gull or the adult Franklin's Gull which have been tripping the eBird rarity filter all month.

You can view these birds through a telescope from a city utility easement just north of the inlet canal. I parked on a side street to the west, across Monroe St.

Subject: [cobirds] Arkansas Valley birding
Well, the middle part of the Arkansas Valley, anyway.

I took an enjoyable weekend trip, birding spots more or less along the Arkansas River from Canon City to La Junta over the weekend.

Friday, I was able to get away early because I could tele-commute by joining in on a 90 minute conference call (oh, joy!). That enabled me to get to Canon City by 7:00, early enough to finally enjoy the Riverwalk Western Screech Owl (oh rapture) that I've dipped on for at least three years (got that, Dan S.-thanks).

On Saturday morning, things started slowly with not much at the Holy Cross Winery or Lakeside (where's the lake?) Cemetery. I was disappointed to find that access to the Rufous-crowned Sparrow spot at Tunnel Drive is closed off. To quell my disappointment I headed up Temple Canyon Drive. I have a favorite spot up there a few miles-but I'm sorry I can't really describe it very well. In any event, it always seems to produce good birds. On Saturday I found a little side slot filled with scrub oak and junipers that held Spotted Towhee, Bewick's Wren, Plain Titmouse and Bushtit.

On my way to Pueblo, I birded near Wetmore. The Hardscrabble Valley north of Wetmore in Fremont County was very pleasantly birdy with a flyover Lewis' Woodpecker being a highlight. The rest of the day around Pueblo was not all that great as I couldn't come up with the winter resident Red-necked Grebe on the Reservoir or the early Sage Thrasher that Brandon had found a few days earlier.

Today I floated on downstream. I stopped at the Nepasta Road Marsh east of Boone (east of Pueblo). This is a spot that looks like it has great potential, and although the best bird I saw was only a Bald Eagle, I recommend visiting here to bird. Olney Springs "Reservoir", while not a reservoir looks like it has Tempel Grove potential a lot closer to Pueblo-my thanks to Darth Aves for making this a hot spot.

Lakes Henry and Meredith had lots of usual birds, but many displaying Clark's Grebes were a real treat. From Crowley County I slipped back toward Rocky Ford in order to head toward Holbrook Res. Well it's full of water, but not all that birdy (at least in a cold north wind without Stan Oswald around to chat with). I continued on to whatever that wet spot is at FF and 26 SE of Holbrook. Va-va-voom, it was great with lots of ducks, Greater and Lesser Yellowlegs and 4 Black-necked Stilts. Lake Cheraw was overflowing with water (maybe that will help with salinity issues?), but another disappointment as there was no shore for Snowy Plovers.

I continued on to Adobe Creek-Blue Reservoir (I use both names because it is in two counties). Almost all the bird action was in Bent where the "island" held single Franklin's and Herring Gulls as well as 8 American Avocets, and get this, contrasting groups of American White Pelicans and Snow Geese. That's usually a sign of spring, right? Passing from winter to spring means that we pass from Snow Geese to American White Pelicans. Well both birds were at Adobe Creek today; both seasons, too.

From Adobe Creek I headed north toward US 287 and home. Maybe not a good idea for everyone as the roads were a bit of a tussle. Birds, however as usual, were interesting. Cutting across that wide open space that you circle over and over if you've ever been delayed coming into DIA, it was clear that the three most abundant birds were Western Meadowlark, Horned Lark and .... American Kestrel. Kestrels were everywhere. But I will note in one very long stretch between Red-tailed Hawks, I tallied 2 Great Horned Owls, 2 Northern Harriers, 1 Merlin, 1 Prairie Falcon, 1 Rough-legged Hawk and the aforementioned hoards of kestrels.

A word to the wise-although canal fed bodies of water (Holbrook, Cheraw, Adobe Creek) are overfull, other water spots are dry. Long Lake NE of Adobe Creek which was a must stop last year is now a winter wheat field; Schafer is back to about what it looks like on Google-not the swan-hosting expanse that it was last spring. Well, that's what makes Colorado, Colorado!

Subject: [cobirds] Tues., Mar. 28, Boulder Audubon presents a program by Ted Floyd
This program is brought to you by *Boulder County Audubon*

7:15 p.m., Tuesday, March 28, 2017
Unitarian-Universalist Church
5001 Pennsylvania Avenue, Boulder
Free and open to the general public

*Birding and Birders in Boulder County: Past, Present, and Future*

Fifteen years ago, Ted Floyd moved to Boulder County. At the time, nobody
had ever seen a collared-dove in the county, nobody had Cackling Goose on
their life list, and nobody had ever heard of a Woodhouse's Scrub-Jay.
Times have changed: Today Bushtits swarm the county's eastern lowlands,
Black-chinned Hummingbirds are widespread breeders, and Lesser Black-backed
Gulls don't even raise an eyebrow. In this presentation, Ted will review
some recent changes to our avifauna, and he will gaze into his crystal ball
and tell us what lies ahead.


*Ted Floyd* is known for his passion for all things avian, amazing birding ear
and the erudite Editor of *Birding* magazine, published by the American
Birding Association, as well as the author of various books and articles
about birds and nature. Floyd serves on the board of directors for Colorado
Field Ornithologists, and is a frequent speaker at bird festivals and
ornithological conferences. He and his family live in Lafayette, eastern
Boulder County.

Observation start time: 08:00:00
Observation end time: 11:15:00
Total observation time: 3.25 hours

Official Counter: Mike Fernandez

Observers: Karen Fernandez

Visitors:
Approximately 6 parties of 1-4 people each made it up to the platform, but
no one seemed to be in a chatty or inquisitive mood. Very few even said
hello, but generally folks came up, took pictures and left without a word.
No cyclists.


Weather:
The first two hours we had sleet (frozen raindrops) and light rain. Rain
columns pushed from north to south along the foothills. The Rooney Valley
side and eastward did not appear to have the same weather as the Hwy 93
side. There was a little bit of sun lighting up the distant southeast
horizon; nothing but dark skies to the west. The sky cleared in small
patches briefly overhead right about the time our two migrating Red-Taileds
came through after about 45 minutes of no rain. After that, the sky
darkened, the ceiling lowered, waves of dark cumulus clouds moved in
overhead and hung above us and to the west. Sleet and rain restarted at
about 11:15 MST and unfortunately we ended the count after 3-1/4 hrs.

Raptor Observations:
When the rain paused briefly after the first two hours, all the local and
migrating Red-Taileds appeared within a 15 minute window. The first
appeared from behind Green Mountain, circled up, went north, paused and
circled above Table Mountain, then continued north to the limit of our
binocs. The second Red-Tailed also appeared from behind Green Mountain
circled up and north, then did a stoop back south, then a glide south back
up in elevation, then another stoop south; four times it did this
roller-coaster move until he led our eyes to a migrating Red-Tailed coming
up from southeast of the ridge. The local acrobat then alighted on the
telephone pole on the Rooney side above the motocross track.

Non-raptor Observations:
Seen or heard: White-throated Swifts (5), Northern Flickers (2),
Black-billed Magpie (1), Dark-eyed Junco (Gray-headed) (1), Spotted Towhees
(3), Western Meadowlark (1). Reported on eBird. Two Spotted Towhees flew
back and forth close to the ground on the north end of the platform between
junipers, scrounging up berries deep inside while it rained. Two mule deer
stared up at us from midway down the east side of the ridge.

Predictions:
The trail was in excellent condition on the way up and down, but if rain
continues it could be slick for Monday's climbers.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Brandon....thanks for the heads up.
All of the species you mentioned are to be expected. Maybe a tad early, but
that is the way our SLV migration has been going this year.
Always appreciate hearing about what others are seeing. It really helps
build the database I keep for SLV birds. See you down the trail...

Subject: [cobirds] Additional Black Phoebes plus Black Phoebe nest building in Canon City area
Yesterday I found an apparent second pair of Black Phoebes along the
Arkansas River near the MacKenzie Ave bridge. This is a location where
this species has nested for some years. They can often be seen from the
bridge on MacKenzie Ave but do be very careful as there is a lot of traffic
here and many are speeding.

Today I found a single Black Phoebe on private property where there has
been historic nesting.

Also today I observed a Black Phoebe gathering and bringing vegetation and
mud to a site I have suspected as a nest site but was unable to confirm in
previous years. I got photos of her and her mate who stayed nearby
including one with her in flight carrying nesting material. I have
uploaded these to my Birds and Nature blog
<http://birdsandnature.blogspot.com/>.

There are a few Turkey Vultures nesting in Canon City.

Observation start time: 07:45:00

Total observation time: 5.75 hours

Official Counter: Roger Rouch

Observers:

Visitors:
A serious younger birder stopped by to check on the daily count. Plus
several of the usual fair weather weekend hiker's checking out the view.


Weather:
A mild day with temps rising from the mid-forties to the low 60's F and a
breeze from the SE around 1 or 2 Bft. Clear skies to start the day, but by
mid-day it was mostly overcast with thin clouds and a light atmospheric
haze overhead.

Raptor Observations:
One or two naked eye birds with the remainder being binocular spots both
overhead and along the western ridges. A few more accipiters than previous
days and migration seemed a little later in the day. The overhead haze
limited visibility for high fliers. There was some local Red-tailed
activity in virtually all directions, but especially around Cabrini.

Non-raptor Observations:
A Canyon Wren was heard singing in the early morning and then in the
afternoon. About 15 or 20 White-throated Swift buzzed around Mt. Morrison
and twelve mule deer roamed the slopes around Cabrini. Black-billed
Magpie, Western Meadowlark, Common Raven, Woodhouse's Scrub-jay, Northern
Flicker, Spotted Towhee, Townsend's Solitaire, American Robin. And...a
vintage P-51 Mustang.

Predictions:
My predictions have not be very accurate this season, but it is probably
coming up on peak migration and it should be a good day.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Aiken Audubon had a field trip in Widefield Community Park and Crews Gulch
today in southern El Paso County.



Six birders made the trek noting signs of Spring everywhere and sighting
about 31 species. Frost covered the grounds when we started. We watched
a Belted Kingfisher at McCrae Reservoir proudly and loudly flying around
with a crayfish in its beak and enjoyed beautiful Song Sparrow song.
Heading through Widefield Community Park we had some nice birds - Lewis's
Woodpecker, Townsend Solitaire, Say's Phoebe, a Cooper's Hawk pair
returning to a previous nesting site, and we enjoyed watching some
Black-capped Chickadees excavating a hole for nesting. Robins were
plentiful and active all along the trail. In Crews Gulch we had possible
Scaled Quail, but unable to confirm. We saw Kestrels copulating down by
Ceresa Park.

This morning, while biking around Broomfield county, I stopped at Alexx and Micheal's pond (right off of Zuni and W 132nd Ave). The water levels were very low, which had attracted ten GREATER YELLOWLEGS, a very high count for the date, and just Broomfield in general. Also on the lake, were all three teals, six KILLDEERS, and one AMERICAN AVOCET. There was also two more avocets at Plaster Reservoir, and one YELLOW-RUMPED WARBLER along Big Dry Creek.

Subject: [cobirds] RFI American Three-toed Woodpeckers
Hello everyone! I am thinking about a quick trip to the front range April 21-24 with American Three-toed Woodpecker as the target bird. I have done some research on ebird that shows some recent sightings south and west of Sedalia and was wondering if those sightings would be relevant in late April, it is my understanding that the woodpeckers move into the higher elevations at some point but I don't have any idea when that timeframe is or how variable it might be.

Since this is going to be a quick trip in from my home in eastern Kansas I am only asking for front range tips and sighting info as south as possible as I plan on birding Morton county in Kansas on my way home (if the woodpeckering is successful!).

Thanks and have a great weekend!

This morning, Dave Wade, Austin Hess and I ventured east of our usual haunts in search of recently reported rarities. At Lower Latham Res, we struck out on Short-eared Owl and Great Black-backed Gull, but were greeted by friendly Virginia Rail and very photogenic Peregrine Falcon (see below) along CR 48. At Beebe Draw ponds along CR 40, the highlight was a drake Cinnamon x Blue-winged Teal hybrid (see below). At Stewart Pond, ninety minutes of searching 7 birders could not turn up the reported Eurasian Wigeon, although many other species (37) were present, including immature Tundra Swan (continuing) and a rare drake Northern Shoveler x Gadwall, which was too distant for quality photos. Nearby at Behrens Reservoir, early spring migrants Lesser Yellowlegs and Least Sandpiper (one each) tripped the eBird filter. David Chartier found the Least Sandpiper.

Official Counter: Debbie James

Observers:

Visitors:
Only saw 6 hikers/runners on the trail. One young man who had just moved
here from NJ to attend the Art Institute, stopped and talked. He was
shooting pictures.


Weather:
Boy was it blowing hard up on the Ridge. The trail was muddy and slick on
the way up, but I'll not bemoan a drop of precip for that poor dry
mountain. A nice powdering of snow, which remained on Mt. Morrison thru
the end of the day. Temps were 4 - 9 degrees (C), but wind made it feel
much colder. Pretty much a complete cloud covering the entire day. Good
thing about the wind was that it made for great visibility.

Raptor Observations:
Only the first 4 migrators were to the west over Mt. Morrison and on to
Mother Cabrini, but at the start of the 3rd hour all birds flew on the east
side of the Ridge, many at eye-level. It was a wonder to see Red Tail
Hawks hovering stationary in the high wind. Two locals played quite a bit,
hovering in tandem, legs down, heads down, then would roll and zoom to the
south. Bird fun! 5 local Red Tail hawks were spotted; 2 local Kestrels; 1
Peregrine Falcon; and 1 local Sharp-shinned Hawk.

Non-raptor Observations:
5 Black-billed Magpie; 3 Western Meadowlark; 4 Townsend's Solitaire; 8
Northern Flicker; 3 American Crow; 2 Housefinch; 2 American Robin; 2
Woodhouse's Scrub Jay; 17 Mountain Bluebirds; 1 Spotted Towhee; 15 Western
Bluebirds; 5 Bushtit;

Predictions:
Hopefully not so windy.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] Steve Bloom has passed away


Dr. Steve Bloom was Vice Chairman of Bird Conservancy of the Rockies
(BCR—formerly Rocky Mountain Bird Observatory). Steve was a founding member
of Colorado Audubon in 1999, serving as its President for three years. When
state chapters were disbanded in favor of regional organizations five years
ago, Steve joined BCR as a Director. He advised on the Big Strategic
Picture as easily as the nuanced details of leadership. Steve and his wife
Mike (Michele) loved birding, having seen over 3,000 species worldwide.

Steve was an organizational psychologist, most recently as a partner with
Somerville Partners. He was a psychological consultant to several of the
well-known Tier 1 and Tier 2 not-for-profit organizations in Colorado. His
attempt at retirement in 2011 was the only unsuccessful effort of his I
know about, caused because his clients kept calling him for additional
services. He previously served the state of Colorado as Director of Medical
and Mental Health Services.

An ideal consultant, Steve was a brilliant analyst of an organization’s
issues combined with a tact and gentleness that led to acceptance of his
suggestions. He also avoided the limelight, preferring to work behind the
scenes to help both organizations and individuals on leadership.

Steve will be sorely missed by BCR, his church, his family, his clients,
and his many friends. Thank you, Steve, for sharing with all of us your
life well lived. And thanks from me for your wisdom, energy, and wry humor
in our work together.

Subject: [cobirds] Early nesting Black-capped Chickadees, Loveland, Larimer Co.
During a visit this morning to the Guarantee Bank on the SE corner of
Lincoln Ave. and 29th St. in Loveland, we noticed a pair of Black-capped
Chickadees constantly flying back and forth to a rather obvious 2" nest
hole on the SW corner of the building. Their behavior certainly
suggested they are feeding nestlings already. The hole is about 12' up
in a stucco-like section of the wall. I suspect it may have been
excavated by a flicker attempting to create a nesting cavity. I thought
the combination of unusual location and early nesting activity made it
worth reporting.

I'd add to this that I saw 10 Turkey Vultures over Marjorie Perry Nature
Preserve. They appeared to be drifting east over (give or take) E.
Belleview Ave. While this is in Greenwood Village, it's near enough to west
Centennial to be pertinent to Kevin's observations.

Also at the preserve was my first Wood Duck of the year, several Red-tailed
Hawks, and a potential Say's Phoebe pair. (Are they paired up at this
point? I've seen two seemingly feeding "together" a couple of times at the

Observation start time: 08:00:00
Observation end time: 13:00:00
Total observation time: 5 hours

Official Counter: Mike Fernandez

Observers: Karen Fernandez, Mary Fran O\'Connor

Visitors:
Expert New York hawk watchers Liza and Ajit Antony (Mount Peter Hawkwatch
site in Warwick, NY) were on the hill from 8:00 to 11:00 MST and provided
numerous sitings. Former hawk watch volunteer Mary O'Connor came up at
12:30 MST and observed for an hour and a half. A visiting couple from
Massachusetts took a break from training for the Continental Divide Trail
and reported seeing lots of BAEA flying west along the I-70 corridor.


Weather:
Strong, sporadic wind gusts from the west all day. Otherwise, sunny and
clear with minimal high cloud cover.

Raptor Observations:
Local RTHA observed throughout the day on both sides of the ridge. A local
PEFA soared with a Red-Tailed Hawk above the platform. A migrant BAEA was
"escorted" by a pair of local RTHA from Green Mountain to Cabrini.

Non-raptor Observations:
Limited bird activity on the ridge today, perhaps due to wind. Observed
were American Crow, Common Raven, Townsend's Solitaire, Woodhouse's
Scrub-Jay, American Robin, Black-billed Magpie, and Northern Flicker.

Predictions:
Rain or snow should have an impact on migration. Or not.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] Poudre River area in Fort Collins e of Sharp Point and s of Prospect (Larimer)
Took a big walk from Sharp Point/Prospect east around Cottonwood Hollow and Running Deer Natural Areas in Fort Collins this morning. Out of a total field of 34 species, the "Sweetest 16", in chronological order, were:


Osprey (1 fixing up the nest atop the pole se of the Prospect Bridge, FOY for me)

Wood Duck (male flying over the Sharp Point Drive feedlot)

Killdeer (at least 6, already showing annoyance at entry into their territories)

Rock Pigeon (one had the rocks to sit on the Osprey platform between visits with sticks by the Osprey)

Northern Harrier (1 flying over Cottonwood Hollow, specifically the area known as Artist's Point Pond)

Western Meadowlark (full compliment seems to be back from points south)

American Coot (two pairs in nesting habitat)

Wilson's Snipe (1)

Virginia Rail (1 seen, another heard out in the Running Deer cattails, hormone levels high judging by their persistent vocalizing)


[cid:13772562-a2b3-4f85-a79e-9cbb3aadd612]


Belted Kingfisher (why are they so wary of adoring cameras?)

Green-winged Teal (2m, 1f, notably absent were their Cinnamon and Blue-winged relatives)

White-breasted Nuthatch (heard in the distance, interior race)

Common Raven (flew e over Running Deer from far to the west, checked for garbage at the Welcome Center out by Prospect/I-25, flew all the way back west)

Ring-necked Duck (1 handsome pair)

Mourning Dove (1 giving its namesake song in a sapling growing amid the cattails)

Cooper's Hawk (1 female flyover)


Other Observations

Swan (it's head was tucked away) was also present.
A Greater Yellowlegs was nearby in a ditch.

Hello Friends! I have moved from Colorado to New York and I am in need of some Mountain Chickadee singing video footage! I am working on a new bird song course at the Cornell Lab of Ornithology and I need to get my hands on video of a Mountain Chickadee singing the "fee-bee" portion of their vocalization. If you have any "fee-bee" video footage, I'd trade you that for a course: How to Identify Bird Song in the Be a Better Birder series! Please let me know and thank you!

Subject: [cobirds] San Luis Valley anseriformes, March 18-19
Hey, everybody.

Lots of ducks and geese this past weekend, March 18-19, in Colorado's San
Luis Valley.

At Monte Vista National Wildlife Refuge, Rio Grande County, on March 18,
Casey Setash and John Rawinski's apparent Graylag Goose x Canada Goose
hybrid was still there:

<https://lh3.googleusercontent.com/-U8Idr0zkTsM/WNPA8mN6IQI/AAAAAAAAWFA/vD47BEUKc7kMGolOnembSPP5rs61HKQwACLcB/s1600/4-18%2BGrxCd%2B1644.png>


One of the Redheads, a female, at Monte Vista showed extensive white on the
head:


<https://lh3.googleusercontent.com/-lHJbI7oSFzA/WNPBMQg_0rI/AAAAAAAAWFE/cBjSij96AtcDZx7qd44PwBJwj679-_eyQCLcB/s1600/4-17%2BRedh%2B1649.png>


There were thousands of white-cheeked geese, most of them apparently
Cackling Geese:


<https://lh3.googleusercontent.com/-ltofZ3sLa2I/WNPBeHL67FI/AAAAAAAAWFI/UTXaWR2DoYwEOHBNzeMZDrKLkjaCbO4ywCLcB/s1600/4-19%2BCacG%2B1823.png>

And there was a scattering of white geese, both Ross's and Snow:

<https://lh3.googleusercontent.com/-bablBWgMwV0/WNPBvLTwvBI/AAAAAAAAWFM/i4rph4KXQUQGB5MQVYoYrq9llHYx6rI8wCLcB/s1600/4-20%2BRoGo%2B1840.jpg>

Cinnamon Teal were back at the refuge. Over at Smith Reservoir, Costilla
County, there was a Greater Scaup with the hundreds of Lesser Scaup. Also a
Horned Grebe.

Some other odds and ends: Rough-legged Hawk, gazillions of Sandhill Cranes,
four species of owls at the Zapata Ranch (private), widespread Say's
Phoebes, a few Loggerhead Shrikes, Pinyon Jays, Woodhouse's Scrub-Jay, a
good Tree Swallow flight, Western Bluebirds in suitable habitat, Mountain
Bluebirds everywhere, Sage Thrashers, and Sagebrush Sparrows.

Subject: [cobirds] Black Phoebes, Eastern Phoebes, Turkey Vultures and Yellow-rumped Warblers in Canon City
I have one pair of Black Phoebes that are regularly foraging between Sell's
Lake and the Arkansas River for the past 6 days. I saw a single Black
Phoebe on the river two weeks ago but did not refind it. This pair often
forages near each other. I got a couple of reasonable photos of one of
them including one with a nice tail spread that I have uploaded to my Birds
and Nature blog
<http://birdsandnature.blogspot.com/2017/03/black-phoebe.html>.

I also found a pair of Eastern Phoebes returning to a nest site used every
year for past several years. The nest site is very vulnerable due to it's
location.

I spotted my first Turkey Vultures of the year 2 nights ago but have not
seen them since. There were only 3 or 4 birds in the group.

Yellow-rumped Warblers have been migrating through Canon City for the past
several days, just small numbers of them so far.

Also got photos of a couple of Wilson's Snipe that are on my Birds and
Nature blog.

Subject: [cobirds] Re: Possible Gilded Flicker, Fort Collins
Why not a hybrid red-shafted/yellow-shafted flicker? The 'hybrid' word is
dreaded, but in the flicker situation, a rather large percentage of
Northern Flickers through the Great Plains appear to be hybrids. I'm almost
surprised when I find a 'real' red-shafted or yellow-shafted because so
many seem to be odd mongrels. I've photographed a flicker within a hundred
meters of the Fort Collins Discovery Museum within the last couple years
that showed red-shafted head plumage, and yellow-shafted tail feathers
(possibly the same bird photographed by Nick?). Considering Gilded Flicker
is a sedentary saguaro desert beast which is almost strikingly smaller than
"Northern" Flickers, how would we detect a vagrant Gilded in northern
Colorado without a bird-in-hand at a mist net vs a photo? Which elements of
back and wing plumage distinguish Northern vs. Gilded? I can share a photo
of the presumed hybrid I have if anyone's interested, just give me a day or
so to find it in my files.
Good birding from hybrid flickerville,
Derek Hill

Subject: [cobirds] Bluebird Bonanza - Douglas
We walked the Walker Trail again this morning -- the Eastern Phoebe has staked out the section under the Colo. 86 bridge (at least today).

In the first big cottonwood grove we heard a sweet warble that Urling figured out: an Eastern Bluebird. The grove had two Eastern Bluebirds flitting around, and 3 (silent) Mountain Bluebirds, for at least an hour. Otherwise, the same contingent as yesterday. Meadowlarks & Song Sparrows House Finches singing.

Observation start time: 07:45:00
Observation end time: 14:00:00
Total observation time: 6.25 hours

Official Counter: Roger Rouch

Observers: Bill Wuerthele

Visitors:
Several hikers stopped by briefly to ask about things and many commented on
seeing some raptors along their hike. A couple from West Virginia stopped
to talk and watch. The gentleman had a nice camera and telephoto lens and
pictures of a hawk that looked probably like Ferruginous on the small LCD
camera screen and were taken south of the our site along the trail. (Not
seen or counted by us).


Weather:
A mild day with temps rising from about 40 f to the low 60's with a light
wind around 2 Bft. from the E and SE. Moderate ground level haze with
little hindrance to observation. As the day progressed, light haze also
developed to ridge line height with observations slightly obscured.

Raptor Observations:
Highlights included two Ferruginous Hawks with bright white wing panels and
tail that passed below eye level between the Green Mountain ridge and Dino
ridge. A Harlan's passed directly over the observation platform about
mid-day. There was a crazy flurry of local and migrating Red-tailed
activity mid to late morning along the west ridges mostly not far above
tree height with some below ridge and others disappearing behind the ridge.
At one time seven Red-tailed swirled together with five peeling off to
migrate and two locals returning to their territory. It's likely a few or
more slipped by the observers during this active time.

Non-raptor Observations:
Three Sandhill Cranes circled fairly low (at least low for Sandhills) just
south of the platform. Also, Spotted Towhee, Black-billed Magpie, Common
Raven, American Crow, Bushtit, Woodhouse's Scrub-jay, Northern Flicker,
American Robin, Townsend's Solitaire, Western Meadowlark.

Predictions:
Approaching front(s) could encourage more good raptor activity.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] Cherry Creek SP--Those ?? gulls
Hi:

The water was calm on Cherry Creek SP, not even a wave, just the small assortment of the usual ducks, so I decided to scope those annoying-looking gulls standing on the logs at the marina, adjacent to the dam in the northwest corner.
There were about 5-7 Herring Gulls and many, many adult Ring-bills and on one log was a smaller cluster of ?? gulls consisting of either first summer plumage Ring-bills or second winter California Gulls transitioning to a third or adult winter type plumage. Determining mantle color was hopeless as any small shift in position a dark mantle gull would turn into lighter mantled gull and the same was for a smaller gull shuffling on the log, would suddenly change into a larger one. The leg colors were neither yellow or pink just various shades of in between tones. Occasionally some would flap their wings and fly in circles screaming and shouting and return to the log. The upper tail consistently showed a thin, dark band at the end of the tail. The field guides seem to suggest that while it is possible for the California Gull, in latter stages of molt, so show this feature it would be more usual for the Ring-bills to show this thin dark band at tail end, So I concluded those ???? gulls were probably Ring-bills??

As I’ve learned the hard way there is nothing wrong with skipping those gulls at the marina and continuing down the road to watch colorful ducks dabbling in the smaller ponds.

Hi all

Someone mentioned this site today to me--for those who haven't it is an
interesting site. My advice to learn about project? Click "About This
Project" a short video introducing you to Google and Cornell project.

- https://aiexperiments.withgoogle.com/bird-sounds/view/

On the main page full of bird sound sonographs--think the (one of) aim of
the project was to group similar bird sounds closest to each other. Click
one graph then click its neighbors.

Subject: [cobirds] Fremont County Yesterday
Yesterday 3-21-17 I went with Michael Keissig down to Fremont County, it
was interesting and productive. Highlights at Brush Hollow Reservoir (both
east and west entrance) were Pinyon Jay, Canyon Towhee, Western
Bluebirds, Mountain Bluebirds, Scaled Quail, and Juniper Titmouse.
Highlights in Canon City, in addition to meeting Rich Miller, were Canyon
Wren, Eastern Phoebe, Black Phoebe (also several Say's Phoebe), a close
flyover Cooper's Hawk, and previously reported Western Screech-Owl. Did not
find Rufous-crowned Sparrow. We searched extensively for Sapsuckers without
seeing any, with several years data on my trips to the area I seem to find
more sapsuckers in January and February than in spring/summer/fall. In
Penrose we saw Wild Turkeys, Blue-winged Teal, an occupied Great Blue Heron
Rookery, and a fine-looking Lincoln's Sparrow. On I-25 north of Colorado
Springs, three Sandhill Cranes were going in one direction and then
another, acting like they weren't sure which way to go (or perhaps finding
the right wind current). Over 50 species on a day where I expected maybe 30
or so.

Subject: [cobirds] Birds on Baseline Reservoir this morning
Hi all -

I stopped by Baseline Reservoir to see what might be lurking out there this
morning. Highlights were a flock of Ruddy Duck (I counted 18), three
Horned Grebes, two of them males starting to show breeding colors, and a
lone Cinnamon Teal. The other usual suspects were there as well, a good
number of Hooded Mergansers, quite a few Gadwall, and a few Bufflehead and
Goldeneye. A couple of Killdeer were running around on the sandy areas on
the SW end, and the resident flock of Crows were there as well. All seen
from Cherryvale Road a little ways up from the south end of the res.

Good Birding -

I saw both of them today in the same spot. I'm not sure if this photos are
definitive, but I did view them for a while and they clearly had blue backs.

Subject: [cobirds] Western Field Ornithologists Pueblo Conference


Western Field Ornithologists (WFO) holds conferences throughout western
North America including Hawaii, the northeastern Pacific Ocean, and Western
Mexico. WFO is partnering with Colorado Field Ornithologists (CFO) to
bring this year’s conference to Colorado. It will be held at the Pueblo
Convention Center *August 16-20, 2017*.



Pueblo was chosen because it is near a wide variety of habitats. Pueblo
also gives attendees of the CFO convention in Steamboat Springs a chance to
experience a different part of Colorado in another 2017 birding convention.



CFO members have been a big part of putting this conference together.
University of Northern Colorado’s Lauryn Benedict, an expert on animal
communication and social behavior, will give the keynote address and a
workshop. Bill Kaempfer has been responsible for setting up field trips and
recruiting leaders. You’ll see new presenters along with some frequent CFO
contributors. In addition, you’ll see Forrest Rowland (head of Rockjumpers
Birding Adventures), and authors Jon Dunn, Kimball Garrett, and Jay
Withgott lead field trips.



WFO has set aside a block of rooms at the Courtyard by Marriott Pueblo,
located at 110 West First Street, Pueblo, CO 81003. The Courtyard is
connected to the Convention Center via a hallway. Unusual plus: those of us
elders whose “Search for Bridey Murphy” ended with a question mark might
find answers in the display at convention headquarters.



Make your hotel reservations at the WFO discounted group rate now with this
link: *https://tinyurl.com/zw83jlz*
<http://app.getresponse.com/click.html?x=a62b&lc=gTdzV&mc=Ck&s=XHPZli&u=BYPG&y=l&>
or call 719-542-3200.



The room rate is $98.00 (plus local taxes). We have a limited number of
rooms, so make your reservation soon.



For further information about WFO’s conference, check out
http://www.westernfieldornithologists.org/conference.php



In late March, we plan to announce and post the schedule for the
conference, including field trips and workshops. *Registration will open in
late April*.



WFO also is offering eight scholarships for youth aged 12 to 22.
Application deadline is April 5--so don't delay! More information is
available on the WFO website, or check out
http://www.westernfieldornithologists.org/scholarship.php
<http://www.westernfieldornithologists.org/conference.php>



We hope to see you there!

Hi everyone,

This evening after work, I headed to Parker Regional Park to check out a
couple of eBird posts on a Baird's Sandpiper. Although the photos aren't
great, the best couple I got are attached and are enough for documentation.

While there, I also what, by my best guess, was a Northern x Mexican
Mallard hybrid. I would love people's thoughts on whether that seems right.

I was leaving because the combination of an overcast sky with the late time
made for really poor lighting when I saw a meadowlark that struck me as a
little unusual, so I took a closer look and the best photos I could get. I
am reasonably confident that this is an Eastern Meadowlark based on its
mostly white malar, paler articulars, darker eyestripe, more streaked
sides, and more extensive white in the tail (seen briefly when it flew but
not even remotely successfully photographed, unfortunately). I found it on
the east side of the pond in the grassy area east of the dirt trail that
circles the pond. My pictures actually (to my untrained eye) looked
closest to Lilian's Meadowlark, so out of curiosity I did research online
and found this article
<http://cobirds.org/CFO/ColoradoBirds/InTheScope/27.pdf>by Tony Leukering
and Nathan Pipelow on the rare presence of Lilian's Meadowlarks in
Colorado. I would love to know if anybody has thoughts on this. Eastern
Meadowlark is a lifer for me!

Thanks!

Subject: [cobirds] Many Raptors on the move, 3/21 Mt Sanitas, Boulder
Dear Cobirders,
This afternoon my brother and I took a hike up Mt Sanitas and were treated with quite a raptor migration spectacle. We observed some on the hike up, but most were seen from the summit (12:30-2:30 pm).
33 RT Hawk
7 Buteo sp.
3 Sharp-shinned Hawk
1 Cooper's Hawk
3 Accipiter sp. (likely Cooper's)
1 Golden Eagle
2 Northern Harrier
3 American Kestrels
There were several RT Hawk groups of 3-5, some accompanied rising in the thermals by accipiters. It was very cool experience, the first time seeing so many migrating raptors from Mt Sanitas.
Good birding,
Thomas Heinrich

Total observation time: 5 hours

Official Counter: Gary Rossmiller

Observers:

Visitors:
Just a few people casually stopping by.


Weather:
Cool and hazy all day with increasing clouds. Horizons barely visible.
Completely overcast towards end of day. Falling barometer from 30.21" to
30.12" Breeze out of the N, NW direction starting at 3-4 bft ending at 1-2
bft.

Raptor Observations:
Locals fairly active. A solitary Coopers, Kestrel, and Sharp-Shinned Hawk
were welcome along with a small push of RT's between 11-12 MST. A Prairie
Falcon went by just as I got back to the parking lot, not counted. With
increasing cloudiness (poor light) and flight height it became difficult to
identify a couple of raptors.

Non-raptor Observations:
Meadow Larks heard all day on both sides of the ridge. An occasional Robin
and Townsend Solitaire heard. A few Magpies, Crows, Swifts, and Bushtits. 3
deer crossed the hiway early coming back to the ridge.

Predictions:
Hopefully with the high pressure system breaking up there will be more
activity.

Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] Eastern Phoebe - Douglas
On our morning walk Urling heard the distinctive call of an Eastern Phoebe, and later got a good look at the birds. It's on the Walker Trail, between the first foot bridge and the Colo. 86 overpass -- the same area where they probably bred last year.

Otherwise the selection seemed normal - though more birds than two weeks ago -- 20 species. Residents have started to sing: Black-capped Chickadees,W. Meadowlarks, & Song Sparrows. eBird deemed the Common Grackle as rare -- though I wouldn't.

Subject: [cobirds] Re: Cottonwoods Marsh, Walden Ponds Avocets
Yes, the avocets must have arrived just before I did, as they were there
when I walked out onto the boardwalk. I was hoping to see a Yellowlegs,
since one has been reported there recently, but Avocets were good, too (see
poor photo of three of them below). In addition, there were a few killdeer
and the Teal Trifecta, which is always a nice sight. The Say's Phoebe was
a nice little bonus, good thing Carl was there, as I didn't hear it.

good birding -

Spotted my first of the year Mountain Bluebird, hiking on north shore of
Gross Reservoir, 7600 feet. Not a record, last year I saw the first one at
Walker Ranch Boulder County, flying over the road, on 2/29/2016. But fun.
This male mountain bluebird was perching on a 5 foot bush, swooping to the
ground for bugs. Lots of bugs with the warm weather.
Very weak photo taken with iPhone, but best I could do.

Official Counter: Joyce Commercon

Observers: Hadi Soetrisno

Visitors:
Hadi Soetrisno, a HawkWatcher from the early days of Dinosaur Ridge’s
HawkWatch, spent the morning on the Ridge. His conversation and his help,
in spotting the few raptors that happened by, were very much appreciated.
Most other visitors to the Ridge were there only for the view or had lost
the path descending to the parking lot. One couple, however, that was met
on the trail in the early morning, was interested to know about the raptor
monitoring, and was curious to know if we were seeing Golden Eagles, Bald
Eagles and Turkey Vultures yet.


Weather:
The day was very warm with temperatures rising from 17 C to about 26 C
during the watch. Winds were initially mild from the east and southeast,
but became stronger (bft 3-4) and shifted to come from the west just before
noon MST. Cloud cover increased from 40 to over 90 percent. Thicker, often
grayer, clouds eventually replaced the patchy mix of flat cumulus and thin
cirrus clouds that paraded during the morning hours. Visibility was very
good.

Raptor Observations:
It was a slow day for migrating raptors. The highlight was an adult Bald
Eagle (spotted fairly high over Rooney Valley) that migrated northwest past
Bare Slope and Lookout Mountain. A good view of a northward-bound male
American Kestrel in the afternoon was also appreciated. Also in the
afternoon, a local adult Golden Eagle passed north of the HawkWatch site as
it moved eastward from West Ridge to Green Mountain and beyond. The local
Red-tailed Hawks were scarce early in the morning but became much more
active as the day progressed. Mostly, only one was seen at a time:
hovering, kiting, hunting—up and down the valleys, over Green Mountain and
the western ridges from Mount Morrison to Cabrini. Near the end of the
watch, one of the pair was observed to circle up from the trees along Mount
Vernon creek at Matthews/Winters Park. With a full crop, it headed
northwest, leisurely performing some shallow roller-coastering along the
way. Shortly afterward, the second of this presumed pair was seen still
hunting in the same valley; it soon also headed northwest.

Non-raptor Observations:
A Canyon Wren was heard twice today. A pair of Common Ravens rode the
increased winds near noon; one displayed its prowess by doing several
backflips. One of the many American Crows spotted today appeared to have
small white patches near its carpals. Also seen or heard were Spotted
Towhee, Woodhouse’s Scrub-Jay, Townsend’s Solitaire, Rock Pigeon, House
Finch, Western Meadowlark, Black-billed Magpie, Dark-eyed Junco, Northern
Flicker, and Western Bluebird.

Subject: [cobirds] Possible Gilded Flicker, Fort Collins
I observed what may have been the same individual bird at the Museum feeders twice in December 2015 and once in January 2016. Each time I recorded the observation in eBird as an intergrade Northern Flicker with red malar but yellow shafts. I don't carry a camera when birding, so no images to share.

I am unclear whether this definitively supports or refutes Nick's theory of a possible Gilded Flicker. The principal pieces of scientific evidence in support of Gilded would be:

1) I've always maintained that if I ever had the good fortune to see a first state record, I would surely mis-ID the bird; and
2) I once said to Nick with no evidence whatsoever (though he wouldn't remember this) that I figured there had been Gilded Flickers seen in Colorado, just not properly identified.

Subject: [cobirds] Lincoln's Sparrow, COS, El Paso Co Mon
Hi COBirders,

Just caught/banded my FOS Lincoln’s Sparrow in the yard in Mountain Shadows, NW Colo Spgs. Earlier than usual!

I am getting very few yard birds right now. I assume they are not congregating the same way since weather hasn’t chased them to feeders, but I have seen a 100% turnover in the juncos in the yard. None are around that I banded earlier in the season.

We have been seeing migrating accipters here at the edge of the foothills, and had an adult F Cooper’s Hawk dispatch and dismember a collared-dove in the yard Saturday. Got some pretty good bloody close-ups!

Spring is here!

Subject: [cobirds] Re: Pacific Wren at Grey Rock Trail, Larimer County
Greetings birders,

On Saturday Nick Komar, Austin Hess and I joined forces to search for the
Pacific Wren that Francis had found earlier in the week. After several
hours of enjoyable searching, where we heard several Canyon Wrens sounding
their cascading call and found at least 3 American Three-toed Woodpeckers,
our team finally located the elusive little bugger! We were strung out on
the trail heading down when Nick and Austin heard a sharp "csik csik"
coming from the small creek down below the trail. I never heard it but
fortunately, I was in the best position to get close to the stream and did
so, close to where Austin thought it might be. After a few minutes Nick
finally spotted it and I was able to capture some good pictures of it... go
team!

For those interested in searching, concentrate on the small creek that
flanks the Summit Trail on the right as you climb up towards Greyrock. The
trail crosses this small stream twice, lower on the trail and in the place
Francis described. I would recommend searching this section of the creek.
We found it downstream of the area Francis described. Thanks and Good luck,

David Wade
Ft Collins, CO

----------------------------------------------------------------------

Observation start time: 08:00:00
Observation end time: 14:00:00
Total observation time: 6 hours

Official Counter: Mike Fernandez

Observers: Karen Fernandez

Visitors:
A busy Colorado morning with almost all hikers and families (very few
bikers). No elk or deer spotted. A trail runner who spent some time
observing with us had some curiousity and stated he talked with HawkWatch
members during the on-the-hill orientation this year. New Jeffco open space
ranger appeared but was not conversational.


Weather:
Warm, sunny and dry with a steady breeze for the duration. "Sunshine" fire
west of Boulder did not seem to impact visibility. Criss-crossing aircraft
con trails all day helped share sightings. Winds shifted to the west and
south at noon, seemed to move some fliers from west to overhead, but
shifted back to ESE soon after. Most sightings today were over western
ridges or very high directly above.

Raptor Observations:
Overall, a neck aching, arm numbing day; we needed a Lazyboy on the ridge!
Back to reality: A diffifcult day for raptor-at-elevation identification.
All day, raptors tended to ride thermals starting south of the ridge, a few
then dropped down to low west of ridge, ride another up in front of Two
Pines and then spiral north over Apex and Lookout towards Boulder. Others
disappeared above 10x binoc limit. Two wide-area local RTHA appeared
several times AM & PM circling over Green Mountain. Four likely BAEA (ID:
shape of wing) circled high over Mt Morrison mid AM but ID was compromised
as they reached the limit of 10x binocs and we did not see them proceed
north of Mount Morrison; not counted. Either a Rough-Legged Hawk or
Ferugginous Hawk appeared at south end of ridge (late AM mst), rode up to
limit of binocs then northwest to Power Lines and then, unfortunately,
behind horizon at Subpeak, although consistently moving northward; counted
as Unkown Buteo. All day we observed several red-tailed hawks of "migratory
status undetermined" (they may be locals of a wider area, but they were not
the nearby locals we know) rise beyond sight above us and their movement
from there was not perceptible.

Non-raptor Observations:
Non-Raptors seen or heard (and reported on eBird): Northern Flicker (2),
Woodhouse's Scrub-Jay (2), Black-billed Magpie (5), American Crow (13),
Common Raven (5), Black-capped Chickadee (1), Bushtit (1), Townsend's
Solitaire (1), American Robin (2), Dark-eyed Junco (1), Western Meadowlark
(1) and House Finch (1). No observations of elk or deer today.

Predictions:
Scope recommended, as noted in previous submissions. What about setting up
a loaner to check out at the Dinosaur Ridge Discover Center? Their hours
through April are Monday through Saturday 9:00 AM to 4:00 PM and Sunday
10:00 AM to 4:00 PM, then open till 5:00 PM in May. Not ideal but could
make it work.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

I photographed a Flicker last Wednesday evening at the feeder behind the
discovery museum in Fort Collins that seems to have traits of Gilded
flicker. Whether this turns out to be Colorado's first Gilded Flicker,
normally a resident of riparian habitat and desert in Arizona, or not
remains to be seen. Elements in the tail, the back and wings and head
suggested Gilded Flicker although the head pattern is somewhat confusing.
It might be a hybrid between Gilded and red shafted flicker but even in
that case I think it's mostly gilded. Here's a photo.

Subject: [cobirds] Carolina Wren in Pueblo 3/18-3/19
A Carolina Wren that has been around Pueblo since 2016, has starting
singing again. It is well east of Pueblo City Park, along the south
side of the Arkansas River. It was seen both today, and yesterday.
Also, yesterday there was a Winter Wren again in this area. These
birds are no where near Lake Pueblo State Park and Rock Canyon Picnic
Area, so if there is another Carolina Wren singing there yesterday,
that is certainly a different bird.

Other birds of interest I heard about, around Pueblo this morning,
were a Long-tailed Duck and a Black Phoebe . Also, a Red-necked Grebe
continues at Pueblo Reservoir at the North Shore Marina.

Adams County seems to have dropped off the CObird rare bird report. I know a Lesser Black-backed Gull had been seen at Barr Lake this month.
Are there truly no further reports of rare birds? Do I need to go find some?

Hi Everyone, 
Today 3/18 I drove around Union Reservoir. Best birds were 3 Bonaparte's Gulls seen resting with Ring-billed at the NW corner, and later flying around the south end. The reservoir is full of Horned and Eared Grebes now. Duck numbers are down. No swallows yet, but soon.

Subject: [cobirds] Continuing Ross's Goose & Others - Greenwood Village (Arapahoe)
After a sunrise walk at Marjorie Perry Nature Preserve (Virginia Rail,
Ruby-crowned Kinglet, & Western Meadowlark were the most notable birds), I
made a quick stop at West Middle School (S. Holly St & E. Belleview) in
Greenwood Village (Arapahoe Co.) to check on the Ross's Goose, which was
still grazing in the baseball fields and near the track along with Cackling
& Canada Geese. It's been doing that at the school since at least February
23.

Afterward, I walked Westlands Park (also Greenwood Village) to see if I
could turn up the sapsucker that Chris Blakeslee reported yesterday flying
out of his yard and in the general direction of the park. I didn't find it.
A pair of Killdeer, my first at Westlands, were calling and flying over the
largest pond at the park.

Back home, the local pair of Red-tails flew together over my Centennial
yard, calling madly at each other. Later, on an afternoon trip to the
grocery store, I spotted a Common Raven at the Streets of Southglenn
shopping center (University & Arapahoe in Centennial). This expansive
outdoor mall is, in my limited experience in the area, the best spot to
find ravens in west Centennial.

Observation start time: 09:00:00
Observation end time: 14:00:00
Total observation time: 5 hours

Official Counter: Mitchell Blystone

Observers: Graham Hill, Terry Escamilla

Visitors:
Having Terry and Graham on the hill helped immensely! More observant eyes
and the scope helped us up the count. Typical weekend traffic with a some
curious hikers asking questions. There was a lot of activity at the motor
track.


Weather:
HOT and DRY!!!! The morning began very warm with a slight breeze from the
south. Lots of sunshine and only high cirrus clouds which did little to
shade the ridge. The winds eventually came out of the southeast and became
more moderate than calm.

Raptor Observations:
A very quite morning with no sighting of even the locals until around
10:30am. Eventually the local active became near constant along the
Cabrini hillside and western ridge line. Some of the earlier migrating Red
tails were observed moving through the east valley and were slightly above
the platform. The later migrators including the falcon were very high up
and difficult to ID as well as follow. Two Red Tails took nearly identical
flight paths high along Mount Morrison and where barley visible when they
moved over Golden. There were a couple distant observations of what seemed
to be local Kestrels and even Accipiters but they were too distant to
confidently identify. A day of having to work hard for any kind of
observations!!

Non-raptor Observations:
Many Townsend's, Magpies, Robins, Crows, and Ravens. There were a handful
of Towees (Spotted?) early on in the day and a couple times while observing
raptors there seemed to be White Throated Swifts moving quickly by but they
were distant and hard to follow.

Predictions:
Looks to be hot again so bring sunscreen and lots of water. A lot of the
migrating birds still seem to prefer to be high up along the Mount Morrison
ridge line. A scope would greatly increase your chances at identifying
these high flyers!
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

All,

Not to be shown up by Fort Collins, the Harris's Sparrow in Westerly Creek
Park was seen by Steve Stachowiak, a lady from Boulder, myself and John
Drummond. It was first seen with a flock of White-crowned Sparrows in some
shrubs on the west side of Beeler near 26th St, and later back on the east
side of Beeler by 25th St.

Cheers, Peter Gent.

Subject: [cobirds] Summit, Douglas
We spent the last 3 days in Summit County -- no robins, but 10-20 Evening Grosbeaks -- a species we don't see mentioned on Cobirds very often. Otherwise, the typical Summit birds including what once seemed atypical -- several flocks of Pygmy Nuthatches. A grand total of 19 species seen on 5 walks on beautiful sunny days -- walks on top of the snow.

This morning, back at home, our daughter Anne spotted two Western Bluebirds inspecting a nest box. Although a scrub-jay scared them away, we still hear them clucking somewhere nearby. Close to 19 species right here today. . . .

Yesterday evening I went out to try and re-find the Red-shouldered Hawk
with no luck.

While walking around the small wetland we got good looks at a 1st winter
Harris's Sparrow perched in what seemed to be a hawthorn. This bird had
whitish tertial feathers along the edge, light bill and a white belly along
with a thin necklace. It was feeding on some unidentified insects on the
new hawthorn buds.

Good birding,

What a day! 7 local Redtail hawks were spotted, two appeared to be mating
in the first hour. 2 local Kestrels. Had at least one migrating hawk
every hour, with the 1000-1100 hour having 12! It was nice seeing Coopers
and Sharp-shinned today. Some of the raptors were flying so high and far
over West Ridge, that without a scope, we weren't able to identify the
species.

Non-raptor Observations:
No mammals spotted today, but bird-wise there were 6 Black-billed Magpie;
44 American Crows; 3 American Robins; 2 Townsend's Solitaire; 2 Western
Meadowlark; 3 Western Scrub Jay; 2 Chickadee (species) heard; 1 Flicker; 25
Bushtits; 1 Housefinch; 25 Rock Pidgeons; 1 Common Raven

Predictions:
Going to be a HOT one tomorrow. Hopefully hawks will find it as amenable
to migrating as they did today.

Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

COBIRDERS,
We had a young sapsucker in our backyard this afternoon. It quickly flew off north toward Orchard Road just west of Quebec.

I think it is an approx. 10 month old female Yellow-bellied Sapsucker. Please tell me if I am correct or if it is a Red-naped Sapsucker.

Thanks much! Chris

A quick trip to the Monte Refuge showed numbers way down from the previous
week. During the entire past week we have had favorable weather for
migration and birds have been leaving by the hundreds. My home is in the
area where they spiral upward until they are WAY up there and then they
catch a tail or side wind and are gone until next fall. Cackling Geese
seemed to have vanished overnight. Migration waits for no one....on

Yes, I'd check the ten day forecast for each of the towns near where you
will be birding and check it again daily
and you'll have a good idea.

We always say, dress in layers. If you will be out of the cars at those two
passes, you'll basically need to where ski
clothes - polypropylene under layer, warm middle layer, windproof shell.
gloves, warm hat.
Good luck.

Hi Mary,

I'm a MA Audubon member living in Colorado near Boulder; I travel to
CapeCod most Septembers.

Prepare for anything! This week we are having temps in the 60's and 70's.
That could be true when you are here, or we could have a foot of snow. I
suggest looking at the weather forecast prior to coming for the period
during which you will be here and plan accordingly..

Enjoy your trip,

Marilyn

Subject: [cobirds] Tues., Mar. 28, Boulder Audubon presents a program by Ted Floyd
This program is brought to you by *Boulder County Audubon*

7:15 p.m., Tuesday, March 28, 2017
Unitarian-Universalist Church
5001 Pennsylvania Avenue, Boulder
Free and open to the general public

*Birding and Birders in Boulder County: Past, Present, and Future*

Fifteen years ago, Ted Floyd moved to Boulder County. At the time, nobody
had ever seen a collared-dove in the county, nobody had Cackling Goose on
their life list, and nobody had ever heard of a Woodhouse's Scrub-Jay.
Times have changed: Today Bushtits swarm the county's eastern lowlands,
Black-chinned Hummingbirds are widespread breeders, and Lesser Black-backed
Gulls don't even raise an eyebrow. In this presentation, Ted will review
some recent changes to our avifauna, and he will gaze into his crystal ball
and tell us what lies ahead.


*Ted Floyd* is known for his passion for all things avian, amazing birding
ear and the erudite Editor of *Birding* magazine, published by the American
Birding Association, as well as the author of various books and articles
about birds and nature. Floyd serves on the board of directors for Colorado
Field Ornithologists, and is a frequent speaker at bird festivals and
ornithological conferences. He and his family live in Lafayette, eastern
Boulder County.

The Red-necked Grebe that has been present since January, continues at
Pueblo Reservoir yesterday (15 March) and today (16 March). The bird
is almost completely in breeding plumage now! Not much else new going
on new. Two Common Loons at the Reservoir yesterday, eight Cinnamon
Teal today. Four Ospreys today in the State Wildlife Area in the NW
side of Pueblo Reservoir. Still waiting to see some of the spring
migrants that seem to be showing up everywhere else. I'm sure they
will come here at some point.

*Brought to you by Boulder County Audubon.* This popular series of field
trips entitled, "Interludes with Nature", features the very best leaders
taking participants to special places. It is a major fundraiser for BCAS
and the proceeds send budding teen naturalists to either the superb
National Audubon Society's Hog Island Field Camp or to the American Birding
Association's, Rocky Mountain National Park Birding Camp. This year we
have awarded 3 scholarships to outstanding youth.

We are requiring full payment within 8 days of emailing me for a
reservation: <piombino.pam...> If I do not receive payment within
the 8 days, your name will be put on the Wait List. If you have to cancel,
there will be a $20.00 fee imposed. If you cancel less than three weeks
before the event, the money will only be refunded if the spot can be
filled, but there will still be a $20.00 fee. Please consider it a donation
for the fine work that Boulder County Audubon does and how much work it is
to arrange these trips and keep track of the attendees. Once you make a
reservation, *please, please get the pertinent information on your calendar* to
keep track of which trip(s) you have asked to participate in.

Subject: Re: [cobirds] Re: Grandview Cemetery in Fort Collins (Larimer) on 15March2017
Regarding eBird flags, I will play Devils Advocate. Tripping the filter does not imply "rejection" (Derek's word) or dislike (Dave's word) on the part of eBird. Flagged observations are almost certainly welcomed by the eBird team as these unusual observations represent NEW knowledge about bird populations, and eBird is all about characterizing bird populations. Observations that are not flagged add little to current knowledge (but are nonetheless valuable). When I go birding, I like to trip the eBird filters because I know these flagged observations are contributing to NEW knowledge of bird populations.

EBird is improving with time. I'm glad the filter caught the early Turkey Vulture. Surely Dave's comment in response to the flag will convince the local reviewer to accept this noteworthy observation. If Derek also eBirded his early tV observation, and if others did as well, and these early reports prove to be more than an anomaly, the filters will eventually be altered to reflect the new reality.

However, as Dave points out, the real anomaly -the misplaced Marsh Wren- was missed by eBird as being unusual. This is because the man-made filters are by necessity regional, referring to an entire County, or part of a county. Eventually, I believe that eBird will be able to convert to site-specific computer-generated filters. If a filter is tripped when an observation is rare (say, with 5% probability or less), and there are 100 checklists submitted per week for a site (roughly 5000 checklists total), then there would be enough data for the computer to determine which observations are unusual for each week. Currently, Grandview Cemetery has 635 checklists.

So the moral of the story is this: if you don't like the man made filters in eBird, submit more complete checklists to eBird. If we all did this, we could convert to an unbiased computer-generated filter system sooner rather than later.

Subject: [cobirds] Pacific Wren at Grey Rock Trail, Larimer County
This morning I took a new birder out to Grey Rock Trail up the Poudre
Canyon. In addition to a pair of AMERICAN DIPPERS clearly engaging in nest
building activities where the trail crosses over the Poudre River, we found
a skulking PACIFIC WREN along the summit trail, just where this trail first
crosses the creek as you hike northward and upward. The habitat was of
dense dead grasses and weeds and tangles of shrubs along the banks of the
creek. The bird called loudly in agitation as we crossed the creek. I
recorded its call with my iPhone and later confirmed that it was indeed a
Pacific Wren (not Winter, because of higher and more terse notes). The
compact little hazelnut-brown bird popped out into view and gave
spectacular looks. Very faint eyeline, tiny stubby tail, ventral side just
about as cinnamon brown as the dorsal side and definitely no white on the
throat. It even sang two rounds of its gorgeous song up close!

Its cousin, the Canyon Wren, sang loudly from a nearby cliff and a female
Hairy Woodpecker knocked away at a burnt Ponderosa fervently. Pygmy
Nuthatches squeaked and flitted about in the high pine boughs. A flock of
Steller's Jays gave my hiking partner stunning views; a Townsend's
Solitaire serenaded us from just up the hill. And the sun shown strongly
upon the land as the soil came alive with ants, spiders, wasps, and even a
millipede. We are fortunate to have inherited such a marvelous world.

eBird should probably not reject your Turkey Vulture sighting. I was

Subject: [cobirds] Grandview Cemetery in Fort Collins (Larimer) on 15March2017
Exciting day at Grandview Cemetery, west end of Mountain Avenue, Fort Collins. eBird didn't like the Turkey Vulture that flew thru at treetop level, even though they always come back in March and there's been a colony a few blocks east of the cemetery for decades. I would call the date about "a week early" from the norm. I don't have access to the late Dr. Alex Cringan's data on their local return date. In its infant wisdom eBird did NOT flag a bird I have never seen there in 1700+ visits: Marsh Wren. That's species #198 for me at the cemetery. It was in the alley east of the cemetery foraging at the base of a fence overgrown with Virginia creeper vines. I got wonderful photos with a camera that told me afterwards ("no card"). Drat. Saw a Cooper's hawk eating a collared-dove in the middle of the street. Lots of adult hackberry gall-making psyllids out and about, freshly emerged from their overwintering haunts in the bark. A brown creeper, no doubt not alone, was nitpicking them. Barring a super cold, fast-ascending storm, when we return to sub-freezing temps again, these little insects will return to the bark. If it were to stay warm they would mate and lay eggs on the developing buds of hackberry. A bushtit and a couple black-capped chickadees were gleaning golden oak scales from a bur oak. Bushtits were also getting aphids from a pinyon pine and marauding thru various other plants. To paraphrase the Peace Corps slogan, mama great horned owl was carrying on at "the most boring job you'll ever love" (incubation). Total of 17 species.

Observers:

Visitors:
None.


Weather:
Partly cloudy, calm and seasonably warm, if not hot. A breeze from the NE
around 0-1 Bft. early then from the NW around 1-2 Bft. Temps rose from the
lower 50's to lower 70's.

Raptor Observations:
Raptors appeared to enjoy the good thermals of a warm calm day. Of five
migrating, four were "at the limit of 10X binoculars". Local raptor
activity was relatively light. Three or four probably local high spiraling
Red-Tailed were lost in the blue or clouds before any sense of flight
direction could be determined.

Non-raptor Observations:
Also seen were Black-billed Magpie, Common Raven, American Robin,
Townsend's Solitaire, Western Scrub-Jay, Mountain Chickadee. A band of
eight or ten Bushtit twittered through the brush in the afternoon.

Predictions:
The schedule doesn't show a counter for tomorrow, Thursday. If the calm
and warm weather persists, a guess would be for high fliers as thermals
develop.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Hi

I will be heading out with a MASS Audubon group for a week of birding, mid
April. We'll begin in Denver and move onto Fort Collins, Walden, Craig,
Silverthorne, Gunnison, returning to Denver. Itinerary includes viewing
three leks (Greater Sage-Grouse, Sharp-tailed Grouse and Gunnison
Sage-Grouse) as well as traveling through some high elevation, such as,
Cameron Pass and Loveland Pass.

A few years ago, I traveled out to Oklahoma same time of year, and was a
bit surprised by cold weather. I understand weather can vary but I want to
be prepared as possible.
So looking for information on what possible weather we might encounter -
temperatures, high and lows, precipitation, icy conditions - and any other
helpful advice.

Looking forward to visiting Colorado. First time.

Thank you for your time.

Hi all,


I saw a beautiful Peregrine Falcon land on the north side of Marston Reservoir today. The bird was perched on top of a tree branch trying to get it's balance. The wind and wind gusts were pretty strong still. Then the Falcon took off to the north. Every year I see one or two Peregrines stop off near Marston reservoir. Saw one try for a duck once.


Marston Reservoir is accessible from Bow Mar Dr.[the east side], or from[ the west side], from Old Wadsworth Boulevard.


Happy Birding!

Observers:

Visitors:
A few people stopped momentarily on the platform.


Weather:
Overcast gave way to mostly sunny. Another windy day, gust up to bft 7
making it hard to track with 10x binoculars. Winds died down to bft 3-4 the
last hour and a half. Wind mostly out of the W or NW. Slightly rising
barometer 30.10 to 30.13. A lot of dust in the air, sun dog in the
afternoon.

Raptor Observations:
Very slow day, a couple of pairs of local RT's worked both sides of the
ridge actively. Locals would get my hopes up then turn around. Mystery
buteo after 1pm, very rufeous chest but flew like a RT, will count him as a
UB. Female kestrel just above the bushes on the west side late in the day.

Non-raptor Observations:
6 deer very close to the trail on the way up with 9 more lower on the west
side of the hill. Scrubjays were fairly active early, a magpie, robin, and
townsend solitaire were seen or heard. Otherwise, nothing. A solitary swift
late in the afternoon getting buffeted.

Predictions:
Hopefully more active!!
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Stopped briefly at the small pond on 109th Street and Boulder Creek this morning. Two male Blue-winged Teal were on the pond, but flew as I watched.
At Panama Reservoir #1, Ted Floyd’s Horned Grebes (52) were still present. Some were in winter plumage while others were sporting breeding plumage. Among the many Common Mergansers were 6 Red-breasted Mergansers.

Subject: [cobirds] Monte Vista Crane Festival last weekend
The Sandhill Crane migration is in full swing in the San Luis Valley. I
was there during the official festival weekend and saw the expected
thousands of feeding, loafing and flying cranes, geese and ducks. Always an
amazing spectacle.
Four unexpected sightings were:
- Seeing a dozen Bald Eagles congregate into a thermal just north of Home
Lake late Friday morning, ride the air up and head north.
- A very leucistic Red-tailed Hawk hanging around near the intersection of
Roads 8S & 5E, reported by others later as being harassed by a
Rough-legged Hawk. The bird had a few random dark feathers and an orangey bill. A
friend got pictures that I'll share with anyone who's interested.
- A lone Tundra Swan seen Friday evening in the ponds along Colo 15 just
south of the old Refuge HQ, seen again flying the next morning.
- An extended flow of cranes from the south Sunday morning, apparently
they'd flown up overnight from the Bosque del Apache region. Line after line
(do we call them skeins when they're cranes?) of birds appearing as dust
flecks in binoculars trained on San Antonio Mountain, a new line appearing
every few seconds for the two hours I watched, getting closer and closer till
visible with the naked eye. I've seen the feeding flocks and flyouts many
times over the years, but this is the first time I've experienced a
massive influx of cranes migrating up from the south. It was something to behold.

Subject: [cobirds] Loveland Gulls (Larimer)
Nick Komar and I headed down to Horseshoe Lake in Loveland this evening to
pick through the gull flock. It was a very good day with about 8 species
found, although we did not find the Great Black-backed Gull. When I saw
the Mew Gull I reported yesterday had been rejected by ebird (I wasn't sure
if we misidentified the bird or just didn't provide enough evidence with
poor photos and even worse details) I became determined to study first
cycle Ring-billed Gulls to see if I had actually misidentified yesterday's
bird in sub-optimal conditions. Unfortunately, there aren't many young
Ring-billed Gulls around, but I did find a very similar looking bird which
was a first-cycle MEW GULL and made me more confident in our identification
yesterday. I guess it is better to include more details on the bird and
fewer hashtags in eBird descriptions. We also found the continuing (bird
that has been reported as an) ICELAND GULL along with four THAYER'S GULLs
(if you believe in those). The Iceland Gull was pretty distant, and I
never personally saw any barring on the tertials although everything else
seemed to fit for what people call Iceland Gulls out here. There was also
a very pale Thayer's Gull around, but the primaries were much darker than
the Iceland Gull's primaries. We also had a couple of early FRANKLIN'S
GULLS and 14 LESSER BLACK-BACKED GULLS in the flock of 1500-2000 gulls. We
only birded the southwest corner of the lake.

Good Birding!

Subject: [cobirds] Harris's Sparrow got lucky today
The Harris's Sparrow was present today, around 5:30 pm, same location,
between E 23rd and 24th Ave. While watching this bird foraging on the
ground, kicking around leaf litter, an accipiter (Coopers or Sharp-shinned)
flew in so fast and almost had that sparrow for dinner. After that, it
stayed well hidden inside a thick bush. Wise move if it wants to make it
another day.

Observation start time: 08:30:00
Observation end time: 15:00:00
Total observation time: 6.5 hours

Official Counter: Joyce Commercon

Observers: Nancy Kranzow

Visitors:
There were a fair number of hikers and bikers on the trail today. Only a
few hikers came up for the view; all waved or gave a greeting but none
seemed interested in raptor monitoring.


Weather:
The day was partly sunny with cloud-cover shifting and increasing during
the watch but never completely covering the sky. In the morning, long thick
strips of cloud formed above the western ridges; these clouds then moved
east to hang over Dinosaur Ridge and the valleys, staying reasonably
parallel to the ridges. Winds were mild and came initially from the east
and southeast but shifted to come predominately from the north after noon
MST. Temperatures rose from 6 C to 16 C. Visibility was good.

Raptor Observations:
Lots of Red-tailed Hawk migrants again today! The 11:00 am MST hour had the
most: 9 Red-tailed Hawk migrants; there were two groups of 4 and 3 hawks,
respectively, plus a couple of loners. Each group migrated north almost
directly over the Ridge. Earlier in the morning we had the pleasure to
observe a dark-morph adult Red-tailed Hawk pass north over the Ridge. Other
notable migrants today included a juvenile Ferruginous Hawk, which was
spotted migrating north along the western ridges, and a juvenile Golden
Eagle that came north right along the Ridge, giving us a good look at it.
The spot of the day goes to Nancy for catching a high-flying falcon that
turned out to be a Prairie Falcon migrant.
When the winds shifted to come from the north, the migrant flow dropped to
a trickle. Still, the local adult Red-tailed Hawks were out and about. In
the afternoon, there was much circling and hunting. One of the pair finally
did manage to snare a weighty prize in Rooney Valley and was seen lugging
it southwards.

Non-raptor Observations:
A pair of Common Ravens landed on the power poles, croaking and clicking,
presumably to each other. At the end of the watch, about 20 Bushtits passed
north on the east side of the Ridge. Also seen or heard were American Crow,
Spotted Towhee, American Robin, Black-billed Magpie (including one that was
completely missing its tail!), Northern Flicker, Townsend’s Solitaire,
Woodhouse’s Scrub-Jay, and Black-capped Chickadee. About 20 elk were
observed moving north from Bare Slope in the morning. Nine mule deer were
seen on Green Mountain in the afternoon.

Predictions:

========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

That's hilarious Joe. Reminds me of me.
I left my house today at 6:30 a.m. to take an early lunch, returning at 6
p.m. (all counties). Most memorable bird was Blue-winged Teal at
130-something-th and and Buckley (Adams Co). SOB (some other birders).
Returned some voice-mails, replied to some e-mails on my phone. And I
never stopped to eat.

Birders,
I was at Cottonwood Marsh (though there's not a lot of water) around Noon
(yes Joe, 12:00) and saw the following:
1 Tundra Swan (presumably, as it was sleeping)
6 Canvasback
3 Cinnamon Teal
1 Hooded Merg
And:
Shoveler, Green-wing Teal, Bufflehead, RN Duck, Goldeneye, and a few other
dabblers.
20 species in all.
I did see something I had never seen before: A Kingfisher perched (sitting)
on a gravel pile. Wish I'd had my camera.

Subject: [cobirds] MOB, mob, m. ob. or mobs?
It's common to report that a bird was seen by many observers. Even if one
makes a list of all the birders in the group, why mention those
names when "m. ob." will suffice? Who wants their names in the Big Database
that documents that the bird was seen during your "lunch hour,"
as so many rarities are. In fact, for birders, the "lunch hour" is the
interval between 9 AM and 3:30 PM, but that is expandable depending on how
mega
a megararity is. I know a birder who drove to New Mexico and back over
"the lunch hour."

The useful shorthand for a "whole bunch of birders" is some variation of
"m. ob." Or is it "M. Ob."

Also frequently seen are "mob" or "Mob" which seems to mean many, many
observers, a mob, which is larger than a gaggle or an ogle of birders.

As long as the letters "M," "O," and "B" are included, every reader knows
what is meant. Sadly, it is extra sad when a bird is seen nine times daily
by a "mob" or by "m. ob." but you were not there to be part of the mob. Can
you spell "dip?" How sad is that?

Observation start time: 08:00:00
Observation end time: 14:00:00
Total observation time: 6 hours

Official Counter: Mike Fernandez

Observers: Julia Auckland, Karen Fernandez

Visitors:
Occassional Hawkwatcher Julia Auckland stopped by with a friend to help out
for an hour. It was perfect timing as this was during our peak RTHA
activity and the four of us could barely keep up with monitoring the
traffic on the RT highway at the time.


Weather:
Gusty winds all day up to bft 6 (49 km, 30 mi/h), mostly from the west, at
times strong enough to make it difficult to hold the binoculars steady and
keep birds in view. Red-taileds seemed to handle it well, flying NW into
the wind to gain elevation and then dropping east and north to gain
distance. From 12-1 winds shifted east and sky cleared briefly, then
returned to west wind with high and low cloud cover. Late afternoon winds
blew in sparse droplets of rain.

Raptor Observations:
We tried hard to ID raptors as something other than red-taileds, but there
was none of that today. Highlight was six RTHA directly above to the east
and west of ridge varying from two to four in a group at once, plus one
brave local escort. Two RTHA appeared to be migrating but disappeared south
of I-70 at about the saddle; we did not count these two as migrators. The
local Rooney Valley couple (we've named them both Ghandi–for their ability
to peacefully hold still in mid-air) were a spectacle. We observed a total
of 29 Red-tailed Hawks today, including migrators, locals and two with
unconfirmed flight plans. Also saw a local American Kestrel.

Non-raptor Observations:
A herd of eight elk kept an eye on us all day from near the bottom of the
east side of the ridge. Two Mountain Chicadees joined us back and forth
between the platform junipers. List of non-raptor sitings: 2 Woodhouse
(Western) Scrub-Jays, 3 Black-billed Magpies, 1 American Crow, 7 Common
Ravens, 2 Mountain Chickadees, 5 Bushtits, 2 Townsend's Solitaires, 5
American Robins, and 1 Dark-eyed Junco. Reported on eBird.

Predictions:
More wind late Monday, but we're counting on Joyce to stamp passports for
other species. Have all the red-taileds left town? Not likely with ~250
counted in 2016.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] DST and bird feeders
Hi, bird lovers,

We have a bunch of confused birds swirling around the backyard right now. Scott brought inn the feeders and wired up the birdbath (raccoons) at the “usual time”, but for the birds it was an hour early due to DST. Awww. Goldfinches and a robin were walking around on the wire cover of the birdbath and the bushtits came in their usual giant mob aiming for the suet just after Scott had brought it in. Oh my, the guilt.

Subject: [cobirds] They Won't Take Us Dancing, So We Went Birding
To try to forget about the basketball game last night, some members of the
Colorado State Field Ornithologists went out birding at Timnath Reservoir
(Larimer County) today. Although mother nature's wind defense kept our
eBird list (26) from passing Gian Clavell's point total last night (30), we
found a few good birds including three Greater White-fronted Geese, an
early Franklin's Gull, and a weird looking first-cycle Mew Gull. All of
these birds were seen from the peninsula on the north side of the
reservoir. The Mew Gull may have looked weird (it seemed closer to
juvenile plumage than I would expect at this time of year, but the photos
seem to show the mantle different than what I thought I saw) because the
wind did not allow us to get stable views. Unlike the Franklin's Gull, the
Mew Gull was seen before the wind knocked my scope over into the mud.
Overall, Timnath is very full of water and didn't have many waterfowl. The
best duck diversity was along the north shore, and we were surprised to
only see one Common Goldeneye (who flew a couple of laps around the
reservoir).

Good Birding!

Subject: [cobirds] Park County
Greetings All


Yesterday was mostly sunny and windless in Park. I birded from Lake George to Elevenmile Res, then went along Tarryall Creek heading west from Como as well as birding Como and Jefferson


Note that Elevenmile Res is bustling with birds, but Spinney Mountain Res is closed, including entrance road (though not all frozen) - frustrating. Antero Res is now full, but access still zero. Do not be fooled. The northeastern access road had gate open and shiny new signs. It really looked ready to go, but fortunately I stopped I looked at all of the signs (about 6), and one said "area behind sign closed." Still a bit ambiguous, as it did not clearly apply to road (could easily have meant field areas) -- anyway, the southeastern access was well shut.


I don't understand the operations of the CDOW -- both in seeming random and purposeless closures (the signs at locations often differ wildly from website re: dates of access and who has access), and in poor signage (often ambiguous). I'll stop here. The attitudes and organizational skills seem far from those of WDFW (WA Dept Fish and Wildlife).


Anyway.. I suspect Antero might be open this summer, which could be very interesting, indeed. A local thought Spinney might open soon.




So, back to birding. 62 species. The rarest was likely Greater Yellowlegs, with 3 at the se. corner of Elevenmile. Early-ish Williamson's Sapsucker and Western Bluebird just s. of Lake George (lake, not town) were fun as was a N Pygmy-Owl that responded to my endless tooting (to attract chickadees, etc)


Finches were scarce (No Cassin's, few siskins, only 4 Red Crossbills, no grosbeaks), but there was Gray Jay and Am 3 Toed Woodpecker headed w. from Como along Co Rd 50 just a couple miles out of town.


Interestingly, birds came in more aggressively in response to taped calls of Goshawk than pishing and calls of N Pygmy Owl. This was true near L George and near Como. One of the Gray Jays, in <2 minutes (probably <1 minute) was doing a near-perfect imitation of the goshawk recording. That alarmed me!


Good Birding

Subject: [cobirds] looking for a pair of used binoculars for an indigenous Costa Rican bird/culture guide
Dear Cobirders, This is a not a bird sighting, nor is it about a request for money.

My friend Paula Palmer lived in Costa Rica for a number of years, and goes every year. She lived and worked in an indigenous Bribri community. She wrote: My Bribri friend Mauricio Salazar in Costa Rica asked me whether I might be able to bring him a pair of used binoculars for bird watching. Mauricio is the best Bribri culture/nature guide in the Talamanca region, but he has been very ill for the last 6 or 7 years with cancer. He continues to do rounds of chemo, off and on. He told me he would just like to have a pair of binoculars to use for his own pleasure now that he is mostly confined to home. Just wondering if you know anyone who might have an extra pair they are ready to part with? I leave for Costa Rica on March 27. Thanks, Elena, -Paula

Please contact her directly: <paularpalmer...> <mailto:<paularpalmer...>

Thank you in advance for any help. The ABA program that sends binoculars and scopes to Latin America is in a transition period and likely cannot help.

Subject: [cobirds] Convergence of Avian, Lunar and Human Elements
Well tonight was pretty spectacular at the Monte Vista National Wildlife
Refuge. It seems a number of photographers had realized that the moon would
be rising over Blanca Peak at the right moment when thousands of cranes and
geese would be flying past. (There is software now that can take your
location and predict the lunar rising point/direction!) It was an elbow to
elbow event as excited photographers assembled in close quarters.
(Sometimes TOO close to my tripod leg...a little space please!). Some came
from Albuquerque, one from Thailand via Taos, and one from Salt Lake City.
At about 5:30, the moon rose and shutters clicked like raindrops on an
awning. Had to chase the moon as it rose and watched for approaching birds.
Click click click at 7 frames per second. I almost expected to see camera
motor drives start smoking! (Well not really but it was wild). When all was
said and done, I think most everyone captured an image to remember. The
birds flew by the rising moon, with Blanca Peak in the background and nice
softy light on the foreground meadows. It was a spiritually lifting event
no doubt. I will post a few to my zenfolio webpage when I get them
downloaded.

Subject: [cobirds] Birding Around Colorado
Hi Everyone

Today my mom and I birded around Colorado hitting some of the spots that
have been hot lately. Starting with Westerly Creek Park.
At Westerly we found the Harris's Sparrow in about 2 minutes which I know
has been a little hit or miss lately. Also there was a Lincolns sparrow in
the same bush. In the park itself the Brown Thrasher continues along with a
pair of Yellow Rumped Warblers, 2 Cinnamon Teals, and a leucistic American
Wigeon.

At Cherry Creek we started off with an Adult Thayer's Gull and 3 California
Gulls. We then went to the South End( Dam End)where we had a supposed Rock
Wren but later made the easy correction, as the bird was a Carolina Wren
constintaly making its light Trill calls over and over again. And no it
wasn't a Marsh Wren :) Too trilly, not chattery like a Marsh Wren.
We could never find the bird even though we heard it 6-8 times, but
looking for the Wren lead us to find a Says pheobe, American White Pelican,
and a flyover Kildeer along the dam.


We then visited Panama Reservoir where after spending 30 minutes looking
for a vantage point saw 3 Blue Winged teals, 3 pelicans, 18 Norther
Pintails, and two Eared Grebes.

Subject: [cobirds] Blue-winged Teal near Barr Lake, Adams county
At the small lake west of Buckley Rd. at 132nd Avenue there were 4 small teal: 2 male Cinnamon Teal, one male Blue-winged Teal and one female. They were hiding in the reeds at the northeast corner, so the female could not be assigned to a species. The various ducks on this pond are very easily flushed, so best to stay in your car.

Subject: [cobirds] Grandview Cemetery, Fort Collins (Larimer) on 3/10/17
It's a good time of the year (bird turnover and meaningful college basketball games galore) and getting better by the day. We made it thru another February. Lots of spring activity underway.


Yesterday at Grandview, were many highlights, none of them RBA-worthy, but immensely amusing if you are easily amused.


An estimated 45 Cedar Waxwings displayed an assortment of feeding activities. They consumed the flowers of American Elm.


[cid:082b9c60-f59e-4e90-8f4a-efd1b6a3bb3a]


They occasionally engaged in "flycatching" while feeding on flowers. As best I can guess, the target objects of these sallies were brown lacewings.


They consumed European Fruit Lecanium scale insects (both adult females (rusty brown) and nymphs (either white or gray with white margin)) pried from the same small branches where they were getting flowers. I am guessing the lacewings mentioned above were preying on scales, as not too many other insects are available at this time of year except default prey like scales that don't move much and, thus, are continuously vulnerable.


[cid:7f319e28-0bc9-4aa5-831f-7a1e0567e562]



The recent winds, seemingly endless, finally ended and the result was a plethora of juniper berries being shaken to the ground under particularly fruitful female trees. Waxwings, along with dozens of robins, were mostly on the ground feeding on these winter-processed (i.e. softened) berries, but a few were up in the trees getting still-attached fruit.


[cid:255dd276-0a6c-4f39-8de9-f81926e28db8]


The female Great Horned Owl is on the nest in the traditional American Elm site at the west side of Section H. I first noticed her on the nest March 3rd, which if not THE day she started, it is within a day or two. The sticks placed many years ago in the nest crotch by a well-meaning "friend" of the owls are now sufficiently decayed that she can sit in there without being conspicuous. In fact, she is barely visible. When I have checked, her head is only visible when viewing the tree from nw of the nearby intersection looking back se to the tree. As a visual reference, from this vantage, an owl feather currently dangles from a sucker sprout about a foot above the top of her head. The male has been taking up his relaxed watch (think TSA prior to private-parts invasive searches) in the second spruce west of the nest elm.


Other interesting birds were Bushtit (small flock), a few Brown Creepers, one singing Pine Siskin (notably entirely absent this winter prior to today), a few Red-breasted Nuthatches and a Ruby-crowned Kinglet (one of two that has overwintered at Grandview subsisting primarily on overwintering adult hackberry gall-making psyllids extracted from under spruce bark flakes).


The Dark-eyed Juncos are singing, as are House Finches, Eurasian Collared-Doves and Northern Flickers.


The Eastern Screech-Owl present in January hasn't been seen for over a month. I have not seen a crossbill of either type at Grandview for over a year except for one heard-only, possibly imagined, flyover last autumn.

Subject: [cobirds] Black Swan (Cygnus atratus), Weld County, etc.
If I were the most interesting man in the world, I would say:

"I don't go birding in Weld County very often...

...but when I do, I usually see a Colorado lifer."

Thus did I venture this sunny Friday morning, March 10, to an innominate
pond off Colorado Hwy 119 just east of Longmont. And what, pray tell, was I
doing there? Well, on a lark, and, more to the point, on a tip from Elena
Klaver, I went to see a *black swan* she'd discovered a few days earlier.
It was immediately clear to me that I wasn't in Boulder County anymore, for
the businesses in the general vicinity of the stakeout included the
following: Phoenix Weaponry, Longmont Electromagnetic Interference, Smart
Start Ignition Interlock, the City of Longmont Police Department Firing
Range, and Mountain View Fire Rescue. I am not making this up. I was close
enough to Boulder County that I could smell the lattes brewing and incense
burning over in Longmont, but, still.

Anyhow, the bird was there, just where Elena had found it. The best
viewing--and probably the only legal viewing--is from the terminus of Weld
County Road 5, just south of Hwy 119. Park by the gate, have a scope (the
pond is large and somewhat distant), and keep an eye on the black
helicopters...

The record has already been promptly deleted from eBird's public database.
That's messed up. No diss on eBird's hardworking and brilliant Colorado
reviewers, they're just doing their job. But this is one where eBird policy
is out to lunch. Don't get me wrong, I'm a huge fan of--and tireless
advocate for--eBird. But on the matter of known or presumed exotics,
they're just wrong--at least from any credible biological, statistical, or
logical perspective. The swan was there. It was in the environment, cycling
nutrients, transferring energy, and interacting with other organisms, as
real as any Purple Sandpiper or Rufous-collared Sparrow or other wild bird
in Colorado.

Delighted with my find--I mean, Elena's find--I celebrated at a convenience
store in Longmont with a 44-oz. Big Gulp (Mountain Dew - Cherry Coke
cocktail), which, sometime later this year will have a $4.40 tax added to
the cost. Can you say Referendum 2H? Expect me to indulge even more of my
vices in Weld County, once the sugar tax kicks in.

I digress.

Okay, I birded a few spots in Boulder County on the way back down to
Lafayette, with the following results:

1. Boulder Creek crossing at Sandstone Ranch, County Line Road. An early *Say
phoebe* on the Boulder County side of the line.

2. Panama Rez. A distant *swan sp.*, tundra or trumpeter, ecologically
equivalent to the Weld County swan, but judged by eBird to be somehow
different. Sorry. Also 2 early-ish *blue-winged teals,* 4 *mountain
bluebirds,* 7 *northern pintails,* 2 *American white pelicans,* and a
passel of grebes, at least 62 *horned,* 1 *eared,* a couple *pied-billeds,*
and 1 distant bird that I think might have been a red-necked; not sure on
that one, though.

3. Kenosha Road. *Swan geese, graylag geese, mallard x muscovy, Indian
runners,* and more; *Canada geese* and *"northern" mallards* mixed in with
them. Got pix and audio. Will eBird explode?

4. Prince Lake No. 2. Still a lot of *cackling geese* hanging on, plus at
least 10 *pink ring-billed gulls* on the far (west) shore. Two *bald eagles*
in high, soaring courtship flight were impressive.

5. Greenlee Preserve. Another *pink ring-billed gull* and *American
bushtits* gratuitously adding to their Brobdingnagian nest.

Observation start time: 09:00:00

Total observation time: 6 hours

Official Counter: Debbie James

Observers: Barb Banks, Gary Rossmiller, Jim Banks

Visitors:
Various hikers and bike riders, only a handful stopped to chat. One
special guest was Jane Haddock who did Hawk Count back in the late 90's
early 2000's. She plans to be back up on the Ridge to count again.


Weather:
A beautiful, dry, dry day up on the Ridge. There was heavy smog emanating
from the Denver Basin, pushed up to the mountains by prevailing easterly
winds. The ceiling on this smog was about 200 feet, so did not impair
spotting birds. Light breezes all day.

Raptor Observations:
Seven local Red Tail Hawks were spotted. 4 on the east side of the Ridge
and Green Mountain. The other 3 were west over 1-70 and Mother Cabrini.
The migrators were flying very high, having to circle up to get a good wind
current, as Ridge height winds were low, and not accommodating to
low-energy migratory flying.

Non-raptor Observations:
Many, many more birds today than we saw last week. 5 Black billed Magpie;
5 American Robin; 2 House Finch (heard); 2 Northern Flicker; 3 Townsend's
Solitaire; 5 Chickadee (species); 2 Meadowlark; 9 American Crow; 2 Scrub
Jay; 2 Common Raven; 3 Mountain Bluebird; 20 Bushtit. Also one Cottontail
rabbit up by the station.

Predictions:
Tomorrow looks slightly cooler, with a 20% chance of precipitation---we can
only hope.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Yesterday morning I heard, to my surprise, and then saw an early Gray Catbird in the tangle on the east side of the lake where the Trumpeter Swan has been seen this winter. Douglas County side of Chatfield State Park, accessed from Titan Rd S to Wildlife Dr, turn R to small parking area on your left. Trail branches off to left, southernmost lake.

Only thing that made sense about the sighting was perfect 60 degree weather at 9 a.m. Seemed like May out there.

Official Counter: Mitchell Blystone

Observers:

Visitors:
Little traffic on the trails though Pat Connor, JeffCo Open Space and
former Hawk Watch volunteer stopped by to check in and watch the skies for
a bit.


Weather:
The morning began with a slight breeze from the west and near calm sunny
conditions. Eventually the wind came from the east and during the noon
hour it became very strong and swirling at the site. The sun remained out
and temps reached 66F.

Raptor Observations:
The local Red tails were very active all day and even shared an intimate
moment on the power lines to the east. I did observe an unidentified
falcon early in the morning flying near some of the local Red tails but
it's path went straight east until it disappeared on the south side of
Green Mountain. The migrating birds observed came from the Mtn
Morrison/Two Pines area and for the most part were very high up.

Non-raptor Observations:
Blue birds!! Several groups flew right past or right through the platform.
The Scrub Jays were very vocal and busy and some were carrying sticks when
they flew over. Townsend's Solitaires, Magpies, and Chickadees
(Black-capped?) were hanging out as well.

Predictions:
No thoughts on predictions for tomorrow but I would say that between today
and my last day up it seems that when you see one moving through there will
be a couple accompanying bringing up the rear.
========================================================================
Report submitted by Bird Conservancy of the Rockies (<jeff.birek...>)
Dinosaur Ridge information may be found at:
http://www.birdconservancy.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Around noon today, we were able to re-find the Harris's Sparrow first reported by Jason Bidgood, in roughly the same area that he originally found it.
A skulky Brown Thrasher also made a brief appearance, not that there's any other kind...
On Sunday, a bit north on the same trail, we also had an early Lincoln's Sparrow associating with a small flock of juncos. Cheryl Teuton

Subject: [cobirds] Pieplow Field Guide
Cobirders,

My copy of the Peterson Field Guide to Bird Sounds of Eastern North America, written by fellow Colorado birder, Nathan Pieplow, just arrived.

It is a joy to see this book finally in print, and I can see why it took over a decade to prepare. What an outstanding contribution to birding this is! Those of us who have seen Nathan’s articles in Birding, or heard his talks at DFO, or taken his workshops at CFO or WFO, or followed his blog, earbirding.com, know that Nathan has sought to advance the ability to describe birdsong. He, with help from many other experts, has done this admirably. I believe he is developing a birdsong vocabulary. (As we know, much of science is advanced by development of new or standardized terms, helping us to make finer distinctions). You probably already can tell a trill from a warble, but can you differentiate four different kinds of croaks? Did you know that Nathan has suggested certain splits, based upon birdsong alone? Do your eyes glaze over at the sight of a spectrogram? Nathan’s descriptions demystify them, helping us understand features quickly. His classifications will help birders to identify a bird by its song more readily, and learn those songs more quickly. Nathan developed his knowledge through analysis of recordings, many his own, then analyzing them for their components. We don’t need to know how he did this to use his analysis to our advantage.

I learned to recognize birdsong through the audiotapes “Birding by Ear” by Walton and Lawson in 1989 which taught me to group songs. When I went to Costa Rica, for example, I downloaded new songs into those groupings on my iPod. At the worst, I could narrow down an unfamiliar song to a group on my iPod and review the group to pinpoint the songster. Nathan’s methods go much further. The index, for example, lists types of song, and the birds that sing those types. In addition, recordings (5,400 in total) accompany each bird included.

Are you just beginning to learn to recognize birdsong by ear? This will accelerate your learning. Are you an expert who can recognize songs and calls from all species in North America? This book will help you appreciate differences and meanings in an individual’s song

Portrayed is birdsong of 520 eastern birds, most of which also occur in the west, again helping with identification and learning of specific birds. Don’t be put off by the lack of Townsend’s Warbler song. Buy this book to learn how to be a better birder. Remember, experts (not me) identify 90% of the birds by their songs. (I have no financial interest in this book). Check it out on Earbirding.com.

turn right (west) on 44th Avenue. Go one mile west. Look for the
entrance to Prospect Park on your left (South). Meet at 0830 just
inside the park in the lot right next to Prospect Lake.
This is a trip with easy walking and accessible for mobility
impaired individuals. Bring water and a snack; lunch option. Good
trip for novice birders and new members. Register online or contact
leader.

The DFO Field Trip for Sunday, March 12 will be to Cherry Creek SP
Wetlands Loop led by Karen von Saltza (kvonsaltza AT yahoo.com;
303-941-4881). Meet at 0800 at the Prairie Loop lot in Cherry Creek
SP. From either park entrance, follow Lake View Road to the Prairie
Loop that is located at the south rim of the reservoir. State Parks
pass or day pass required.
Day Light Savings Time starts March 12. This half day of walking
passes through most of the important habitats found in the park over a
distance of about 3 miles. Trails could be slippery or muddy, so
dress accordingly. Bring water and snacks; lunch is optional.
Register online or contact leader.

Good Birding,

None.


Weather:
A mild partly cloudy day with temps from 35 to 51 F. Calmer than the gale
force type winds of the past days, but still a steady wind mostly from the
NW around 3 and 4 Bft. through the day.

Raptor Observations:
Possibly a migration catch-up after the recent high winds, with several
migrating Red-tailed plus an adult American Golden Eagle. The time between
10:30 and 11:30 was especially active for both migrating and local
Red-tailed Hawks, with some locals travelling well past I-70 either as
escorts for migrants or on their own, only to return south. The migration
route was almost exclusively along the valley between Mt. Morrison and the
Ridge at various elevations including eye level. Speculation was that this
provided some wind protection or other favorable flight in the NW winds.

Non-raptor Observations:
Also seen were Western Scrub Jay, Black-capped Chickadee, Mountain
Chickadee, Common Raven, American Robin, Townsend's Solitaire.

Predictions:
Possibly similar to today?

Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of
the Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old two-track and quickly turns south onto a trail on the west side of the
ridge. When the trail nears the top of the ridge, turn left, head through
the gate, and walk to the clearly-visible, flat area at the crest of the
ridge.

Subject: [cobirds] Re: Dinosaur Ridge (07 Mar 2017) 2 Raptors
Quick note about the March 7th hawkwatch data:

After discussing, Gary Rossmiller and I have decided to change the
Broad-winged Hawk recorded on yesterday's count to an unknown raptor. This
has been updated on hawkcount.org and ebird.

Thanks,

Very bad pic (full size & crop from same photo), very cool bird, extremely wary. Near house and feeder (on elevated porch), 3/07/17, north-central Larimer Cty, 8100', lodgepole/spruce forest with aspen groves and natural meadows.

Second sighting, was also here 2/26/2017 (no pic), and was heard singing, briefly, 3/4/17.

Subject: [cobirds] American Three-toed WP, Heil Ranch, Boulder Cty, 3/7
This afternoon I headed up to Heil Ranch to search for the Williamson's Sapsucker reported by Kathy Mihm Dunning a few days ago. About 200-300 yards prior to the stone cabin ruins located just shy of the 2 mile marker on the Wapiti Trail, I found a large mixed flock of 3 Downy WP, 3 or 4 Hairy WP, 20+ Pygmy Nuthatches, a few White-breasted, a couple
