Date: 4/24/24 9:50 pm From: Nathan Pieplow <npieplow...> Subject: Re: [cobirds] Mystery dove song at Golden Ponds
Folks,
I do not believe the Longmont mystery bird is a White-tipped Dove. At least
it's not a typical one.
I probably spend 5-10 days in White-tipped Dove's range in an average year.
The candidate sound that people are hearing a resemblance to is what I call
the "Growl Song" of White-tippped Dove. This is much less common than the
regular song and apparently given in courtship situations. (Almost all
North American dove species have some kind of raspy, growling, or trilled
courtship song.)
Here are four examples of White-tipped Dove's Growl Song:
Note the distinctive rhythm of the Growl Song: *short-long,
short-short-short-long*, with every note trilled except the last two (the
second-to-last note is sometimes partly trilled). The last two notes
(short-long without a trill) resemble the species' regular song. Everything
pretty much happens on one pitch, except the long notes are lowest in the
middle.
It's important to note that *in every example of the White-tipped Dove
Growl Song, the rhythm never varies much*. This is universal among doves.
They don't learn their songs, which means their songs don't usually vary
much geographically or between individuals. We can expect all normal
White-tipped Doves to deliver the same Growl Song with more or less the
same rhythm and the same distribution of trilled and non-trilled notes,
just as all White-winged Doves sing "Who cooks for you?" in their Short
Song and "Who cooks for you, Julie? Who, Julie? Who?" in their Long Song.
The Longmont mystery bird does sound like a dove, and I can certainly hear
the resemblance to White-tipped in tone quality, but the rhythm and
distribution of trilled vs. non-trilled notes are way off. Part 1 of the
song appears to be a single long, overslurred trill that almost recalls a
screech-owl trill. Part 2 of the song seems to be a non-trilled 4-note
short-short-short-long pattern, each note higher than the last. Neither
song part lies within the bounds of White-tipped Dove variation. I can't
match it to any dove species I know. My best guess would be a hybrid or an
exotic of some type.
It's definitely a tremendously interesting recording. Kudos to Jamie Simo
for noticing that it was weird and getting audio documentation. People in
the area should keep their ears peeled in case this thing shows up again
and starts singing. I would LOVE to know what is making this song.

Visitors:
We had another great day on the ridge with 47 visitors today including a
birder from England looking for his 7000th life species. Thank you to all
that showed up today and helped spot and keep track of our crazy day, both
on and off our volunteer schedule. I am expecting another busy day
tomorrow.
Weather:
Today was a hot one with scattered clouds but rarely clouds covering the
sun. Winds stayed pretty consistent all day today from the general E
direction. Humidity was low and in the last 2 hours a pretty thick haze
settled into the west valley.
Raptor Observations:
The second I got to the ridge today migration was off with a bang with our
best BW day and overall day this season! We had small kettles of 2-5 BW
moving consistently for the first hour and then they continued to come one
by one for much of the morning, dwindling off throughout the day. At one
point we had 4 BW, 1 RT, and 1 FH all in the same kettle. We did get to
see one BW in the last hour of the day as well. We are also seeing SW
moving throughout the day and expect this to continue. Migration as a whole
is truly in its peak currently and we are loving it!
Local RT activity was high and steady all day with up to 6 seen up at one
time. We continue to see 5 local TV moving around the western ridge. We
also saw the local PG, GE, AK, and CH today.
Non-raptor Observations:
Spring migration has also picked up for passerines as we continue to see
FOY birds, with todays being both WBNU and RBNU. Other passerines seen or
heard today include BTHU, BCCH, WEME, SPTO, WTSW, BARS, VGSW, CORA, and
others. WTSW activity was not as high as it has been in the last few days
but they were still active. It goes without saying that the CORA continue
to be active through the day.
Predictions:
Tomorrow morning will be sunny with winds from the SE. Rain is possible in
the afternoon, potentially kicking off our predicted rainy weekend. As
always I cannot promise anything, but am hopeful for more BW in the
morning.
========================================================================
Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org
Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Date: 4/24/24 6:00 pm From: meredith <meredithmcburney...> Subject: [cobirds] Bird Conservancy of the Rockies - Chatfield Banding Station, 4/24/24
We had a beautiful morning for opening day of 2024 banding at Chatfield. Spring is early - there are bushes flowering a week or more earlier than usual. Towhees and chickadees competing to see who can make the most noise. Pelicans soaring overhead. A Downy Woodpecker hung out at the banding station most of the morning, which was a treat for our 4th grade visitors.
We caught 15 birds which included all the usual first day species:
Black-capped Chickadee 4 new, 1 banded 2019 as an adult, so hatched 2017 or before. House Wren 1 Common Yellowthroat 1 Spotted Towhee 1 Song Sparrow 4 Lincoln's Sparrow 1 White-crowned Sparrow, Gambel's 2
We are banding Tuesday through Sunday (closed Mondays) through May 31. You can register to visit on the weekends through the Denver Audubon website. <https://denveraudubon.org/events/> (The first couple of weekends are sold out, so sign up now if you are interested!)

Hey COBirders,
On a beautiful spring morning at CSR (cool, clear and CALM!), migrants are starting to arrive!
First thing, I banded an FOS House Wren adult - could be arriving to breed, or passing through, then about 9:00
a flock of Audubon’s Yellow-rumped Warblers passed through, working the catkins high in the cottonwoods (alas - uncatchable).
I also banded a dozen sparrows (Song, Lincoln’s, one Mountain White-crown, and lotsa Gambel’s White-crowns). Three recaps from 2022 and 2023, and the wintering white-crowns are about 95% done with molting from juvenile brown to their adult white-colored crowns. They will be leaving soon.
It is just starting to green-up at CSR, - on cottonwoods and golden currant, but hardly any green in the ash trees or coyote willows yet.
Happy Migration,
Steve Brown

Interesting, Jamie! I listened closely to the recording, and can hear a
trilling occur before all three of the calls in the recording.
At this link: https://www.allaboutbirds.org/guide/White-tipped_Dove/sounds,
check out the second recording, which includes a similar trill before each
call. Also on several recordings on Xeno-Canto from birds in Texas, like
this: https://xeno-canto.org/277692
The trill in Jamie's recording sounds too low to resemble anything else I
can think of that trills.
I'm interested to hear what others think of this recording, and the
possibility that Jamie recorded a White-tipped Dove?

Visitors:
We had another great day of visitors on the ridge today with a few in
search of BW and about half of them being successful. As always thank you
to our volunteers and visitors for helping spot birds! Happy 13th Birthday
to our youngest observer, Archer S. Thank you for choosing us to spend your
afternoon with us! We had a total of 38 visitors on the ridge today with
many of them stopping to ask questions and hang out to try their luck at
seeing a migrant. Our volunteer Dave Erickson brought our honorary
observer, Prairie the Bernese Mountain Dog, up for a quick visit today.
Thank you Dave, she is my favorite.
Weather:
Today was a bit cooler than yesterday but we had excellent viewing
conditions again with 50% or higher cloud cover all day. Winds were from
the E in the morning but started to vary in the afternoon. We got drizzled
on for no more than 10 minutes in the afternoon.
Raptor Observations:
The day started out with something I haven’t seen at this site before, a
push of 5 OS back to back to back in about 20-30 minutes. We had one non OS
move between them but other than that it was an OS start to the day.
Migration stayed pretty consistent today with our lowest hour seeing 5
migrants. BW continue to move and had a nice push in the early afternoons.
We also saw a nice little push of SW in the late afternoon. As always we
got to enjoy our “5 o’clock falcon hour” with very close AK coming
one after the other.
Local raptors seen today include BE, GE, RT, TV, SW, and PG.
Non-raptor Observations:
Spring has sprung for our passerines with FOY WEME, BTHU, WTSW, VGSW, BARS,
BBMA, WOSJ, SAPH, CORA and others seen today. We had two groups of AWPE
today, one of 5 and one of 30. The swifts & swallows have been out en masse
dominating the sky for the last few days, confusing us at times with tiny
speedy AK.
Predictions:
Tomorrow will be warmer than today with party cloudy conditions and
variable winds but some SE winds predicted. We are expected to get more
precipitation in the area this weekend. As always, I cannot promise
anything, but I’m hopeful for some more BW and SW tomorrow. Bring your
sun hat and optimistic attitude and we will see you on the ridge!

I was at Golden Ponds in Longmont this morning and in the back corner by the creek I heard an odd dove song. My first thought was that someone was blowing a recorder because it had that quality to it. The Merlin app didn't ping on it, but I did get a recording. I'm not sure if Cobirds will allow the link, but here goes nothing. You can hear it best at 1:49, 2:44, and 3:17: https://drive.google.com/file/d/14hsOg2PM-D2R0AVuDtFw4YdvgUeizcAe/view?usp=sharing
I couldn't locate the bird to see it, but the closest song to this that I could find is White-tipped Dove. Am I crazy? Is this just a weird Mourning Dove or Eurasian Collared-Dove?

Date: 4/23/24 12:25 pm From: Luke Pheneger <phenegerluke...> Subject: [cobirds] Chaetura Swift Help
Hello Everyone,
I would like to start a conversation about Chaetura swift identification in
light of the recent Vaux’s Swift reports from Valco Ponds. I find that this
is an extremely difficult and underrated identification question, and I
would love to hear comments from the community to help clarify my own
thoughts. I also hope this discussion can be an opportunity for everyone to
dig into an ID topic that is rarely studied in colorado!
I recently spent some time observing the swift(s) present at Valco Ponds,
and found myself unable to confidently place the bird in the Vaux’s
category. There are a myriad of factors that go into this difficult ID, and
I think that many of these traits are quite variable. I have listed my
thoughts on each identification trait generally used in Chaetura swift ID
below.
First, per eBird bar charts, Vaux’s Swift should not be considered the
expected swift during the third week of April. Chimney Swift has been
observed in Colorado as early as April 9th, and I have personally heard
them calling on the plains as early as April 23rd. I think it’s important
to note this so that we don’t go into this ID with a potentially biased
judgment.
Secondly, in terms of physical structure, I have read that a consistent
physical difference is that Chimney Swifts typically have longer, pointier
wings, and bulging inner primaries. This creates a pinched look where the
wing meets the body, which is less present in Vaux’s Swift. However, after
digging through many Chaetura photos on eBird, I’ve found that this almost
entirely depends on the angle of the photos. I feel that I can find photos
of both species having both wing shapes depending on what I want to see. If
a bird is pursuing aerial prey, they constantly change their wing shape,
and that distorts with the wing proportions. Additionally, there are also
documented differences in both physical size and flight pattern. I
personally was not able to observe the bird next to any other birds, but a
Vaux’s Swift should be about the size of a swallow, if not slightly
smaller. A chimney Swift should be slightly larger than the surrounding
swallows. If anyone was able to observe the bird in question with swallows,
I would love to hear about it! As for the flight style, Vaux’s are
considerably more bat-like in their flight, while Chimney Swifts have
longer slower strokes. I was not able to personally differentiate those
traits while watching the bird at Valco, but again, I would love to hear if
anyone saw something that they feel strongly indicates one way or the other.
Next, in terms of plumage, I noticed a lot of field notes stating that the
bird was IDd by a paler throat and a paler rump. This has been a purported
field mark for a while, but it is not an absolute trait, but rather a
gradient. Both Chimney Swifts and Vaux’s Swifts have pale throats, and it
is therefore important to look at this field mark in the context of the
entire underparts. Vaux’s swifts have low contrast throats because their
breasts are lighter, while Chimney Swifts actually seem to be the Chaetura
with higher contrast throats. This variability is also present in the
lighter rump trait, where many chimney swifts also show a light rump. These
traits seem to be highly dependent on the light conditions during
observation. I have included some photos of the Valco bird that show
potentially contradictory characteristics (potentially due to the lighting
conditions)
Finally, I think that this ID problem is complicated by the possibility of
multiple birds currently residing at Valco Ponds. Some observers have noted
multiple birds on their checklists. I also believe that there are multiple
birds at Valco Ponds, as many of the characteristics I listed above vary
greatly between photos, differing more than I would expect for a single
individual.
If anyone has any additional photos that are not on eBird, I would also
love to see them! Fantastic work by Chris and Brandon for calling attention
to this bird, and great work by all those who took photographs!
I look forward to hearing your opinions and learning more about this
fascinating ID conundrum!
Best,
Luke Pheneger, Boulder
William Anderson, Erie

Observation start time: 09:00:00
Observation end time: 17:00:00
Total observation time: 8 hours
Official Counter: Emma Riley
Observers: Bill Young, Mike Serruto, Ryan Gannon, Shay Lyons
Visitors:
We had a great crowd up at the ridge this morning with folks in search of
BW and they were not disappointed! While looks at the birds could have been
better, everyone that came out to see them got to see them. As always I
want to thank our volunteers for their help spotting distant birds today.
We had a total of 44 visitors on the ridge today with many of them getting
to see migrants.
Weather:
We had excellent viewing conditions today with cloud cover all day and
partial sun. Winds were from the E in the morning and began to vary in the
late morning. Right around the 1300 hour winds picked up to speeds of 26
mph in gusts, continuing for the rest of the day. Rain could be seen west
of us in the late afternoon but missed us all day.
Raptor Observations:
Today was our biggest Broad-winged Hawk day to date with all but one of
them in the morning. There was an abrupt halt to their migration when the
winds picked up which was interesting to see but disappointing for our
afternoon volunteers. The smaller birds came en masse in the high winds
with AK, SS, and CH coming so close we felt like we could touch them.
Almost all of our birds today were over the west ridge, with the only
overhead/east birds coming in the afternoon high winds.
Local raptors seen today include RT, TV, GE, CH, OS, and AK. 7 TV at once
were seen around Mt Morrison in the afternoon not migrating.
Non-raptor Observations:
Passerine activity was low today, especially in the late afternoon, minus
the WTSW out in unbelievable numbers. We saw SPTO, SAPH, BARS, CORA, and
others today. 2 CORA were seen mobbing the late BE today, and looking
minuscule next to the eagle.
Predictions:
Temperatures are supposed to be lower tomorrow than they were yesterday but
our nice spotting conditions look like they will be sticking around for at
least part of the day. Migration has picked up and we are hopeful for some
more BW and SW tomorrow.

Hi folks,
Thanks to Linda for posting these details, and I wanted to add some
information about Bird Conservancy's banding station at Chico Basin Ranch.
We're planning on continuing to run the station for 5 weeks each spring and
fall.
- The banding station will be open 6 days a week (closed Sundays) from
April 29th through May 31st. The station is open until about 5 hours after
sunrise (weather permitting).
- Visitors are still welcome at the banding station during operating
hours, though registration through Aiken Audubon's system is now required
to access the site.
- We are still working with Ranchlands to host visiting school groups at
the banding station. School groups can register by contacting
<learning...> These visiting school groups, as well as any
on-site Bird Conservancy staff and volunteers, will not count towards
the 20-person daily visitor limit.

Observation start time: 07:45:00
Observation end time: 18:00:00
Total observation time: 10.25 hours
Official Counter: Dustin Kohler
Observers: Audrey Anderson, Emma Riley, Mike Kohler, Susie Kohler
Visitors:
We had 53 visitors to the ridge today including my parents who came out to
visit from Missouri. Thank you guys again for helping out all day today.
Weather:
Today started as a very foggy, but otherwise sunny day before turning into
a blue sky full of sunshine. Towards the end of the day, it became more
partly cloudy.
The wind was gusty and out of the Southeast throughout the day.
Raptor Observations:
Our migrants started fairly low to the east or straight up, but then got
higher and either remained straight up or were to the west.
We had 16 of our 19 species migrate, but saw 17 out of our 19 throughout
the day, only missing Rough-legged and Ferruginous Hawks.
Almost all of our accipiters migrating had a full crop, at least the closer
ones.
Our first Bald Eagle was missing a secondary flight feather, and the
juvenile Bald Eagle looked very raggedy in terms of missing feathers.
One of our migrating Red-tailed Hawks had a white tail, and it's chest was
fairly white with a dark belly band. This bird was possibly a White-morph
Harlan's, but I am not sure.
Our unknown Falcon was probably a Merlin, but too far away to be sure. One
of the unknown Buteos was probably a Swainson's Hawk. The other unknown
Buteo and Accipiter were too far away to guess which member of their genus
they were.
In local/ non-migrating news, we had our usual Red-tailed Hawks, but we
also had a local Golden Eagle, Swainson's Hawk, Bald Eagle, Cooper's Hawk,
Peregrine (seen twice), and two different Northern Harriers.
Non-raptor Observations:
We had 3 Double-crested Cormorants and about 53 Franklin's Gulls migrating
a few hours apart. We also had White-throated Swifts, and at least 3
different species (Tree, Barn, Violet-green) of Swallows migrating
throughout the day.
Other passerines included: Broad-tailed Hummingbirds, Red-breasted
Nuthatch, Black-billed Magpie, Bushtits, Dark-eyed Juncos, Spotted Towhee,
Western Meadowlark, Northern Flicker, and a Rock Wren.
Predictions:
Tomorrow looks like a warm, partly cloudy day with winds out of the
Northwest. A good sky for viewing migrants, but join Emma up on the ridge
to see how that Northwestern wind affects the migrants.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org
Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.

Took a quick run around southwest Weld Co. this afternoon (Sun., 21 Apr.'24) to check for shorebirds. Most every spot had very high water as expected, but needed to scratch that itch just to be sure. While shorebirding was thin, there are always birds to find with the most fun coming at the end of the day with a large flock (38) of MARBLED GODWITs along with five (5) WILLETs on the north shore of Union Reservoir (Weld Co.). Other highlights included several first-of-year species for me with FRANKLIN'S GULLs and a nice FORSTER'S TERN at Prospect Reservoir (Weld Co.), Willets at three different locations, and the always welcome return of SWAINSON'S HAWKs in many spots.
While Union is also high, there is a decent shoreline on the north side so still worth checking - the best shorebird habitat I ran into today. With the Long-billed Curlews Susan just reported at the Arsenal, it's time to get out and do some shorebirding of your own.
Good Birding,
Doug

I found a group of 14 Long-billed Curlews TODAY at Rocky Mountain Arsenal ONLY after someone posted a detailed description in his eBird list as to where he saw them (Thanks Ryan!).

All,
Apparently I wasn't very clear, as questions are rolling in.
The cost is *$15/person/day,* as it's been for years. There is no discount
for groups, as there has been in the past.
A group is meant to be for an organization, like DFO or Audubon
chapters, with 10-12 attendees. We may consider slightly smaller groups,
but it will depend on how busy it gets for our registration team, since all
of us work.
Please do let me know if anything else is unclear.

Birders,
I found a Brown Pelican roosting on Dinosaur Island on the north side of John Martin Reservoir this morning. It was with about 20 American White Pelicans. Dinosaur Island is about midway between the the west and east entrances to the north side of the reservoir, and is about 4 miles west of the dam.
Photos will be posted later.

Observation start time: 09:45:00

Total observation time: 2.75 hours
Official Counter: Dustin Kohler
Observers:
Visitors:
We surprisingly had 13 people visit the ridge today. In addition, a dog ran
up and tried to steal my sandwich, but I was cold and hungry and did not
share.
Weather:
Snows prevented us from getting up as early as usual, but there was a break
in the precipitation. After a few hours, the snow picked back up, the fog
rolled in, and the combination would have made visibility near zero km. At
that point, I canceled the rest of the count.
Raptor Observations:
With bad weather the last 3 days, migrants seemed to be waiting for a lull
in the snow to make a break north. All of our migrants were low either
above me or to the east.
We had a dark morph Broadwing Hawk all by himself, and not long after we
had an intermediate morph Swainson's Hawk.
Our Peregrines, and our other migrants, were flapping constantly fighting
that northern wind.
We had local red-tails, a Cooper's, two Turkey Vulture, an Osprey flying
south, and a local kestrel.
This local male Kestrel was my primary observer today he chased a lot of
other Kestrels out of town, he screamed at the Harrier flying past, but was
strangely quiet during the peregrines passing by. This kestrel also dove
under a bush as a probable sparrow flew out the other side.
Non-raptor Observations:
We had another Great Blue Heron migrate. For the second day in a row, the
highest bird I saw all day was a Great Blue Heron flying straight North
with no deviation.
Passerine birds were much more active today than the last couple of days as
well. I saw some Tree Swallows, a Rock Wren, Dark-eyed Juncos, Western
Meadowlarks, American Robins, Mountain Bluebirds, Black-billed Magpies,
Spotted Towhees, and probably others that I didn't write down.
Predictions:
Tomorrow looks like a warm and cloudless sky with winds from the East/
Southeast. I expect a surge of migrants who were unable to migrate during
the last 4-6 days of bad weather. Bring a neck pillow and fresh eyes
because I expect these migrants high and fast.

the best of the situation and appreciate your patience as we comply with
the new lease requirements.
- *Visitation in 2024 will be allowed ONLY:* *April 29 – June 2, and
Sept 2 - Oct 6*. The ranch will be closed to birders the remainder of
the year.
- Birders will need to register and pay in advance.
- The fee is $15/person. All proceeds will go towards maintaining access
to Chico Basin Ranch for birding.
- Registration for each day opens seven days in advance. For example,
registration for April 29th opens on April 22nd @ 7:00 am.
- Visitation will be capped at 20 birders/day, from 7 a.m. to 1 p.m.,
and access will be limited to the banding station, the HQ pond area (avoid
birding inside the HQ gate) and Rose Pond.
- Groups interested in making a reservation should reach out to
<chicoregistration...>
- All sales are final unless birding is closed at Chico due to muddy
road conditions (see below).
- In the event roads are impassable due to muddy conditions, we will
notify registrants as early as possible that birding is closed for the day
and refunds will be issued.
Please comply with these requirements. Infringements could cause Aiken to
lose its lease.

Date: 4/19/24 10:16 pm From: Thomas Heinrich <teheinrich...> Subject: [cobirds] Colorado Combined Yard List now on Google Sheets
Greetings COBirders and WSBN birders,
I'm happy to share the news that the CO Combined Yard List is now up on
Google Sheets and accessible to all via the link below. A huge thanks to
all who have contributed and made this such an interesting and fun
collaborative project, and especially to Bryan Guarente for his help in
getting this list up and running on Google Sheets.
*Current statistics:*
400 Species
100+ Contributors
30 Counties represented
3200 Total ticks
I would like to share a few thoughts about the list for clarity in terms of
its goals and what expectations we might have for it.
This list is a collective effort to discover and document how many of the
species on Colorado's official state bird list have been observed,
identified, and recorded from a yard. It highlights the incredible
diversity of yard habitats in Colorado, our remarkable breadth of coverage
of Colorado's avian species, and the value of birding in the ultimate of
local patches, our yards. I hope this list will continue to grow, be an
interesting resource, and be a fun way of connecting with other birders
across the state.
One of the main goals is to reflect the communal effort by ensuring that
everyone's contribution is in some way represented and recognized. As much
thought and care as there was put into the matching of species and viewer
(method outlined below), it wasn't possible to pair everyone with each of
our favorite, or most memorable species. The answer to this is the
Additional Sightings feature in Column H, which gives the option of adding
one's name and sighting to species that are personally meaningful.
You'll notice the absence of dates on the list. This is something Bryan and
I debated about, and eventually decided not to include due to various
challenges and considerations. One challenge is that many of us keep
yardlists without dates of sightings, or just general "Summer of '73" kind
of notes. If there is enough interest in adding this data set, we could add
an editable column for it.
The current list total of 400 species reflects the uncertain status of two
species: Tundra Swan and Glossy Ibis. Both species required leaving the
yard to confirm the ID, something that would be potentially permitted under
Big Sit rules, but perhaps not acceptable under the most inclusive yard
listing rules. My initial response was to include them. But then I had
second thoughts. Perhaps it would be best to leave them off the list,
unless there is overwhelming support to include them.
While there is no formal review (a la eBird or CBRC), the intent is to be
as accurate and pure as possible. As new species are added to the list, it
would be ideal, especially for rare species, for contributors to include a
link to an eBird or CBRC report.
It's worth mentioning that this list is neither intended nor set up to be a
database for complete yard lists.
**If you happen to notice a species with "Viewer" listed as Anonymous that
you believe is actually your sighting, and you would like to have your name
listed, please let me know and I will make the changes. This would really
only apply to sightings of species sourced from CBRC and eBird reports.
**If you ticked off a species on Bryan Guarente's Google sheet, but don't
see your name listed here, and would like your sighting to be included,
please consider using the Additional Sightings feature in Column H
(instructions for data entry below).
**If there are any first state record sightings on this list that happen
not to be attributed to the original viewer, please let me know. It would
be nice for the original viewer to receive the recognition.
*A Brief Overview:*
There are three sheets:
1) The list in Taxonomic Order
2) The list in Alphabetical Order
3) A Needs List in both Taxonomic and Alphabetical Order
You can navigate from one to the other by clicking on the tabs at the
bottom margin.
The Taxonomic List is set up so that data may be entered for new species
(the blank cells in Columns D-G). If you have any species to add to the
list, please feel free to enter the information in the
appropriate cells. It would be great to have complete information on each
species (Name, City, County) rather than just a tick. Links to eBird
reports and/or photos would be terrific, especially for the rarer species.
If you would like to remain anonymous that's totally fine, of course. I
would just ask you to consider sharing your sighting with me directly via
email (I will not share any names), just to have some way to verify that
it's an actual sighting (and not bot generated 🙂).
Data that's already entered in Columns A-G is protected. Please let me know
if you see any errors, misspellings, etc in the data already entered. I'll
be happy to make corrections and edits.
***Column H: **Additional Sightings***
Detailed instructions (with screenshots) on how to enter data to come in a
separate email, but here is a not-so-brief description of how to enter
additional sightings.
Notice that each cell in Column H (for species currently listed/ticked) has
a small downward facing arrow along the right margin. Clicking on this
arrow reveals a dropdown list. I've set up several as examples.
1) Click on the small downward-facing arrow. This will reveal a short list
of names & counties, or "Option 1", "Option 2", or a combination of the
two. Below this, in the bottom right corner, is a small pencil symbol
(otherwise known as the "Edit button").
2) Click on the pencil symbol. This will open a sidebar along the right
side of the browser window with the heading "Data validation rules." From
top to bottom, you will see "Apply to Range" & "Criteria" and corresponding
cells. Ignore those, no changes necessary. Below that you will see cells
that contain "Option 1" or "Option 2". If both Option 1 and Option 2 boxes
have been filled out with other observations, you may click on the box that
reads "Add another item" in green text.
3) Click on the first available cell, delete the text that says "Option 1"
or "Option 2", and replace it with your name and county (example: Thomas
Heinrich, Boulder).
4) Click on the green "Done" button at the very bottom of the sidebar. A
pop-up window will appear, which will ask* "Apply to all? There are ###
other dropdowns with the same properties, do you want to make changes to
all of them?"*
5) Be sure to click on the "Just this instance" button only please 🙏,
otherwise potential chaos. If you accidentally click on "Apply to all", you
can undo the mistake by pressing the Command and Z keys simultaneously.
6) After clicking "Just this instance", you'll notice that the cell still
appears blank. Click on the small arrow one more time. This will reveal the
dropdown box again, this time including your name & county. Click on your
name & county. The cell will now list your entry, and you're done.
Note that this dropdown feature allows one to toggle between the various
additional sightings for each species. Anna's Hummingbird, for example, has
been seen in five yards. The Primary viewer is listed as Bill Schmoker,
with additional sightings from Rachel H, Tina J, David S, and Brad B. At
the moment, Rachel H, Larimer is displayed in Column H. But Tina, David, or
Brad might like to have their name appearing in that cell at some point,
and use the dropdown feature to select their entry.
*Links to Colorado Bird Records Committee or eBird Reports (Column I)*
An option for those wishing to share a link to a CBRC or eBird report of a
personal sighting. Please provide links only to sightings of your own, out
of respect for others' privacy or desire to remain anonymous. At the
moment, the list is set up with space for only one link per species. (This
could be adjusted if there's interest in having more than one link per
species.)
*Links to Photos (Column J)*
An option for those wishing to share a link to a photo of a personal
sighting. I've entered one for a Northern Pygmy Owl from my yard as an
example. This is using a hyperlink that, when clicked on, will take you
directly to the photo. As with Column I, there's only space for one link
per species at the moment. (This could be adjusted if there's interest in
having more than one link per species.)
*The Alphabetical & Needs Lists *
These sheets are protected entirely, so it is not possible to edit or add
data to these sheets. At the moment, because these pages are not linked to
the Taxonomic List, data entered in the Taxon List does not automatically
appear in the Alpha List (or disappear in the Needs Lists). For now, I will
manually update the Alpha and Needs list, and hope to get the lists linked
eventually.
*Sources:*
Posts to COBirds
Email sent directly
CBRC reports
eBird reports
*Steps in pairing Species with Viewers:*
1) Recorded unique sightings as they came in (the easy part)
2) Took note of favorite, rare, and memorable species as shared by each
contributor
3) Matched each contributor with three species, prioritizing favorite,
rare, and memorable species
4) Second round, upped the species per contributor to five
5) Third round, upped the species per contributor to seven, where possible
6) Distributed the remaining species
Best wishes for a fruitful Spring migration, and happy yard birding!

Birders continued to see the Vaux's Swift off and on all day along the Arkansas River, from east of Juniper Road below Pueblo Reservoir dam east all the way to the Pueblo West Gravel Pit area. Where ever the big flocks of swallows are, seems to be where the one Vaux's Swift is. Birders with good cameras, should still attempt to get photos, since I don't think anyone has had much success getting a photo that shows the pale rump and pale throat. I think now nearly 20 birders have seen the bird, so hopefully everyone will submit their descriptions to the Colorado Birds Records Committee. I think before yesterday, only a handful of people had seen this species in Colorado. Hopefully it will be found again tomorrow and many more people can see it.

Observation start time: 08:00:00
Observation end time: 11:15:00
Total observation time: 3.25 hours
Official Counter: Dustin Kohler
Observers: Cindi Inklebarger, Ed Forlong, Joyce Michael
Visitors:
We surprisingly had 9 visitors to the ridge today. I will never
underestimate the people of Colorado's willpower for running in bad
weather.
Thank you to my helpers today, even with their Denver Field Ornithology
field trip canceled, they still braved the elements to be up with me most
of the day.
Weather:
Today was pretty cold and snowy. When I first got up to the ridge we were
pretty socked in up there in the clouds. After a half hour or so the clouds
lifted slightly. I was snowed on just about the entire time, but visibility
was way better than I was expecting. Around 11 MST (12 MDT) the snow and
the wind picked up. With snow to continue the rest of the day I called the
count.
Raptor Observations:
All of our migrants were barely above eye level to the east of us. This was
where visibility was the best, and the wind could help them migrate.
We had a local kestrel that headed North along the west of us, turned
around at the break in the ridge where Highway 70 goes through, and started
hunting over Green Mountain.
We also had 2 local/ non-migratory Sharp-shinned Hawks. Both did the same
thing low on our east side, heading straight South, and heading to some
bigger juniper and pine trees assumably to wait out the storm.
Non-raptor Observations:
We had a migrating Great Blue Heron, at least it headed North with a
purpose and was the highest bird I saw all day.
Passerine activity overall was more active than the last couple of days. We
heard/ saw Western Meadowlarks, Mountain Bluebirds, Spotted Towhees,
Dark-eyed Juncos, Rock Wren, and a few others that I didn't write down and
have since forgotten.
Predictions:
From now until 9am tomorrow there will be 4-10 inches of snow at the site.
Afterwards looks to be about a 4 hour gap before mixed precipitation after
that. Tomorrow's count might be delayed and end early, but I'll try and get
up for the middle part unless the roads are bad tomorrow. I don't expect
much to migrate, but I didn't today either and still got 8 migrants in the
snow.

Report submitted by Official Counter (<j.f.peters58...>)
Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org
Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Observation start time: 08:30:00
Observation end time: 10:30:00
Total observation time: 2 hours
Official Counter: Dustin Kohler
Observers: Emma Riley
Visitors:
We surprisingly had one visitor to the ridge today. This lady was running
and stopped to wave before continuing her run. On a day with freezing rain/
snow making icicles form on my hat, she counts as a visitor.
Weather:
Today was a delayed start because of the low clouds and rain/snow. While I
was up there the clouds cleared slightly, but the snow was ever persistent.
I stayed up there for about 2 hours before heading down, due to being
swallowed by the clouds. We waited nearby for a couple of hours, but the
end of the precipitation kept getting pushed back. We finally decided to
end the count as the weather kept getting pushed back, and migrants
probably won't be leaving today.
Raptor Observations:
I only saw two raptors all day today, and both were on my drive home. There
was a Red-tailed Hawk in a tree, and a Swainson's Hawk on a wire, both of
which were puffed up and did not look like they were going anywhere anytime
soon.
Non-raptor Observations:
There was a brief 15-minute period without snow, and in that period I saw a
Say's Phoebe, 2 Dark-eyed Juncos, and a Northern Flicker.
Flying through the clouds was a Common Raven. I never saw it, but I heard
it calling in a very ominous way.
Predictions:
Tomorrow looks like a partly cloudy day that turns into a rainy/snowy day.
Around 2 MST (3 MDT) it should start raining before turning to snow.
I plan on being up there in the morning and we will see how the weather
changes throughout the day.

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.

Date: 4/18/24 2:59 pm From: Brandon <flammowl17...> Subject: [cobirds] VAUX'S SWIFT -- Pueblo April 18
Chris Knight discovered a Vaux's Swift along the Arkansas River, near and west of Valco Ponds parking lot in Pueblo, with a mass of swallows (six species) around 12:25pm today. I was able to get to the area, and was able to find it. The bird moved back and forth over the Arkansas River, from Valco Ponds parking lot, west to the footbridge, that goes from Snakeskin Picnic Area into the Rock Canyon Swim Beach. A few other birders that were nearby, we able to see it. Last saw it at 2:48pm, just West of Valco Ponds parking lot. The swift had very pale rump and light throated. There's cloudy weather forecasted for tomorrow, so there should be lots of swallows around, so hopefully the swift will hang around, though never know of course.

Chris Ray, scientific advisor for the Colorado Pika Project, is the guest
speaker for the April meeting of the Boulder County Audubon Society. Her
talk is titled *A Tale of Two Pikas: from dueling subspecies to dueling
visions of the future for an alpine icon.*
Join us on Tuesday, April 23 (in-person and Zoom) for Chris’s presentation,
which will show the pika from many angles (and mostly in pictures rather
than graphs) to celebrate the diversity and perfection of one of the many
species that might soon become too rare to really study.
Chris has a PhD in population biology and is a scientist with The Institute
for Bird Populations in California and also the Institute of Arctic and
Alpine Research at CU Boulder.
Tuesday, April 23, 7:15 – 8:45 pm, at the Unitarian Universalist Church of
Boulder (5001 Pennsylvania Ave).

Date: 4/18/24 6:39 am From: Patricia Cullen <hathcockcolorado...> Subject: [cobirds] Reactions to new eBird displays and formats
Hello Colorado Birders,
I am just getting used to the new way of showing data in eBird and enjoying the new information. I like that there is a new focus on monthly findings, the top 100 is gone, although you can see the top ten birders for lists and species, and that the number of checklists and species community targets and trip reports are now highlighted in various windows of explore. For instance if you explore a county you can see the latest trip reports submitted.
E.J. Raynor shared with the Larimer chat group that "Community Targets" means species that have not been reported for this month but are most likely to be found based on past years of eBirding in the region.
Any reactions to these changes?

Visitors:
Thank you to all the volunteers that came out today to help spot birds and
practice patience. We had a visitor from Texas today, Nancy, come spend a
few hours with us and she was able to get some great looks at the local GE.
We had another visitor this morning stay for a few hours and bird and I
didn’t catch her name, so my apologies! In the afternoon a local hiker
Tim hung out with us for a few hours and marveled over the diversity in
species we see. All in all we had a total of 14 visitors today, a slow day
on the ridge.
Weather:
Winds were variable all day in both direction and speed. Cloud cover was
consistent today which made spotting high birds relatively easy. All in all
it was a beautiful day on the ridge!
Raptor Observations:
This mornings migration was slower than I had hoped but picked up in the
afternoon, a pattern that seems to be occurring this year more than it has
in the last few years. It was a slow migration day but we had an incredible
amount of diversity with 7 species of migrants.
Local raptor activity was high today with the local GE stealing the show.
Three GE of all various ages (adult, immature, and SA) were seen
consistently all morning. We also saw local RT, CH, AK, and PG today.
Non-raptor Observations:
Passerine activity seemed low today but we still heard and/or saw the usual
suspects including SPTO, ROWR, WOSJ, BBMA, and CORA. We also saw a
centipede on the ridge today, which is the first time I’ve seen one up
here!
Predictions:
Snow/rain is predicted tonight into tomorrow morning. This may slow birds
down in the morning but I’m hopeful that the afternoon push will be nice
with a predicted east wind. I’d bring an extra layer, temperatures will
be much lower than they have been the last few days.

I’m driving north on Indiana Street just north of 72 nd Avenue and west of Standley Lake.
Three male Lark Buntings just flew right in front of my car! No way to take a picture, lots of traffic, but no doubt as to identification.
Very windy.

Visitors:
We had 24 visitors to the ridge today including a 1 or 2-year-old (I don't
know baby ages) who was telling us what sounds different birds make.
Weather:
Today started with a sunny day and turned to an overcast one as the day
went on. The wind was strong and only got stronger as the day went on. A
persistent haze stayed all day in the distance affecting our distant
visibility. The count was ended an hour early due to winds exceeding 35
mph.
Raptor Observations:
We had a slow, but steady migration for the first two hours, but then had a
long period of no migrants. Towards the end of the day, a few migrants
fought through the wind to move on to the north.
Our two Sharp-shinned flew by together. One was larger than the other,
potentially male and female, and the larger one had a full crop.
Today we had three local Bald Eagles, all adults. One of them was being
harassed by a Red-tailed Hawk.
We had another Red-tailed hawk carrying either a snake or nesting material.
With how stiff it was flying I would assume nesting material. This thought
is also supported because both of the nests I have seen in the area were
destroyed in the 100 mph wind last weekend.
Non-raptor Observations:
Before the wind got super strong we had a rock wren on our platform, a
flock of about 40 Franklins gulls migrating closely, and 6 American White
Pelicans.
When the wind picked up we saw a tree swallow, and a lot (or the same ones
many times) White-throated Swifts.
Predictions:
Tomorrow looks to be another windy day. A shortened or canceled count is
possible.

Date: 4/15/24 3:38 pm From: DAVID A LEATHERMAN <daleatherman...> Subject: [cobirds] Mother Nature Giveth, Mother Nature Taketh Away
Today was my first 2024 survey of the western Pawnee National Grasslands to monitor shrike impaling.
Imagine you are a shrike in the late 1800s having to impale your prey on stiff plant stubs, yucca fronds and in the branch crotches of trees. Suddenly the whole world comes your direction with the invention of barbed wire. You now have options, trillions of them. But everything is subject to change and today was a good example. Apparently, the summer rains of 2023 combined with the ferocious winds of last week packed Russian thistle stems (aka "tumbleweed") against hundreds of miles of fence such that the wire is mostly unusable for shrike impaling. A manager at the Central Plains Experimental Range told me besides fences being packed to the breaking point, they estimate 9 miles of fenced pasture with at least one of the four strands (usually the top one) pulled from posts and in need of repair.
Most loggerhead shrikes are migratory. When I was in the Lamar area last week they were mostly back on territory. Over the years I have come to recognize the plant and animal phenology of the southeastern plains is about 7-10 days different from the northeastern plains. Spring springs earlier in the southeast. Fall falls earlier in the northeast. Male shrikes usually arrive in habitat suitable for nesting before the females. One of the major reason newly-arrived males impale in to attract mates. What I saw today makes me wonder how the shrikes will cope. Will they move (far away if necessary) to areas without tumbleweed-packed fences? Will they revert to "old school" methodology? Will they wait a while to nest in the hopes wind unpacks the fences the same way it packed them?
I remember the late Dr. Paul Opler discovering during Breeding Bird Atlas 1 that a subset of Red-winged Blackbirds on the Pawnee nest in tumbleweed-packed fence habitat. They should do well this year.
All the above said, I did find about 17 objects on barbed wire today (I would have expected 100 or more given the date). These included usual items like redshank and Arphia grasshoppers, black field crickets (Gryllus sp.) and a couple lesser earless lizards. Notable were an unrecognizable rodent, the back half of a vole (Microtus sp.), and (drumroll) the first bumble bee I've ever seen impaled (probably Bombus huntii).
[A bee on a wire Description automatically generated]
The Pawnee is very dry. While shrikes were the mission, I did find good numbers of both Thick-billed and Chestnut-collared Longspurs, a few Vesper Sparrows, no Grasshopper or Cassin's Sparrows, no raptors except for two kestrels and one Northern Harrier.

We had 83 visitors to the ridge today. Including my boss and her family! It
was very nice getting to meet everyone.
We had a family local to Denver area speaking to each other in Russian.
They seemed interested in the birds flying past.
We also had a couple visitors that are living in Denver, but are from
Michigan. They used to visit the Michigan Hawk Watch and were fascinated by
our ridge as well.
We also had the pleasure of hosting the Nature Keeper's Youth Group. These
kids were great spotters, helped me take weather data, and seemed to have a
competition for who could spot the most birds.

Weather:
A relatively cloudless day full of sunshine. The fairly strong southern
wind kept it from being unbearably hot. Good conditions for migrants.
Raptor Observations:
Today's migrants were high, but not as high as I was expecting with a
strong southern wind and lots of thermals. These migrants were above us and
to the west primarily, but there was more eastern activity than the last
couple days.
We had a migrating Cooper's hawk dive at a migrating kestrel. The kestrel
just dodged quickly like a bull-fighter, and then they both kept going
north.
Our largest kettle was 6 Turkey Vultures.
One of our Swainson's hawks was an intermediate dark morph adult with a
dark chest and an even darker bib.
Our Goshawk was another immature with an almost too large looking tail.
This bird was much bigger than the Cooper's that went through the same
flight path a few minutes later.
Our unknown falcon was at the edge of the horizon, moving fast, and
disappearing and reappearing rapidly. The pointed wing was the only mark we
could get. Based off of other activity it was probably a kestrel, but we
couldn't even get size based off the rapid changes in its visibility.
Other than our acrobatic local Red-tailed Hawks, we had two local (south
moving) Northern Harriers, one juvenile Golden Eagle, one adult Golden
Eagle, one Swainson's, and two American Kestrels including one female that
was heard calling in the last 5 minutes of the day.
Non-raptor Observations:
We had a good amount of swallows today and I think most of them were
Northern Rough-winged Swallows. There were also some White-throated Swifts,
a few Eurasian Collared Doves, and a very curious White-breasted Nuthatch.
Predictions:
Tomorrow appears to start warm and sunny and shift to rainy and windy in
the afternoon. A partial count is likely tomorrow, but the morning should
be full of migrants. I look forward to seeing you on the ridge tomorrow,
rain jacket in hand.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org
Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.

Observers: Ajit Antony, Boulder Group, DFO Field trip, Liza Antony,
Lori Morton, Shelley Conger, Zach Haag
Visitors:
We had 58 visitors to the ridge today including John Dwyer a member of DFO
who hasn't been to the ridge in many years. We also had a group from
Boulder led by Tim Meehan. The other members of this group were Roger Fong,
Tori Bovish, and Josh Tacey. There was also a mother-daughter group of
Linda Farrell and Reese Erwin who visited the same amount of time as the
Boulder Group.
Ajit and his wife Liza led a DFO group up as well to help us out. I'm sorry
I didn't get the chance to write all of their names down, but there were 16
observers to start the day today.
Weather:
Today was partly cloudy all day today with more clouds in the afternoon.
The wind was gusty turning from a NW headwind to a SE tailwind.
Raptor Observations:
Before we arrived at the ridge there was the Boulder group already up there
and they had a list of birds they have seen: 3 sharp-shinned, 4 Turkey
Vulture, 4 Osprey, 10 Kestrel, 7 Red-tailed, 1 Swainson's, 3 Cooper's, an
unknown accipiter, and an unknown raptor. Most of these birds probably
migrated, but I don't think they all did, especially the red-tailed since
they have less experience with our local red-tails.
For the most part our raptors were high and to the west, but in classic
dinosaur ridge fashion there were still plenty to the east as well.
Two of our adult male kestrels were holding mice as they were migrating
overhead. One of our osprey's had a fish.
One of our migrating Merlin, with uniform wings and a white chest, was very
far away and attacked a migrating kestrel.
We had a local Cooper's, Kestrel, a merlin (attacking a turkey vulture),
one adult Bald Eagle, and one juvenile Bald Eagle in addition to our usual
casts of Red-tails.
We had two red-tailed hawks grasp talons and free fall for several hundred
feet before releasing. One of the two got immediately chased by another
red-tail and was chased to another red-tail. It seemed like the spiraling
two red-tails were not a pair, and each of their mates were nearby.
Non-raptor Observations:
Lots of White-throated Swifts today flying high, there was a group of
around 30. We also saw a few swallows, a double-crested cormorant, some
elk, a balloon, and a few leaves high in the sky.
Predictions:
Tomorrow looks to be a warm day with wind coming from the South. In a not
very cloudy sky, our migrants should be very high up. It is another chance
to bring your neck pillow and spot very high-up dots in the sky, but hey,
it beats working in an office.

Today a Black-and-white Warbler was near my Ken Carylt home, in association with the season's first yellow-rumped Warblers that I have seen in my area. Montane birds have a presence lately., Small parties of Evening Grosbeaks have been regular at Ken Caryl over the last few weeks, mostly on the move. And Cassin's Finch and Red Crossbills, too. Yesterday I had my first-of-season Chipping Sparrow and Broad-tailed Hummer here.

The Yellow-bellied Sapsucker seems to like our tree. This morning he has come back to the yard for a short visit for the 3rd day in a row. Very skittish. Up high in the tree, usually. I’m not sure where he is (most of the time) when he is not in the yard as there are several large trees in the extensive green belt behind the fence. Near Alta Vista Park, Buckley and Olathe Way., Aurora. In case someone might be interested it trying to find him. I will attach photos from this morning.

Visitors:
We had 31 visitors to the ridge today. We also had a Dave Hill lead Denver
Field Ornithologists field trip to the ridge today. Thank you Dave Hill,
Lorissa AvgoRay, John Whitiker, Kent Bagley, Roger Spoulding, and Janice
Arey for coming out today, and I am sorry if I spelled any of your names
wrong.
Weather:
Today was a bright sunshiney day with barely any clouds until about 1500
MST. Then it shifted to a partly cloudy sky about 1530 MST. Today was a
scorcher, especially on the western side of the ridge because that side was
hidden from the Southeastern wind.
Raptor Observations:
As soon as I got to the top of the ridge this morning a sharp-shinned hawk
flew by, so I started the count early. Our migrants in the morning were
everywhere, but in the afternoon most of our birds were high until the sky
became more overcast lowering the migrants for us. In the last 2 hours, we
had some falcon time with, 27 falcons with all 4 of our target falcon
species.
In a crazy 20-30 minute period we had a Merlin, 7 kestrels, a prairie
falcon, 2 peregrine falcons, a red-tailed hawk, and an immature goshawk all
migrating.
The three large falcons were roughly 2 miles away and all in the air at the
same time. The two peregrines were flying together and seemed to be a
uniform dark color. The prairie falcon appeared to have white on its wings
and a darker core because of the darker armpits I assume.
Three Merlin were far away constantly flapping with their longer and more
pointed wing compared to an American Kestrel. The others were right over
our heads.
The American Goshawk was a Juvenile that was close enough to see the wavy
tail stripes! Very thick tail base (where it meets the body) and a heavily/
messy streaked chest. Heavy flapping in the lack of wind at the time.
Our unknown accipiters were right next to each other. One was much bigger,
a Goshawk or Cooper's, and was lost under the horizon heading North. The
other accipiter was smaller in comparison to the other, a male Cooper's or
Sharp-shin. These birds weren't fighting, but they would pass close to each
other on occasion. This was probably a pair of Cooper's hawks, but the
bigger one seemed to have a very large tail almost too long for a Cooper's.
In local news, we had a lot of turkey vultures scouring the valleys for
food, but they would turn around once they get even with us. We also had a
lot of acrobatically flying red-tailed hawks flying all around us. We also
had a local coopers hawk hunting to the west/southwest and two local Golden
Eagles during the chaotic 20 minutes.
Non-raptor Observations:
We had a distant American White Pelican going North alone over Green
Mountain. There were a few swallows, probably tree swallows.
There were a lot of bugs, mostly beetles and butterflies, flying by around
us.
Predictions:
Tomorrow looks to be partly cloudy most of the day. It should reach the 70s
with a Northwestern wind. I can't wait to see you up there.

Visitors:
We had 18 visitors to the ridge today. One of these visiters was a
paraglider who was only about 50 feet above us. After we waved to him, he
started to show off and do these tight spins and turns.
Weather:
Today was a warm, sunny day with little cloud cover. The wind was an
Eastern wind today. It started more Northeast and finished more Southeast.
There was a bad haze all day today, and it most likely affected our ability
to find distant migrants.
Raptor Observations:
We had a lot of potential migrants get very high in the air before turning
around and going back to the ground. Most of our actual migrants were
either very high up or below our eye-line.
We had an osprey fly by us with a fish, a snack on his long journey North.
We had a different osprey land on top of a telephone pole above Mount
Morrison and eat a fish up there. We didn't see that osprey leave, so we
didn't count this bird as a migrant because it could of easily gone any
direction but north.
Our last 15 migrants occurred within the last 25 minutes of the survey.
There were 8 red-tailed hawks in the air at the same time, but only two
left. Three red-tailed were as high as you could possibly see, diving at
each other, but none went north.
We saw a lot of local Red-tails today, even more than usual, and their
activity was constant and throughout the day. We also had a local Golden
Eagle, a local Coopers, and a local Peregrine.
Non-raptor Observations:
We saw two groups of four American White Pelicans, some White-throated
Swifts, and the elk with the 3 and a half legs. This elk is the same as
Emma saw yesterday, it looked to be a young male missing everything below
his heel on his back left leg. He still seems to be moving pretty good, as
one minute he was there and the next we couldn't find him on the slope
again.
Predictions:
Tomorrow should be a warm day reaching the 70s. It should start sunny and
we should see clouds build throughout the day. The wind should start in the
Southeast/East and end in the West/Northwest.

Visitors:
Thank you to all of the volunteers that came out today, it got cold at the
end but I think we can all agree it was an interesting day! We had 16
visitors to the ridge today including Orion (forgive me if I’m getting
that wrong) with USFWS for the second time. Many visitors asked about the
flight and got to see some raptors come very close!
Weather:
We got some relief from the blue skies today with cloud cover first thing
in the morning. Winds were light from the N first thing and varied between
NE and NW for most of the day. In the afternoon winds picked up
considerably, reaching speeds of 20+ mph.
Raptor Observations:
Migration started off strong this morning with a good little push of CH and
RT. Jim Banks arrived at the site before I did and had a number of birds
already counted as well, so thank you! We had our typical lunchtime lull
and when the winds picked up I was nervous our flight would stay quiet but
boy was I wrong! We had an outstanding show of AK coming one after the
other directly, and I mean directly, over our heads. Birds were flying
below eye level to about 5 meters above us. Today was a great example of
why this site is so special. What we may lack in numbers we make up for in
diversity and flights (sometimes). We had AK, PG, OS, RT, SW, and CH all
come in the afternoon in the strong winds.
Local raptor activity was also very interesting today with a SS potentially
roosting along the ridge for the night after getting blown around in the
winds like a piece of plastic. RT, TV and BE locals were all seen. The day
ended with three RT all interacting for 20+ minutes. All three birds were
adults. They spent this time diving around with each other, not displaying
any aggression. One of these birds had a prey item in its talons while
diving, which was the first time I’d ever seen that. We spent the time
speculating on the relationship between the three birds and getting
incredible looks at their stooping abilities.
Non-raptor Observations:
Passerine activity was great today with SPTO and ROWR heard almost
constantly all day. As usual the corvids were out to play today, but were
surprisingly absent in the high winds.
The weirdest observation of the day, without a doubt, was a cow elk missing
its back left foot. I spotted her hobbling through Matthew-Winters park
late morning and quickly saw why that was. As I called CPW we saw JeffCo
rangers looking at the animal so knew they had been made aware of the
situation. We didn’t see CPW come out today so we will be interested to
see if they do and what they decide to do with her.
Predictions:
It looks like we will be back to staring into the blue abyss tomorrow with
little to no cloud cover predicted. Winds are predicted to come from the
NE, bringing a hopefully great flight! We hope to see you up at the ridge
as we head into the peak of the migration.

Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.

A bear tore down two of my feeders last night. I used to keep feeders up in the summer but bring them in night. In recent years we’ve had many bear visits during the day, so I’ve given up on summer bird feeding. I do put up some hummingbird feeders in high places the bears can’t reach. The bears have surprised me on occasion by getting to hummingbird feeders that I thought they couldn’t reach. David Waltman 6,000 feet; 1/2 way between Boulder and Lyons

Date: 4/10/24 9:40 am From: Rick Reeser <rcreeser...> Subject: [cobirds] Lower Latham Lake
It is always a joy to see the first of the migrating birds for the year. I spent about 40 minutes along CR 48 south of the lake in the wetland area and saw: L Scaups, coots, RW blackbirds, Mallards, Widgen, Shovelers, C Geese, Gadwall, Cinnamon Teal, and one Yellow Headed BB. I also saw GB herons, Greater yellowlegs, a BN stilt, willet, killdeer, and a meadowlark. It was an enjoyable time. There are also lots of birds at the large pond northeast of CR 46 and 37. It is not showing on some maps. It looks like a parking lot on the NE side of the road, but I think that it is private, so you need a very good scope to ID the birds on and around that lake from the road right-of-way. If someone knows more about that lot, I would love to hear from you. There is also another much smaller pond just south of CR 46 around the corner from the last one that often has a few birds on it.

Visitors:
A huge thank you to all of the volunteers and visitors that came out to
help spot and ID raptors today. As always we wouldn’t be able to do it
without you! We saw a total of 29 visitors at the ridge today with many
folks inquiring about the migration. We had multiple visitors ask about
bird activity during the eclipse today which was fun to chat about.
Weather:
We had another beautiful day on the ridge today with light cloud coverage
all day and near perfect (in my opinion) temperatures. Winds were predicted
to come from the N and did in the start of the day but quickly varied in
direction. Winds varied in direction and speed all day, with some moments
of complete stillness.
Raptor Observations:
Migration started off with a bang this morning with a close eye-level OS to
the west of the ridge followed by out first BW of the year! This bird comes
almost a year to the day of our first of the year last year. After this
stellar start birds slowed down considerably. TV have been consistently
making up the bulk of our birds recently and today was no different with
small kettles of 3-5 seen.
Local raptor activity was high today with a number of RT seen hunting,
displaying, and escorting migrant RT. Both BE and GE locals were seen
today, one GE was mobbed by two RT and two CORA for a good few minutes
before heading west.
Non-raptor Observations:
Corvid activity was great today with most birds spotted being CORA. As
always it’s nice to see them on the ridge but my oh my do they try and
pass as raptors at times. One CORA perched on the ridges telephone pole for
a few minutes calling. Passerine species seen today include TOSO, HOFI,
ROPI, AMRO, ROWR, WOSJ, and BBMA.
The non-raptor highlights of the day were a Turkey (not vulture) seen
flying right on the ridge first thing in the morning and 3 American White
Pelicans that came right overhead!
Predictions:
Tomorrows prediction looks much like todays with partial cloud cover and
winds from the general N direction. I’m hoping we will have a bigger day
tomorrow than today as the storms south of us move. There were some nice
winds from the S across New Mexico during the afternoon today, hopefully
bringing us some nice migrants tomorrow!

Date: 4/9/24 2:28 pm From: Jared Del Rosso <jared.delrosso...> Subject: [cobirds] My April DFO Program on Whip-poor-wills
Hi all --
On April 29, I'll be presenting my work on the "cultural lives" of Eastern
Whip-poor-wills during Denver Field Ornithologists' virtual program. I'll
be talking about the research I'm doing for a book on the species's place
in U.S. culture: how they've mattered to people over the centuries and what
their decline means to us today.
I've presented smaller portions of this work to the Global Nightjar
Network, as well as at some sociology conferences. But this is my first
time presenting to birders, and I'm so glad it's with DFO -- who I've
joined on trips and occasionally led trips with. It's also gratifying
because my encounters with Denver's nightjars inspired this work.
For more on the program, here's the description from the most recent *Lark
Bunting* below.
Jared Del Rosso will be giving a talk exploring the largely untold story of
his favorite bird, the Whip-poor-will. An almost mystical icon of early
American culture, the species figured prominently in the seasonal lives of
a largely still agrarian-oriented land.
His new book explores its place in the natural and cultural landscapes of
America. The story is not only about the species itself, but also about us
and how we understand changing relationships among birds, the natural
world, and our own lives.
For centuries, Americans in the eastern US eagerly awaited the return of
Eastern Whip-poor-wills to their breeding grounds. The song of the first
returning bird meant an end to frost and the true beginning of spring.
Local newspapers reported on the arrival of the birds, farmers began to
plant frost-sensitive plants, and children knew they could go barefoot
outside again. That first song was also said to predict the length of
people’s lives, grant wishes, cure backaches, and even guarantee wealth.
As ordinary folk listened for the bird, American musicians, poets, and
writers made the Whip-poor-will a legend. Country singers transformed the
birds into icons of lonesomeness and rural life. Poets and nature writers
wondered about the species’ strange, menacing name. Horror writers spun
Whip-poor-wills into the stuff of nightmares.
But with time, says Del Rosso, something has changed. Since the 1970s,
Eastern Whip-poor-will numbers have fallen by more than two-thirds. Fewer
Americans encounter them regularly. Birders must work harder to add the
species to their yearly checklists. Now the singers wax nostalgic, and
naturalists pen eulogies. The birds went from unfamiliar to obscure. Today,
they’re on the brink of forgotten.
Del Rosso who teaches at the University of Denver, is writing a book on
Whip-poor-wills for New York University Press’s “Animals in Context”
series. He is also an avid birder and has led trips with Denver Field
Ornithologists and the High Line Canal Conservancy. He’s especially
interested in nightjars (the greater family that includes Whip-poor-wills)
and is counting the days until this year’s return of nighthawks and
poorwills to Colorado. His writing about birds and birding has appeared in
this newsletter and on the Center for Humans & Nature’s blog. For more on
his upcoming book, visit his webpage at lonesomewhippoorwill.com.

Visitors:
We had 41 visitors to the ridge today. A lot of them were there to see the
eclipse, but were overjoyed to learn that there was a Hawk Watch in the
Denver area. A few visitors were alternating between binoculars and the
eclipse glasses ready to see all of the amazing sights overhead.
Shoutout to Joel Brewer, Perrin Robinson, Elissa Robinson, and Greg Yugov
for visiting us on the ridge and then hanging out for a few hours trying to
help us spot the migrating raptors.
Weather:
Today was a warm sunny day with a good amount of cloud. The winds
fluctuated between East and Southeast all day today. Around 11:30 MST there
was a partial eclipse. At our sight was about 60-65% coverage of the sun.
Thank you to Marianne and Dave Erickson for the solar eclipse glasses.
Raptor Observations:
Our early morning migrants were more tucked into their glides then usual.
Their wingtips were closer to their tails. I assume that this was because
of high, strong tail-winds.
We started off today with 0 migrants in the first hour, and then went on to
have our best day of the year so far with 113 migrants!!!
We had a kettle of 15 Turkey Vultures that might be the biggest kettle seen
at this site in the last 20 years. At least the biggest in the last 3-5
years.
We had another immature goshawk at the ridge today that gave us a great
close-up view!!
We also had our first Swainson's hawk of the year!!
In local news, we had our usual Red-tailed hawks, a Cooper's Hawk, a
Sharp-shinned Hawk, a couple Bald Eagles, and a few Golden Eagles.
Non-raptor Observations:
We saw our first swallows from the ridge today, and I believe they were all
tree swallows. There was plenty of White-throated Swifts as well.
On Green Mountain right after the eclipse we saw 4 or 5 llamas being walked
along a trail. I hope they had eclipse glasses as well, but it was too far
away to tell.
Predictions:
Tomorrow looks to be another warm, mostly sunny day with a wind mostly from
the North.
I have no idea if the high count today will limit the number of migrants
tomorrow, or if migration is just going to keep increasing. Grab some
sunblock, and maybe a wind jacket, and join Emma up there tomorrow to see
what happens on the ridge after a fantastic day.

HI Cobirders, John Williams, a friend of mine, is organizing a show of bird photography in Longmont on May 10. He is seeking submissions. Please see his request below. Send any questions, submissions, etc. to him directly, not to me. His address is below. I am also copying him on this email. Thanks, Richard Trinkner Boulder The idea behind the show at Longmont Public Media (May 10th @ 7pm) is to spotlight some of the amazing work of local photographers with this particular evening being dedicated to bird photography. It is meant to be an interactive evening with each photographer sharing seven different images (projected in our TV studio) and taking questions from the audience. Longmont Public Media will then have gallery space available for the framed prints of those photographers who wish to have their work on display through the month of May. The selection process for participants will be competitive. If you wish to be considered, please submit 7 images to <john.williams...> by April 15th. These images need to be high resolution—we will get those later should you be selected for the show. We are looking forward to a fun and insightful evening celebrating the birds of Colorado through your photography! Thanks John Williams

Visitors:
We had 37 visitors to the ridge today including a Wolf Watcher that sits on
a similar looking ridge in Yellowstone counting the number of wolves that
he sees. He plans on coming back to help us on the ridge soon.
We also had 2 visitors from Australia who were very interested in seeing
American Raptors.
Weather:
With opposite clouds as yesterday, we had nice high clouds in the morning
and had blue limitless sky in the afternoon. The sun was shining all day
and the wind was a southern wind with gusts up to 18 mph.
Raptor Observations:
Our migrants were just as high as yesterdays, but were moving even faster
because of the strong tail winds. It seemed that our migrants were not
using the wind like I thought they would. Lots of local raptors were high
up and actively flying South against the wind.
Both unknown accipiters were far away to the west of straight up, all I
could see on both were a long tail and broader wings marking it an
accipiter, but they never flapped and were too far away to tell the finer
details to tell Cooper's vs Sharp-shin.
The unknown Falcons were in the air near some turkey vultures, and looked
to be about prairie falcon size. They were falcon wings, but I'm not sure
how close they were to the turkey vulture for a size comparison.
The unknown Raptor was so high all that was seen was a brown dot moving as
high up as we could see. No wings or tail were seen just the brown dot. I
assume it was bigger than a kestrel because I doubt a kestrel could be seen
so high.
We saw a local kestrel, sharp-shin, bald eagle, and at least 6 different
red-tailed hawks. One of the red-tails we saw in the morning was leucistic
and missing a lot of feathers. I'd imagine it wasn't migrating because of
all of the missing flight feathers.
We later saw possibly the same leucistic red-tailed on a telephone pole,
and with the sun shining on it looked even brighter white.
Non-raptor Observations:
We had a possible first to the ridge with a Bewick's Wren that was both
seen and heard. We also had 2 different Rock Wrens singing and one was
seen.
White-throated swifts were everywhere today. We probably saw over 60 with
40 being in one flock. These super high migrants brought some
disappointment as they were thought to be raptors on first glance, but they
were fun to watch soar around.
Predictions:
Tomorrow's wind will be 35-55 mph with gusts to 100 mph!!!!
We have canceled the count tomorrow because of the danger of that much
wind.

Visitors:
We had 44 visitors to the ridge today including a nice person named Hampton
who might join Denver Field Ornithologists.
Weather:
A very sunny day with a light gusty wind that changed directions some, but
was mostly from the Southeast. Around 2 MST we had high thin clouds that
were a great background.
Raptor Observations:
Our migrants started low until about 11 am MST. After that all of our
migrants were really high. It is quite possible that we missed a lot of
migrants because they were simply too high to be seen.
Our unknown raptor was flying near a kestrel. This bird was bigger than a
kestrel and looked falcon-ish, but it was too far away to rule out Cooper's
Hawk. I would guess a prairie falcon, but there is no way to know.
In addition to our usual cast of local red-tailed hawks we had two local
Cooper's hawks and a local Golden Eagle.
Non-raptor Observations:
We had a leaf migrate overhead with a Height of Flight of 4. We also had 6
American White Pelicans and a few Double-crested Cormorants. Towards the
end of the day we had two sandhill cranes flying super high in the air.
We also had a lot of baby ballooning spiders today. Some little spiders
shoot a web in the air and they go where the wind takes it.
Predictions:
Another hot day that is mostly sunny and will have high winds. An over 15
mph wind will be a nice tail wind for our migrants. I expect tomorrow to be
similar to today with the migrants very high, except now they should be
passing us faster.

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
weather permitting.
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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)

Visitors:
We had 28 visitors to the ridge today not including several of their dogs
that wanted to play.
Weather:
A very sunny day with gusty Northeast and Northwest winds. Plenty of clouds
in the sky, but rarely did they block the sun. Our temperature recordings
varied a lot with the wind and cloud cover.
Raptor Observations:
Our migrants today were for the most part, very high above us or below our
eye level. I think the gusty headwinds caused this behavior. We seemed to
have more migrants when the wind was from the Northeast, but that was also
most of the day.
We had a Juvenile Red-tailed migrate that was being hotly pursued by an
adult Red-tailed Hawk.
We had a Golden Eagle that was migrating while being attacked by a tiny
bird. From our vantage point (miles away) the tiny bird was at least 1/8th
the size if not smaller than the golden, I would guess Merlin, but there is
no way to know. The same Golden Eagle was later escorted out of town by
another Golden Eagle.
Now for the one we have been waiting for, especially me, the Immature
Goshawk. From a distance we see this bird with a very long tail and
powerful flight. My first thought was a Northern Harrier until I realized
that this bird was way closer than I had originally thought. As we were
watching this bird debating Cooper's vs Goshawk, an adult female Cooper's
Hawk appeared in the view and was attacked by the Goshawk. These two birds
appeared to be roughly the same size, but the immature bird had a slightly
longer tail. After the adult Coopers left the Goshawk did a few circles
without gaining much height and then left as well. A few books were
consulted confirming Immature Goshawk. Thank you Kathie for finding the
hawk and Emma with a nice ID which as most know for an immature accipiter
can be quite challenging.
In local news we had a local Red-tailed attack a local Golden Eagle keeping
the bigger bird away from its nesting area. We also saw a couple red-tailed
hawks carrying food, either to eat themselves or to give to their mate.
I also had a lot of locals on my hike up the trail including 3 red-tailed,
a bald eagle, and a turkey vulture. All going south/ hanging around the
area.
Non-raptor Observations:
My friendly neighborhood Common Raven that is missing the two or three
secondary flight feathers was seen a few times today. We saw a different
Raven a couple times today that had something wrong with its wing. Where it
could still fly but the gait of the flight seemed very different. This
might not be as evident if we weren't seeing dozens of Ravens everyday.
WE also saw two parachuters today to the North of us.
Predictions:
Tomorrow looks to be a very warm day (touching the 70s) and has a varying
mostly southern-based wind. Bring some sunscreen, lightweight clothes, and
maybe a neck pillow because I think we will have a lot of high flying
migrants tomorrow.

Visitors:
Thank you to all of the volunteers that came out today to help spot
difficult birds! Most were rewarded with great looks at more than one
raptor species. Jim Daily, a former Manzanos HawkWatch counter, and his
friend Paul (I didn’t catch a last name) stopped by for a bit and were a
great help at spotting birds. We also had two visitors from Maryland,
Eloise and Ricky, that came to spend a few hours at the site with us and
were fantastic spotters! We saw a total of 18 visitors at the ridge today,
including two young kids at the end of the day who were very enthusiastic
about the abilities of a spotting scope.
Weather:
The ridge was a winter wonderland this morning covered in snow and ice. The
sun quickly melted this cover revealing a classically muddy trail for the
rest of the day. Winds were incredibly light for the first half of the day
coming from the general SE direction, but switched to NE and picked up in
the afternoon. The sky was blue and hazy with little to no cloud cover all
day making for challenging spotting conditions. Ajit put it well today- the
best parts of Colorado (sunny and blue skies) are often the most
challenging aspects of this site!
Raptor Observations:
Migration today started high and finished high with the last bird. The snow
illuminated many of our migrants greatly, making for some really
interesting views including a very light Merlin that came overhead. Local
TV and RT were seen today as well as a local GE escorting a migrant
through. We saw a great push of TV today but the highlight of the day was
without a doubt a leucistic RT that came directly overhead in the afternoon
giving us all an outstanding look.
Non-raptor Observations:
Many of our normal non-raptor species today were seen today including TOSO,
DEJU, BUSH, BBMA, CORA, and AMCR. Corvid activity stayed plentiful all day
but passerine activity seemed lower than normal. WTSW made a brief
appearance today. Elk could be seen near the Mother Cabrini shrine as well
as on Green Mountain today.
Predictions:
Looks like we will have another blue sky day tomorrow with winds from the W
in the morning and the potential for an E shift. Temperatures are
continuing to increase the next few days.

Visitors:
We had 10 visitors to the ridge today including one who lives in Denver,
but had a strong New York accent. The snow didn't scare off the mountain
bikers, but did seem to scare off our visitors
Weather:
Today was a day full of snow. The sun would make fleeting appearances and
the wind was shifting and gusting constantly. We saw some lightening and
heard thunder which meant we had to get down off of the ridge for about an
hour.
At one point we had surface clouds moving Southwest, above that the clouds
were going North, and even higher the clouds were moving Southeast.
Raptor Observations:
Our migrants were pretty high today especially in the morning before the
snow started falling thicker. We had two separate kettles of 6 Turkey
Vultures.
A lot of our migrant's feathers were messed up, I assume because they were
wet from migrating through precipitation.
We had our usually local red-tailed hawks somewhat subdued today and a
local kestrel around sub-peak.
Non-raptor Observations:
We saw a Common Raven carrying around what looked like bread, but could
have been a rock, in its beak.
We had a few white-throated swifts fly past us as well seeming to not care
about the wind and precipitation.
We also saw a lone bushtit a few times today. The species itself isn't
rare, but seeing one by itself is definitely strange.
Predictions:
Tomorrow looks to be a sunny day with a head-wind all day.

Visitors:
We had 74 Visitors to the ridge today. Three of them were small children
who were able to look through our binoculars to see mule deer close up.
Weather:
Today was a partly cloudy day full of fairly strong winds and the haze
again today.
Raptor Observations:
Today we got a new highest count for the year. There were a lot of
accipiters and for the most part migrants were low today.
We had a kettle of 5 turkey vultures, a first year red-tailed that had both
juvenile and adult plumage, and a probable male sharp-shinned hawk fighting
the wind more than some of the others we saw.
We had a local Red-tailed hawk chase a common raven away from its nest, and
probably a different red-tailed hawk catch a mouse and eat it on a
telephone pole. We also had a local Turkey vulture and a sharp-shinned hawk
with full crop.
Non-raptor Observations:
We had a large group of Woodhouse's Scrub-jays, a few Black-capped
Chickadees, a couple Mountain Bluebirds.
There were a couple groups of mule deer found to the west, the east, and on
our ridge on the western side.
Predictions:
Tomorrow looks to be full of rain and possibly storms. I'll look again
tomorrow but a shortened count tomorrow is likely.

I was birding at Hudson Gardens yesterday morning and saw a Common Grackle
at the feeders.
We also saw a couple of Cliff Swallows over the Platt River - first of the
season.
They're back !

Date: 3/31/24 7:37 am From: R Carol Cushman <r.cushman...> Subject: [cobirds] California quail (but maybe an escapee) for your list
Hi Thomas,
A California quail appeared in my yard on Baseline Road in the early 1960s. I was taking an ornithology class from Dr. Gordon Alexander at the time, and he said it might have been an escapee, which seems probable. Are you counting escapes?
Over the 60+ years that I’ve been birding, there have been so many memorable moments. When we lived on Mariposa, Bluebell Creek ran in the backyard and was like a highway for wildlife. Once I heard a bird song and said, “If I didn’t know better, I’d think that was a cardinal.” It WAS a cardinal—a female. First time I realized female cardinals sang. When we first moved there in 1973, Steller’s were the only jays.Then blue jays moved in and were dominant until the scrub jays arrived and lorded it over the other two species. Scrub jays would come to the bathroom window to remind me to replenish the peanuts.
A brown thrasher once spent the winter near our feeder when we lived on a slice of land surrounded by Teller Lakes Open Space. While we lived there we got a few one-day wonders: sage sparrow, red-headed woodpecker, and yellow-billed cuckoo. We occasionally had peregrine falcons and sandhill cranes and often saw osprey and bald eagles. Isn’t it wonderful that bald eagles are now almost common!
My most memorable moments were during the six years when a pair of Swainson’s hawks nested in a willow very near the house and successfully raised young each year. The protective parents were o.k. with us until the young fledged. Then they became so belligerent that I had to carry an umbrella to flourish when they dive bombed me. Or, maybe the most memorable moment was the time during a light rain shower when a great horned owl, who had been incubating in a nest near our home, decided the endeavor had failed. She flew up to branch, lifted her wings, took a long shower, and left. The male stayed around the nest for several days, sometimes looking into it and appearing disconsolate.
Now that we live in a retirement community, I’m thrilled just to get a kestrel perching on the balcony railing.
A mouse (or kestrel) is miracle enough,
Ruth Carol Cushman

Visitors:
We had 43 visitors to the ridge today. We have had a lot of visitors the
last couple days wearing Chicago cubs (baseball) gear. Which I thought was
an interesting observation since they were not playing the Rockies, and as
a St. Louis Cardinal fan we had some fun banter.
Weather:
Today was a warm mostly sunny day with strong winds that changed from a
Southeast to a Northeast throughout the day. There was a bad Haze over the
entire area especially to the south of us.
Raptor Observations:
Most of our migrants were very low today. Even our far away migrants were
close to the horizon.
We had our first loose kettle of 3 turkey vultures, and a coopers hawk that
was momentarily thwarted by the wind before moving north.
We had an immature bald eagle do what I call the wave (or saw) technique
while migrating that I have mostly seen in Red-tailed hawks. Going into a
head-wind the raptor tilts its wings up to gain height before diving down
and forward then repeat. This gains distance without having to flap, and
usually only lasts for a few minutes.
The unknown accipter was about a mile and a half away (under cabrini
shrine) and was under eye level the entire time. This bird flapped a lot
(uncountable), but the flaps looked stronger. This bird was most likely a
Cooper's Hawk, but I couldn't be sure it wasn't a Sharpshin as the far
away, brown bird had a green/brown grass background where it was
disappearing for a few feet before reappearing.
We had an evening surge of kestrels where we had 6 migrating kestrels after
3 MST (4 MDT).
Today we had a local Turkey Vulture, Merlin, year 4 Bald Eagle, and an
accipiter probably a Coopers flying south to the east of us under a migrant
red-tail (So I looked away before an ID was made).
Non-raptor Observations:
Today we saw my first ever white-throated swift!! This bird was by itself
and flew north as a non-raptor migrant.
We also had mule deer on green mountain again, and saw a person in a
parachute from pretty far away.
Predictions:
Tomorrow looks to be a warm and overcast day with a strong southwest/
tail-wind. Should be a great Easter, and I look forward to seeing those who
will join me on the ridge and maybe their families.

Visitors:
We had 14 visitors to the ridge today, one person might become a member of
the Denver Field Ornithologist along with his father who wasn't there.
Weather:
Today was a very overcast day that got colder as the day went on. The wind
started from the Southeast and shifted to the Northeast.
It threatened to rain on us and multiple times we had very light rain or
snow that we could see, but not really feel. In the last hour, it switched
to an off and on light drizzle, but my persistance was rewarded.
Raptor Observations:
Our migrants were mostly straight above us and close due to the low clouds
and almost constant precipitation around us.
As we were watching a migrating red-tailed a second red-tailed appeared
roughly 3 times higher up than our migrant. The higher bird tucked its
wings and dove straight at the migrant. When the local bird made contact
there was a small puff of little feathers came off the migrant. The local
attacked many times before it turned around leaving the migrant to go
north.
Our first Sharp-shinned hawk was very tiny suggesting that it was a male.
This hawk was about 40 feet slightly above eye level.
We saw a pair of Red-tailed Hawks, what I believe was a different pair than
the day before, copulate along the western ridge.
Non-raptor Observations:
We saw lots of moving passerines in all directions. Mostly American Robins
and Mountain Bluebirds, but there were a few where none of us saw the
species.
A few mule deer were within 60 feet away from me on the way down the trail.
Predictions:
Tomorrow we should have a sunny day with an ever changing wind. The trail
should be muddy in the morning and dry out pretty well over the course of
the day. Bring some sunblock and I'll see you up there.

Official Counter: Dustin Kohler
Observers: Ajit Antony, Chip Dawes, Dave Erickson, Lori Morton,

Visitors:
We had 25 visitors to the ridge today who varied from super interested to
being downright disrespectful and went off trail despite the directions we
gave. Hopefully, we will see most of these visitors again.
Weather:
Today was a very sunny day. The sky was cloudy most of the day, but the
clouds were very thin and wispy. It gave a nice background to view
migrants.
The wind started from the Southeast, and it switched to an eastern
(cross-wind) which did seem to affect migration.
Raptor Observations:
Most of our migrants were directly above us or to the west of us.
We had two local Turkey Vultures one of which was a juvenile. One of the
two turkey vultures was being hounded and attacked by a Red-tailed hawk.
We saw Red-tailed hawk courtship a few times, and a local male kestrel
flying south.
Non-raptor Observations:
We saw the same raven pass by at least four times. We could tell it was the
same one because it was missing 2 or 3 secondary flight feathers.
We had my first on the ridge Stellars Jay today that stuck around for a few
moments.
We also had a herd of about a dozen elk, and another herd of about 15 mule
deer both around bare slope.
Predictions:
It's possible I looked at tomorrow's weather for this section yesterday. It
looks to start raining around 1 and keep raining the rest of the day. The
temperature looks to be in the 40s with a moderate wind shifting from the
east to the north.
I'll be up there until the rain is super strong, or it becomes clear that
nothing is moving in the rain. As always if it builds into a thunderstorm
we will leave the count early.

Visitors:
We had 7 visitor to the ridge today, a few of which I believe will come
back and see us again.
Weather:
Today was a great day weather day. There was a Northwestern wind all day
and temperatures fluctuated with the wind.
We appeared to have a consistent surface wind, and most of our migrants
were able to fly above the wind with little trouble.
Raptor Observations:
Most migrants in the morning were very high over the headwind. Once the
winds got stronger the migrants were lower and struggled more.
In the morning we had a harrier chased south by a couple red-tails and a
Turkey Vulture fly due west.
A golden eagle tried to head north to the west of us and got chased by a
pair of red-tailed hawks. He then tried to head north along our ridge and
got chased back south by another pair of red-tailed and we didn't see it
again.
Later on a Sharp-shinned hawk appeared to try and migrate and got thwarted
by the wind. It tried a few times before appearing to give up and settle by
mount morrison.
We saw a local Red-tail carrying a vole (small rodent) two different times
today about 4 hours apart. We later saw two red-tailed copulating to the
west of us.
Non-raptor Observations:
We had a few Townsend's Solitares hanging around the ridge all day.
There was also elk along bare slope where they usually hangout.
Predictions:
We should have the temperatures in the mid-forties with a shifting wind
from the southeast to the North. With that shift in wind there will be rain
starting around 1.
Depending on the strength of the rain and how the sky is looking will
determine if we shorten the count tomorrow.

Date: 3/27/24 2:50 pm From: David Matson <wrenpt...> Subject: [cobirds] yard list
Dear Colleagues:
I am late to the table.
We moved to our current location in Huerfano County in 2018. We have a few pines, mostly Gambel's Oaks and a good bit of various grasses. We have counted far more wildflowers and grasses on our land than bird species.
Thus far, our yard list stands at 112 bird species. We are in Woodhouse's domain, having both 'his' toad and 'his' jay. One Great Blue Jay has flown over heading to one of the town lakes and Canada Geese enjoy the watered grass at the golf course several miles away. Bufflehead have dropped in a seasonal pond a couple of times.
Sharp-shinned, Cooper's, Merlin, and American Kestrel follow the other migrant birds, while Red-tailed, Rough-legged, Golden, Bald, Northern Harrier, and Osprey have a more stable or predictable occurrence.
Sandhill Cranes are heard move often than seen, although like the plane causing a contrail, if you attend to the source, you eventually can see them.
Gulls are notably absent--a drive to Lathrop State Park or a 1 1/2 drive to the Pueblo Reservoir is needed to reliably see one.
Doves are daily visitors to our dripping water in the summer: Mourning and Eurasian Collared. Otherwise, they would need to fly three miles to reliable water.
Great Horned and Mountain Pygmy (two notes), as well as Common Nighthawk and Common Poorwill are reliable here.
Five hummingbird species come to our feeders, the first around April 15, with an influx of Rufous around July 1. Rufous are dominant then. We enjoy the infrequent Calliope.
Lewis's Woodpecker is a regular down at the bridge, yet has been curious about the activity at our water feature and feeders two or three times.
An Ash-throated Flycatcher made one late-summer appearance as did a Sage Thrasher.
A lone Vesper Sparrow is here each year and we had a single Western Wood-Pewee the first year after the Spring Fire that ravaged our Gambel's Oaks.
That fire went right over our house, fortunately leaving the house standing--thanks to the local fire-control efforts. Thus, we are observing what happens to an ecosystem as it recovers from such devastation.

Official Counter: Ajit Antony
Observers: Janet Peters, Natalie Uschner-Arroyo
Visitors:
9 visitors to the watch. Thanks to the help from Janet in the morning and
Natalie in the afternoon and for each of their help this past month on
Tuesdays during my counts.
Weather:
That day after a snowstorm, light winds from the ENE, high humidity with
decreased visibility. There was a large area of fog far to the south which
gradually made its way north partially covering Warren Peak. Dawson Butte
could not be seen all day until the last one half hour.
The lowest part of the trail to the watch was a sheet of clear ice from
snow melting during the day and freezing at night. My crampons and Janet's
YakTrax kept each of us stable and safe.
Raptor Observations:
Not much of a migration today, with no migrants in the morning and a
smattering in the afternoon. Janet's observation was that at this watch,
the day after a snowstorm has very few migrants, her hypothesis being that
they are busy foraging for food which they could not find during the
snowstorm, so tomorrow could be better for migrants.
The best migrant of the day was a dark morph adult RT at 2:29 PM MST with a
dark body and coverts and a light red tail, and just before that we had an
adult male Northern Harrier – both of which were new for Natalie.
That we could see 11 non-migrant RTs, and with favorable cloud cover, I'm
guessing we weren't missing many migrants.
An adult GE close enough to be naked eye to the north flew to the NW and
dropped in front of the ridge, a non-migrant.
Non-raptor Observations:
Townsend's Solitaire 2, Woodhouse's Scrub-Jay 4, Spotted Towhee 1, American
Robin 1, Common Raven 18, American Crow 5 , Northern Flicker 1, Bushtit 2,
American Goldfinch 2.
Predictions:
The forecast is for mostly sunny skies with a high near 48°F, NW winds
6-10 mph with gusts to 16 mph.
