Like John, I wasn't opining that the Estes Park bird was likely an escapee. (On Sat., I thoroughly enjoyed spending an extended time observing it.) I was merely pointing out that Yellow Grosbeak is known to be a caged "pet" bird in Mexico, where the relevant laws are different. Although Mexico is a signatory to the Migratory Bird Treaty, it complies with the Treaty with a different set of its own federal regulations. The trade in pet birds in Mexico is supposedly "controlled" by those Mexican regulations; how effectively it is controlled is open to question. For an overview of the pet bird trade in Mexico, here's a link to an open access article entitled "The use of birds as pets in Mexico" that was published in 2017 in the Journal of Ethnobiology and Ethnomedicine: https://pmc.ncbi.nlm.nih.gov/articles/PMC5470262/

Hi all,
In 2006, I drove all the way to Albuquerque to see a Yellow Grosbeak. That bird, I believe, was NOT accepted by the New Mexico Bird Records Committee. It had three strikes against it:
* It had a bill deformity, which can be common in captive birds;
* It seemed unnaturally tame;
* It showed up in winter. (Summer is the expected season for wandering Yellow Grosbeaks.)
The current crop of vagrants doesn't suffer from any of those suspicious traits.
Furthermore, this species has established a pattern of vagrancy north of Mexico this year. The Estes Park bird is the fourth this year (!!!!) for Colorado, after birds in Arapahoe, Hinsdale, and Gilpin counties. Arkansas got its first Yellow Grosbeak a few months back. Something is probably happening to drive the species out of its normal home range in Mexico.
To sum up: all signs point to the Colorado grosbeaks being wild birds.

I think the possibility of an escapee is considered for all reports of
Yellow Grosbeak out of range, at least at some level. Fwiw, there is
another report from the mountains (even more so) in CO from this June 9 at
Lake City in Lake County (per eBird).

Scott, I agree.
This brings to mind birds like Tropical Parula, Streak-backed Oriole in the
middle of winter, Hooded Orioles, Black-chinned Sparrow, Red-flanked
Bluetail (Wyoming) and Lawrence's Goldfinch which are the ones I can think
of off the top of my head. Some of these I didn't hear about because they
weren't reported on Cobirds (old gripe), but that's besides the point. Of
this short list, the Streak-backed is the most obvious to me. You have a
good point.

It’s interesting that only when the bird appears in estes that it becomes
thought of as an escaped bird.
How come it wasn’t thought of as an escapee when it was found farther south

I wonder where they are (were) kept as caged birds? Native song birds are illegal to keep as pets, and the Migratory Bird Treaty Act covers the Yellow Grosbeak. I would assume (and hope) the Colorado sightings are not previously caged birds.

Hi David,
You bring up a good point regarding the Yellow Grosbeak(s)? in Colorado,
which have now been documented in four counties(!). There has been a spate
of unusual sightings of birds in Colorado recently including Black-bellied
Whistling Duck and Anhinga in Boulder County; Hooded Oriole in Gunnison
County; Lawrence's Goldfinch in Huerfano County; Cactus Wren in Otero
County; Cocos Booby in Baca County; Crested Caracara in Pueblo County;
Black-chinned Sparrow in Montezuma County; and just today, Tropical
Kingbird in Arapahoe County. Wow!
Reporting sightings like these to the Colorado Bird Records Committee
<https://cobirds.org/cbrc/> ensures that they will receive careful scrutiny
as part of a rigorous peer review process including discussion regarding
providence, which takes into account the possibility that birds may have
escaped from captivity. When the CBRC accepts a record, it becomes part of
the state's official list and is archived within the Denver Museum of
Nature and Science. The online reporting process is fairly easy and well
worth the effort!
Best,
Peter Burke

With it you can trim down a recording to the snippet containing the
interesting parts and save it in a number of formats.
You can also enhance a recording. There are many options you can explore
or simply keep it simple and trim a recording.
I have more experience using it to create ring tones for Android or iPhone
from MP3 popular music song recordings, but it will read/write the .WAV
format that Merlin uses just as readily as MP3 and several other formats.
Merlin saves your recordings on your phone and you can easily copy them to
your computer for editing.
Good luck,
Chip

Apparently, Yellow Grosbeaks are known to be kept as cage birds. In Rare Birds of North America by Howell, Lewington & Russell, the authors state, "Because yellow grosbeaks are kept in captivity (Hamilton 2001), extralimital records in both time and space are open to question." They then give several examples where various state records committees have not accepted extralimital occurrences, as well as cases where such occurrences have been accepted. They end their discussion of the topic with this: "Observers should not assume that extralimital records of this species are escaped cage birds, and all such occurrences should be carefully documented."

Date: 6/29/25 10:21 pm From: Marty <wolfmartinc...> Subject: [cobirds] The flicker and the mountain cottontail
Greetings Cobirders,
I have to share (in description, as I didn't get any photos) what I
witnessed earlier this (Sunday) morning, & have been processing since...
I was upstairs with the door & windows open, doing stretches/tai chi etc
when I heard distress/pain calls outside--and on looking down saw, in the
grasses & forbs along our neighbors' driveway what appeared to be an adult
cottontail rabbit on top of some other creature which was screaming in pain
or terror.
A few robins had gathered around and started scolding, which then were
joined by a flicker that landed on the driveway and, while giving the
"kyeer" call a couple times, hopped right up to the rabbit--which then
released its captive and ran a few feet away.
At that point I was thinking the victim was a bird, but couldn't see it
very well so I went downstairs to grab my binocs & ran back upstairs. It
was in fact a female flicker, obviously injured but quiet now that its
attacker had withdrawn. But then the rabbit jumped back on top of it and
held it pinned down and appeared to be pulling feathers out with its mouth
(and the flicker resumed its cries of pain/alarm immediately). I could not
believe it. For some reason at that point the robins AND the other flicker
flew off, but the rabbit continued its mauling for a few more seconds, then
jumped back off.
WTF? I yelled down at the rabbit, and it just froze, a few feet from the
flicker. I went downstairs & outside to scare it off, but when I got out
there the rabbit was nowhere in sight. The flicker was obviously quite
injured (I couldn't see any blood, but it was crippled and trying to scoot
using its wings as crutches, and losing its balance, rolling forward
etc)... I really didn't think there was anything I could do for it, and was
reluctant to handle it in case it could be infected with H5N1 or
something...
Do we have any mammalogists or lagomorph specialists in our cobirds family?
If anyone has thoughts or experience with an interaction like this, please
reply (privately if our good moderator feels this isn't about birds so
much). Pretty baffling.
Now I don't want to hear about the rabbit that launched a swimming "attack"
on Jimmy Carter in his fishing boat, nor about the Killer Rabbit that held
off King Arthur's men in "Monty Python & the Holy Grail"...😜 But I've
never seen rabbits & (non-raptor) birds be anything but congenial
cohabitants in the yard, and never heard of anyone reporting a rabbit
attacking a bird. (When I google it, most of the "hits" are about hawks
preying on rabbits--Not what I asked, but thanks, AI.)
I did look up and found out that rabbits can (but don't often) get rabies,
and one type of response is uncontrolled aggression & biting. I also
considered that maybe it was a momma rabbit on the defense with little ones
in a burrow under a tall grass clump, and the flicker went poking for ants
too close--but found no sign of that when I poked around (only a bunch of
flicker contour feathers).
Please don't dismiss me as nuts or unreliable, this actually happened.

Hmmm, it appears that YEGRs have been seen in AZ, NM, CA, CO and IA, so
perhaps an occasional appearance isn't out of order. You may recall that
one was seen in Huerfano Cty in May of 2021.

OK, Cobirders,
so I used Audacity to do minor start/end editing & to "normalize" the recording I had made the night of June 27 with Merlin. Sorry, still some annoying if scattered background noise, and all the silence in-between call series (which occur at 01"-06", 09"-10", 22"-24", 36"-42", 56"-1'02", 1'47"-2'04", 2'12"-2'16", 2'52"-3'04", and 3'42"-3'52"). The better series are in red.
Not like any juvenile GHOW I've heard previously, but what else could it be? Not a mule deer or its fawn, or a dog, or any other owl (or nightjar) I know of. No adult GHOW were calling here that night, tho they often are. 2025.06.27_22.46_Young GHOwl or what_ hootcall series.wav <https://drive.google.com/open?id=1pUVw4DuV8qE7rSSsizBiwCayKj2tTSRa> Thanks for your input.

I believe that the Merlin app is a secret weapon attracting more people to
birding. More and more as I am out birding, I get approached by walkers,
bikers or runners wanting to visit about what birds I am seeing. And more
often than not, Merlin comes up in the conversation. These are folks that
are not birders but definitely are getting interested in birding because of
Merlin. Many of them mention their surprise at the number of species that
Merlin ID’s in their own backyards. I think that Merlin is the new spark
app that will bring in a lot of new birders.

I use the “Recorder Plus - Audio Editor” app on my iPhone to edit my Merlin
recordings. It costs $4.99 per year and runs only on iPhones I believe. You
can trim and normalize your Merlin recordings with this app directly on
your iPhone. Therefore, when in the field or on a longer birding trip, you
no longer need to transfer the recording to a computer. Just work them on
the phone and then upload them to your eBird checklist. The app is easy to
use and certainly speeds up the process of getting an edited version of
your recording on to your checklist. You can also delete sections of a
recording, but eBird discourages this in most cases.

A couple years ago I was hearing a sound at night I couldn’t identify.
Merlin twice identified it as a sora. Living in the suburbs of Louisville
this seemed exceedingly unlikely. I was finally able to see the bird, a
young great horned owl. It would be nice to be able to update Merlin with
that “song”!

I've enjoyed the stimulating conversation about the Merlin Bird ID app;
thanks to Paula Hansley for getting it going in the first place.
My take: By far the most valuable output from Merlin is the scrolling
spectrograms of birdsong; the ID suggestions are of distantly secondary
value. Here are a couple of case studies from earlier today, Sat., June 28:
First, at the Big Bluestem Loop Trail, Rocky Mountain Arsenal National
Wildlife Refuge, Adams Co., my companions with Denver Audubon and I were
enjoying a spectacular show by at least five sage thrashers, a species that
comes up with the dreaded "red dot" on the eBird app. So we needed proof.
Well, we took photos. :-) But I also quickly ran Merlin, and you can
totally see the herky-jerky phrasing in the spectrogram. Yes, "According to
Merlin," but the proof is in the pudding: the actual spectrogram, as
diagnostic as any photo of the species. Here ya go:
[image: real time output.png]
Now let's be honest. Reading a scrolling spectrogram in real time whilst
the bird is under observation isn't for everybody. That's totally fine.
Which brings up the second and, I would say, even more powerful case study
from earlier today. Before all the sage thrashers, as I was pulling up at
the refuge gate shortly before sunrise, I thought I heard a Brewer sparrow,
another "red dot" species. The song was distant, the prairie was still
pretty dark, and I needed an assist from Merlin. Sure enough, Merlin
reported Brewer sparrow. But was it really that species? I'd moved onto
something else, but I still had the audio because Merlin doesn't dump your
recordings; the user has to do that. So I clicked on the file; and then
clicked on the name of the bird; and, then, *voilà*, Merlin took me right
back to the exact point at which the bird started singing. And you can
totally see the diagnostic spectrogram:
[image: reviewed ouput.png]
I ran that diagnostic just a minute or so later, whilst in the field, but I
could have done it back home this evening—or even weeks or months later.
Merlin never forgets. (By the way, we documented an astounding 25 Brewer
sparrows at Big Bluestem; also 7 Cassin sparrows there.)
As an eBird reviewer, and on behalf of all the eBird reviewers in Colorado
and elsewhere, I'm practically begging you: Include the audio from Merlin!
Imagine getting killer photos of, oh I dunno, a yellow grosbeak in Larimer
Co., and simply stating: "Merlin." Same deal with relatively more prosaic
birds like singing Brewer sparrows and sage thrashers at The Arsenal at the
end of the third week of June. Upload the audio, and an eBird reviewer will
do the rest; for particularly tricky outputs, we'll appeal to Nathan
Pieplow to figure it all out... ;-)
A participant in this morning's field trip made an excellent analogy with
reading an x-ray. Most doctors would probably want to, you know, *actually
examine the image*, rather going solely off an AI's best guess that it was,
say, a transverse fracture of the distal radius.
The convo here at COBirds all started with the concern that Merlin had
misidentified a yellow-breasted chat as a lesser goldfinch. Did that really
happen? Perhaps. Both species are exceedingly protean in their utterances.
But we have the spectrograms!—really! we do! So we can go back to the
soundfile, click on the name of the species, get popped right back to the
presumptive lesser goldfinch, and see whether it was that species or
perhaps a yellow-breasted chat.
Two other matters have arisen in the course of this interesting discussion.
1. The accuracy of the Merlin Bird ID app. It is, in a nutshell, fantastic.
My sense is that we have crossed the "Garry Kasparov rubicon" with Merlin;
or, if your inclinations lie elsewhere, the "Lee Sedol rubicon." Merlin has
become that good. Here in Colorado, maybe Christian Nunes is still better,
but, as brilliant as Christian is, Merlin is learning *much faster* than
Christian, a mere human, can ever hope to. It won't even be close in five
years, perhaps not even one or two years. I firmly believe that we humans
will always derive immense satisfaction from recognizing birdsong without
AI assistance. But that's different from being better than AI. We're not.
Computers figured out how to beat the world's best chess players several
decades ago, and the world's best go players in the past decade;
identifying birdsong is, let's be honest, a comparatively trivial
undertaking.
2. Human sensory perception *vis-à-vis* electronic gadgetry. It is true
that our human ears and our smartphones' microphones are, in the broadest
sense, "the same thing": Both are, to be technical about
it, transducers—which detect sound energy, convert it to an electrical
signal, and transmit it to a receiver. But the analogy breaks down when we
compare what happens in the auditory cortexes in our brains with the
motherboards in our devices, with substantially different capacities for
processing the dynamical properties of frequency sensitivity, simultaneous
inputs in acoustically complex environments, and the subjective impressions
of amplitude, intonation, and modulation as they relate to the
interpretation of natural sounds. In plain English, what we notice (what
our brains think is "important") isn't the same as what the computer
notices.
Finally, here's something that the AIs don't yet have on us—and that I have
a hard time envisioning ever will: our deeply moving response to being on
the prairie at sunrise. The "mental" component of it—"that's a lark
bunting, told by its flight call, rising quickly through the 3kHz
band"—isn't really the point, is it? Rather, the entire experience: the
fresh morning air, the sunshine on our flesh, the twinkling spiderworts and
luminous globemallows; and most of all, the human camaraderie, taking it
all in, smiling together at a funny-looking beetle on the path, laughing
out loud at bison rolling in the dust, learning and sharing and wondering
together.

Last night I had what was likely a young Great Horned Owl in a tree out back, making a repeated call I didn't recall hearing before (not at all screechy or harsh). Of course I couldn't make a visual observation, and Merlin made no suggestions for sound ID.
But I have a long Merlin recording, with especially long spans at the beginning and the end of silence (except for crickets and the clock ticking on the wall beside the window).
Is there any way to edit, or a program you can export a Merlin recording to in order to edit out chunks of silence?? (This recording goes on for over 5 minutes, with a fair amount of it.)
Thanks for any help.

Hi all and happy summer. Just got back from a month in Australia (180 lifers) and it was a wonderful trip. So I am getting my feet back on the ground here locally and have been out to visit some of the usual summer haunts.
Of particular interest is that Black Phoebes (a pair) have returned to a bridge in Rio Grande County, where I documented the first record for their breeding in the San Luis Valley a while back (*Colorado Birds*). It is nice to see them return.
In other birdsy news, I am hearing reports of a Greater Roadrunner in the Valley.
Anyway, regards from here!

Female broad-tailed hummingbirds are ferocious in defense of a nest. I have seen them go after fox squirrels many times and even watched one female run off a fledged Great Horned Owl oblivious enough to land in her nest spruce.

Subject: [cobirds] Hummer help - Arapahoe
This afternoon, I watched a hummingbird that I think is a Broad-tailed dive at Lesser Goldfinches. In flight, the hummingbird flashed its tail, which included noticeable orange coloring. The hummingbird was definitely not an adult male. It lacked the gorget and didn't make the trilling call during its dives. It's throat seemed spotted. The light's a little tough for clean views with my binoculars, whose lenses aren't clean enough for a clean view of a tiny bird in tough light. I lost the bird during a trip inside to nab my camera.
So if I have the identification to species correct: is this a first-year male? Have they already left nests (I suspect not, at least around here)? Or do the females also dive at other birds? (I'm not seeing a reference to females Broad-tailed Hummingbirds diving in Birds of the World.)
I'll work on getting a better view...or better yet, a photo.

Birdy morning in my west Centennial yard today. House Wren parents were diligently feeding noisy and active fledglings. So, too, were Black-capped Chickadees, Robins, and Spotted Towhees. Sunflowers attracted Lesser and American Goldfinches. A White-breasted Nuthatch briefly visited. And an intergrade Northern Flicker, with a bright red malar what seemed to me like a fully formed red crescent on his nape, stood out. (Intergrade flickers aren't unusual around Centennial, but rarely is the red patch so extensive.)
On a mid-afternoon bike ride along the High Line Canal Trail, I thought I heard a Western Flycatcher. Maybe, maybe not. I also heard a Chipping Sparrow. Noting that because of the recent question on metro area Chipping Sparrows.
From what I can tell, Chipping Sparrows, a few juncos, and those previously mentioned Western Flycatchers all seem to nest around the west Centennial, Greenwood Village, Cherry Hills Village area along creeks and the High Line Canal Trail. And they have for much of the time I've been down here (since 2016).

Before we moved from our old house in Central Highlands Ranch, 10 years ago, there were several pairs of Chipping Sparrows that nested in pines every year in open space, just west of Highlands Ranch Mansion.
We now live a couple miles Northeast of that location near Dad Clark Gulch. Highlands Ranch Parkway/University vicinity. For the first time in 10 years, We had a calling Chipping Sparrow in a deciduous tree in front of our house. He sang for almost three weeks and now I’ve not heard him for a few days. I’m assuming he’s moved one.

All,
With the advance of climate change, I'd expected bird species to be moving
to higher altitudes, not lower. Regarding the Chipping Sparrow and other
species that Dave mentioned, plus the Western Flycatchers that have moved
into urban Colorado Springs, is the movement primarily food related?
Dave, and others, what are your thoughts?

I have had nesting Chipping Sparrows in my neighborhood for at least 3 years. I live in Bow Mar,[Littleton], one block away from Denver. They have been nesting in non-native juniper shrubs which are around three feet in height. I see the parent flying into the shrubs with food. Last year,2024, three young came to my bird bath, which was fun to watch. ONE Chipping Sparrow spent a whole winter in my YARD from 2023-2024.
There are many non- native Juniper shrubs, along with plants that form habitats with different vegetation heights of plants in my neighborhood. I have tiered clumps of plantings. No Chipping Sparrow has nested on my property yet, but I keep hoping.

Today I found one "carrying food".
Question: Are others also finding Chipping Sparrows seemingly nesting in the Metro Area this year or in the last couple of years.
As Bob Righter pointed out a bunch of years ago, at that point Red-breasted Nuthatches had become year round residents of the Metro Area. The same with Bushtits. Are we now seeing a change with Chipping Sparrows?

Yes; in my experience they are nesting here in Littleton. They built a nest
in a ponderosa, at least 15-20 feet off the ground in a neighbor’s
backyard. At least one baby fell out and later died. Another that was
definitively older was also found out of the nest, but it had more mature
feathers and open eyes. I suspect it came from a different nest, as I saw
at least 3 adults when I was attempting to help the other baby.

Date: 6/23/25 10:59 am From: Marty <wolfmartinc...> Subject: [cobirds] Edison BBS summary, El Paso
Greetings, CoBirders,
This past Thurs (6/19) I did the first of my two breeding bird surveys, which was out in the far southeast corner of El Paso County. It was pleasantly green out there, but without any playas, or water rushing in normally-dry creek beds, or muddy roads as I feared, considering the frequent rains in the past 4 weeks. [image: IMG_2407be.jpg] It was a 13-yr high count of Lark Buntings, at 163 a bit over twice the average for this route; plenty of Mourning Doves & Western Meadowlarks, maybe a bit below average on Horned Larks. Above-average on Mtn Plovers (not so many, but 12 vs the more typical 1-3), and slightly above-average for Com. Nighthawks. [image: IMG_2389bee-6.19-7.42am-Stop 22.jpg] [image: IMG_2402be.jpg] Below-average on a number of species-- L. Shrike (2 on scouting day, none on countday) & Burrowing Owl; NO Grasshopper Sparrows (well, MAYBE? 1 on the previous scouting day, but thru the everpresent chorus of Lark Bunting songs it was hard to say for sure). No Scaled Quail, fewer than average hawks and Cassin Sparrows (tho still a good number of the latter).
I tallied 26 species (the average over 13 yrs) on countday, with 3-4 others seen or heard only on the preceding scouting day. Oh, and as always, lots of Pronghorn & Black-tailed Prairie Dogs... and 2 nice-looking Black-tailed Jackrabbits. The prairie dog colonies seem to be slowly moving back farther from the roads over time, making it more difficult to pick out Burrowing Owls (especially during the 3-minute Stop limit!)--I found a definite 4 on my unrestricted scouting day, an uncertain 2 on count day...
This Wednesday I head down to the San Juans (Rio Grande County & Natl Forest) for my other BBS. Good birding.

southeast of town we have sometimes had nesting Mountain Chickadees and

The Yellow headed blackbirds are fledging and all over my yard. they are cautious, but not really scared of people. I've only noticed the males feeding the fledglings. Is that the way this works or am I just missing seeing the females? They seem to be all over the other side of the road at the lake.
I've attached a photo of a very hungry fledgling following its father around my yard.
Not the best pic, I screenshot it from the video I took.

Date: 6/22/25 4:18 pm From: DAVID A LEATHERMAN <daleatherman...> Subject: Re: [cobirds] Chipping Sparrow Question? - Metro Area
Chris et al,
Chipping sparrows have nested in small numbers for most years in the last10 at Grandview Cemetery in urban Fort Collins (elevation about 5000’ ASL). Other occasional but regular foothills species nesting at Grandview have been Broad-tailed Hummingbirds, Red-breasted Nuthatches, Ruby-crowned Kinglets, Western Wood-Pewees and Bushtits. A Western Tanager nested at Grandview a few years ago, as did a Red Crossbill. I think all of this is influenced by habitat maturation and climate change, probably mostly the former. The recent increased reporting of Western Flycatchers at low elevation seems part of this phenomenon, also.

Subject: [cobirds] Chipping Sparrow Question? - Metro Area
Hi COBIRDERS,
Where: Suburban neighborhoods just west of the Denver Tech Center, Arapahoe County
When: First 3 week of June 2025
I have found a number of adult Chipping Sparrows in our neighborhoods and parks each week of June this year. They should already be nesting up in the Ponderosa Pine forests of the Front Range.
Today I found one "carrying food".
Question: Are others also finding Chipping Sparrows seemingly nesting in the Metro Area this year or in the last couple of years.
As Bob Righter pointed out a bunch of years ago, at that point Red-breasted Nuthatches had become year round residents of the Metro Area. The same with Bushtits. Are we now seeing a change with Chipping Sparrows?

Another option is an external microphone. At the recommendation of Joseph
Tuttle who led a DFO field trip to Park County in April, I purchased an
external microphone for my mobile phone. On Amazon, it was all of $15. It
clips onto my ballcap so my phone can remain in my pocket while Merlin
listens. This leaves my hands free to use binoculars and I can reach for
my phone to see what Merlin has heard. The external mic is MUCH better
than the built in mic.
Does anyone else have experience they can share regarding an external mic
for your phone?
Best Regards,

I tested Merlin several times while on a walk this morning. It consistently identified a Yellow-breasted Chat as a Lesser Goldfinch when I was more than 50 m from the bird! As I got closer, it changed its identification to chat.

Hello Paula!
Thanks for bringing this up--as a musician who's messed around with testing the accuracy of Merlin's audio identification (I can't afford a camera, so I've gravitated towards recording bird songs for the past few years haha), the proximity to the singing bird affects two incredibly important factors that influence the computer: clarity of timbre (specificity, density on sonogram, etc.) and decibels (imagine looking at a photo that has contrast blasted vs. a very low contrast-res image). Since many passerines are distinguished by mere nuances of timbre at times, *and* considering the constantly fluctuating factor of background noise that pollutes the clarity of the timbres Merlin can capture with a live sonogram, I've learned to give Merlin audio an appropriate amount of skepticism. Merline audio will continue to improve with time, but the volume of audios captured in the birding community is so enormously dwarfed by the photos captured, so training Merlin has disproportionately favored photos over audio as of now!
Happy birding! Caleb Alons

** Caution: EXTERNAL Sender **
I had Merlin identify a bird as an Indigo Bunting when the only bird singing was a Lazuli Bunting - clearly in my binoculars - white wing bars and orange breast - maybe 50 ft from me. Merlin did finally identify the bird as a Lazuli, but more often came back with Indigo. I won't trust Merlin unless I hear the bird, and if the song is unfamiliar to me - I'll often disregard the ID ( not included in my ebird list) unless I SEE the bird. It's a Great tool - but is imperfect. .

Remain vigilant when using Merlin.

I tested Merlin several times while on a walk this morning. It consistently identified a Yellow-breasted Chat as a Lesser Goldfinch when I was more than 50 m from the bird! As I got closer, it changed its identification to chat.

I agree Marty,
Think about the number of photos that are probably submitted daily. 100K or 1M? Worldwide.
I’m sure there are far fewer sounds submitted. When the sound reviews increase to a similar level and frequency then our sounds quality will increase too.

There's good reason not to rely solely on Merlin Sound ID, or sometimes, even your ears! (After all, Merlin WAS a magician, and although it's called "Sound ID", it labels what it lists as "best suggestions", not identifications.) While I was in Portal, AZ in April, a Northern Mockingbird flew in and perched in a nearby mesquite. I had Merlin Sound ID running, and as I watched the mockingbird, it proceeded to mimic all of the following (as "suggested" by Merlin, and my ears, too!): Northern Flicker, Cactus Wren, Brown-crested Flycatcher, Say's Phoebe, Rock Wren, Gila Woodpecker, Hooded Oriole, Western Kingbird, Western Tanager, Ash-throated Flycatcher, Hermit Thrush, Crissal Thrasher, & Brown Thrasher, with some of those repeated/interspersed in the sequence!

Date: 6/20/25 11:42 am From: Pauli Driver-Smith <hollyhockfarms...> Subject: Re: [cobirds] Different bird at my deck last evening
Another question. Now that we think that it is a Blackburnian Warbler, what do they eat? I still have a bid feeder out filled with niger seed for the gold finches, and a pie plate filled with treats such as slightly ripe strawberries, blueberries, cherry tomatoes, etc. Was it attracted to any of that?
I'm going to keep an eye out for it and if I see it again, I'll notify the list.
By the way, the Yellow headed blackbirds are especially abundant on the south end of Highland Lake this year, and I was able to see my first fledglings. They almost look like chicks that have started to feather out a bit.

Subject: Re: [cobirds] Different bird at my deck last evening
I think it is too small. It was somewhere in size between a goldfinch and a House sparrow. I got a good look at its size because it landed right at my feet, then flew up into the tree next to my chair, sat there for a second, then flew off into the other trees. It looked like a Warbler in body size and shape but which kind, I'm not sure of. The closest it comes to in my bird book is a Blackburne Warbler, but I didn't think they came this far south.

It looks like a warbler. right size, beak and body shape, etc. What is different is that it had an orange throat that bled down into his chest, dark brown/almost black body, white wing patches/bars` and a bit of a black cap that stretched down to his back. The orange was really orange until it reached his chest then blended into more of a yellowish tint. If it was a lot bigger, I'd say it resembled some Orioles in coloring.

I haven't seen it again, but if it is still around, I'll keep an eye out. I have about 60+ trees on my property across from Highland Lake. They are very birdy this year, but until last evening, nothing unexpected.

Hi Pauli,
At least part of your description sounds like a Blackburnian warbler.
I had a small bird fly down at my feet last evening then take off into the trees. I got a fairly good look at it, and I know for sure that it is one I have never seen before. It took off again before I could get a picture.

As Mary says, it's certainly possible.
We had a rather celebrated Blackburnian five years ago at the "migrant
trap" that is the First Creek @ Green Valley Ranch hotspot in Denver.
The male bird stuck around for five days in mid-May 2020 and became a lifer
for many birders.

I think it is too small. It was somewhere in size between a goldfinch and a House sparrow. I got a good look at its size because it landed right at my feet, then flew up into the tree next to my chair, sat there for a second, then flew off into the other trees. It looked like a Warbler in body size and shape but which kind, I'm not sure of. The closest it comes to in my bird book is a Blackburne Warbler, but I didn't think they came this far south.

Sounds like the gull was present early this morning at South Shore Marina at Pueblo Reservoir, Pueblo County, 20 June. Good luck to everyone trying to see it today and this weekend. I won't be around there today or tomorrow, family things going on. It was nice to see so many birding friends yesterday afternoon at Pueblo Reservoir. Congrats to Mark Peterson on another amazing find for Colorado.

In the past few days, two extremely rare birds have been found in SE Colorado.
The Cactus Wren is the 3rd state record. https://cobrc.org/Reports/SpeciesDetail.aspx?id=509 The first was in a Colorado Springs back yard in late March 2018, and the second was in late March last year in Otero Co.
The Brown Booby is the 2nd state record. The first was found in Left Hand Canyon, Boulder Co: https://cobrc.org/Reports/SpeciesDetail.aspx?id=504 The bird was taken to a rehabilitation center, but it died a little while later. Both these boobies were obviously seriously disorientated. If this bird is to survive, then it needs to quickly find a large reservoir such as Two Buttes reservoir to the NE or, possibly, John Martin reservoir some way to the N.
Cheers, Peter Gent. Chairman CBRC, Boulder.

Congrats to Joey and Nathan for locating a Cactus Wren. I remember the wren was first glimpsed about 40 years ago by Harold Holt and we all thought at the time he had gone nuts for making that call. So cincere apologies to Harold, where ever he may be.

The Cactus Wren found yesterday by Joey Kellner continues at the corner of CR 193.5 north of Kim in Las Animas County (37.636408,-103.431881). I heard the bird sing from due east of the corner six or seven times at about 5:20 this morning and got an audio recording. It sounded like it was within 100 yards of the road but I couldn't see it. It then sounded like it moved farther east. I suspect the corner is near the west end of its area. Other people have arrived to search for the bird so hopefully they will manage to locate it. I searched the spot from 7:00 pm to sunset last night without any success.
Be advised that the mockingbird that sings persistently south of the corner has picked up some Cactus Wren song and can cause momentary confusion.

Date: 6/13/25 10:46 am From: 'Andrews Robert' via Colorado Birds <cobirds...> Subject: [cobirds] Prothonotary Warbler at Cherry Creek State Park, Arapahoe Co.
Hello all,
The gorgeous Prothonotary Warbler at Cherry Creek State Park, Arapahoe Co. continues near the footbridge adjacent to the Prairie Loop. The bird sings persistently, and moves around among the various trees, usually east of the bridge but sometimes to the west. It often stays well within the leaves as it forages. At times it will remain on the same perch for up to several minutes as it sings or preens, and sometimes comes out into the open. It tends to forage and sing from the middle level of the trees, but at times goes lower or higher. It was also seen investigating a hole low down in the trunk of a tree next to the footbridge, going in and out of the hole several times. This eBird submission includes photos (one also included below) and an audio recording of the song; the song comes at the beginning, at 15 seconds, 30 seconds, and 45 seconds into the recording. Thanks to those who discovered this bird on Thursday.

Just a note: This is the first year I have NOT had a resident Black-chinned Hummingbird in my yard since I have been putting out feeders, probably about 18 or more years. There was a male BCHU visiting briefly for two days in May, but hasn't been seen since. Hopefully, things will change as the summer approaches and I will have a resident and other hummingbird visitors.

Linda is likely correct that the many excellent presentations weren't
recorded. (Although in this day and age, who knows! Did YOU accidentally
press "record" on your smartphone? Hmm?)
Anyhow, I am happy to report that there is indeed to be published a nice
wrap-up of the entire symposium. This will appear in the next issue of
*Colorado
Birds*, the journal of the Colorado Field Ornithologists (CFO); all the
accepted abstracts will appear in full, and there will be a brief summary
of symposium highlights—and even some dramatic action photos from Kelsey
Crona's presentation. If that's not an inducement to hurry up and re-up
your CFO membership, I don't know what is.

Date: 6/11/25 1:51 pm From: Peter Gent <gent...> Subject: [cobirds] New World Bird List
All,
Steve Stachowiak alerted me earlier today that a new list of the world's bird species has been released today: see https://www.avilist.org/about/
This is a multi year effort to combine the 4 or 5 previous lists into a single list that everyone can agree on. This combines the previous lists of the IOC, ebird/Clements and the American Ornithological Society. The total number of species is 11,131. For example, this list splits the Herring Gull into the four species that last year were recognized in the ebird/Clements list but not in the AOS list.
At this point I have not had enough time to find whether this new list changes the birds that have been seen in Colorado or their common English names, but my initial thought is that it will not. For example, only the American Herring Gull has been documented in CO, and the other 3 splits have not.
Cheers, Peter Gent. Chairman CBRC.

I just received notice from my friend Dr. David Steingraeber, recently retired botany prof at CSU and noted Fort Collins birder (currently spending good portions of the year with his wife Carol in a rented casita in Portal, AZ), that we have a celebrity in our midst.
Dr. Kristen Ruegg of Colorado State University is the recipient of the William Brewster Memorial Award, presented by the American Ornithological Society to the author of the most meritorious body of work on birds of the Western Hemisphere published during the past ten years. Her research involves using feathers and high-powered chemistry to sleuth the migratory pathways of birds.

Subject: [cobirds] Orchard Oriole Mania
Hi all,
This is a long-overdue report, but I wanted to share an incredible phenomenon that Will Anderson, Nathan Pieplow, and I observed in Hale, Colorado this May.
On May 24th we arrived early to the Hale Crossroads eBird hotspot in hopes of finding some late season migrants. It was a cold day barely reaching over 50 degrees, with intermittent sprinkles, and fog. We had a fairly active morning, turning up good numbers of Swainson’s Thrushes, a few silent Traill’s Flycatchers, a Veery, Northern Waterthrush, some Yellow Billed Cuckoos, and even a singing male Hooded Warbler, but these are not the topic of this post.
Oftentimes it seems as though a visit to any open location with trees in the far eastern part of the state is likely to turn up Orchard Orioles, and today was no exception. Most parts of the property hosted a few singing males and small flocks, but we weren’t prepared for what we were about to witness. As we walked along the county road back to our cars, heading to our next location, we noticed a small flock of 6–8 passerines flitting around a modestly sized tree, what species I cannot remember. While we were trying to get an angle to identify them, suddenly, 10 Orchard Orioles flew out from the tree, crossed the road, and vanished into the forest—an impressive sight on its own. However it did not stop there, one by one Orchard Orioles kept flying out, first it totaled 20, then 30, then 40, 50, 60 not stopping until we had seen 96 Orchard Orioles fly out of the single tree. As we continued down the road, we began to see and hear even more Orchard Orioles scattered about that we hadn’t yet counted. By the end of our visit we had determined that we had come across approximately 145 orchard Orioles at the property. The previous state high count for this species on eBird was in the 70s, recorded by Steve Mlodinow, an impressive total in its own right!
I don't really have any conclusion to this story as this was likely the result of a weather-induced fallout, but I wanted to share the experience nonetheless. If anyone else has noticed anything like this anywhere else with this particular species I’d love to hear about it.

There is a convergence zone just to the south of Hale, CO in that wind
field. This is possibly in the wrong spot due to resolution issues in the
GFS (ask about it some other time if you are interested). What I believe
is going on with the 850mb winds is accurate, just slightly imprecise. The
convergence zone should be slightly further north. And if that is the
case, then Hale would be a good epicenter for where there should be a ton
of birds getting funneled into.
Jumping back a few hours:
https://earth.nullschool.net/#2025/05/24/1100Z/wind/isobaric/850hPa/<orthographic...>,36.58,2053/<loc...>,39.631 (5am May 24th), you can see that the same situation was there and the
convergence line was much more in line with Hale. Everything in the orange
outline (hand drawn, so not super accurate), should end up in the area
around Hale and if this happened for multiple hours, then you have a really
crazy good situation to get LOTS of birds in one place.
[image: Screenshot 2025-06-10 at 11.37.13.png]
So this was a great time of year for Orchard Oriole migration, a great
weather situation to get the birds to Hale, great idea to go birding out on
the eastern Plains, and probably some luck to be at the right place at
the right time. Congrats!

Hey, all.
Shortly after Hannah Floyd and I got in yesterday evening, Sun., June 8,
from the most excellent Colorado Field Ornithologists (CFO) annual meeting
in Grand Junction, I took a quick walk down to Greenlee Wildlife Preserve,
Lafayette, Boulder Co., and what did I hear in the tall shade trees near
the intersection of Salina & South Fork but a *great crested flycatcher.*
It's ironic: On the CFO field trip to the Colorado National Monument that
Hannah and I and Cary Atwood led earlier in the day yesterday, we all got
to enjoy ash-throated flycatchers, in the same genus as the great crested
flycatcher, aplenty, and we talked about how, while it's nice to look at
*Myiarchus* flycatchers, nothing beats listening to them.
Then, this Mon. morning, June 9, whilst settling down at the desk, what
should I hear in the big ole shade tree out front but a great crested
flycatcher. This time, I had the phone nearby, so I pointed it out the open
window and got a perfectly diagnostic spectrogram of the flycatcher's
spectrographically unique call:
[image: GCFL.png]
Note the tripartite spectrographic signature, unmistakably recalling the
insignia of the Klingon Empire:
1–a steadily rising whistle through the 2K band. 2–a sharp spike from 3K to
5K. 3–a whistle falling fairly fast through the 2K band. These three
elements create the *wheeEEP!* mnemonic known to any birder who's ever
wandered the Eastern broadleaf forest in summer.
Another irony. Or good timing. Or something. Remember that guy's
presentation at the Sat., June 7, afternoon science session at the CFO
annual meeting? ;-)
tl; dr– Just press the red button on your phone, make a quick-and-dirty
sound spectrogram, and it's off to the races.
As to seeing the bird, good luck with that. I caught the briefest glimpse
of a largish bird in the treetops, a plausible *Myiarchus*. Based on my
encounters yesterday evening and this morning, I would say that it calls
for a few minutes at a time, then falls silent. Pretty typical of great
crested flycatchers in my experience. I guess you could walk up and down
South Fork Dr., especially around the intersection with Salina St. And I
wouldn't be surprised at all if the bird makes its way down to the preserve
proper; it's nicer down there anyhow. ;-)
If you stay in the neighborhood, be mindful of, and respectful toward, the
gendarmes and, much more so, the punctilious HOA inspectors, who patrol the
mean streets of the subdivision looking to write up citations for the
little girls drawing blue unicorns and pink fairies with water-soluble

There are 4 parking areas for Ranch Ponds.

I helped make up the bird list years ago when I lived next to the park. If

Did you tell the people at the Visitor’s Center? There is a chalkboard
where people write down rare and interesting sightings. The park
naturalist would be interested such a rare sighting. I wrote down my
catbird.

Hello all,
Curtis Higgins, Lindsay Purifoy and I were out near the edge of Golden Gate Canyon SP today and heard and subsequently spotted a male Hermit Warbler in a conifer-lined gully east of the pond at 39.843, -105.363.
Depending on if you have a State Park pass or a SWA/Fishing/Hunting license you can park in either the SP parking for Ranch Ponds and walk over the creek and east (left) until you pass the pond and turn right up the trail that branches off up the draw. If you park at the SWA lot you go right down the trail and take the 2nd trail on the left.
The bird was singing quite a bit, even at midday, as it moved around the area.
Hope that others can enjoy!

Date: 6/7/25 2:08 pm From: John Tumasonis <snakemonev...> Subject: [cobirds] Sandhill Crane and Orchard Orioles - Adams County
All: Saturday June 7th, 2025, at Adams County Fairgrounds \ Riverdale Regional Park and the trail adjoining the Platte River. It baffles me why few birders and naturalists ever visit this area. It has one of the highest concentrations of Bullock's Orioles along the Front Range, along with good numbers of yellow warblers, warbling vireos, pelicans, cormorants, herons, egrets, raptors, and kingbirds. I normally park near the restroom on Campground Road and walk due east to the Platte River bikeway just north along Mann Nyholt Lake, crossing the footbridge to get near the river.
Note: there is a lot of construction going on and a road detour is necessary on a dirt road. It's not bad, if you take it slow - passenger car safe.
List: *SANDHILL CRANE* - good looks of it flying low over Mann Nyholt Lake and the adjoining fishing lake. Flying to the North. Adult. Will someone please tell me what a sandhill crane is doing in Adams County in June? American White Pelican - at least 40 - adults and juveniles - in lakes, ponds, on the river and flying Double Crested Cormorant - 30+ in river, ponds, lakes, and flying Canada Goose - 50 - in the river and flying Mallard - 30+ - males and females, mostly along the river Great Blue Heron - 2 - foraging on the river Snowy Egret - 6 - foraging along lakesides Red Tailed Hawk - 1 - flying, the only raptor seen today Eurasian Collared Dove - only 1 Mourning Dove - over 30 - foraging on the ground, and perching in trees Belted Kingfisher - 1- flying along the river Northern Flicker - 7 - most concentrated near the river Western Kingbird - 12 - fights, chases Eastern Kingbird - 4 Western Wood Pewee - 3 - all heard near the river Warbling Vireo - 12 - concentrated in specific areas along the river Blue Jay - 4 Cliff Swallow - hundreds, some gathering mud, others nesting under bridges Barn Swallow - 40 - throughout the area gathering insects Black Capped Chickadee - 3 - only a few heard House Wrens - 35 - high concentrations by the river underbrush and trees American Robin - 60+ Feeding nestlings, foraging, songs, calls, fledglings Gray Catbird - 4 - songs along the river brush land European Starling - 30 or more - many fledglings Yellow Warbler - 20+ Most seen and heard along the river in cottonwoods, willows, and locust trees. Bullock's Oriole was aggressively attacking one. Yellow Breasted Chat - only 2 heard Song Sparrow - 8 - singing along the river Lark Sparrow - 3 - foraging on the ground Western Meadowlark - 1 singing on adjoining golf course Red Winged Blackbird - 100+ along ponds, lakes, and the river; aggressively attacking other birds Common Grackle - 40+ Brown Headed Cowbird - only 2 males Bullock's Oriole - 20+ mature males, females, and 1st spring males. Carrying nesting materials, some nests already fully built, chasing other birds, songs *Orchard Oriole* - 2 males singing. Two separate individuals, both singing on exposed cottonwood tree branches - easy to see. The first was by the footbridge near Mann Nyholt Lake, near the river (seems to have established a territory). The 2nd male was about 1 further north at the end of the Frisbee Golf Range singing in big cottonwood tree. House Finch - 6 - only a few American Goldfinch - 4 House Sparrow - 2 (unusually scant)
Note: one big cottonwood tree had the following birds in it: an Orchard Oriole, 2 Bullock's Orioles, 2 Robins, 1 Eastern Kingbird, 2 Westing Kingbirds, 1 Yellow Warbler, 2 Grackles, 1 Flicker, 1 Red Winged Blackbirds and 1 House Wren - I want that tree form my backyard!
I don't know how prevalent Orchard Orioles are in this area, but I don't remember seeing any there last year at this time.
Happy Birding, John T (Tumasonis) "I'm not a real birder. I only pretend to be one on CoBirds."

Birders,
The second-year dark phase Reddish Egret I reported at Adobe Creek Reservoir (Blue Lake) on May 20th was present in the exact same location today, so it appears to be hanging around. Today, it was in the shallow bay about 1/2 mile north of the outlet gates, on the west side of the outlet canal. From Bent County Road 10, drive west on Road UU to the dam, and park below the dam just past the cattle guard. From there, walk north to the bay.

All,
The Anhinga is again being seen along 95th Street in Boulder about 200 yds north of Boulder Creek. This is the 4th confirmed record of this species in CO.
The first two are specimens collected in 1927 and 1931. The third was seen at Barr Lake in 2003. This is the first sighting where many birders have got to see this species in the state. You're welcome to submit reports of this bird, and other rare birds seen around the state this spring, at https://cobrc.org/
Thanks, Peter Gent. Chairman CBRC.

I need to revisit my statement from earlier tonight that the *Swainson
thrush* flight this Tues. evening, June 3, isn't East Coast–like in its
intensity. Because right now (11:35pm MDT) it's like that. I'm hearing 5+
flight calls per minute. If you're an insomniac or for whatever other
reason awake right now, go outside and listen. It's really something.
It's not lost on me that it's cool that the strongest spring night flight
I've heard in quite some time here in Lafayette is happening well into the
first week of June. Migration isn't over.

Hey, all.
*Swainson thrushes* are migrating over Lafayette, eastern Boulder Co.,
right now in the fine mist. Lovely to hear their little whistles in the
darkness. Not a massive East Coast–style flight, but one or two per minute.
Also a resident *common nighthawk* or two.
A few other odds and ends:
Yesterday, Mon., June 2, at Murphy's Pasture & environs, Pawnee National
Grassland, Weld Co., Hannah Floyd and I found many *grasshopper,
Cassin,* & *Brewer
sparrows.* Great encounters, too, with a greater short-horned lizard and a
prairie rattlesnake. We missed the funnel cloud directly over Briggsdale;
we left too early.
And back on Sun., June 1, along the Fowler Trail & environs above Eldorado
Springs, Boulder Co., Kieran Schnitzspahn, Hannah Floyd, Isabelle Busch,
Owen Robertson, Archer Silverman, and I found at least six *ovenbirds,*
along with the usual slug of *Hammond flycatchers, plumbeous vireos,
Virginia* & *MacGillivray warblers,* and *lazigo buntings.* Also, a *peregrine
falcon,* likely a resident.

Thank you Norm and Susan for your examples of Merlin being misused. For me, Merlin identified a coyote howl as a common loon, in the middle of a pinyon pine forest in Crestone, CO.
I agree it is a great tool and also agree it should never replace actual sound and visual IDs by live humans.

With nightjars, there's a thin line between faith and stubbornness.
Tonight, I was rewarded by whatever we want to call my ritual of looking at the darkening and too often empty sky during the last week of May and the first of June. Eight Common Nighthawks flew over, a good number for spring migration.
The first seven were in three groups (3 - 2 - 2) and flew moderately low and moderately directly northwest.
The eighth hung around over my west Centennial house, flying low loops, roughly at the level of the bats (Big Brown Bats, presumably?).

If you are using Merlin to identify birds by sound only without significant
experience with the songs and calls, you are likely making numerous
mistakes. I know of experienced birders with some amazing birds it
identifies that are simply not there. The other morning it identified
Plumbeous Vireo, Veery, Scarlet Tanager, and Summer Tanager within a few
minutes. For the latter two, it was using Robin calls. It would have been a
staggering number of new yard birds. In an Arvada park, I “tallied” Common
Loon (a cow}, Pygmy Nuthatch {no trees within 200 feet} and Red Crossbill.
Merlin is a great tool, but the frequency of misidentifications occurs very
often. It has identified Prairie Dogs as Savannah Sparrow and squirrels as
several things. A friend of mine had three first state records in his yard,
none of which existed. The phrase “identified by Merlin” are the three
scariest words my friends and I see on reports. If it “identifies” a rare
bird, you need to see it.
The King Rail at Chico Basin needs good recordings for me to believe it was
there. Nathan Pieplow made recordings of what others were calling the King
Rail and after analyzing them as a female Virginia Rail. Nathan is
excellent at doing this. There was a King Rail that was reported at John
Martin several years ago. He again made recordings and again it was a

There are never a ton of species here, but because of the side slope and scrub oak you are quite near the breeding birds ... plus it's a beautiful spot. Good chance to spend some time looking at markings and behavior (like Rock Wrens doing deep knee bends).
Every year the buntings, grosbeaks, wrens join a Yellow-Breasted Chat, Swifts, and Lark Sparrows in the oak and the cliffs. Wildflowers aren't spectacular this year but they are in full bloom now.

A few things to please be aware of while viewing the bird on Boulder Valley Farm:
-the ponds and surrounding farmland are closed to the public. The bird is perfectly visible from the road. -the sides of the road were recently seeded and are actively being restored after a large construction project. Please, please do not park on or trample this restoration site. -do not block ranch gates and be courteous to the ranch manager, John, if you see him. -there is an active Osprey nest a few hundred yards south of the Anhinga pond, close to the Boulder Creek bridge. Please give them space.
Happy chasing,

All the best birds are insectivores.
Weekly, I visit Eastern Phoebes along the High Line Canal Trail in Centennial / Greenwood Village. During my visit on 5/28, I also heard Western Flycatchers, my first of the year there. They've been nesting along the Canal and nearby Little Dry Creek since at least 2018. (The phoebes began nesting there last year, as far as I know.)
On May 30, nest-building Cliff Swallows were numerous at the Streets of Southglenn shopping center in Centennial. I've not previously seen them in high numbers at this outdoor mall. (Barn and Violet-green Swallows also nest there.)
On May 31, I had my first nighthawk sighting of the year. The bird flew directly north, with just a few flutters off its path to flycatch.

Date: 6/1/25 7:57 am From: meredith <meredithmcburney...> Subject: [cobirds] Chatfield Banding Station - Bird Conservancy of the Rockies 5/31/25
Our last day seemed like it should be the last day of monitoring spring migration. We banded only 8 birds plus caught 8 that had been previously caught this season. Only 2 of the 8 new birds and none of the recaps were for sure migrating through - a Swainson's Thrush and a MacGillivray's Warbler. A majority of the summer and year-round resident birds showed signs of breeding.
A few unofficial observations about the season (subject to change once data is finalized):
The first couple of weeks were dismal, well below normal, followed by a couple of fairly robust weeks. In the end, preliminary results show we are in the normal range for total birds caught. This was made possible, at least in part, by a banner year for Gray Catbirds, which this year are challenging Yellow Warblers for the most caught species title.
Flycatchers continue to be in short supply. Swainson's Thrush numbers are up, but there were very few Hermit Thrushes.
Here are the 8 new birds banded on our final day of the season:
Thanks as always to the loyal crew of volunteers who make it possible to efficiently run a banding station that monitors birds while sharing information with school groups and/or the general public every day of the season. You tolerate the slow days and step up when it gets busy. This season you also got to protect the birds from a persistent bobcat (who had to be chased off almost every day), a snapping turtle (who chose to lay her eggs directly under net 26), numerous deer (who are not interested in the birds but seem to enjoy destroying nets), and rumors of a fox prowling around net 22.
Thanks also to all you who care deeply about birds. I have e-mails from several of you to which I have not yet responded; I will do so before heading off to the CFO conference at the end of this coming week!
Until next season,

Subject: [cobirds] Leucistic Blue Grosbeak?
I attached two photos of what looks to me to be a leucistic Blue Grosbeak. Prior to sending this email, I consulted with ChatGPT on what she thinks. Does AI make sense for birding questions?
"This bird does appear to be a Blue Grosbeak (Passerina caerulea), but with highly unusual coloration.
Here’s what stands out:
* The bird has typical Blue Grosbeak structure: large, conical bill; stocky body; and thick dark feathering.
* It shows blue patches on the face and underparts, which is consistent with a male Blue Grosbeak.
* However, the rest of the plumage is much duller or brownish-tan rather than the vibrant deep blue typical of a fully mature male. The wings show strong contrast but not the usual rich rufous wingbars.
* The coloration appears patchy, suggesting an abnormal pigment condition.
Likely Explanation:
This is probably a partially leucistic Blue Grosbeak or a hybrid/variant with an unusual molt or feather pigmentation issue. Leucism can cause irregular patches of normal and pale coloration, and that’s consistent with what’s seen here. It’s not a textbook leucistic example (which usually has much more white or pale), but leucism manifests in a wide range.
Alternatively, this could be:
* A young male molting into adult plumage (but the bill and body size suggest full maturity).
* A diet or health-related pigment disorder during feather development.
Summary:
Yes, this is very likely a Blue Grosbeak with an unusual pigmentation condition—probably a mild or irregular case of leucism. It’s a rare but documented phenomenon in many bird species.
