[cobirds] Blackburnian Warbler Barr Lake Adams Co.
September 1st. A Blackburnian Warbler was spotted flitting around the banding station at Barr Lake State Park (Adams). It was with some Townsend's Warblers. Larger numbers than usual of Townsend's seem to be all over that area of Barr. If you see them, check for a Blackburnian Warbler too! I didn't believe my eyes, but I downloaded my pictures of the bird today! Susan Rosine Brighton -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Prewitt Res SWA (Washington Co)
Today I met Chuck Aid in the Washington County part of Prewitt Res SWA at 7:30 a.m. We birded the inlet canal, the reservoir, and the woods below the dam, all extensively. We saw a diverse 62 species, highlights were Sanderlings, 12 Marbled Godwits, Forster's, Black, and Common Terns, Peregrine Falcon, Common Nighthawk, 2 Olive-sided Flycatchers, 2 Dickcissels (Chuck), a couple Western Bluebirds, and 3 1st year Red-headed Woodpeckers (I hadn't seen young before, beautiful birds). Warblers were Wilson's (a ton), Orange-crowned, MacGillivrays, Yellow-rumped, 3 Townsend's, American Redstart, and Common Yellowthroat. 6 Blue-gray Gnatcatchers seemed like a high number. Lots of Chipping Sparrows, mostly young, same with Western Wood-Pewees, no White-crowned Sparrows yet, Orioles were gone, only 3 or 4 Western and no Eastern Kingbirds. Among hundreds of Baird's Sandpipers were no Semipalmated, Least, Spotted, or Solitary, only one plover (you know the one), and no Yellowlegs. Great day, high 80's and low 90's but lots of foraging activity all day long. Dan Stringer -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Barr Lake - Warblers and probable PHILADELPHIA VIREO - ADAMS County
I spent about 3 hours at Barr Lake today walking between the boat launch and below the dam in the riparian habitat. It was quite birdy in some areas. The large cottonwoods right at the boat launch area were very active first thing in the morning with Townsend's Warblers being the most abundant species. At one time I could see 7 in one tree! I estimated 25 TOWA in those trees alone (by far the most I personally had seen of this species at one time). Birds were actively flying between the trees and then down to feed on the sunflowers (either seeds or aphids, I'm not sure). A Black and White Warbler was also in those Cottonwoods. About 2/3 of the way down the trail towards the dam, is a field mostly filled with sunflowers, which had quite a few birds foraging. At this location, in fairly heavy cover, I had a bird that I believe was a Philadelphia Vireo, however it was moderately distant and I wasn't able to get my camera to focus on it at all due to the cover it was in, so I have left it on my checklist as WAVI/PHVI. Noticeable traits were dark lores and the yellow on the middle of the throat appeared brighter then the edges of the throat. I stayed in the area for 20 minutes hoping to get better looks and a photo or two, but it eventually flushed back towards the lake and I didn't see it again. Along the stream, below the dam, Wilson's Warblers were bouncing all over. A Tennessee Warbler was the best species I found below the dam. Despite much exposed shoreline, there was a noticeable lack of any shore birds (other than a few Killdeer) on this part of the lake today, but overall a very enjoyable morning. ebird checklist: https://ebird.org/checklist/S73106188 Cathy Sheeter Aurora, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Re: Boulder Reservoir closure
Hi Joyce, The sparrow doesn't appear to have been seen since the 31st in the morning. Personally, I've tried four times, but I guess now this is a nail in the coffin of this continueing rarity, which is unfortunate. The sparrow area appears to be closed because it's near the shore, however, Boulder Reservoir's website says the main north trail is still open. But on the hopeful side, due to the drainage, there is potential for a large number of shorebirds (which should we visible from the still open trail), maybe even some rarities!

[cobirds] Great egret - South Platte River Trail, Adams County
At 7:30 this morning, I saw a great egret in the Platte River directly adjacent to the blue and white water tank that sits about 0.75 miles south of 88th Ave. When I came back south, it was slowly working its way upstream.

[cobirds] Re: Empid ID help, please (Boulder County)
Hi Richard! Thanks for sharing this photo. I wanted to bring something new to this empid discussion: when differentiating between Dusky and Gray, note that Dusky Flycatcher will have a small, dark bill, but Gray Flycatcher has a much larger bill with an orange lower mandible. These two birds are remarkably similar in most other areas, and another mark that can be noted (but not used solely for differentiation due to typical variation) is that Dusky Flycatchers tend to have a rounded crown, whereas Gray Flycatchers tend to have a more flat-head appearance, which subtly alters each bird's GISS. *The birds are happy, and so am I* *~Caleb Alons, Larimer County* -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Re: Recorded Chip Call ID/Weld
Hi Gary! Hmm, this one's tricky. I think the reason xeno so highly recommends White-throated Sparrow is because the pitch, timbre, and attack are very good matches. However, the volume of the recording is relatively low, and the rhythm is a different. I'm not sure I would rule out Blue Grosbeak either, because that metallic chink note works. I think the best thing to do would be to upload the sonogram to ebird, and if the bird wasn't too distant (you can see the notes clearly enough), the shape should help confirm one way or the other. Interested to see what others think! *The birds are happy, and so am I* *~Caleb Alons, Larimer County* -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

[cobirds] Recorded Chip Call ID/Weld
Hi all I recorded this harsh chip call this morning about 6am in yard. Ran it through BirdNET to see what it thought and results were (1) White-throated Sparrow (doubt, would be new yard bird!); (2) Blue Grosbeak (probably and expected here) and (3) Northern Waterthrush (doubt, would be new yard bird!) Audio: https://www.xeno-canto.org/586018 Appreciate your confirmation help.
