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

[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

[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,

[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

[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

[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
