[cobirds] Bird Conservancy of the Rockies - Barr Banding Station Report, 8/31/24

Despite the heat, we continue to post decent numbers, with Wilson's Warblers leading the way.  I will report on how our second week this year compares with the 5-year average second week tomorrow.  But I can already say that we have surpassed the 5-year average for Wilson's (although we are way behind for Yellow Warblers and House Wrens, two other very common species this time of year).  As I've mentioned before, the Wrens and Yellows that we catch at this time of year are mostly summer residents, while the Wilson's are migrating through.

We banded 32 birds today, plus we caught 13 birds that had been previously banded this season.  Here are the new ones:

Mourning Dove 1

 Traill's Flycatcher 1 (I have been asked about why we often use "Traills" as opposed to "Willow" Flycatcher.  The updated (2022) Pyle Guide, which is basically the bander's bible, provides a fairly complex measuring system for separating the two species Willow and Alder.  When we have time, we will apply the formula and do the separation, but often we don't.  We believe that most if not all of what we call Traill's are Willows, which is the  species most likely to be found here.)

House Wren 1

Yellow Warbler 2

Townsend's Warbler 3

Common Yellowthroat 1

Wilson's Warbler 21

Brewer's Sparrow 1

Song Sparrow 1

We are banding Tuesday through Sunday mornings (closed Mondays).  There is a public session most weekday mornings from 7:30-8:30, and three time slots on weekends, at 8, 9, and 10 a.m. There is a $7 fee and registration is required – click here to register!

Let me know if you have any questions,
