[cobirds] Chico Basin Ranch Banding Station Report-Bird Conservancy of the Rockies-October 1, 2026

Yesterday was a rain day. The Ranch needed rain. Today was a nice day to be outside. As you would expect not a whole lot of diversity but still a surprise of a Yellow-breasted Chat.

Birders spotted a White-winged Dove hanging around the barn/corral area and a Broad-winged Hawk in the Olive grove.

25 New Banded Birds

Wilson's Warbler- 5

Ruby-crowned Kinglet- 8

Hermit Thrush- 8

American Goldfinch- 1

Lincoln's Sparrow- 1

Yellow-breasted Chat- 1

American Robin- 1

Tomorrow is the last day or banding and birding on the ranch for the year. Hoping for a good bird day. Please register online to visit the ranch tomorrow at www.aikenaudubon.com

Many thanks to all the volunteers who made this season a success! Thanks also to the birders who shared their knowledge of Colorado Birds.

Have a good day,

Julie Shieldcastle, Bander

Re: [cobirds] Kettles of Hawks - Jeffco - Lakewood

I saw a kettle of about 16-18 raptors, looked like mixed turkey vultures and buteos, over Castle Rock between 85 and US25 here in DougCo on Tuesday. I was driving so I unfortunately couldn't pause to ID, but it was exciting!

After seeing Ira's post, and being a mile away, I went for a walk. I had 2 Broad-winged up high with a kettle of turkey vultures. I saw mostly vultures. Sky watching sure beats doing work. This was on the fed center in Lakewood, JeffCo.

On the theme of kettling Buteos . . .
Yesterday in the late afternoon I spotted a flock of 6 Broad-winged Hawks pass right over my Ken Caryl (JeffCo) home, heading south. And this morning a kettle of 15 Broad-wingeds was moving south at Chatfield SP (Douglas) along the Platte south of Kingfisher Bridge. Prior to these observations, all of my occasional fall BWHA sightings in CO have been of singletons (all from September).

Birders,

At 10 am we were N bound on Kipling S of Alameda and Tammy spotted a kettle of at least 70 - 80 hawks just E of Kipling. 2 min later there was another of about 15 birds. She spotted a couple of TV's but the rest were buteos.

Too far east for Ajit to get them.

I've never seen that in Colorado before.

[cobirds] Mountains in the City - Evening Grosbeak in SW Denver

To continue the theme of mountain stuff showing up out in the plains, was working at home (Athmar neighborhood, SW Denver, Denver Co.) this morning (Thurs. 1Oct.’26) and heard the familiar calls of an EVENING GROSBEAK out our open window. Quickly found her, but didn’t see or hear any others which is weird in-and-of-itself. In addition to the grosbeak (which was the first here in 7 years), we have a couple of continuing MOUNTAIN CHICKADEEs (first in five years) and a WOODHOUSE’S SCRUB-JAY (guess not technically a mountain species) today so far. In the past week or so have also had Ruby-crowned Kinglets, Hermit Thrush, and a small flock of Pine Siskins, though the kinglets and thrush were likely migrants, but still “mountains…ish”.

So keep your eyes and ears open and please keep the mountain theme going, it’s going to be an interesting winter.

Good Birding,

Doug
