[cobirds] Chico Basin Ranch Banding Station Report- May 21, 2026-Bird Conservancy of the Rockies

The Banding station woods was loud with Western Kingbirds early but not much influx of birds until after 9:00 AM. We caught the Townsend's Solitaire that had been hanging out for the past 3 days in the area. More Bullock's Orioles, mainly the second-year males piled into the woods. Most were very fat so they are only stopping for the day and will not be here to breed.
Another Warbling Vireo was banded and the measurements were not such we could ID it to the Western or Eastern Warbling Vireo. 
All recaptured birds not breeding in the banding area increased their weight from their previous banding date. Just think if we had no birds how many insects and pests we would have! YAY birds!

47 New Banded Birds

[cobirds] Colorado birder Amelie Anderson named 2026 ABA Young Birder of the Year

Hey, all.

Here's a news story from a short while ago on Colorado birder Amelie Anderson, recently named 2026 American Birding Association Young Birder of the Year:

https://www.9news.com/article/life/jefferson-county-7th-grader-national-young-birder-of-the-year/73-94edbb2d-2f82-4a77-9a1b-bd40dc43cfdd

While I have everybody's attention, here's a fun pic of Amelie and her birding buds at The Arsenal, of course, back on Feb. 22, 2026.

[cobirds] Black-bellied Plover and Red-necked Phalarope at Cherry Creek State Park, Arapahoe Co.

Hello all,


An excellent day of birding at Cherry Creek State Park, Arapahoe County today with Cynthia Madsen and Dave Hill. We saw 17 species of shorebirds, which in my experience is a very good count for the park. Highlights were Black-bellied Plover and Red-necked Phalarope. There were two Black-bellied Plovers at Pelican Point, one in full breeding plumage. We made a count of 124 Red-necked Phalaropes. This count could be low as flocks of 10-50 birds were constantly moving around. They were seen mostly from the Prairie Loop west to the southeast corner of the Lake Loop. There were also astounding numbers of swallows, probably 1000 or more. They were everywhere, over the lake, along the shore, in the woods, and over the grasslands. They were mostly Barn, Cliff and Violet-green, with some Tree and a few Northern Rough-winged. Migrant passerine species (warblers, sparrows, etc.) were very few. Dave posted the full list to eBird.

Still not many birds as the day before but after 10:30 the banding woods was moving with birds. The sun did eventually come out fully after 11 AM. Anyway, those birding the woods after 11 AM were busy looking at the birds around. 
The Ovenbird was still singing near the banding building again today.
