Subject: [cobirds] Chico Basin Ranch Banding Station Report- May 7, 2026-Bird Conservancy of the Rockies
The Ranch received some much needed precipitation yesterday. None as great
as farther north but the birds were out looking for insects and seeds all
day yesterday.
Today we opened the nets later due to the temps. Birds were very active
once it warmed up. It was good to see that those we caught/banded were in
good condition. The Least Flycatcher was the lowest fat condition. I am
sure it had the toughest time yesterday finding food. Glad the temps are
nice today to let the birds feed and prepare for migration.

Eighteen bird species captured/banded including 6 warblers (if separate the
subspecies) and 5 sparrows. Harris's Sparrow and Canyon Towhee were a
highlight for me.
