[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.
