Bird Conservancy of the Rockies - Chico Basin Ranch Banding Report 5/28

[Colin Woolley]

Today we had a fine morning, with a decent variety and pace of birds, never too busy but never empty-handed either. The continuing surprise was recapturing the Kentucky Warbler yet again, though this time with a higher fat score than previously and weighing in about 2 grams heavier than last week (~15% mass increase). The other surprise was a White-throated Sparrow, our first this season and the latest spring banding record for this species at Chico (all others were in first 2 weeks of May). Overall we banded 30 new birds and had 6 recaptures, of 19 species total:

Dusky Flycatcher - 1

Alder Flycatcher - 1

Western Kingbird - 1

Yellow Warbler - 2

American Redstart - 1
