[cobirds] RMBO Chatfield Banding Station Report, 5/30/12

The upside of this early spring for plant life is that we are getting to experience early breeding among at least some bird species – today we caught 7 female Yellow Warblers (all caught previously this season) with brood patches.  I went back through our old records, and found a few late May YEWA brood patches (from 06, 07, and 08) but nothing like this.  If we’ve caught 7 today, how many breeding YEWAs must there be in the banding station area?!

 

Only 9 new birds banded today…..

 

House Wren       1

Gray Catbird       1

Cedar Waxwing                2 (They have been in the area for 4 days now; catching a couple every day…..)

Yellow Warbler 2

Lincoln’s Sparrow             1

Brown-headed Cowbird               1

American Goldfinch        1

 

Open through Sunday.
