11 July 2016 – Ruby-throated Hummingbird

I found a presumptive HY male Ruby-throated Hummingbird in the southwest alcove of the NRC today.  I left it in place for a removal trial.

I did not obtain photos of the bill showing corrugations.  Instead check out the single ruby gorget feather and concave tip to primary feather #6 as indications of a male.  The bird carried no fat.

6 July 2016 – no casualties

The SY male Indigo Bunting I found yesterday has been moved, but not removed:

Presumably, this was a human moving the carcass from in front of the entrance to a more secluded location.

5 July 2016 – Red-eyed Vireo and Indigo Bunting

Today I found a Red-eyed Vireo in the southwestern alcove and an Indigo Bunting at the main north entrance.

 

The Indigo Bunting was a second-year male with zero fat and an impressive contrast of old and new feathers. I left him in place for a removal trial.  The Red-eyed Vireo, an ASY female with a brood patch and no fat, is the first vireo I’ve ever recovered as a window-kill from the NRC.

3 July 2016 – no casualties

I was away and unable to keep track of casualties at the Noble Research Center from 6/22–7/2.  On my check today (7/3), the carcasses of Tufted Titmouse, House Finch, and Yellow-billed Cuckoo were all gone. (Actually, a cuckoo wing remains but it’s time to call the carcass as removed as it’s very unlikely to be noticed at this point.) The most conservative date to ascribe for the scavenging removal trial is 6/22 which gives unofficial removal times of 7 (titmouse), 17 (finch), and 32 (cuckoo) days.
