We banded 2 Gray Catbirds and a Black-and-white Warbler. One of the catbirds had undertail coverts that were missing some of the rusty coloring - not sure if some feathers had come out and there weren't enough to overlap or if the feathers were actually missing color.

The Black-and-white Warbler was born last year. Some of the wing feathers (to the right of the lower thumb) are duller than the fresher, blacker ones.

Next banding session: April 1, 2014. No Fooling! Nets go up between 7 and 7:30.
Interesting. I don't recall seeing the coverts on Catbirds that random. We go back into operation next Sunday!
ReplyDeleteI know, that's why the photo. Gray Catbirds are more challenging than I expected - AHYs with light mouths, ambiguous eye color, many birds with growth bars in the tail, no "standard" look to the undertail coverts.
