and because I'm bored...
Olive Warbler
Looks like it meets the description (and picture of the male) of a female Olive Warbler.
Hmm...could be it.
Is that you holding it? Is it a baby? Injured?
That's me holding him. He flew into a window in my mom's garage and was stunned for a few minutes. We snapped some pics and put him out in the yard and he flew away.
Look at the eye, the lack of striping on the wing and the dark cheek patch.
I still think its a femal Olive Warbler.
The beaks are very different.
Oh, and it was found in NC, not MD.
I emailed a guy I know at UM. Maybe he knows.
