I posted this image to the Gallery and said it was a hermit thrush. Now I'm wondering if it might be an ovenbird. I took the photo in early May in a wooded area in Croton, NY. There is no sign of a black stripe on the head, but it's possible that that's just because of the angle of the photo. I've gone ahead and added a 2nd, much blurrier photo, just in case it's helpful in nailing down a correct ID. Thanks for your opinions.
