Two days ago I spotted this warbler in my backyard. Unfortunately I wasn't able to get a good look at it, and this was the only photo I was able to get before it flew away. Can anyone identify it for me? When I first saw it, it was on the ground like a sparrow; and it frequently bobbed it's tail.
Thanks Axel and John for your help. I am curious what makes you think palm warbler and not perhaps a prairie warbler? I ask because according to information I've found prairie warblers also bob their tails and forage near the ground.
