This snap shot is really bad, this little gal was really fast and landed maybe twice where I could see her. Of course she hid behind leaves most of the time. This tree is really drawing in the birds lately.
I had not seen this bird before, but she is a Yellow-rumped Warbler. Apparently the most common type of warbler in the US. To see more (and better) photos check out this great website that helps you idendify birds. http://identify.whatbird.com/obj/154/_/Yellow-rumped_Warbler.aspx
