Yellow-rumped Warbler! We call them Butterbutts. This is the major warbler in winter months.I went on a camping trip earlier this week. I took pictures of many birds. I've been unable to identify one of them. I think it's a type of warbler but the markings don't really match any of the pictures in my field guide. It would help to know it was in the Hill Country in Central Texas.
Warning, the picture is HUGE!
