Black-and-white Warbler
Day 120 / 365
I too used to swinging upside down from the tree when I was young. But I think he has me beat. 🙂
Interesting Fact: Black-and-white Warblers have an extra-long hind claw and heavier legs than other wood-warblers, which help them hold onto and move around on bark. ( http://www.allaboutbirds.org/guide/Black-and-white_Warbler/lifehistory )
