This little Black and White Warbler was in Grant Park. It was scampering up and down the tree trunk looking for dinner. It seemed like it was thinking "Uh-Oh! How did I get way up here? It's a long way down" when it looked down from this branch. At least that's what I'd be thinking.
As usual on Feathered Friends Friday, there are a few more pictures of this Black and White Warbler at my birdwatching blog.
