American Redstart (Setophaga ruticilla)
On the thumbnail I could not see the bird. It is so little! What a cute photo you got. The only Redstarts I get photos of are blurry birds in the trees. :)
Thanks Chilly. Only get to see them on migration of course. Helps to have a stream/pond!
I actually just spotted this. What a beautiful little bird! I've never seen one so thanks for adding your pic.
