You normally see these scurrying up trees, always very active, they seem to be always on the go. A quick glimpse might mistakenly make you think that you have seen a mouse running up a tree. Here is one sitting still for a change.
Wow, a lot like a wren in the face. I don't think we have this one. Looks a lot like our Carolina wren, but not the spots. I do love birds when they scurry trees!
