They are cute little guys. It's fun to watch them climbing up a tree passing a nuthatch going down the tree. Between the two of them, they scour the bark for bugs pretty effectively.
The tufted titmouse is the cutest bird we get around here, but they are very shy, and won't come to hand like their cousins the chickadees, nor have I managed to get a really good picture of them. What equipment are you and you GF using?
