White-breasted Nuthatch holds still for a moment.
White-breasted Nuthatches are gray-blue on the back, with a frosty white face and underparts. The black or gray cap and neck frame the face and make it look like this bird is wearing a hood. The lower belly and under the tail are often chestnut.
I entered 2 of these nuthatches on my latest Project Feederwatch count, and 1 red-breasted.
