The white-breasted nuthatch [Sitta carolinensis] is a small songbird of the nuthatch family which breeds in old-growth woodland across much of temperate North America. It is a stocky bird, with a large head, short tail, powerful bill, and strong feet. The upperparts are pale blue-gray, and the face and underparts are white. It has a black cap and a chestnut lower belly. The nine subspecies differ mainly in the color of the body plumage.
Like other nuthatches, the white-breasted nuthatch forages for insects on trunks and branches, and is able to move head-first down trees. Seeds form a substantial part of its winter diet, as do acorns and hickory nuts that were stored by the bird in the fall.
