This is a classic pose for the Nuthatch
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. The nest is in a hole in a tree, and the breeding pair may smear insects around the entrance as a deterrent to squirrels. Adults and young may be killed by hawks, owls and snakes, and forest clearance may lead to local habitat loss, but this is a common species with no major conservation concerns over most of its range.
