White-breasted Nuthatch

Sitta carolinensis

Summary 2

White-breasted nuthatches (Sitta carolinensis) are small birds that can often be spotted climbing up and down the trunks of trees. Their long bills make them easy to identify. Their bills are nearly as long as their heads and are curved slightly upward. White-breasted nuthatches have black crowns on their heads, with white cheeks and white undersides. Their bellies have a slightly pinkish region towards the tail. A nuthatch's back is bluish-gray. Their wings and tails are a mixture of white, black, and bluish-gray. Males tend to be slightly more brightly colored than females, with the dark parts of their plumage being very dark and contrasting with their light plumage. Females are more grayish overall.

Outside of the breeding season, they form mixed-species flocks with oak titmice, oregon juncos, and chestnut-backed chickadees.
