White-breasted Nuthatch is associated with mature oak forest in the East, southern Arizona, and the West coast, but it pine forests in much of the Interior West. Most remain in pairs year round.
Difference in habitats preference, plumage, measurements, and calls among subspecies lead some to suspect they might represent separate species.
Nuthatches are often spotted moving up and down on the trunks and limbs of the tree. They eat both seeds, for which they have earned the name “nuthatch”, and insects.
VOICE Song a nasas, drawn-out series of wi or yeh notes. Calls vary from a clear, nasal yank (eastern nominate subspecies), to a higher beerb (Pacific aculeata), to a rapid series of call notes.
