Among the largest of the world's nuthatches, White-breasted nuthatches also are noteworthy for an extensive repertoire of unusual behaviors and habits.
Unlike most other North American passerines, White-breasted nuthatches maintain close pair bonds over most of the year. In spring, they cement their pair bond by exhibiting a variety of courtship displays. Elaborate display rituals also are used in antagonistic territorial interactions, and distraction displays are used to deter predators.
The White-breasted nuthatch is common in western Oregon lowlands. It is most abundant in southwestern interior valleys, with specimens from Salem to Jackson County. It occurs in oak and mixed forests, nut orchards, and suburban plantings in the Willamette Valley region.
