The Red-breasted nuthatch is a happy, jolly little bird, quick and agile in its motions and seemingly always in a hurry to scramble over the branches. It is distinguished from other nuthatches by white eyebrows, black eyelines and cap, reddish breast, and nasal yank yank song. Although males have a blacker cap and redder breast than females, distinguishing sexes in the field is difficult. During winter, is can be observed foraging in mixed-species flocks with Chickadees, Brown creepers, Kinglets, Townsend's carblers, and Dark-eyed junkos.
The Red-breasted nuthatch breeds and winters throughout Oregon where conifer or mixed conifer-hardwood forests are present, including some urban areas. It winters in wooded areas from valley floors to timberline. Migratory individuals are encountered widely in areas where they do not breed.
