Overview

The habit of creeping headfirst down a tree trunk, then stopping and looking around with head held out at a 90-degree angle, is characteristic of nuthatches. The White-breasted is an inquisitive, acrobatic bird, pausing occasionally to hang and hammer at a crack. Essentially nonmigratory, during the fall it stores food for winter in crevices behind loose tree bark. Pairs seem to remain together year-round, for the species may be found in twos even in the dead of winter. Although they often join mixed flocks of chickadees, woodpeckers, and kinglets roaming the winter woods, they tend to remain in their territories. They are familiar visitors to bird feeders.
