  • Coastal southern California (San Francisco Bay to Santa Barbara Co.)

Habitat

Found in coniferous forests, especially of Douglas fir, and mixed and deciduous woodlands. Visits backyard feeders.

Behaviour

Breeding

It nests in cavities, using fur and hair from deer, rabbits or coyotes. The clutch consists of 5-8 eggs.
