White-crowned Sparrow Zonotrichia leucophrys

White-crowned Sparrow Zonotrichia leucophrys

There are several different races of the White-crowned Sparrow, breeding from northern Alaska to California. When the time comes to migrate, the northernmost races travel farthest; races with progressively more southern breeding ranges move shorter and shorter distances. Those that live near San Francisco hardly move at all.

Adult has bold black-and-white head pattern: crown white with broad black stripe; eyebrow white; eyeline black. Bill pink to yellow. Face, neck, and breast gray; back and wings streaked black and brown, with white wing bars. Immature has brown and buff head stripes.

Voice Song a series of whistles, repeated or followed by a trill; varies regionally. Call a chink or sect.

Habitat Forest edges, bogs, meadows, parks, and suburbs.

Range Breeds from N. and W. Alaska east to N. Quebec and south in the West to central California and N. New Mexico. Winters along Pacific from N. British Columbia to Baja California and through most of the South.
