Guide to Boreal Birds
Overview
This species is restricted to western North America where it breeds in the western boreal forest and winters along the Pacific coast from southern British Columbia to California and northern Baja. One or two of these sparrows often join winter flocks of White-crowned Sparrows. They live with the flock but feed more in the shelter of bushes and visit open lawns less often. Migration north begins in April and extends in May and birds begin arriving back on wintering grounds in September and October. Breeds in shrubby areas where forest and tundra zones intermingle, but the species breeding biology has been little-studied.
