Regional Differences

White-crowned Sparrows that breed along the Pacific Coast tend to have yellow bills and duller white head stripes. Birds that breed from Alaska to Hudson Bay tend to have orange bills and white or gray lores. Birds that breed east of Hudson Bay and in the Rockies tend to have pink bills with black lores that merge with the black head stripes.
