The Sibley Field Guide to Birds of Western North America by David Allen Sibley
  • Four of the five subspecies of White-crowned Sparrows are migratory. The sedentary race lives in a very narrow band along the California coast. The most widespread race, breeding across northern Canada and wintering in the eastern United States, is the least-studied and least well known of all the races.
  • A young male White-crowned Sparrow learns the basics of the song it will sing as an adult during the first two or three months of its life. It does not learn directly from its father, but rather from the generalized song environment of its natal neighborhood.
  • Because male White-crowned Sparrows learn the songs they grew up with and do not travel far from where they were raised, song dialects frequently form. Males on the edge of two dialects may be bilingual and able to sing both dialects.
