Winters north to southern Alaska, Idaho, Kansas, Kentucky, and Maryland. Preferred nesting habitats include dense brush near open grasslands. During winter, occurs in open woods and gardens.
The White-crowned Sparrow is one of the best-studied songbirds in North America. Much of our knowledge of bird song and development is based on studies of this species.
Because males 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.
Four of the five subspecies are migratory. The sedentary race lives in a very narrow band along the California coast.
A group of sparrows has many collective nouns, including a "crew", "flutter", "meinie", "quarrel", and "ubiquity" of sparrows.
The White-crowned Sparrow is a medium-sized sparrow which is found in North America. Preferred breeding habitats of the species include brushlands found in northern Canada and the western United States. Nests are built in low bushes or on the ground, camouflaged by low vegetation. Northern populations will migrate in winter months to the southern United States. They are rarely occurring in western Europe. Food is found on the ground or gleaned from bushes. Flying insects may be caught mid-flight, but diets consist mainly of seeds, vegetation and other insects. The conservation rating for the White-crowned Sparrow is Least Concern.
