White-crowned Sparrow (Zonotrichia leucophrys)
Photographed the White-crowned Sparrow on the deck feeding on sunflower seeds. My backyard in the City of Timmins Ontario Northeastern Ontario Canada
The handsome White-crown is a favorite not only of bird-watchers but of laboratory scientists. Much of what we know about the physiology of bird migration has been learned from laboratory experiments with this species. The northern, northwestern, and mountain subspecies of White-crowned Sparrows have slightly different head patterns and songs. Song dialects vary locally as well. In the Arctic, where the sun does not set during the breeding season, these sparrows sing all night long; however, White-crowns farther south, in the Pacific Northwest, also sing frequently during the dark May nights. In the East, these birds are much less numerous than White-throated Sparrows, but flocks of White-throats often contain a few of these slender, elegant birds. Much of their feeding is done on the ground but, like White-throats, they will respond to a squeaking noise made by an observer by popping up to the top of a bush.
Habitats used by White-crowned Sparrow differ remarkably across its breeding range. Necessary habitat features of breeding territories include grass, bare ground for foraging dense shrubs or small conifers thick enough to provide a roost and conceal a nest, standing or running water, and sometimes tall coniferous trees. There are a number of different subspecies of White-crowned Sparrow that differ in their migratory patterns and timing. This species is remarkably adaptable in its food preferences, taking seeds and arthropods from the ground and plants, and hawking insects from perches. Breeding habitat throughout Canada appears to be abundant and populations stable.
