    Short General Description
    A medium-sized songbird.
    Migration
    true - true - true - In the Northwest Territories, adults began arriving on breeding grounds during the last week in May; remained until early September (Norment 1992).
    Non-migrant
    true
    Locally Migrant
    true
    Food Comments
    Feeds primarily on seeds of grasses and weeds (ragweed, pigweed, goosefoot, panicum, etc.). Also feeds on invertebrates, especially in the summer (ants, caterpillars, true bugs, beetles, spiders and snails). Forages on ground.
    Reproduction Comments
    At the northern end of the range in the Northwest Territories, most initiated nesting in the second or third week in June, after the breeding habitat was at least 60% snow free (Norment 1992). Clutch size is 2-5, often 4-5, rarely 6. Incubation, by the female, lasts 9-15 days (range-wide average is 12 days). Young are tended by both parents, leave nest in 9-11 days, fed to some degree for additional 25-30 days. May produce several broods annually on California coast (Petrinovich and Patterson 1983).
    Ecology Comments
    May form flocks in winter, up to about 10-20 in southeastern U.S., 30-50 in West. <br><br>A large proportion of eggs and nestlings may be lost to predators (e.g., garter snakes, ground squirrels) in even a stable population (Petrinovich and Patterson 1983, Morton et al. 1993). <br><br>Permanent resident birds (<i>nuttalli</i>) on West Coast maintain year-round territories.

    Global Range
    H - >2,500,000 square km (greater than 1,000,000 square miles) - H - Breeding range extends from northern Alaska to Labrador, south to southern California, Nevada, central Arizona, northern New Mexico, central Manitoba, southeastern Quebec, and Newfoundland. The five recognized subspecies are fairly distinct in their distributions, with very little overlap of breeding areas (Morton 2002). Subspecies <i>nuttalli </i>is a nonmigratory resident of coastal California; <i>pugetensis </i>breeds along the Pacific coast from northern California to southern British Columbia; <i>oriantha </i>breeds in the central western United States and the Sierra Nevada; <i>leucophrys </i>breeds across northern Quebec, Labrador, and Newfoundland; and <i>gambelii </i>breeds throughout Alaska east to northwestern Ontario and south to southcentral British Columbia (Dunn et al. 1995). <br><br>During the nonbreeding season, the species ranges casually to central and southcentral Alaska and occurs regularly from southern British Columbia, southeastern Washington, southern Idaho, Wyoming, Kansas, Missouri, Kentucky to western North Carolina, south to southern Baja California and southern mainland of Mexico, Gulf coast, and Cuba. Subspecies <i>pugetensis </i>winters along the Pacific coast from Washington to southern California; <i>oriantha</i> winters from the southern U.S. border to Baja California and southern Mexico; <i>leucophrys </i>winters in the eastern United States north to the Great Lakes and rarely in New England north to Massachusetts; and <i>gambelii </i>winters throughout the western United States and sparsely in the eastern United States (Dunn et al. 1995).
