Global Range
H - >2,500,000 square km (greater than 1,000,000 square miles) - H - Holarctic. BREEDS: north-central Alaska, northwestern and central Canada south to California, northern New Mexico, northern Nebraska, Minnesota, northern Ohio, western New York, Maine, Nova Scotia; Iceland, northern Eurasia, Aleutians south to southern Spain, northern Italy, southern Russia and northwestern China. WINTERS: in North America, mostly in the U.S., regularly to central Mexico and Antilles; also Hawaii; widely in Old World. In the U.S., the highest winter densities occur in western Texas, northern Utah, Kansas, Mississippi-Arkansas, and southeastern North Carolina; except for the latter, these are associated with national wildlife refuges (Root 1988).
