Habitat Fairly common tundra-breeding species within its high Arctic range, although numbers vary considerably from year to year, influenced by abundance or available selection of prey. Outside breeding season, most birds move south, the extent to which they travel influenced by severity of winter weather and availability of prey.
Observation Tips Relatively easy to see if you visit its high Arctic breeding grounds in summer. In winter, most observations are by chance. Can turn up almost anywhere across Canada and northern U.S. in suitable habitatsóoften open grassland or coastal areas. In such situations, white plumage makes it easy to spot.
Range Alaska, Rocky Mountains, Great Lakes, Mid-Atlantic, California, New England, Plains, Southeast, Eastern Canada, Western Canada, Northwest
Voice Mostly silent, although territorial male sometimes utters series of deep hoots.
Discussion Huge and unmistakable species, which lacks "ear" tufts. Often active during the day, and obliged to be diurnal in Arctic breeding grounds by perpetual summer daylight. Even if resting or roosting, open nature of its favored habitats, and sheer size, make it relatively conspicuous. Feeds on lemmings and voles during summer months; diet in winter range is often more varied. Sexes are dissimilar.
