The ghostlike snowy owl has unmistakable white plumage that echoes its Arctic origins.

Reproduction

These large owls breed on the Arctic tundra, where females lay a clutch of 3 to 11 eggs. Clutch size depends upon the availability of food, and in particularly lean times a usually monogamous pair of owls may not breed at all. Parents are territorial and will defend their nests against all comers—even wolves.

White Coloring

Young owls, especially males, get whiter as they get older. Females are darker than males, with dusky spotting, and never become totally white. Some elderly males do become completely white, though many retain small flecks of dusky plumage.

Hunting and Diet

The snowy owl is a patient hunter that perches and waits to identify its prey before soaring off in pursuit. Snowy owls have keen eyesight and great hearing, which can help them find prey that is invisible under thick vegetation or snowcover. The owls deftly snatch their quarry with their sharp talons.

A snowy owl's preferred meal is lemmings—many lemmings. An adult may eat more than 1,600 lemmings a year, or three to five every day. The birds supplement their diet with rabbits, rodents, birds, and fish.

Migration

These magnificent owls sometimes remain year-round in their northern breeding grounds, but they are frequent migrants to Canada, the northern United States, Europe, and Asia. Lemming availability may determine the extent of southern migration, when owls take up summer residence on open fields, marshes, and beaches.
