A hunter in winter white
Don't be fooled by the snowy owl's sleepy looks.

Unlike other owls that prefer to hunt at night , the snowy owl
is active in the daytime.
Description: The Snowy Owl is a large, diurnal white Owl that has a rounded head, yellow eyes and black bill. The feet are heavily feathered. A distinctive white Owl, their overall plumage is variably barred or speckled with thin, black, horizontal bars or spots. Females and juveniles are more heavily marked than males - adult males may be almost pure white, although they have up to three tail bands. Adult females are distinctly barred throughout, and have from four to six tail bands. Immatures are very heavily barred throughout, and dark spotting may codominate or dominate the overall plumage. Intensity of dark spotting varies with the sex of the immatures, females being the darkest. Juveniles are uniformly brown with scattered white tips of down.

Habits: Snowy Owls are active during the daytime, from dawn to dusk. They have a direct, strong, and steady flight with deliberate, powerful downstrokes and quick upstrokes. They make short flights, close to the ground, from perch to perch, and usually perches on the ground or a low post. During hot weather, they can thermoregulate by panting and spreading their wings. Snowy Owls are very aggressive when defending their nest.
Voice: The Snowy Owl is virtually silent during nonbreeding seasons. The typical call of the male is a loud, harsh, grating bark, while the female has a similar higher pitched call. During the breeding season males have a loud, booming "hoo, hoo" given as a territorial advertisement or mating call. Females rarely hoot. Its attack call is a guttural "krufff-guh-guh-guk". When excited it may emit a loud "hooo-uh, hooo-uh, hooo-uh, wuh-wuh-wuh". Other sounds are dog-like barks, rattling cackles, shrieks, hissing, and bill-snapping.
Nestlings "cheep" up to 2 weeks of age, then hiss and squeal.
Hunting & Food: Most hunting is done in the "sit and wait" style. These Owls are highly diurnal, although they may hunt at night as well. Prey are captured on the ground, in the air, or snatched off the surface of water bodies. When taking snowshoe hares, a Snowy Owl will sink its talons into the back and backflap until the hare is exhausted. The Owl will then breaks its neck with its beak. Snowy Owls have been known to raid traplines for trapped animals and bait, and will learn to follow traplines regularly. They also snatch fish with their talons. Small prey up to small hares are swallowed whole, while larger prey are carried away and torn into large chunks. Small young are fed boneless and furless pieces. Large prey are carried off in the Owl's talons, with prey like lemmings being carried in the beak.
Distribution: Circumpolar - Arctic regions of the old and new worlds.
In North America, Snowy Owls breed in the western Aleutian Islands, and from northern Alaska, northern Yukon, and Prince Patrick and northern Ellesmere islands south to coastal western Alaska, northern Mackenzie, southern Keewatin, extreme northeastern Manitoba, Southampton and Belcher islands, northern Quebec and northern Labrador. The Snowy Owl is highly nomadic. During periods of lemming and vole population crashes in the Arctic, or excessive cold and snow in winter, mass movements of Snowy Owls occur into southern Canada and
northern United States. These invasions occur every 3 to 5 years, but are highly irregular. Adult females stay furthest north while immature males move furthest south during these incursions.
