Snowy owls are native to Labrador above the tree line; winter visitor to Southern Labrador and the Island when food is scarce in the Arctic.
This winter visitor of southern Canada hangs out in open fields and on shorelines similar to the treeless tundra.
Breeds in Alaska and northernmost Canada. In winter Snowy Owls across continent south to northern United States, irregularly farther south. Snowy Owls breed north of treeline in Labrador.
The Snowy Owl likes small mammals for its diet. It eats arctic hares and ptarmigan, but its main food are lemmings. When the owl moves south because lemming populations are low they mainly eat meadow voles - up to 300 a month. Also rabbits, dead fish, rats and birds are eaten.
The owls' main threat is food shortage. Jaegers in the arctic are known to prey on their nests. There is a high mortality rate (up to 30%) of nestlings.
Up to 35 years in captivity, and in excess of 17 years in the wild.
The male is almost pure white. The female is marked with dark brown spots and is larger than the male. They have yellow eyes which can't move; to see they turn their head from side to side up to 270 degrees.
A snowy owl may lay up to 10 eggs when food is plenty and none at all when prey numbers such as the lemmings are low. The male provides her with food while she stays on the eggs to protect them and keep them warm.
Average weight of females (5 lbs)(2.3 kg) and males (4 lbs)(1.8 kg). Stands almost (1.6 ft)(Â½) metre tall, with a wingspan of (5 ft)(1.5 m).
