Snowy Owl

The Snowy Owl is a large owl of the typical owl family Strigidae. It is also known in North America as the Arctic Owl or the Great White Owl. This huge yellow-eyed white bird is unmistakable. It is 53-65 cm long with a 125-150 cm wingspan. The adult male is virtually pure white, but females and young birds have some dark scalloping; the young are heavily barred, and dark spotting may even predominate. Its thick plumage, heavily-feathered feet, and coloration render the Snowy Owl well-adapted for life north of the Arctic Circle. This powerful bird relies primarily on lemmings and other rodents for food, but at times when these prey are not available, or during the ptarmigan nesting period, they may switch to ptarmigan young. As opportunistic hunters, they feed on a wide variety of small mammals and birds, and will take advantage of larger prey, frequently following traplines to find food.
