This yellow-eyed, black-beaked white bird is easily recognizable. It is 52–71 centimetres (20–28 in) long, with a 125–150 centimetres (49–59 in) wingspan. Also, these birds can weigh anywhere from 1.6 to 3 kilograms (3.5 to 6.6 lb). It is one of the largest species of owl and, in North America, is on average the heaviest owl species. 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 taloned feet, and colouration render the Snowy Owl well-adapted for life north of the Arctic Circle.
Generally North of the Arctic Circle
This bird is most probably a female, it came for a winter visit to Wisconsin, from its normal territory somewhere north of the Arctic Circle.
