Snowy OwlBubo scandiacus
A large, powerful owl of the high Arctic tundra, colored for camouflage during northern winters. In summer it may be nomadic, concentrating and nesting where there are high populations of the small rodents called lemmings. At other times it takes a wide variety of prey, including birds as big as geese. During some winters, large numbers of Snowy Owls appear south of the Canadian border; those that stop in towns and cities invariably cause a stir and attract media attention.
