The snowy owl, also called the Arctic owl and the great white owl, is one of the largest and heaviest species of owls, with a wingspan of 50-60 inches. They nest in the northern Alaskan, Canadian and Eurasian tundras and, depending on food supply, migrate farther south during winter.
Not only do the owls' white feathers act as camouflage in the Arctic, but the thick plumage, which even covers the birds' toes, also provides insulation from the cold. The owls' sharp eyesight and hearing help them hunt rodents and other prey hiding under vegetation or snow.
