One of the heaviest of North American owls, the Snowy Owl Bubo scandiacus stands nearly half a metre tall, with a wingspan of almost 1.5 m.A dense layer of down, overlaid with thick feathering, insulates the Snowy Owls entire body, including the legs and toes, and enables the bird to maintain a body temperature of 38 to 40°C, even when the air temperature reaches -50°C. In the breeding season, Snowy Owls are typically found from the treeline to the northern limit of Canada, preferring high, rolling tundra with tall points of land for nest sites and perches. In the High Arctic, nests are typically situated among such upland plants as willow, saxifrage, heather, and lichens, but in the Low Arctic, the owls tend to use dense, hummocky, dwarf shrub meadow for nesting.
