The snowy owl, also known as the polar owl, the white owl and the Arctic owl, is a large, white owl of the true owl family. Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. Both sexes, but particularly the males, make low, powerful, slightly rasping hoots. They’re often given two at a time but may include up to six hoots in a row. These can be heard for up to 7 miles on the tundra, and other owls often answer with hoots of their own. When agitated, Snowy Owls snap their bills shut to make a clacking sound. In defense, Snowy Owls will hoot, whistle, and hiss. Here is a link to all their songs, cries and other noises.
