Snowy Owls, inhabitants of the Arctic, are not only well camouflaged but well insulated with their feathers. Their exceptional density make Snowy Owls North America’s heaviest owl. Weighing in at about four and a half pounds, they are about a pound heavier than Great Horned Owls and almost twice the weight of Great Gray Owls (North America’s tallest owl).
Most species of owls have densely-feathered legs (exceptions being owls living in southern regions such as Barn Owls, Burrowing Owls, and some tropical species). Snowy Owls have exceptionally thick feathering on their legs and feet. The toe feathers of a Snowy Owl are the longest known of any owl, averaging 1.3 inches – in comparison, the Great Horned Owl’s (which has the second longest toe feathers) are a mere .5 inch. In addition to their insulative quality, the feet and leg feathers may also serve to sense contact with prey and to protect against prey that might bite when seized.
