During breeding season, which begins in May, snowy owls can be found on open tundra all the way around the Arctic Circle. In North America, some of the owls may stay on the breeding grounds through the rest of the year, weathering temperatures as low as -80°F. Others migrate as far south as the northern half of the lower 48 states. In the northeast, snowy owls are regular visitors to New York and New England.
