It inhabits the tundra and mountainous areas around the North Pole, where it is one of the predators alongside the Roughleg, the Merlin and the Snowy Owl. The Gyrfalcon is predominantly a resident bird. In winter however, especially young falcons may occur to the south of their normal wintering range.
