Breeds on inaccessible cliff ledges and small islands in Arctic and subarctic tundra. Winters predominantly on coastal grasslands, estuaries, salt marshes, and increasingly on inland agricultural fields at low elevations.
Almost exclusively herbivorous, primarily grazing on short, nutrient-rich grasses, sedges, mosses, and various small arctic and coastal plants. In winter, they frequently utilize agricultural crops such as winter wheat and barley.
