It differs from large gulls in that it seldom scavenges in garbage dumps, and it nests in trees, not on the ground.

Habitat: Ocean bays, lakes, muskeg. Breeds in edges of northern forest where coniferous trees are near lakes or bogs. In migration and winter, on many kinds of waters, including rivers and lakes inland, coastal estuaries and lagoons, sometimes well offshore on ocean. Often concentrates at sewage treatment ponds, probably to feed on the abundant insects.

Diet: Insects, crustaceans, fish.
