Found along seacoasts, estuaries, bays, and dumps, less commonly on large inland lakes and rivers (AOU 1983). In winter will roost with other wintering gulls on offshore rocky islets, agricultural fields, beaches and spits (Campbell et al. 1990). Usually nests on cliffs facing sounds on arctic islands.
