Habitat

Breeds on freshwater lakes on arctic and subarctic tundra and taiga with varying topography and in both treeless and forested areas (Bergman and Derksen 1977). At the Y-K Delta nested in wet marsh tundra and heath tundra with lacustrine ponds of 1.5 ha and 1.5 m depth. All ponds used contained ninespine stickleback with no other fish. Vegetation was dominated by bur-reed, marsh five-finger, sedges, and mare’s tail; submergent vegetation primarily pondweeds (Petersen 1989). Other wetland types used include basin complex lakes, beaded streams, shallow ponds, deep lakes with abrupt shores, sublittoral shelves, and coastal wetlands (Russell 2002).
