Habitat

Breeds in small lakes, deep-water marshes, sheltered bays of large freshwater and alkali lakes , permanent and semi-permanent ponds, sloughs, potholes, and shallow river impoundments (Mowbray 2002) bordered by dense emergent vegetation or marshy areas (Campbell et al. 1990). In Yukon, nests in productive wetlands (Alexander et al. 2003) and a study in Manitoba indicated need for secure nesting site in a diversified wetland complex containing a variety of size, permanency, and cover types (Stoudt 1982).
