Maximum common depth based on occurrence (Ref. 115862). To be replaced with a better reference. Primarily lives in coastal marine waters approximately 9 months in a year. During breeding season, it frequents shallow wetlands towards the edge of the boreal forest; while non-breeding birds use deeper ponds, lakes and nearshore marine areas. Winter along the Pacific coast from the Bering Sea to as far as California; and some from Alaska may reach the northern Bering Sea across to Russia Foraging behavior involves diving and swimming underwater up to a depth of less than 9 meters. This duck has been recorded to dive up to 60 meters (Ref. 83519). Common diving depth is 2-3 m (9-10 ft) (Ref. 115862).
