Surface diving; dabbling; coastal. Winters: Norway to Spain, Black, Caspian and Mediterranean Seas; coastal East Asia, south to Japan and China; Atlantic and Pacific coastlines to Baja California, south Carolina, Florida, and Gulf coast (Ref. 356). They breed on wooded coastlines, small freshwater lakes, pools and rivers. They inhabit areas with boulder-covered or small rocky islands available for nesting with extensive herbaceous vegetation, shrubs and low trees. For the non-breeding population, winters are in shallow areas of inshore coastal waters; especially in water inlets where there are large mussel-beds but they also occur in freshwater habitats such as lakes and estuaries during migration (Ref. 83520). Feeds on clams, snails, barnacles, mussels and crabs found along the coast (Ref. 94965).
