Although mainly feeding near the surface of ponds and lakes, it also dives regularly to find aquatic invertebrates and vegetation. During the winter it is usually in pairs or small flocks and often associates with American Wigeon. The nest is hidden in dense grass of marshes and made of surrounding vegetation. This species occurs commonly throughout the Northern Hemisphere in Europe and Asia as well as in Africa.

The four-digit banding code is GADW.
