Conservation status | Still an abundant species, with population in the millions, but has declined seriously in some areas. Dense concentrations are vulnerable to oil spills and other pollution in northern seas. Large numbers are sometimes caught and killed in fishing nets. |
---|---|
Family | Ducks and Geese |
Habitat | Ocean, large lakes; in summer, tundra pools and lakes. For breeding season favors both low-lying tundra and hilly areas, barren ground and edges of northern forest, as long as open water is nearby. At other seasons mostly on ocean, including far from shore among pack ice; also on Great Lakes and sometimes elsewhere on fresh water. |
forages by diving and swimming underwater, with wings partly opened but propelled mainly by feet. Most feeding is within 30' of surface; supposedly able to dive more than 200', deeper than any other duck.
6-8, sometimes 5-11. Olive-buff to olive-gray. Incubation is by female, 24-29 days. Female covers eggs with down when leaving nest. Young: leave nest shortly after hatching, can swim and dive well when quite small. Young are tended by female, but feed themselves; may feed on items dislodged to surface by diving of female. Age at first flight about 35-40 days.

mollusks, crustaceans, insects. Diet at sea mainly mollusks (including mussels, clams, periwinkles) and crustaceans (including amphipods and isopods); also a few small fish. In summer on breeding territory eats mostly aquatic insects, also crustaceans, mollusks, fish eggs, and some plant material including grasses and pondweeds.
First breeds at age of 2 years. Courtship display begins by early winter, but most pair formation occurs in early spring. Displays of male include shaking head back and forth, raising long tail high in air, tossing head back with bill pointed up while calling. Nest site is on dry ground close to water, often partly hidden under low growth or among rocks. Nest is a depression lined with available plant material and with large amount of down, the down being added after some eggs are laid.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

The Yup’ik art of sewing feather-lined parkas for babies was nearly lost after the government outlawed the spring waterfowl hunt. Luckily, a centenarian Elder remembered how it’s done.
