|Conservation status||Population is stable, and large enough to sustain a limited hunting season in some areas.|
|Family||Ducks and Geese|
|Habitat||Tundra (summer), lakes, large rivers, bays, estuaries, flooded fields. In summer on northern tundra with many lakes and ponds, generally near the coast. During migration and winter mainly on shallow lakes, wide slow-moving rivers, and coastal estuaries, especially those with agricultural fields nearby.|
in nesting season forages mainly in water by dabbling at surface, dipping head underwater, or upending with tail up and head straight down (can reach 3 feet below surface). On migration and in winter does much feeding on land in open fields. Sometimes feeds during moonlit nights.
4-5, up to 7. Creamy white, becoming stained. Female does about 3/4 of incubating, male does rest; eggs hatch in 31-32 days. Young: Both parents tend young, leading them to feeding sites in water. Adults may paddle with feet to bring submerged food to surface for young; may rarely feed young directly. Young fledge in 2-3 months, remain with parents at least through first winter.

seeds and other plant material. Summer diet mainly stems, seeds, and roots of aquatic plants, including sedges, pondweeds, arrowleaf, algae, and others; also a few small invertebrates. At other seasons, eats much grain in harvested fields of corn, barley, and soybean.
In one display involving members of a pair, the birds face each other, wings partly spread and rapidly quivering, while they call loudly. Nest site is near lake or other open water, on ridge or island with good visibility. Nest (built by both sexes) is low mound of plant material, 1 or 2 feet in diameter, with a depression in the center; may be used for more than 1 year.

Birds may leave nesting areas in late summer and concentrate in nearby estuaries. Southward migration begins mid-autumn. Migrating flocks (of up to 100 or more) are made up of family groups. May fly long distances between traditional staging areas in fall; spring migration may involve shorter flights and more stopovers.
