Natural History and Habitat Use

American Wigeon -- Anas americana


RANGE: Breeds from central Alaska and central Yukon to New Brunswick and southern Nova Scotia, south to northeastern California, central Colorado, South Dakota, southern Ontario, and northern New York, sporadically to the Atlantic Coast. Winters from southern Alaska to southern Nevada, sporadically across the central United States to the southern Great Lakes and Ohio Valley, and on the Atlantic Coast from Nova Scotia south throughout the southern United States to Central America.

STATUS: Common.

HABITAT: Inhabits freshwater wetlands and lakes from tundra to shortgrass and mixed prairie, preferring permanent to temporary waters. Commonly associates with diving ducks, and in winter frequents coastal marshes and bays, wet meadows, and shallow freshwater and brackish ponds.

SPECIAL HABITAT REQUIREMENTS: Large lakes, ponds, marshes, sluggish streams and rivers, with open water and exposed shoreline.

NEST: Nests in a hollow on dry ground on an island or on shore, in tall grasses or weeds, or at the base of a tree or bush, as far as 400 yards from water.

FOOD: Feeds by grazing and gleaning in wet or dry pastures and fields, by dabbling on the water surface in shallow water along marsh edges and sloughs, and by scavenging for wild celery after diving ducks have torn plants loose from bottom. Primarily vegetarian, eats mainly leaves, stems, and buds of aquatic plants; also feeds on waste grains, mollusks, crustaceans, and insects.
