(Anas crecca) M, Y
|
 |
RANGE: Breeds from Alaska, northwestern and southern Mackenzie
to north-central Labrador and Newfoundland south to central
, Colorado, southern Ontario and Quebec, and Nova Scotia;
breeds locally from southern California east to southern New
Mexico, Iowa, and Pennsylvania, and on the Atlantic Coast to
Delaware. Winters from southern Alaska and southern British
Columbia to New Brunswick and Nova Scotia south to Central
America; also winters in the Hawaiian Islands.
STATUS: Relatively common throughout range.
HABITAT: Inhabits inland waters with dense rushes or other
emergent vegetation on mixed and shortgrass prairies, and
northern boreal forests. May be found resting on mudbanks or
stumps, or perching on low limbs of dead trees. Winters in both
freshwater and brackish marshes, ponds, streams, and estuaries.
SPECIAL HABITAT REQUIREMENTS: Lakes, marshes, ponds, pools, and
shallow streams. Strongest nesting habitat association
along the edges of freshwater marsh.
NEST: Nests in a depression on dry ground located at the base of
shrubs, under a log, or in dense grass, usually 2 to 300 feet
(but up to one-quarter mile) from water.
FOOD: Feeds in shallow marshes or temporarily flooded fields by
dabbling, or by probing on mud flats. Consumes a diet that is
about 90 percent vegetative, consisting of seeds of aquatic
plants, grains, berries, wild grapes, mast, and (to a lesser
extent) the vegetative parts of aquatic plants. Also eats some
insects, small mollusks, and crustaceans.
