Range Extent Comments
BREEDS: southeastern and east-central Alaska, central British Columbia eastward through northern Saskatchewan to Newfoundland, south to northeastern California, southeastern Arizona, southern Colorado, Iowa, Illinois, Pennsylvania (formerly), northern New York, Massachusetts. WINTERS: southeastern Alaska, southwestern U.S., southern Illinois, and Massachusetts south through Mexico to Panama, Grenada, West Indies; rarely Hawaii. (AOU 1983). In the U.S., the highest winter densities occur in eastern New Mexico (Bitter Lake refuge), the Mississippi River in Mississippi, Lake Isom and Reelfoot refuges (Missouri-Tennessee), the Florida panhandle (St. Marks refuge), eastern Texas panhandle, and southern San Joaquin Valley in California (Root 1988).
Ecology & Habitat

Habitat

Marshes, lakes, rivers, swamps, especially in wooded areas. Winters primarily on freshwater and brackish situations of larger lakes, rivers, and estuaries (AOU 1983); prefers deep open water (Stiles and Skutch 1989). Sleeps by day near emergent vegetation by lakeshores (Madge and Burn 1988). Birds close to the coast may spend their nights out at sea but come in at dawn to feed in fresh water (Root 1988). In Minnesota, ducklings spent most of time in open water, used islands of decayed vegetation for resting (Wilson Bull. 104:472-484). Nests at margins of small ponds, sloughs, bogs, and marshes.

Ecology

Usually widely dispersed in winter, but concentrations of several thousand not uncommon (Terres 1980). Usually in flocks (Stiles and Skutch 1989). In Maine, daily survival rate of duckling was reduced in low-pH wetlands (Mcauley and Longcore, 1988, J. Wildl. Manage. 52:169-176).

Reproduction

Clutch size is 6-14 (usually 8-10). Incubation, by female, lasts 25-29 days (Terres 1980). Young are tended by female, can fly about 49 days after hatching.
