Food & Habitat

Prefers shallow ponds with lots of emergent vegetation. Along the coast, it prefers tidal creeks, mudflats and marshes to more open water.

Green-winged teal are dabbling ducks. Their diet is varied, including insects and aquatic vegetation, and changes with availability of food.

Breeding & Population

Green-winged teal form pairs on their wintering grounds, during spring migration or on breeding grounds. They pair late relative to other dabblers. Females select nest sites in dense vegetation, and lay an average clutch of 10-12 eggs at a rate of 1 egg/day. Females incubate eggs for 20-23 days after the last egg is laid. Males abandon females to undergo a feather molt shortly after incubation begins.

They breed throughout Canada, Alaska, northern United States, Great Plains and the Great Lakes area.

Migration

Green-winged teal winter along the Pacific coast from Alaska south, in most of the United States, Mexico, and the Caribbean.
