This is a small, fast-flying puddle duck that flies in flocks and is a common breeder throughout the prairies of Canada and many Midwestern states, including Minnesota. Sensitive to cold weather, blue-winged teal migrate south in late September and early October, much sooner than most ducks in Minnesota.
General description: A very small duck.
Length: About 15 inches long.
Weight: About 1 pound.
Color: The male has a white facial crescent, chestnut spots on the breast and pale blue wing patches. The female is uniformly gray-brown with pale blue wing patches. Both sexes have small black bills.

Blue-winged teal lay eggs in early June. The nest consists of 10 to 12 eggs laid in grassy fields or road ditches. The eggs hatch in 24 days.
Aquatic insects, weed seeds, plants.
Mink, fox, raccoons, skunks, hawks and owls.
Small- to medium-sized wetlands, small lakes and the back bays of rivers. In the spring, blue-winged teal breed in prairie areas of the United States and Canada, but will fly further north if wetlands are dry. In the fall, they'll migrate south to Columbia, Venezuela, Mexico and the Texas and Louisiana Gulf Coast.
Population and management
Blue-winged teal have thrived in recent years with wet conditions on the prairies of the Midwest and Canada.
Blue-winged teal and cinnamon teal look nearly identical in the fall. However, as spring approaches, the two species acquire distinctly different breeding plumage (feathers).
