Diet relies primarily on seeds. Diet is usually plant materials, particularly seeds of assorted grasses, sedges, pondweeds, smartweeds, and others. Snails, bivalves, bugs, crustaceans, and different animal matter could also be necessary within the diet at some seasons.

Pair formation begins in early winter and continues throughout spring migration. Male has different courtship shows, together with one wherein whole forepart of the body is submerged, tail raised, feet waved in the air.

The range is all of North America besides western and northern Alaska, northern Yukon Territory, northern Northwest Territories, and the northeastern area of Canada.

Blue-winged teal is rare within the desert southwest, and the west coast. The breeding habitat of the blue-winged teal is marshes and ponds.

The breeding range extends from east-central Alaska and southern Mackenzie District east to southern Quebec and southwestern Newfoundland.

In the contiguous United States, it breeds from northeast California east to central Louisiana, central Tennessee, and the Atlantic Coast.

The western blue-winged teal inhabits that a part of the breeding range west of the Appalachian Mountains. The Atlantic blue-winged teal nests alongside the Atlantic Coast from New Brunswick to Pea Island, North Carolina.

They migrate in flocks to winter into the south of its breeding range. During migration, some birds might fly long distances over an open ocean.

They are occasional vagrants to Europe, the place their yellow legs are a distinction from different small geese just like the common teal and garganey, and lately have been annual vagrants in Britain and Ireland.

The blue-winged teal winters from southern California to western and southern Texas, the Gulf Coast to the Atlantic Coast, the Caribbean, and south to Central and South America. It is commonly seen wintering as far south as Brazil and central Chile.

Blue-winged teal Habitat

Blue-winged teal inhabits shoreline more usually than open water and likes calm water or sluggish currents to quick water. They inhabit inland marshes, lakes, ponds, pools, and shallow streams with dense emergent vegetation.

Blue-winged teal winter on shallow inland freshwater marshes and brackish and saltwater marshes. They construct their nests on dry ground in grassy sites reminiscent of bluegrass meadows, hayfields, and sedge meadows.

They may also nest in areas with very short, sparse vegetation. Blue-winged teal typically nests inside a number of hundred yards of open water; nonetheless, nests have been discovered so far as 1.61 km (1 mi) away from water. Where the habitat is sweet, they nest communally.

Blue-winged teal usually uses heavy growth of bulrushes and cattails as escape cover. Grasses, sedges, and hayfields present nesting cover for these geese.

Erik Fritzell reported that blue-winged teal nests positioned in light to sparse cover had been more profitable than these in heavy cover. Nesting success was 47% on grazed areas and 14% on ungrazed areas.

The blue-winged teal is primarily discovered within the northern prairies and parklands. It is essentially the most considerable duck within the mixed-grass prairies of the Dakotas and the prairie provinces of Canada.

The blue-winged teal can be present in wetlands of boreal forest associations, shortgrass prairies, tallgrass prairies, and deciduous woodlands.

This duck generally inhabits wetland communities dominated by bulrush (Scirpus spp.), cattail (Typha spp.), pondweed (Potamogeton spp.), sedges (Carex spp.), widgeongrass (Ruppia maritima), and different emergent and aquatic vegetation.

During molting, it usually stays amongst in-depth beds of bulrushes and cattails. The blue-winged teal favors areas dominated by bluegrass (Poa spp.) for nesting. Hayfields and plant communities of buckbrush (Ceonothus cuneatus) and sedges are additionally necessary as nest sites.
