Blue-winged teals are small ducks from the Anatidae family. Their head is bluish-gray with a white crescent in front of their eyes. Their body is spotted brown from the chest to the tail.
When their wings are unfurled, there is a distinct blue patch on the shoulders bordered with green and white. Females have the same scaly, brown pattern on their bodies, but they have no distinctive white markings on their faces.
Length: 15 – 17 in (38 – 43 cm)
Weight: 19.18 oz (544 g)
Wingspan: 23 -31 in (58 – 79 cm)
Blue-winged Teals breed in the US and Canada before migrating to Florida, the Gulf Coast, the southern West Coast, Mexico, Central and northern South America, and the Caribbean.
Habitat And Diet
You can find Blue-winged Teals on shorelines with calm or sluggish water, so lakes and ponds with protruding trees and rocks are perfect. They also live around shallow water sources with abundant vegetation, like marshes and swamps.
During the breeding season, you’ll find them in northern prairies and parklands.
Blue-winged Teals mostly eat aquatic plants that they find on the surface of their water. They may also eat aquatic insects, particularly during the breeding season.
Blue-winged Teal Calls:
They make high-pitched chattering calls, and females also quack.

Nests of Blue-winged Teals are often found in a hollow in the ground, sheltered behind tall grasses, and near a water source. They are built from grass and weeds and lined with down.
Females lay up to fifteen eggs that they incubate for 2 to 3 weeks. The young ducklings may be able to walk a few hours after hatching, but they can only fly after six to seven weeks.
Because of their long, over-ocean migration patterns, Blue-winged Teals have the highest mortality rate among dabbling ducks.
