| Anas discors Linnaeus, 1766 |
The Blue-winged Teal (Anas discors) is a small dabbling duck.
The adult male has a greyish blue head with a white facial crescent, a light brown body with a white patch near the rear and a black tail. The adult female is mottled brown. Both sexes have a blue wing patch. In flight, they flap their wings especially rapidly.
Their breeding habitat is marshes and ponds throughout north and central North America. The nest is a shallow depression on the ground lined with grass and down, usually surrounded by vegetation.
They migrate in flocks to Central and South America. During migration, some birds may fly long distances over open ocean. They are occasional vagrants to Europe, where their yellow legs are a distinction from other small ducks like Common Teal and Garganey. DNA analysis of this species has revealed it's genetic make up to be almost identical to that of the Cinnamon teal.
These birds feed by dabbling in shallow water. They mainly eat plants; their diet may include molluscs and aquatic insects.
The call of the male is a short whistle; the female's call is a soft quack.
