This dabbling duck is strongly migratory and winters further south than its breeding range. It is not as gregarious as some dabbling ducks outside of the breeding season and tends to form only small flocks. † See also Diving duck The dabbling ducks are a group of ten genera and about 55 species of ducks, including some of the most familiar Northern Hemisphere species. ...

The Gadwall is 46-56 cm long with a 78-90 cm wingspan. The breeding male is a beautifully patterned grey, with a black rear end and a brilliant white speculum, obvious in flight or at rest. In non-breeding (eclipse) plumage, the drake looks more like the female.
The females are light brown, with plumage much like a female Mallard. They can be distinguished from that species by the dark orange-edged bill, smaller size, and lack of an obvious speculum. Binomial name Anas platyrhynchos Linnaeus, 1758 The Mallard (Anas platyrhynchos) is a common and widespread dabbling duck which breeds throughout the temperate and sub-tropical areas of North America, Europe and Asia. ...

The Gadwall is a bird of open wetlands, such as prairie lakes, wet grassland or marshes with dense fringing vegetation, and usually feeds by dabbling for plant food with head submerged. It nests on the ground, often some distance from water. The young birds are fed insects at first; adults also eat some mollusks and insects during the nesting season. Prairie refers to an area of land in North America of low topographic relief that principally supports grasses and herbs, with few trees, and is generally of a mesic (moderate or temperate) climate. ...
This is a fairly quiet species. The male has a hoarse whistling call, whereas the female has a mallard-like quack.
