description Gadwall Overview
The gadwall, Mareca strepera, is a medium-sized dabbling duck distributed across much of the Northern Hemisphere. Adult males have finely patterned gray plumage, a black rear end, and a white wing patch, while females are mottled brown and can resemble female mallards. Gadwalls feed mainly in shallow wetlands by tipping forward for aquatic vegetation, although they also take invertebrates and sometimes seize food brought to the surface by coots or diving birds.
