Conservation status: least_concern
The Gadwall is a widespread dabbling duck belonging to the Anatidae family, thriving in diverse freshwater wetland environments. It is generally found foraging across shallow waters and along riverbanks, classifying it as a highly adaptable waterfowl species.
How To Identify
This medium-sized duck typically features mottled plumage composed of browns, tans, and greys, offering excellent camouflage near reeds. Males possess slightly richer markings than females but both share the characteristic stout build and somewhat streaked appearance.
Habitat
Gadwalls inhabit shallow freshwater lakes, marshes, ponds, and wetlands with emergent vegetation across temperate and boreal regions of the Northern Hemisphere, and locally in southern Africa and Australia.
Behaviour
Gadwalls often steal food disturbed by other dabbling ducks, a foraging strategy called kleptoparasitism, allowing them to exploit the feeding efforts of more aggressive species.
Native Range
The Gadwall is native to northern areas of Europe, across the Palearctic, and central North America.
Did You Know?
Gadwalls are dabbling ducks that often feed by tipping forward like other surface feeders, but they also frequently dive—an unusual behavior for their genus. Despite their modest gray and brown plumage, males perform elaborate courtship displays with synchronized movements.
