Mallard (Anas platyrhynchos) is the most widely known wild duck. Its length is 15 ot 16 inches and wingspan is 36 inches. It is a medium-to-large dabbling duck that is identified by the male's glossy green head and white collar around the neck. The female is of an overall brown color. Both sexes have orange feet and a purple-blue speculum with both sides outlined in white. They swim with their tail held above the water. The sudden flight of Mallards can make quite a spectacular sight.
Mallards are seasonally monogamous. The male deserts the female after the first week of incubation.
