The mallard (/ ˈ m æ l ɑːr d, ˈ m æ l ər d /) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa.
The female is light brown, with plumage much like a female mallard. It can be distinguished from that species by the dark orange-edged bill, smaller size, the white speculum, and white belly.

Those breeds are raised for meat and eggs, [ 2 ] while other breeds are purely ornamental, having been selected for their crests, tufts, or striking ...
