Domesticated duck
Extracted from the Wikipedia article Domestic duck.
Domestic ducks (mainly mallards, Anas platyrhynchos domesticus, with some Muscovy ducks, Cairina moschata domestica) are ducks that have been domesticated and raised for meat and eggs. A few are kept for show, or for their ornamental value. Domesticated ducks are descended mainly from the mallard, which was domesticated in China around 2000 BC, with contributions from the Muscovy duck.
