Domestic means that these animals were bred in captivity for human use; whether that be livestock or companionship. Domestic ducks are typically larger than your average wild duck species. Most domestic ducks, besides the Muscovy Duck, are descended from the Mallard Duck. The duck with red markings on its face is specifically a Muscovy Duck. Wild Muscovy Ducks are native to Mexico and Argentina, but most were domesticated to be used as livestock. Today, domestic Muscovy Ducks are a common occurrence in ponds and lakes here in the United States.
