Anas platyrhynchos domesticus

Also known as Pekin Duck, Barnyard Duck, Farm Duck

Domestic ducks descend primarily from wild mallards, bred over millennia for eggs, meat, and colorful plumage. Many breeds are too heavy for flight, relying on dense waterproof feathers and webbed feet to navigate farmyards and suburban ponds. They forage by dabbling upside down in shallow water, sifting through silt for seeds, invertebrates, and greens.
