Domestic Muscovy Ducks

The domestic subspecies, Cairina moschata domestica, is commonly known in Spanish as the pato criollo ("creole duck"). They have been bred since pre-Columbian times by Native Americans and are heavier and less able to fly long distances than the wild subspecies. Their plumage color are also more variable. Muscovy ducks are brownish-black in coloration, with iridescent green and purple dorsal plumage and white wing patches. The legs and feet are grayish-black and the iris is yellowish-brown. Males and females are similar in appearance, but males are nearly twice as large as females. In addition, males have a patch of bare black skin surrounded by pinkish-red caruncles (fleshy outgrowths) which extends from the back of the eye to the bill. Although relatively silent, the male produces a low hissing sound and the female has a short, weak "quack."
