Muscovy duck

The Muscovy duck (Cairina moschata) is a large duck native to Mexico, Central, and South America. Small wild and feral breeding populations have established themselves in the United States, particularly in Florida, Louisiana, and the lower Rio Grande Valley of Texas as well as in many other parts of North America, including southern Canada. Feral Muscovy ducks are found in New Zealand, Australia, and in parts of Europe.
They are large ducks, with the males about 76 cm (30 in) long, and weighing up to 7 kg (15 lb). Females are considerably smaller, and only grow to 3 kg (6.6 lb), roughly half the males' size. The bird is predominantly black and white, with the back feathers being iridescent and glossy in males, while the females are more drab. The amount of white on the neck and head is variable, as well as the bill, which can be yellow, pink, black, or any mixture of these. They may have white patches or bars on the wings, which become more noticeable during flight. Both sexes have pink or red wattles around the bill, those of the male being larger and more brightly colored.

Although the Muscovy duck is a tropical bird, it adapts well to cooler climates, thriving in weather as cold as −12 °C (10 °F) and able to survive even colder conditions.[3][4] In general, Barbary duck is the term used for C. moschata in a culinary context.

The domestic breed, 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 is also more variable. Other names for the domestic breed in Spanish are pato casero ("backyard duck") and pato mudo ("mute duck").
