Our Animals > Muscovy Duck
The Muscovy Duck (Cairina moschata) is a large duck which is native to Mexico and Central and South America. A small wild population reaches into the United States in the lower Rio Grande Valley of Texas. There also are feral breeding populations in North America in and around public parks in nearly every state of the USA and in the Canadian provinces; feral populations also exist in Europe. Although the Muscovy Duck is a tropical bird, it adapts to icy and snowy conditions down to –12°C (10°F) and below without ill effects.
All Muscovy Ducks have long claws on their feet and a wide flat tail. The drake (male) is about 86 cm long and weighs 4.6-6.8 kg (10-15 lb), while the hen (female) is much smaller, at 64 cm in length and 2.7-3.6 kg (6-8 lb) in weight; domesticated males often weigh up to 8 kg (17 lb), and domesticated females up to 5 kg (10 lb). One male of an Australian breed weighed about 10 kg (20 pounds).
The wild Muscovy Duck is blackish, with large white wing patches. Domesticated birds may look similar; most are dark brown or black mixed with white, particularly on the head. Other colors such as lavender or all-white are also seen. Both sexes have a nude black-and-red or all-red face; the drake also has pronounced caruncles at the base of the bill and a low erectile crest of feathers.
C. moschata ducklings are mostly yellow with buff-brown markings on the tail and wings. Some domesticated ducklings have a dark head and blue eyes, others a light brown crown and dark markings on their nape. They are agile and speedy precocial birds.
