muscovy ducks - also called Cape ducks...

The Spanish explorers who took the muscovy ducks to Europe from Central and South America in the 16th century knew they would not go hungry on the way back. They also had something to bring home: an easy to keep, domesticated animal with a lot of meat.
The ducks they found from Peru to Mexico also turned out to taste very good, a culinary delicacy that still circulates around the world under the name Barbary duck.
The original name - muskavyduck - does not refer to Moscow, as is sometimes said, but to the Miskito Indians of Nicaragua and Honduras, or the Muisca, a Colombian Indian tribe. In any case, the ducks in that part of the world served as food for centuries and were especially popular because of their high fertility, which allowed them to reproduce quickly, sometimes with three nests a year.
