Context: The Muscovy duck has been domesticated for centuries, and is widely traded as "Barbary duck". Muscovy breeds are popular because they have stronger-tasting meat — sometimes compared to roasted beef — than that of the domestic duck. The meat is lean when compared to the fatty meat of mallard-derived ducks, its leanness and tenderness being often compared to veal. Muscovy ducks are also less noisy, and sometimes marketed as a "quackless" duck; even though they are not completely silent, they do not actually quack (except in cases of extreme stress). The carcass of a Muscovy duck is also much heavier than most other domestic ducks, which makes it ideal for the dinner table.
