A docile, domesticated version of the black duck, a favoured variety of wild duck, used for egg and meat production. It is said that a miller near Lake Cayuga in New York State captured two wild black ducks and pinioned them. The offspring produced well-flavoured meat. dult Cayuga ducks weigh around 3 kg (6 lb), and are characterised by a black bill and black plumage which is iridescent green in certain lights and with black shanks and toes. Ducklings have black plumage.
