The Ancona is a breed of domestic duck, characterised by an unusual and variable broken-colored plumage pattern. It is not clear whether it originated in the United Kingdom or in the United States. It is not clear whether it originated in the United Kingdom or in the United States.
This is a list of the breeds of domestic duck which have official recognition at national or international level. [1]Most breeds of duck derive from the wild mallard, Anas platyrhynchos, while a small minority are descendants of the Muscovy duck, Cairina moschata.
Female mallard ducks (as well as several other species in the genus Anas, such as the American and Pacific black ducks, spot-billed duck, northern pintail and common teal) make the classic "quack" sound while males make a similar but raspier sound that is sometimes written as "breeeeze", [29] [self-published source?] but, despite widespread ...
The male is generally silent, though he may whistle softly as part of his courtship display. The female growls softly—a sound transcribed as krrr—if she is flushed. [16] The duckling has a short contact call of two to four notes. If distressed, its calls are higher and faster than are those of Anas ducklings of the same size and age. [14]
The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks.
The male then swims ahead of her and turns the back of his head towards the female. [7] Once courtship is finished, the two birds are paired for the year. The male initiates copulation by alternating bill dipping and preening dorsally towards the female, upon which the female may return to the male.

The male does not have an eclipse plumage. Juveniles are browner and duller than adults. The legs and feet are bright orange. [14] The eastern spot-billed duck is darker and browner than the Indian spot-billed duck; its body plumage is more similar to the Pacific black duck. It lacks the red bill spot, and has a blue speculum. [14] [15]
