Poultry are domesticated birds kept by humans for the purpose of harvesting useful animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes waterfowls of the family Anatidae and other flying birds that are kept and killed for their meat such as the young pigeons, but does not include wild birds hunted for food known as game or quarry.
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water.
The mallard or wild duck is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm long. It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.
The wood duck or Carolina duck is a species of perching duck found in North America. The drake wood duck is one of the most colorful North American waterfowls.
The Muscovy duck is a duck native to the Americas, from the Rio Grande Valley of Texas and Mexico south to Argentina and Uruguay. Feral Muscovy ducks are found in New Zealand, Australia, and in Central and Eastern Europe. Small wild and feral breeding populations have also established themselves in the United States, particularly in Florida, Louisiana, Massachusetts, the Big Island of Hawaii, as well as in many other parts of North America, including southern Canada.
Hartlaub's duck is a dark chestnut-coloured duck of African forests. Formerly included in the paraphyletic "perching duck" assemblage, it was later moved to the dabbling duck assemblage. However, it is fairly distinct from the "typical" dabbling ducks, and is placed in the monotypic genus Pteronetta to reflect this.
The domestic duck or domestic mallard is a subspecies of mallard that has been domesticated by humans and raised for meat, eggs, and down feathers. A few are also kept for show, as pets, or for their ornamental value. Almost all varieties of domesticated ducks, apart from the domestic Muscovy duck, are descended from the mallard.
Indian Runners are a breed of Anas platyrhynchos domesticus, the domestic duck. They stand erect like penguins and, rather than waddling, they run. The females usually lay about 300 to 350 eggs a year or more, depending whether they are from exhibition or utility strains. They were bred on the Indonesian islands of Lombok, Java and Bali where they were 'walked' to market and sold as egg-layers or for meat. These ducks do not fly and only rarely form nests and incubate their own eggs. They run or walk, often dropping their eggs wherever they happen to be. Duck-breeders need to house their birds overnight or be vigilant in picking up the eggs to prevent them from being taken by other animals.
The Cayuga is an American breed of domestic duck. It was introduced to the Finger Lakes region of New York State in about 1840, and is named for the Cayuga people of that area. Until the last years of the nineteenth century it was the principal duck reared for meat in the United States. In the twenty-first century it is kept mainly for ornament.
The Swedish Blue or Blue Swedish is a Swedish breed of domestic duck. It originated in the former dominion of Swedish Pomerania – now in north-west Poland and north-east Germany – and is documented there from 1835. It is closely similar to the Pomeranian Duck from the same general area, differing mainly in its white primary feathers.
The Rouen is a heavyweight breed of domesticated duck. Rouens are raised primarily for meat, exhibition, or as general purpose ducks. Since they are not prolific egg layers, Rouen ducks are most commonly bred for their meat. The breed originated in France sometime before the 19th century.
The Orpington or Buff Orpington Duck is a breed of domestic duck. It is a dual-purpose breed used for meat and egg production. It is capable of laying up to 220 eggs a year. Originally created by William Cook of Orpington, Kent, England, from the selection of mis-marked Blue Orpington Ducks; Cook was also the developer of the Orpington chicken. The breeds used in the development of the breed included Cayuga, Indian Runner, commercial Aylesbury and Rouen. It is proposed that Cook's intentions for the breed were to capitalize on the growing demand for the buff colour pattern. The Buff Orpington Duck was introduced to the public at the Dairy Show, the Agricultural Hall (q.v.), Islington, London in October 1897. It is considered a threatened breed by the ALBC. This breed was admitted to the British Poultry Standard in 1910 and the American Poultry Associations Standard of Perfection as the 'Buff Duck' in the Medium class in 1914. The Orpington duck is available in three colour varieties: Buff, Blond and Brown. The Buff Orpington is an unstable colour due to a blue dilution gene which means that from the offspring, all three colour variations will appear.
The Magpie is a British breed of domestic duck. It has distinctive black and white markings reminiscent of the European magpie, and is a good layer of large eggs.
The Silver Appleyard is a British breed of domestic duck. It was bred in the first half of the twentieth century by Reginald Appleyard, with the aim of creating a dual-purpose breed that would provide both a good quantity of meat and plenty of eggs.
The Hook Bill or Dutch Hookbill is a breed of domestic duck characterised by an unusual down-curved beak. It is an ancient breed, and has been documented since the seventeenth century. Speculation that it originated in Asia, or is related to the Indian Runner, is apparently unsubstantiated.
The Abacot Ranger is a breed of domestic duck, initially known as the Hooded Ranger and as Streicherente. A utility breed, originally developed for eggs and meat, it is popular for exhibition and egg production today.
The Elizabeth is a breed of domestic duck, originating in Australia. They were developed as a small, fast growing meat breed in 1972 by Lance Ruting in Merrylands, New South Wales and named after his wife, Ann Elizabeth Ruting. They are presently bred in Australia and New Zealand, but are not widely available and classified as endangered by the Rare Breeds Trust of Australia.
The Duclair duck is a type of Rouen duck named after the town of Duclair in Normandy and traditionally raised in the region for both eggs and meat. Official standards were established for the breed on November 23, 1923.
The Blekinge duck, also known as the Coast Duck, is a medium-sized Swedish breed of domestic duck prominent to the county of Blekinge.
