Poultry are domesticated birds kept by humans for their eggs, their meat or their feathers. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes birds that are killed for their meat, such as the young of pigeons but does not include similar wild birds hunted for sport or food and known as game. The word "poultry" comes from the French/Norman word poule, itself derived from the Latin word pullus, which means small animal.
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.
Foie gras is a specialty food product made of the liver of a duck or goose. According to French law, foie gras is defined as the liver of a duck or goose fattened by gavage. In Spain and other countries, it is occasionally produced using natural feeding. Ducks are force-fed twice a day for 12.5 days and geese three times a day for around 17 days. Ducks are typically slaughtered at 100 days and geese at 112 days.
The mallard or wild duck is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa, and 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 purple patches on their wings, while the females have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent 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. This species is the main ancestor of most breeds of domestic ducks.
The Muscovy duck is a large duck native to the Americas. Small wild and feral breeding populations have 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. Feral Muscovy ducks are found in New Zealand, Australia, and in parts of Europe.
The Pacific black duck, commonly known as the PBD, is a dabbling duck found in much of Indonesia, New Guinea, Australia, New Zealand, and many islands in the southwestern Pacific, reaching to the Caroline Islands in the north and French Polynesia in the east. It is usually called the grey duck in New Zealand, where it is also known by its Maori name, pārera.
In cooking and gastronomy, duck or duckling is the meat of several species of bird in the family Anatidae, found in both fresh and salt water. Duck is eaten in many cuisines around the world. It is a high-fat, high-protein meat rich in iron. Duckling nominally comes from a juvenile animal, but may be simply a menu name.
The domestic duck or domestic mallard is a variety 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.
The Pekin or White Pekin is an American breed of domestic duck, raised primarily for meat. It derives from birds brought to the United States from China in the nineteenth century, and is now bred in many parts of the world. It is often known as the American Pekin to distinguish it from the German Pekin, a distinct and separate breed which derives from the same Chinese stock but has different breeding. Many of these ducks were reared on Long Island, New York, in the late nineteenth and early twentieth centuries, from which the breed derived its name Long Island Duck.
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 found 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.
A bird hybrid is a bird that has two different species as parents. The resulting bird can present with any combination of characters from the parent species, from totally identical to completely different. Usually, the bird hybrid shows intermediate characteristics between the two species. A "successful" hybrid is one demonstrated to produce fertile offspring. According to the most recent estimates, about 16% of all wild bird species have been known to hybridize with one another; this number increases to 22% when captive hybrids are taken into account. Several bird species hybridize with multiple other species. For example, the mallard is known to interbreed with at least 40 different species. The ecological and evolutionary consequences of multispecies hybridization remain to be determined.
The Campbell is a British breed of domestic duck. It was developed at Uley, in Gloucestershire, England, at the turn of the 20th century; being introduced to the public in 1898 and the Khaki variety in 1901.
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.
Gamebird hybrids are the result of crossing species of game birds, including ducks, with each other and with domestic poultry. These hybrid species may sometimes occur naturally in the wild or more commonly through the deliberate or inadvertent intervention of humans.
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, UK, 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 Bali Duck is a lightweight breed of domesticated duck raised primarily for decoration or as pets, although they are good layers. It is similar to the Indian Runner Duck, differing only in having a crest on the top of the head.
The production of foie gras involves the controversial force-feeding of birds with more food than they would eat in the wild, and more than they would voluntarily eat domestically. The feed, usually corn boiled with fat, deposits large amounts of fat in the liver, thereby producing the fatty consistency sought by some gastronomes.
The Muscovy or Barbary is the domesticated form of the wild Muscovy duck. There are a number of local or regional breeds, and drakes of these are commonly cross-bred with domestic ducks to produce the hybrids called mulards.
The German Pekin, German: Deutsche Pekingente, is a European breed of domestic duck. It is commonly called simply Pekin or White Pekin. It is a different breed from the American Pekin, which is also commonly known by the same names. It was bred in Europe from birds originating in China and Japan and is distributed in many European countries.
