A domestic goose is a goose that humans have domesticated and kept for their meat, eggs, or down feathers, or as companion animals. Domestic geese have been derived through selective breeding from the wild greylag goose (Anser anser domesticus) and swan goose (Anser cygnoides domesticus).
In Europe, northern Africa, and western Asia, the original domesticated geese are derived from the greylag goose (Anser anser). In eastern Asia, the original domesticated geese are derived from the swan goose (Anser cygnoides); these are commonly known as Chinese geese. Both have been widely introduced in more recent times, and modern flocks in both areas (and elsewhere, such as Australia and North America) may consist of either species or hybrids between them. Chinese geese may be readily distinguished from European geese by the large knob at the base of the bill, though hybrids may exhibit every degree of variation between the two species. [1]
Charles Darwin remarked in The Variation of Animals and Plants Under Domestication that the domestication of geese is of a very ancient date. [2] There is archaeological evidence for domesticated geese in Egypt more than 4,000 years ago. [3] It has been proposed that geese were domesticated around 3000 BCE in southeastern Europe, possibly in Greece, but reliable evidence of domestic geese comes from a much later period (8th century BCE) in the Odyssey. Another potential domestication site is in Egypt during the Old Kingdom (2686–1991 BCE) due to iconographic evidence of goose exploitation, but this scenario for the original domestication event has been considered less likely. Geese were also herded by ancient Mesopotamians for food and sacrifices and depicted in Mesopotamian art from the early Dynastic Period (2900–2350 BCE) onwards. Certainly, fully domesticated geese were present during the New Kingdom times in Egypt (1552–1151 BCE) and contemporaneously in Europe, and goose husbandry involving several varieties was well established by the Romans by the 1st century BCE. In the Medieval Period, goose husbandry was at its peak with large flocks kept by peasants. Archaeological evidence of the domestic goose in northern Europe indicates that it was probably introduced into Scandinavia during the Early Iron Age (400 BCE–550 CE). [4]
Domestic geese have been selectively bred for size, with some breeds weighing up to 10 kilograms (22 lb), [3] compared to the maximum of 3.5 kilograms (7.7 lb) for the wild swan goose and 4.1 kilograms (9.0 lb) for the wild greylag goose. [5] This affects their body structure; whereas wild geese have a horizontal posture and slim rear end, domesticated geese lay down large fat deposits toward the tail end, giving a fat rear and forcing the bird into a more upright posture. Although their heavy weight affects their ability to fly, most breeds of domestic geese are capable of flight.
Geese have also been strongly selected for fecundity, with females laying up to 500 eggs per year, compared to 5–12 eggs for a wild goose. [3] [5]
As most domestic geese display little sexual dimorphism, sexing is based primarily on physical characteristics and behaviour. Males are typically taller and larger than females, and have longer, thicker necks. In addition, males can be distinguished by the protective behaviour they exhibit towards their mates and their offspring – the male will typically stand between his partner and any perceived threat.
Changes to the plumage are variable; many have been selected to lose dark brown tones of the wild bird. The result is an animal marked, or completely covered in white feathers. Others retain plumage close to the natural; some, such as the modern Toulouse goose look almost identical to the greylag in plumage, differing only in structure. White geese are often preferred as they look better plucked and dressed, with any small down feathers remaining being less conspicuous. From the time of the Romans, white geese have been held in great esteem.
Geese produce large edible eggs, weighing 120–170 grams (4.2–6.0 oz). [3] They can be used in cooking just like chicken's eggs, though they have proportionally more yolk, and this cooks to a slightly denser consistency. The taste is much the same as that of a chicken egg, but gamier.
Like their wild ancestors, domestic geese are very protective of their offspring and other members of the flock. The gander will normally place himself between any perceived threat and his family. Owing to their highly aggressive nature, loud call and sensitivity to unusual movements, geese can contribute towards the security of a property. [3] In late 1950s South Vietnam, the VNAF used flocks of geese to guard their parked aircraft at night due to the noise they would make at intruders. [6]
Because domestic geese descended from the greylag goose are effectively the same species as their wild ancestor (being a subspecies formed through domestication), escaped individuals readily breed with wild populations, resulting in the offspring sometimes resembling either one of their parents, or bearing mixed plumage with patterns of grey and white feathers and orange beaks.
Due to their tendency to make noise when approached by strangers, about 500 geese were used to supplement dogs, drones, and humans to patrol the 533-km boundary between Chongzuo and Vietnam during the COVID-19 pandemic. An official commented that the birds, one of the most common livestock in the region, are sensitive to sounds and can sometimes be more aggressive than dogs. [7]
Geese are important to multiple culinary traditions. The meat, liver and other organs, fat, skin, blood and eggs are used culinarily in various cuisines. [8]
When Aphrodite first came ashore she was welcomed by the Charites (Roman "Graces"), whose chariot was drawn by geese.
There are Mother Goose tales, such as a farmwife might have told; there is the proverbial goose that laid the golden eggs, warning about the perils of greed.
The geese in the temple of Juno on the Capitoline Hill were said by Livy to have saved Rome from the Gauls around 390 BC when they were disturbed in a night attack. [9] The story may be an attempt to explain the origin of the sacred flock of geese at Rome.
Poultry are domesticated birds kept by humans for the purpose of harvesting 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 but does not include wild birds hunted for food known as game or quarry.
A goose is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera Anser and Branta. Some members of the Tadorninae subfamily are commonly called geese, but are not considered "true geese" taxonomically. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.
The greylag goose or graylag goose is a species of large goose in the waterfowl family Anatidae and the type species of the genus Anser. It has mottled and barred grey and white plumage and an orange beak and pink legs. A large bird, it measures between 74 and 91 centimetres in length, with an average weight of 3.3 kilograms. Its distribution is widespread, with birds from the north of its range in Europe and Asia often migrating southwards to spend the winter in warmer places, although many populations are resident, even in the north. It is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BCE. The genus name and specific epithet are from anser, the Latin for "goose".
The greater white-fronted goose is a species of goose, closely related to the smaller lesser white-fronted goose. The greater white-fronted goose is migratory, breeding in northern Canada, Alaska, Greenland and Russia, and winters farther south in North America, Europe and Asia. It is named for the patch of white feathers bordering the base of its bill: albifrons comes from the Latin albus "white" and frons "forehead". In the United Kingdom and Ireland, it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose, and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America.
The lesser white-fronted goose is a goose closely related to the larger greater white-fronted goose. It breeds in the northernmost Palearctic, but it is a scarce breeder in Europe, with a reintroduction attempt in Fennoscandia.
The snow goose is a species of goose native to North America. Both white and dark morphs exist, the latter often known as blue goose. Its name derives from the typically white plumage. The species was previously placed in the genus Chen, but is now typically included in the "gray goose" genus Anser.
The emperor goose, also known as the beach goose or the painted goose, is a waterfowl species in the family Anatidae, which contains the ducks, geese, and swans. In summer, the emperor goose is found in remote coastal areas near the Bering Sea in arctic and sub-arctic Alaska and the Russian Far East, where it breeds in monogamous pairs. It migrates south to winter in ice-free mudflats and coasts in Alaska, mostly the Aleutian Islands, and Canada's British Columbia, rarely reaching the contiguous United States. Listed as near threatened by the International Union for Conservation of Nature, the species' population is declining due to threats such as pollution, hunting, and climate change.
The swan goose is a large goose with a natural breeding range in inland Mongolia, Northeast China, and the Russian Far East. It is migratory and winters mainly in central and eastern China. Vagrant birds are encountered in Japan and Korea, and more rarely in Kazakhstan, Laos, coastal Siberia, Taiwan, Thailand and Uzbekistan.
The Chinese is an international breed of domestic goose, known by this name in Europe and in North America. Unlike the majority of goose breeds, it belongs to the knob geese, which derive from Anser cygnoides and are characterised by a prominent basal knob on the upper side of the bill. It originates in China, where there are more than twenty different breeds of knob goose.
Domestic ducks are ducks that have been domesticated and raised for meat and eggs. A few are kept for show, or for their ornamental value. Most varieties of domesticated ducks, apart from the Muscovy duck and hybrids, are descended from the mallard, which was domesticated in China around 2000 BC.
Anser is a waterfowl genus that includes the grey geese and the white geese. It belongs to the true goose and swan subfamily of Anserinae under the family of Anatidae. The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed farther south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) and 5 °C (41 °F) isotherms.
The American Buff is an American breed of domestic goose. It was accepted by the American Poultry Association in 1947. It is named for its single plumage variety, which is a pale buff or apricot-fawn in color.
The Sebastopol is a breed of domestic goose, descended from the European Greylag goose. First exhibited in England in 1860 under the name 'Sebastopol goose'; they were also referred to as Danubian geese, a name first used for the breed in Ireland in 1863. 'Danubian' was used as a synonym in the 19th century; and only given precedence by Edward Brown after the turn of the 19th century. The Sebastopol is a medium-sized goose with long, white curly feathers. The feathers of the neck are smooth and sometimes greyish brown. Crosses have produced all-grey, buff, and saddle back variants. Feathers on the breast may be curly (frizzle) or smooth. The gander weighs 12-14 lbs while the goose weighs 10-12 lbs. The legs and shanks are orange and the eyes bright blue. Grey and buff colored Sebastopol have brown eyes. On average, females produce 25-35 eggs per year. Though domesticated breeds of geese generally retain some flight ability, Sebastopols cannot fly well due to the curliness of their feathers and have difficulty getting off the ground. They need plenty of water to keep themselves clean, and to clean their sinuses.
The African or African Goose is a breed of domestic goose. It is one of two domestic breeds that derive from the wild species Anser cygnoides, the other being the Chinese; all other domestic geese derive from Anser anser. Despite the name, it is not from Africa but is of Asiatic origin. It is a large bird, among the heaviest of all goose breeds.
Pilgrim geese is a breed of domestic goose. They are considered to be a relatively quiet, lightweight and medium-sized breed. The pilgrim goose is a rare and critically endangered species according to the American Livestock Breeds Conservancy (ALBC) and was officially entered into the American Poultry Association's Standard of Perfection in 1939. Generally, they can live for 15 to 25 years. In most breeds of geese, males and females are indistinguishable from one another; however, the pilgrim goose is well known for its auto-sexing trait. Males are characterised by white feathers while the females have grey. This sexual dimorphism makes pilgrim geese desirable for breeding as the sexes are easily determined. Their commercial use is primarily limited to the United States where they are bred for eggs and meat. They are known to grow relatively fast and are easy to handle.
The Pomeranian goose, also known as the Rügener goose, is a breed of domestic goose.
The Öland, Swedish: Ölandsgås, is a traditional Swedish breed of domestic goose. It is named for the island of Öland, where it is thought to have originated, and is distributed there, in Småland and in northern Skåne. It is an endangered breed, with few more than a hundred living birds.
Geese are an important motif in Chinese poetry. Examples of goose imagery have an important place in Chinese poetry ranging from the Shijing and the Chu Ci poets through the poets of Han poetry and later poets of Tang poetry such as Li Bai, Wang Wei, Du Fu, and the Xiaoxiang poetry, especially in the poetry of the Song dynastic era. Various poetic concepts could be communicated by the inclusion of the imagery of geese in a poem, and the understanding of allusions to a goose or geese can help provide key insights into the poems of Classical Chinese poetry. Chinese sources typically distinguish between two types of geese, the domestic goose, and the wild goose: of the two, the wild goose is the more important for poetry, whether as significant of migratory seasonal change, or as "bearing a message of love from afar", by persons separated by a great distance, or as the "lone goose", bereft of both mate and flock.
