Temporal range: 23–0 Ma Early Miocene – Recent
The turkey is a large bird in the genus Meleagris, which is native to the Americas. One species, Meleagris gallopavo (commonly known as the domestic turkey or wild turkey), is native to the forests of North America, mainly Mexico and the United States. The other living species is Meleagris ocellata or the ocellated turkey, native to the forests of the Yucatán Peninsula. Males of both turkey species have a distinctive fleshy wattle or protuberance that hangs from the top of the beak (called a snood). They are among the largest birds in their ranges. As in many galliformes, the male is larger and much more colorful than the female.
Turkeys are classed in the family of Phasianidae (pheasants, partridges, francolins, junglefowl, grouse and relatives) in the taxonomic order of Galliformes. The genus Meleagris is the only genus in the subfamily Meleagridinae, formerly known as the family Meleagrididae, but now subsumed within the family Phasianidae.
History and naming
||This section appears to contradict itself about the origin of the name. (October 2015)|
When Europeans first encountered turkeys in America, they incorrectly identified the birds as a type of guineafowl – i.e., as members of a group of birds which were thought to typically come from the country of Turkey. The name of the North American bird thus became "turkey fowl", which was then shortened to just "turkey". In 1550, the English navigator William Strickland, who had introduced the turkey into England, was granted a coat of arms including a "turkey-cock in his pride proper".
The birds came to England via merchant ships from the Middle East where they were domesticated successfully. These merchants were called "Turkey merchants" as much of the area was part of the Ottoman Empire. Hence the name “Turkey birds” or, soon thereafter, “turkeys”. William Shakespeare used the term in Twelfth Night, believed to be written in 1601 or 1602. The lack of context around his usage suggests that the term had widespread reach.
In many countries, the names for turkeys have different derivations.
Several other birds that are sometimes called turkeys are not particularly closely related: the brushturkeys are megapodes, and the bird sometimes known as the "Australian turkey" is the Australian bustard (Ardeotis australis). The anhinga (Anhinga anhinga) is sometimes called a water turkey, from the shape of its tail when the feathers are fully spread for drying.
A number of turkeys have been described from fossils. The Meleagridinae are known from the Early Miocene (c. 23 mya) onwards, with the extinct genera Rhegminornis (Early Miocene of Bell, U.S.) and Proagriocharis (Kimball Late Miocene/Early Pliocene of Lime Creek, U.S.). The former is probably a basal turkey, the other a more contemporary bird not very similar to known turkeys; both were much smaller birds. A turkey fossil not assignable to genus but similar to Meleagris is known from the Late Miocene of Westmoreland County, Virginia. In the modern genus Meleagris, a considerable number of species have been described, as turkey fossils are robust and fairly often found, and turkeys show great variation among individuals. Many of these supposed fossilized species are now considered junior synonyms. One, the well-documented California turkey Meleagris californica, became extinct recently enough to have been hunted by early human settlers. It is believed its demise was due to the combined pressures caused by hunting and by climate change at the end of the last glacial period.

Turkeys have been considered by many authorities to be their own family—the Meleagrididae—but a recent genomic analyses of a retrotransposon marker groups turkeys in the family Phasianidae. In 2010, a team of scientists published a draft sequence of the domestic turkey (Meleagris gallopavo) genome.
Use by humans
|This section requires expansion. (December 2015)|
The species Meleagris gallopavo is used by humans for their meat. However, they were first domesticated by Native Americans from 800BC onwards for their feathers, which were used in ceremonies and to make robes and blankets. Turkeys were first used for meat by Native Americans in around 1100AD. Compared to wild turkeys, domestic turkeys are selectively bred to grow larger in size for their meat. Humans normally eat turkeys on special occasions such as at Thanksgiving or Christmas. Properly roasting a turkey is an intense process that is sometimes augmented with other meats into elaborate dishes known as turducken. Vegetarian analogues made from tofu are known as tofurkey, while tofurky is a specific turkey alternative product that is a trademark of Oregon-based Turtle Island Foods.
The Norfolk turkeys
In the written memoirs of Lady Dorothy Nevill she recalls that her great-grandfather Horatio Walpole, 1st Earl of Orford imported a quantity of the American turkeys which were kept in the woods around Wolterton and in all probability were the embryo flock for the popular Norfolk turkey breeds of today.
