The turkey is a large bird in the Meleagris genus, which is native to the Americas. One species, Meleagris gallopavo (commonly known as the Wild Turkey), is native to the forests of North America. The domestic turkey is a descendant of this species. The other living species is Meleagris ocellata or the Ocellated Turkey, native to the forests of the Yucatán Peninsula.
Turkeys are classed in the taxonomic order of Galliformes where they are relatives of the grouse. 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 (tom or gobbler) is larger and much more colorful than the female (hen). A baby turkey is known as a poult. The Meleagris genus is the only genus in the Meleagridinae subfamily, formerly known as the Meleagrididae family but now subsumed within the Phasianidae family.
History and naming
When Europeans first encountered turkeys in America, they incorrectly identified the birds as a type of guineafowl (Numididae). Guinea-fowl were also known as turkey fowl (or turkey hen and turkey cock) because they were imported to Central Europe through Turkey. The name turkey fowl, shortened to just the name of the country, stuck as the name of the North American bird. 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 confusion between these kinds of birds from related but different families is also reflected in the scientific name for the turkey genus: meleagris (μελεαγρίς) is Greek for guineafowl. Two major reasons why the name 'turkey fowl' stuck to Meleagris rather than to the Helmeted Guineafowl (Numida meleagris), were: a) the genuine belief that the newly discovered America was in fact a part of Asia, and b) the tendency during that time of attributing exotic animals and foods to places that symbolized far-off, exotic lands.
In many countries, the name for turkeys has a different derivation (see List of names for the Wild Turkey).
Several other birds that are sometimes called turkeys are not particularly closely related: the Australian Brushturkey is a megapode, and the bird sometimes known as the "Australian Turkey" is the Australian Bustard, a gruiform. The Anhinga (Anhinga rufa) 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 of climate change at the end of the last glacial period and hunting.

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 Phasianidae family. In 2010, a team of scientists published a draft sequence of the domestic turkey (Meleagris gallopavo) genome.
