Wild turkey in the context of Darter

Turkeys are large, heavyset galliforms in the genus Meleagris, indigenous to the Americas. They are among the largest birds in their native ranges, as well as being one of the heaviest birds in the order Galliformes. There are two extant turkey species: the wild turkey (Meleagris gallopavo) of Southern, Central and Eastern North America, and the ocellated turkey (Meleagris ocellata) of the Yucatán Peninsula in Mexico. Males of both species have a distinctive singular fleshy wattle, called a snood, that hangs from the base of the culmen. Like with other phasianines, the male is bigger and sports fancier plumage than the female.

The earliest turkeys evolved in North America over 20 million years ago. They share a recent common ancestor with grouse, pheasants, and other fowl. The North American wild turkey is the ancestor of the domestic turkey, which was domesticated approximately 2,000 years ago by indigenous peoples. It was this domestic descendant that was later transported by humans to Eurasia, during the Columbian exchange.

The domestic turkey (Meleagris gallopavo domesticus) is a large fowl, one of the two species in the genus Meleagris and the same species as the wild turkey. Although turkey domestication was thought to have occurred in central Mesoamerica at least 2,000 years ago, recent research suggests a possible second domestication event in the area that is now the southwestern United States between 200 BC and 500 AD. However, all of the main domestic turkey varieties today descend from the turkey raised in central Mexico that was subsequently imported into Europe by the Spanish in the 16th century.

The domestic turkey is a popular form of poultry. It is raised throughout temperate parts of the world, partially because industrialized farming has made it very cheap for the amount of meat it produces. Female domestic turkeys are called hens, and the chicks are poults or turkeylings. In Canada and the United States, male turkeys are called toms. In the United Kingdom and Ireland, they are stags.

In biology, a rachis /ˈreɪkɪs/ (from the Ancient Greek: ῥάχις [rhákhis], "backbone, spine") is a main axis or "shaft".

Turkey meat, commonly referred to simply as turkey, is the meat from turkeys, typically domesticated ones, but also wild turkeys. It is a popular poultry dish, especially in North America and the United Kingdom, where it is traditionally consumed as part of culturally significant events such as Thanksgiving and Christmas as well as in standard cuisine.

The ocellated turkey (Meleagris ocellata) is a species of turkey residing primarily in the Yucatán Peninsula, Mexico, as well as in parts of Belize and Guatemala. A relative of the North American wild turkey (Meleagris gallopavo), it was sometimes previously considered in a genus of its own (Agriocharis), but the differences between the two turkeys are currently considered too small to justify generic segregation. It is a relatively large bird, at around 70–122 cm (28–48 in) long and an average weight of 3 kg (6.6 lb) in females and 5 kg (11 lb) in males.

The ocellated turkey lives only in a 130,000 km (50,000 sq mi) range in the Yucatán Peninsula in Mexico—which includes all or part of the states of Quintana Roo, Campeche, Yucatán, Tabasco, and Chiapas—as well as the northern and western parts of Belize and northern Guatemala.
