Wild turkey in the context of "Ocellated turkey"

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 darters, anhingas, or snakebirds are mainly tropical waterbirds in the family Anhingidae, which contains a single genus, Anhinga. There are four living species, three of which are very common and widespread while the fourth is rarer and classified as near-threatened by the IUCN. The term snakebird is usually used without any additions to signify whichever of the completely allopatric species occurs in any one region. It refers to their long thin neck, which has a snake-like appearance when they swim with their bodies submerged, or when mated pairs twist it during their bonding displays. "Darter" is used with a geographical term when referring to particular species. It alludes to their manner of procuring food, as they impale fishes with their thin, pointed beak. The American darter (A. anhinga) is more commonly known as the anhinga. It is sometimes called "water turkey" in the southern United States; though the anhinga is quite unrelated to the wild turkey, they are both large, blackish birds with long tails that are sometimes hunted for food.
