The turkey is a large bird in the genus Meleagris, native to North America. There are two extant turkey species: the wild turkey of eastern and central North America and the ocellated turkey of the Yucatán Peninsula in Mexico. Males of both turkey species have a distinctive fleshy wattle, called a snood, that hangs from the top of the beak. They are among the largest birds in their ranges. As with many large ground-feeding birds (order Galliformes), the male is bigger and much more colorful than the female. The earliest turkeys evolved in North America over 20 million years ago and they share a recent common ancestor with grouse, pheasants, and other fowl. == Taxonomy == Turkeys are classed in the family Phasianidae (pheasants, partridges, francolins, junglefowl, grouse, and relatives thereof) in the taxonomic order Galliformes. The genus Meleagris is the only extant genus in the subfamily Meleagridinae, formerly known as the family Meleagrididae, but now subsumed within the family Phasianidae. === Extant species === === Fossil species === == History and naming == Turkeys were domesticated in ancient Mexico for food and for their cultural and symbolic significance. The Aztecs, for example, had a name for the turkey, wueh-xōlō-tl (guajolote in Spanish), a word still used in modern Mexico in addition to the general term pavo.
