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.
Name
The name turkey originated as a shortening of turkey cock and turkey hen and initially denoted the guineafowl, an African bird to which the turkeys of North America are only distantly related. Guineafowl were first imported to Europe via Turkey, hence the name. Following the establishment of English colonies in the New World, the name was transferred to the superficially similar North American bird. In languages such as French, the bird was named after India. The bird was originally called poule d'inde or chicken of India later becoming dinde. In languages in Northern Europe such as Norwegian, Swedish, and Estonian, the bird was named after Calicut, India (now Kozhikode, India). 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". 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 was already widespread. An infant turkey is called a chick or poult.
Taxonomy The genus Meleagris was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. The genus name is from the Ancient Greek μελεαγρις, meleagris meaning "guineafowl". The type species is the wild turkey (Meleagris gallopavo). Turkeys are classed in the family Phasianidae (pheasants, partridges, francolins, junglefowl, grouse, and relatives thereof) in the taxonomic order Galliformes. They are close relatives of the grouse and are classified alongside them in the tribe Tetraonini.
Extant species The genus contains two species.
Fossil species Meleagris californica Californian turkey – Southern California Meleagris crassipes Southwestern turkey - New Mexico
History
Turkeys were likely first domesticated in Pre-Columbian Mexico, where they held a cultural and symbolic importance. The Classical Nahuatl word for the turkey, huehxōlō-tl (guajolote in Spanish), is still used in modern Mexico, in addition to the general term pavo. Mayan aristocrats and priests appear to have had a special connection to ocellated turkeys, with ideograms of those birds appearing in Mayan manuscripts. Spanish chroniclers, including Bernal Díaz del Castillo and Father Bernardino de Sahagún, describe the multitude of food (both raw fruits and vegetables as well as prepared dishes) that were offered in the vast markets (tianguis) of Tenochtitlán, noting there were tamales made of turkeys, iguanas, chocolate, vegetables, fruits and more. Turkeys were first exported to Europe via Spain around 1519, where they gained immediate popularity among the aristocratic classes. Turkeys arrived in England in 1541. From there, English settlers brought turkeys to North America during the 17th century.
Destruction and re-introduction in the United States In what is now the United States, there were an estimated 10 million wild turkeys in the 17th century. By the 1930s, only 30,000 remained. In the 1960s and 1970s, biologists started trapping wild turkeys from the few places they remained (including the Ozarks and New York), and re-introducing them into other states, including Minnesota and Vermont. Starting in 2014, researchers sent a survey to wildlife biologists in the National Wild Turkey Federation Technical Committee across the U.S. states to gather data regarding the population of turkeys. As of 2019, the wild turkey population declined by around 3% since 2014. Also as of 2019, the number of wild turkey hunters decreased by 18% since 2014 from the reports of the participating U.S. states. The 2019 data for population was missing information from 12 states and the 2019 hunter data was missing information from 8 states.
Human conflicts with wild turkeys Turkeys have been known to be aggressive toward humans and pets in residential areas. Wild turkeys have a social structure and pecking order and habituated turkeys may respond to humans and animals as they do to other turkeys. Habituated turkeys may attempt to dominate or attack people that the birds view as subordinates. In Brookline, Massachusetts, the 30,000 turkeys have become so prominent that they are considered to be the town's unofficial mascot. While some residents find them charming, others have experienced problems with aggressive behavior, particularly during mating season. Brookline has even installed turkey statues around town as part of a public art project. In 2017, Brookline recommended a controversial approach when confronted by wild turkeys. Besides taking a step forward to intimidate the birds, officials also suggested "making noise (clanging pots or other objects together); popping open an umbrella; shouting and waving your arms; squirting them with a hose; allowing your leashed dog to bark at them; and forcefully fending them off with a broom". This advice was quickly rescinded and replaced with a caution that "being aggressive toward wild turkeys is not recommended by State wildlife officials".
