The wild turkey ( Meleagris gallopavo) is an upland game bird native to North America, one of two extant species of turkey and the heaviest member of the order Galliformes. It is the ancestor to the domestic turkey ( M. g. domesticus), which was originally derived from a southern Mexican subspecies of wild turkey (not the related ocellated turkey).
Six subspecies are recognised:
The wings are relatively small, as is typical of the galliform order, and the wingspan ranges from . The wing chord is only . The Beak is also relatively small, as adults measure in culmen length. The Tarsometatarsus of the wild turkey is quite long and sturdy, measuring from . The tail is also relatively long, ranging from .
Fully-grown wild turkeys have long, reddish-yellow to grayish-green legs. Each foot has three front toes, with a shorter, rear-facing toe; males have a spur behind each of their lower legs, used to spar with other males.
The body feathers are generally blackish and dark, sometimes gray-brown, overall, with a coppery sheen that becomes more complex in older males. Mature males have a large, featherless, reddish head and red throat, with red wattles on the throat and neck. The head has fleshy, unique growths called caruncles, which may be used to identify certain birds from one another. When toms are excited, a fleshy flap on the bill (called a snood) expands, and this, the wattles and the bare skin of the head and neck all become red with enhanced flow of blood to the head. Tail feathers are of the same length in adults but of different lengths in juveniles.
Males have a long, dark, fan-shaped tail and glossy, bronze wings. As with many other species of Galliformes, turkeys exhibit strong sexual dimorphism. The male is substantially larger than the female, and his feathers have areas of red, purple, green, copper, bronze, and gold Iridescent. The preen gland (uropygial gland) is also larger in males compared to females. In contrast to the majority of other birds, they are colonized by bacteria of unknown function ( Corynebacterium uropygiale). Males typically have at least one "beard", a tuft of coarse hair-like filaments (mesofiloplumes), growing from the center of the breast. Beards grow continuously during the turkey's lifespan and a one-year-old male has a beard up to long. Approximately 10% of females have a beard, usually shorter and thinner than that of the male.
Females have feathers that are duller overall, in shades of brown and gray. Parasites can dull the coloration of both sexes; in males, vivid coloration may serve as a signal of health. The primary wing feathers have white bars. Turkeys have approximately 5,000 to 6,000 feathers. Juvenile males are called jakes; the difference between jakes and toms is that jakes have very short "beards" and tail fans with longer feathers in the middle. The tom's tail fan feathers are uniform in length.
The turkey has the second-highest maximum average weight of any North American bird, after the trumpeter swan ( Cygnus buccinator). By average mass, however, several other American birds surpass the mean weight of the turkey, including the American white pelican ( Pelecanus erythrorhynchos), the tundra swan ( Cygnus columbianus columbianus), the endangered California condor ( Gymnogyps californianus), and whooping crane ( Grus americana).
In the Appalachian Plateau and Cumberland Plateau birds occupy mixed forest of oaks and pines on southern and western slopes, also hickory with diverse understories. Bald cypress and sweet gum ( Liquidambar styraciflua) swamps of south Florida; also hardwood of Cliftonia (a heath) and oak in north-central Florida. Lykes Brothers Fisheating Creek area of south Florida has up to 51% cypress, 12% hardwood hammocks, 17% glades of short grasses with isolated live oak ( Quercus virginiana); nesting in neighboring prairies. Original habitat here was mainly longleaf pine ( Pinus palustris) with turkey oak ( Quercus laevis) and slash pine ( Pinus elliottii) "flatwoods", now mainly replaced by slash pine plantations.
In California, turkeys live in a wide range of habitats; are a favorite food, in addition to wild oats ( Avena barbata), drawing turkeys to areas of open oak forest and oak savanna across the central areas of the state. They frequent the lower-elevation oak woodlands of the Sierra Nevada foothills and Coast Ranges, and the central coast north through Mendocino County, which is primarily open conifer forest with various species of ferns growing in the understory. They can also be found in the conifer foothills and fern-heavy forested areas of the Klamath Mountains and Cascade Range in the northern areas of the state. In San Diego County, turkeys tend to be found farther from the coast, usually a minimum of 30–50 miles inland, at reasonably higher elevation; there is a healthy turkey population inhabiting the montane conifer woods and open oak forest habitats of the Cleveland National Forest, a region which borders on high desert and generally receives very minimal annual precipitation. Turkeys in these areas can be found in dense thickets of manzanita ( Arctostaphylos), often growing on arid hillsides, for shelter and nesting sites, as well as rocky and boulder-strewn chaparral foothills.
Wild turkeys have very good eyesight, but their vision is very poor at night. They will generally not see a predator until it is too late. At twilight most turkeys will head for the trees and roost well off the ground: it is safer to sleep there in numbers than to risk being victim to predators who hunt by night. Because wild turkeys do not migrate, in snowier parts of the species's habitat like the Northeast, Rockies, much of Canada, and the Midwest, it is very important for this bird to learn to select large conifer trees where they can fly onto the branches and shelter from blizzards.
Males may be seen courting in groups, often with the dominant male gobbling, spreading his tail feathers (strutting), drumming/booming, and spitting. In a study, the average dominant male that courted as part of a pair of males fathered six more eggs than males that courted alone. Genetic analysis of pairs of males courting together shows that they are close relatives, with half of their genetic material being identical. The theory behind team-courtship is that the less-dominant male has a greater chance of passing along shared genetic material than if he were courting alone.
When mating is finished, females search for nest sites. Nests are shallow dirt depressions engulfed with woody vegetation. Hens lay a clutch of 10–14 eggs, usually one per day. The eggs are incubated for at least 28 days. The poults are precocial and nidifugous, leaving the nest in about 12–24 hours. Turkeys are a ground nesting bird, and because of this they are heavily predated on; reproductively-active wild turkeys have a lower annual survival rate due to predation of nests.
Avian predators of poults include raptors such as ( Haliaeetus leucocephalus), barred owl ( Strix varia), red-shouldered ( Buteo lineatus), red-tailed hawk ( Buteo jamaicensis), white-tailed ( Geranoaetus albicaudatus), Harris's hawks ( Parabuteo unicinctus), Cooper's hawk ( Accipiter cooperii), and broad-winged hawk ( Buteo platypterus) (both likely of very small poults). Mortality of poults is greatest in the first 14 days of life, especially of those roosting on the ground, decreasing most notably after half a year, when they attain near adult sizes.
In addition to poults, hens and adult-sized fledglings (but not, as far as is known, adult male toms) are vulnerable to predation by great horned owls ( Bubo virginianus), American goshawk ( Accipiter atricapillus), dog ( Canis familiaris), cat ( Felis catus), and ( Vulpes vulpes). Predators of both adults and poults include ( Canis latrans), gray wolf ( Canis lupus), ( Lynx rufus), ( Puma concolor), Canada lynx ( Lynx canadensis) , ( Aquila chrysaetos), and possibly American black bears ( Ursus americanus), which also will eat the eggs if they find them. The American alligator ( Alligator mississippiensis) is a predator to all turkeys of all ages in the Southeast and will eat them if they get too close to water. Humans are now the leading predator of adult turkeys.Kennamer, James Earl. Predators and Wild Turkeys . NWTF Wildlife Bulletin NO.16 When approached by potential predators, turkeys and their poults usually run rather than fly away, though they may also fly short distances if pressed. Another alternative behaviour, common in Galliformes, is that when surprised with no time to flee, the poulets hide under the wings and body of the hen while she sits tight and still. Presumably, the hen has vocal and behavioural signals that trigger the poults to instinctively run to the hen for cover.
Occasionally, if cornered, adult turkeys may try to fight off predators and large male toms can be especially aggressive in self-defense. When fighting off predators, turkeys may kick with their legs, using the spurs on their back of the legs as a weapon, bite with their beak, and ram with their relatively large bodies and may be able to deter predators up to the size of mid-sized mammals. Wild Turkey Predators, Wild Turkey Predation: National Wild Turkey Federation . Nwtf.org. Retrieved on 2012-12-19. Wild Turkey Predators . Waterandwoods.net (2008-09-20). Retrieved on 2012-12-19. Hens have been observed chasing off at least two species of hawks in flight when their poults are threatened.
Wild turkeys are not usually aggressive towards humans, but can be frightened or provoked to behave with aggression. They are most likely to attack if startled, cornered, harassed, or if approached too closely. Attacks and potential injuries can usually be avoided by giving wild turkeys a respectful amount of space and keeping outdoor spaces clean and undisturbed.

Also, turkeys that are habituated to seeing people, at places like parks or campgrounds, can be tame and will even feed from the hands of people. Male toms occasionally will attack parked cars and reflective surfaces, thinking they see another turkey and must defend their territory.
Game managers estimate that the entire population of wild turkeys in the United States was as low as 30,000 by the late 1930s. By the 1940s, it was almost totally extirpated from Canada and had become localized in pockets in the United States, in the north-east effectively restricted to the Appalachians, only as far north as central Pennsylvania. Early attempts used hand-reared birds, a practice that failed miserably as the birds were unable to survive in the wild at all and many had imprinted far too much on humans to effectively survive. Game officials later made efforts to protect and encourage the breeding of the surviving wild population. They would wait for numbers to grow, catch the surplus birds with a device that would have a projectile net that would ensnare the creature, move it to another unoccupied territory, and repeat the cycle. Over time this included some in the western states where it was not native. There is evidence that the bird does well when near farmland, which provides grain and also berry-bearing shrubs at its edges. As wild turkey numbers rebounded, hunting became legal in 49 U.S. states (excluding Alaska). In 1973, the total U.S. population was estimated to be 1.3 million, and current estimates place the entire wild turkey population at 7 million individuals. Since the 1980s, "trap and transfer" projects have reintroduced wild turkeys to several provinces of Canada as well, sometimes from across the border in the United States. They appear to be very successful as of 2018 as wild turkeys have multiplied rapidly and flourished in places where they were not expected to survive by Canadian scientists, often quite far north of their original expected range.
Attempts to introduce the wild turkey to Great Britain as a game bird in the 18th century were unsuccessful. George II is said to have kept a flock of a few thousand in Richmond Park near London, but they were too easy for local poaching to steal, and the fights with poachers became too dangerous for the . They were hunted with dogs and then shot out of trees where they took refuge. Several other populations, introduced or escaped, have survived for periods elsewhere in Britain and Ireland, but seem to have died out, perhaps from a combination of lack of winter feed and poaching. Small populations, probably descended from farm as well as wild stock, in the Czech Republic and Germany have been more successful, and there are wild populations of some size following introductions in Hawaii and New Zealand.
The Californian turkey ( Meleagris californica) is an extinct species of turkey indigenous to the Pleistocene and early Holocene of California. It became extinct about 10,000 years ago. The present Californian wild turkey population derives from wild turkeys introduced to the region during the 1960s and 1970s from other areas by game officials.California Department of Fish and Game. Wild Turkey Guide 2005 . They proliferated after 2000 to become an everyday sight in the East Bay by 2015.
Franklin never publicly voiced opposition to the bald eagle as a national symbol, nor did he ever publicly suggest the turkey as a national symbol. The story has been called a myth.
Significant peoples of several tribes, including Muscogee Creek and Wampanoag people, wore turkey feather cloaks. The turkey clan is one of the three Lenape clans. Movements of wild turkeys inspired the Caddo tribe's turkey dance. The Navajo people of Northeastern Arizona, New Mexico and Utah call the turkey Tązhii and relate the bird to the corn and seeds which The Turkey in Navajo folklore brought from the Third Navajo World. It is one of the Navajos' sacred birds, with the Navajo people using the feathers and parts in multiple traditional ceremonies.
