Geographic Range

Wild turkeys (Meleagris gallopavo) are one of the most widely distributed game bird species in North America. They are found throughout most of the eastern United States, and in pockets throughout the western United States. They are also found in parts of northern Mexico, particularly in the Sierra Nevada mountains. Wild turkeys have been introduced to Germany and New Zealand. (Eaton, 1992)

Biogeographic Regions:
nearctic (native ); palearctic (introduced ); australian (introduced ).

Habitat

Wild turkeys prefer hardwood and mixed conifer-hardwood forests with scattered openings such as pastures, fields, orchards and seasonal marshes. (Eaton, 1992)

These animals are found in the following types of habitat:
temperate ; terrestrial .

Terrestrial Biomes:
forest .

Wetlands: marsh .

Physical Description

Mass
3.60 to 11 kg
(7.92 to 24.2 lbs)


Wild turkeys are large, ground-dwelling birds with long legs, long necks and large fan-shaped tails. They have short, rounded wings. Male wild turkeys have dark, iridescent plumage. Their flight feathers are black with brown stripes and are barred with white. They have a red wattle (a fleshy lobe that hangs down from the chin or throat), a caruncle (a wart-like projection of skin attached to the upper part of the forehead), and a blackish breast tuft. Their pink, pinkish-gray, or silver-gray legs have spurs which can grow as long as 3.2 cm. The heads of adult males (called gobblers) are red, blue, or white depending on the season.

Female wild turkeys (called hens) are smaller and duller than males. Most females do not have a breast tuft. Females have a grayish head and a feathered neck.

Male turkeys weigh 6.8 to 11 kg. Hens usually weigh 3.6 to 5.4 kg. Weight varies considerably with time of year and resource availability.

There are six subspecies of Meleagris gallopavo. These subspecies differ in size, plumage and distribution. (Eaton, 1992)

Some key physical features:
endothermic ; bilateral symmetry ; polymorphic .

Sexual dimorphism: male larger, sexes colored or patterned differently, male more colorful, ornamentation .

Reproduction

Wild turkeys breed once per year.

Breeding season
Courtship begins in early spring (January to February).

Eggs per season
4 to 17

Time to hatching
25 to 31 days; avg. 28 days

24 hours (high)

Time to independence
4 to 10 months

Age at sexual or reproductive maturity (female)
10 months (average)

Age at sexual or reproductive maturity (male)
10 months (average)

Wild turkeys are polygynous. Males attempt to attract females by "gobbling" and "strutting" with their tail fanned out, their wings lowered and dragging on the ground, their back feathers erect, their head thrown back and their crop inflated. The gobbles of male wild turkeys can be heard more than 1.5 kilometers away (or approximately 1 mile). (Eaton, 1992)

Mating systems:
polygynous .

Wild turkeys breed in early spring; southern populations begin courtship in late January and northern populations begin in late February. They raise one brood per season. The nest is a shallow depression in the ground, usually surrounded by dense brush, vines, tangles, deep grass, or fallen tree tops. The female scratches out the nest and lays 4 to 17 (usually 8 to 15) eggs. She incubates the eggs for 25 to 31 days. The chicks are precocial, and are able walk and feed themselves within 24 hours of hatching. The female broods the chicks at night for the first 2 weeks after hatching. She also defends them from predators, sometimes pursuing hawks or other predators. The young turkeys (called poults) stay with the female parent through the fall (males) or the early spring (females). Turkeys are capable of breeding at about 10 months old, though young males are typically not successful in competing with older males for mates during their first spring.

Egg dumping (laying eggs in another female's nest) is common in this species. This species is also known to lay eggs in the nests of ruffed grouse. Ring-necked pheasants are known nest parasites of wild turkeys. (Eaton, 1992)

Key reproductive features:
iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous .

Male wild turkeys do not provide any parental care. Female wild turkeys prepare the nest, incubate the eggs, and care for the young until the next spring (fall for male poults). The chicks are precocial, and are able to walk and feed themselves within 24 hours of hatching. (Eaton, 1992)

Parental investment:
no parental involvement; precocial ; pre-fertilization (provisioning, protecting: female); pre-hatching/birth (protecting: female); pre-weaning/fledging (protecting: female); pre-independence (protecting: female).

Lifespan/Longevity

The average life expectancy for wild turkeys is estimated at 1.3 to 1.6 years. The oldest known wild turkey lived at least 13 years. (Eaton, 1992)

Behavior

Wild turkeys are diurnal and non-migratory. By day, they can be seen grazing in fields and woodlands. At night, they roost in trees.

Wild turkeys are generally wary, and have keen eyesight and hearing. They are swift runners and fast fliers. Turkeys have been recorded flying at 88.5 km/h.

Turkeys are social. During the winter, they form bands in which dominance hierarchies may develop. In some populations, each band may defend a territory against other bands. (Eaton, 1992)

Home Range

We do not have information on home range of this species at this time.

Key behaviors:
terricolous; flies; diurnal ; motile ; sedentary ; social ; dominance hierarchies .

Communication and Perception

Wild turkeys use vocalizations and physical displays to communicate. For example, during the spring, males will fan out their tails, strut and "gobble" in an attempt to attract and retain a harem of females. Biologists recognize at least 15 different wild turkey vocalizations, including the widely recognized "gobble". The "gobble" is give primarily by males with the purpose of attracting females and repelling competing males. Other vocalizations are used by both sexes to communicate a variety of messages. (Eaton, 1992)

Communicates with:
visual ; acoustic .

Perception channels:
visual ; tactile ; acoustic ; chemical .

Food Habits

Wild turkeys are omnivorous. They primarily eat vegetable matter such as acorns, nuts, seeds, buds, leaves and fern fronds. They also eat ground-dwelling insects and salamanders, which account for about 10% of their diet. Wild turkeys forage primarily on the ground, though they occasionally mount shrubs and low trees to reach fruits and buds. Most foraging occurs during the 2 to 3 hours after dawn and before dusk. (Eaton, 1992)

Primary Diet:
omnivore .

Animal Foods:
amphibians; insects.

Plant Foods:
leaves; roots and tubers; seeds, grains, and nuts; fruit.

Predation

Predators of wild turkey eggs and nestlings include raccoons, opossums, striped skunks, grey foxes, birds, woodchucks, rodents, spotted skunks, bobcats, rat snakes and bull snakes.

Humans are the primary predator of adult wild turkeys. Other predators include coyotes, bobcats, raccoons, mountain lions, golden eagles, and great horned owls. (Eaton, 1992)

Ecosystem Roles

Wild turkeys provide food for their predators and impact populations of the plants whose seeds and nuts they eat.

Wild turkeys also host at least 60 different species of parasites. These include 9 protozoans, 11 trematodes, 10 cestodes, 1 acanthocephalan, 17 nematodes and 12 arthropods. (Eaton, 1992)

Economic Importance for Humans: Negative

There are no known adverse effects of wild turkeys on humans.

Economic Importance for Humans: Positive

Wild turkeys are one of the most popular game bird species in the United States. Turkey hunting brings millions of dollars to states' Departments of Natural Resources, as well as to public and private organizations each year. Conservation efforts may benefit from turkey hunting through habitat improvement projects. Numerous organizations work to keep wild turkeys plentiful throughout the country.

Ways that people benefit from these animals:
food .

Conservation Status

IUCN Red List: [link]:
Least Concern.

US Migratory Bird Act: [link]:
No special status.

US Federal List: [link]:
No special status.

CITES: [link]:
No special status.

State of Michigan List: [link]:
No special status.

Wild turkeys are plentiful and are widespread. Many states are starting to introduce them into previously uninhabited areas, increasing their range and distribution. Current estimates of wild turkey populations are around 4 million in North America (Dickson, 1995).

Wild turkeys are not legally protected. In fact, they are hunted in many states.
