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, which was originally derived from a southern Mexican subspecies of wild turkey (not the related ocellated turkey).
Description: An adult male (tom or gobbler) normally weighs from 5 to 11 kg (11 to 24 lb) and measures 100–125 cm (39–49 in) in length. The adult female (hen) is typically much smaller at 2.5–5.4 kg (5.5–11.9 lb) and is 76 to 95 cm (30 to 37 in) long.Per two large studies, the average weight of adult males is 7.6 kg (17 lb) and the average weight of adult females is 4.26 kg (9.4 lb). The record-sized adult male wild turkey, according to the National Wild Turkey Federation, weighed 16.85 kg (37.1 lb), with records of tom turkeys weighing over 13.8 kg (30 lb) uncommon but not rare.
The wings are relatively small, as is typical of the galliform order, and the wingspan ranges from 1.25 to 1.44 m (4 ft 1 in to 4 ft 9 in). The wing chord is only 20 to 21.4 cm (7.9 to 8.4 in). The bill is also relatively small, as adults measure 2 to 3.2 cm (0.79 to 1.26 in) in culmen length. The tarsus of the wild turkey is quite long and sturdy, measuring from 9.7 to 19.1 cm (3.8 to 7.5 in). The tail is also relatively long, ranging from 24.5 to 50.5 cm (9.6 to 19.9 in).
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.
Habitat: Eastern subspecies
Wild turkeys prefer hardwood and mixed conifer-hardwood forests with scattered openings such as pastures, fields, orchards and seasonal marshes. They seemingly can adapt to virtually any dense native plant community as long as coverage and openings are widely available. Open, mature forest with a variety of interspersion of tree species appear to be preferred. In the Northeast of North America, turkeys are most profuse in hardwood timber of oak-hickory (Quercus-Carya) and forests of red oak (Quercus rubra), beech (Fagus grandifolia), cherry (Prunus serotina) and white ash (Fraxinus americana). Best ranges for turkeys in the Coastal Plain and Piedmont sections have an interspersion of clearings, farms, and plantations with preferred habitat along principal rivers and in cypress (Taxodium distichum) and tupelo (Nyssa sylvatica) swamps.
Behavior:
Flight: Despite their weight, wild turkeys, unlike their domesticated counterparts, are agile, fast fliers. In ideal habitat of open woodland or wooded grasslands, they may fly beneath the canopy top and find perches. They usually fly close to the ground for no more than 400 m (a quarter mile).
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.
Vocalizations: Wild turkeys have many calls: assembly call, gobble, plain yelp, purr, cluck and purr, cluck, cutt, excited yelp, fly-down cackle, tree call, kee kee run, and putt. In early spring, males older than a year old and, occasionally to a lesser extent, males younger than a year old gobble to announce their presence to females and competing males. The gobble of a wild turkey can be heard up to a mile away.[citation needed] Males also emit a low-pitched “drumming” sound, produced by the movement of air in the air sac in the chest, similar to the booming of a prairie chicken. In addition they produce a sound known as the “spit”, which is a sharp expulsion of air from this air sac.
