Wild turkey

The wild turkey (Meleagris gallopavo) is a large upland game bird native to North America.

It is the heaviest member of the order Galliformes, a group of birds that includes chickens and pheasants. This wild species is also the direct ancestor of the domestic turkey (M. g. domesticus). While the domestic version comes from a southern Mexican subspecies, the wild turkey remains a powerful and agile flyer. In fact, it is among the heaviest flying birds in the world.

Only the trumpeter swan has a higher maximum average weight in North America.

Scientists have used specific names to describe this bird for centuries. The Swedish naturalist Carl Linnaeus formally described the species in 1758. He placed it in his tenth edition of Systema Naturae. The genus name, Meleagris, comes from the Ancient Greek word for guineafowl. The specific name, gallopavo, is a late Medieval Latin term. It combines the Latin words gallus, meaning fowl, and pavo, meaning peacock. The Swiss naturalist Conrad Gessner used this name as early as 1555.

Wild turkeys show strong sexual dimorphism, meaning males and females look very different.

Adult males, often called toms or gobblers, are substantially larger than females, known as hens. An average male weighs about 18 pounds, while an average female weighs about 11 pounds. Males have dark feathers with an iridescent sheen of red, purple, green, copper, and gold. They also grow a "beard," which is a tuft of coarse, hair-like filaments called mesofiloplumes. About 10% of females also have these beards, though they are usually thinner.

Females have much duller feathers in shades of brown and gray. This helps them stay camouflaged while nesting. The males have unique fleshy growths on their heads called caruncles. They also have a fleshy flap on their bill known as a snood. When a male is excited, his blood flow increases to his head. This causes the snood, the wattles, and the bare skin to turn bright red.

Even their internal biology differs, as males have a larger preen gland, or uropygial gland.

There are six recognized subspecies of the wild turkey.

These include the South Mexican wild turkey, the Rio Grande wild turkey, and Merriam's wild turkey. Other types are the Gould's wild turkey, the Florida wild turkey, and the Eastern wild turkey. These birds live in many habitats. They prefer hardwood and mixed conifer-hardwood forests with open spaces like pastures or orchards. In California, they often live in oak woodlands. In Florida, they can be found in cypress and tupelo swamps.

Wild turkeys are omnivores, meaning they eat both plants and animals. They forage on the ground for acorns, nuts, seeds, berries, and leaves. They also eat insects and can even consume small reptiles like lizards or snakes.

They are very social and use many vocalizations. Males use a loud "gobble" to announce themselves, which can be heard up to a mile away. They also produce a low-pitched drumming sound by moving air in a chest air sac. At night, they fly to high tree branches to roost. This protects them from predators that hunt in the dark.

Social behavior is very important for mating and survival. During courtship in March and April, males perform a behavior called strutting. They puff out their feathers, spread their tails, and drag their wings to attract females.

Interestingly, males sometimes court in pairs. Research shows that a dominant male courting with a partner may father six more eggs than a male courting alone. This team-courtship often involves close relatives who share half of their genetic material. This behavior helps both birds pass on their shared genes to the next generation.
