The domestic turkey, known scientifically as Meleagris gallopavo domesticus, is a large fowl used widely as poultry.

It belongs to the genus Meleagris and shares the same species as the wild turkey. These birds are significant because they provide a large amount of meat for human consumption. Today, they are raised in temperate regions across the globe. This widespread farming is supported by industrialized methods that make turkey meat very inexpensive. While many varieties exist, most modern domestic turkeys descend from birds originally raised in central Mexico.

Understanding the anatomy of a turkey requires looking closely at its unique head features.

A fleshy protuberance located atop the beak is called the snood. Attached to the underside of the beak is a structure known as a wattle. The skin on the head and neck also contains fleshy nodules called caruncles. Adult males often possess a beard, which is a tuft of stiff, black, hair-like feathers on the chest.

These features are not just for looks; they play a role in social displays. During mating displays, males fan their tails and erect their body feathers to attract others.

Domestic turkeys exhibit complex social behaviors and vocalizations. They are highly social animals that become very distressed if they are isolated from a group.

Turkeys use various sounds to communicate social tension within their flock. For example, a high-pitched trill can indicate that the birds are becoming aggressive. This aggression can lead to intense sparring, where opponents leap at each other using sharp talons. They may also attempt to peck or grasp the head of an opponent. These behaviors tend to increase in both frequency and severity as the birds reach maturity.

History shows that humans have interacted with turkeys for thousands of years.

While some domestication likely occurred in central Mesoamerica 2,000 years ago, new research suggests a second event in the southwestern United States between 200 BC and 500 AD. The Aztecs used turkey meat and eggs as primary protein sources. They also used the feathers for decorative purposes. In the 16th century, the Spanish imported turkeys from Mexico to Europe. An English navigator named William Strickland is credited with introducing the bird to England. By 1608, turkeys were being sent from England to Jamestown, Virginia.

There is a wide variety of turkey breeds used for different purposes today. The Broad Breasted White is the primary commercial variety used on large industrial farms. Because it is so common, this breed often receives the "presidential pardon" in the United States. Other varieties include the Broad Breasted Bronze and the single-breasted Standard Bronze. Some heritage breeds are also maintained, such as the Bourbon Red or the Narragansett.

Rare breeds like the Blue Slate turkey have distinct gray-blue feathers. Even more specialized breeds exist, such as the Beltsville Small White, which was introduced in 1941.

Physical size is a major characteristic of the domestic turkey. They are the eighth largest living bird species based on maximum mass.

An average domestic turkey weighs about 13.5 kg (29.8 lb). However, they can reach a maximum mass of 39 kg (86 lb). Their total length usually ranges between 100 and 124.9 cm. Because of this extreme size, domestic turkeys are considered semi-flightless. While younger, smaller specimens can fly short distances, the largest adults are completely terrestrial.

Modern commercial production relies on highly controlled environments to manage large flocks.

In many facilities, birds are raised in large buildings that may contain tens of thousands of individuals. These buildings use artificial lighting to control growth and feeding schedules. To help with temperature regulation, farmers must manage the birds' high metabolic rate. A turkey can have a metabolic rate of up to 69 W per bird. If temperatures become too high, the birds can suffer from heat stress. This management ensures that turkeys remain a steady and affordable food source for people everywhere.
