An adult male domestic turkey is commonly called a tom.
The word “tom” is a standard name for a male turkey, especially in farming and poultry writing. An adult female is a hen, while a young turkey is generally called a poult. These names are distinct from chicken terminology: a male chicken is a rooster or cock, and a female chicken is a hen.
Domestic turkeys descend from the wild turkey, a species native to North America. European colonists encountered wild turkeys and later developed domesticated strains that became important poultry. Modern domestic turkeys are generally heavier and less capable of sustained flight than wild turkeys.
The male’s display includes spreading the tail, lowering the wings, and puffing out the body feathers. The fleshy structures on the head and neck are especially conspicuous during display. Turkey vocabulary can vary by region, but “tom” is the canonical common term for an adult male.
