Adult males are very large and dark with a bare, red and blue head, with red wattles on the throat and neck. They have long legs. The feathers are bronzy and iridescent. Males, and some females, have a tuft of hairlike feathers (called a “beard”) in the middle of the breast. Females are smaller and less iridescent. Turkeys are most famous for their gobbling calls, but they make many other vocalizations as well.
