A variant of Domestic turkey (Meleagris gallopavo)

Old solid-black European heritage breed with a green sheen; cold-hardy, calm, and a parent breed of several American varieties.
Keeper tips for this variant
Very cold-hardy and docile, but the black head/wattles still frostbite — keep the coop dry and draft-free in winter rather than heated, and house away from chickens.
