Galliformes /ˌɡælɪˈfɔːrmiːz/ is an order  of heavy-bodied ground-feeding birds  that includes turkeys, chickens, quail, and other landfowl. Gallinaceous birds, as they are called, are important in their ecosystems as seed dispersers and predators, and are often reared by humans for their meat and eggs, or hunted as game birds.
