Galliformes are an order of birds containing turkeys, grouse, chicken, quail, and pheasants. Common names are gamefowl or gamebirds, landfowl, gallinaceous birds or galliforms. "Wildfowl" or just "fowl" are also often used for Galliformes, but usually these terms also refer to waterfowl (Anseriformes), and occasionally to other commonly-hunted birds.
They are heavy-bodied ground-feeding domestic or game birds, including grouse, ptarmigan, pheasant, partridge, chachalaca, and curassow – all in the order Galliformes.
This group has more than 250 living species, one or more of which are found in essentially every part of the world's continents (except for the innermost deserts and perpetual ice). They are more rare on islands, and in contrast to the closely-related waterfowl are essentially absent from oceanic islands—except if introduced there by humans. Several species have been domesticated during their long and extensive relationship with humans.
