Galliformes / ˌ ɡ æ l ɪ ˈ f ɔːr m iː z / 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.
Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl (Galliformes) and the waterfowl (Anseriformes).Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae or Galloanseres (initially termed Galloanseri) (Latin gallus ("rooster") + ānser ...
The Galliformes are a clade of bird species of cosmopolitan distribution that, with the Anseriformes, belong to the branch Galloanserae. The group have more than 270 living species and includes the megapodes , chachalacas , guans , curassows , turkeys , grouse , New World quails , pheasants , partridges and guineafowl .
The clade Phasianidae is the largest of the branch Galliformes, comprising 185 species divided into 54 genera. [3] This group includes the pheasants and partridges, junglefowl chickens, quail, and peafowl.
Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia.One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved.

This is a list of Galliformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology.
An amateur fossil hunter has uncovered a piece of animal vomit which dates back 66 million years on a beach in Denmark.
The nonsocial nature of their incubation raises questions as to how the hatchlings come to recognise other members of their species, which is due to imprinting in other members of the order Galliformes. Research suggests an instinctive visual recognition of specific movement patterns is made by the individual species of megapode. [7]
