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.
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 .
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 species for which information is known are normally monogamous, mating for life, or are serially monogamous; however, occasional exceptions have been recorded for helmeted and Kenya crested guineafowl, which have been reported to be polygamous in captivity. [4] All guineafowl are social, and typically live in small groups or large flocks.
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.
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.
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]
