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 .
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.
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.

Grouse / ɡ r aʊ s / are a group of birds from the order Galliformes, in the family Phasianidae.Grouse are presently assigned to the tribe Tetraonini (formerly the subfamily Tetraoninae and the family Tetraonidae), a classification supported by mitochondrial DNA sequence studies, [2] and applied by the American Ornithologists ...
In megapodes superprecociality apparently evolved secondarily from brooding and at least loose parental care as more typical in Galliformes. [8] Eggs previously assigned to Genyornis have been reassigned to giant megapode species. Some dietary and chronological data previously assigned to dromornithids may instead be assigned to the giant ...
It is a comparatively large for megapodes with some noticeable sexual dimorphism. Adults are on average, 46 cm long with a weight between 1.2 and 1.6 kg. [2] Females have a dull grey bare facial skin, whereas the males are pale-blue. Moreover, the red wattles on the head and chest is enlarged in the male, whilst it is reduced for females.
The sand partridge is one of 185 species in the ground-living family Phasianidae, the most-species rich clade in the Galliformes order. [4] The Phasianidae family has a subfamily Phasianinae, which was considered monophyletic up until the 1990s until molecular phylogenies showed that its placement is indeed paraphyletic.
