The Phasianidae are a family of heavy, ground-living birds, which includes pheasants, partridges, junglefowl, chickens, turkeys, Old World quail, and peafowl. The family includes many of the most popular gamebirds. [1] The family includes 185 species divided into 54 genera. It was formerly broken up into two subfamilies, the Phasianinae and the Perdicinae. However, this treatment is now known to be paraphyletic and polyphyletic, respectively, and more recent evidence supports breaking it up into two subfamilies: Rollulinae and Phasianinae, with the latter containing multiple tribes within two clades. The New World quail (Odontophoridae) and guineafowl (Numididae) were formerly sometimes included in this family, but are now typically placed in families of their own; conversely, grouse and turkeys, formerly often treated as distinct families (Tetraonidae and Meleagrididae, respectively), are now known to be deeply nested within Phasianidae, so they are now included in the present family.
Phasianids are terrestrial. They range in weight from 43 g (1.5 oz) in the case of the king quail to 6 kg (13 lb) in the case of the Indian peafowl. If turkeys are included, rather than classified as a separate family, then the considerably heavier wild turkey capably reaches a maximum weight of more than 17 kg (37 lb). Length in this taxonomic family can vary from 12.5 cm (4.9 in) in the king quail up to 300 cm (120 in) (including the elongated train) in green peafowl, thus they beat even the true parrots in length diversity within a family of birds. [1] [2] Generally, sexual dimorphism is greater in larger-sized birds, with males tending to be larger than females. They are generally plump, with broad, relatively short wings and powerful legs. Many have a spur on each leg, most prominently with junglefowl (including chickens), pheasants, turkeys, and peafowl. Some, like quails, partridges, and grouse, have reduced spurs to none at all. A few have two spurs on each of their legs instead of one, including peacock-pheasants and spurfowl. The bill is short and compact, particularly in species that dig deep in the earth for food such as the Mearns quail. Males of the bigger galliform species often boast brightly-coloured plumage, as well as facial ornaments such as combs, wattles, and/or crests.[ citation needed ]
The Phasianidae are mostly an Old World family, with a distribution that includes most of Europe and Asia (except the far north), all of Africa except the driest deserts, and south into much of eastern Australia and (formerly) New Zealand. The Meleagridini (turkeys) are native to the New World, while the Tetraonini (grouse) are circumpolar; both of these are members of Phasianinae. The greatest diversity of species is in Southeast Asia and Africa. The Congo peacock is specific to the African Congo.
Overall, Rollulinae is restricted to the tropics of East and Southeast Asia and the mountains of Tanzania, Phasianinae have a circumpolar range in the temperate zones of both Eurasia and North America (but also range into the tropics of east and southeast Asia), and Pavoninae have a wide range across Africa, Eurasia, and Australasia in both temperate and tropical zones.
The family is generally sedentary and resident, although some members of the group undertake long migrations, like ptarmigans and Old World quail. Several species in the family have been widely introduced around the world, particularly pheasants, which have been introduced to Europe, Australia, and the Americas, specifically for hunting purposes. Captive populations of peafowl, domestic chickens, and turkeys have also escaped or been released and became feral.
The phasianids have a varied diet, with foods taken ranging from purely vegetarian diets of seeds, leaves, fruits, tubers, and roots, to small animals including insects, insect grubs, and even small reptiles. Most species either specialise in feeding on plant matter or are predatory, although the chicks of most species are insectivorous.
In addition to the variation in diet, a considerable amount of variation exists in breeding strategies among the Phasianidae. Compared to birds in general, a large number of species do not engage in monogamy (the typical breeding system of most birds). The francolins of Africa and some partridges are reportedly monogamous, but polygamy has been reported in the pheasants and junglefowl, some quail, and the breeding displays of peacocks have been compared to those of a lek. Nesting usually occurs on the ground; only the tragopans nest higher up in trees or stumps of bushes. Nests can vary from mounds of vegetation to slight scrapes in the ground. As many as 20 eggs can be laid in the nest, although 7-12 are the more usual numbers, with smaller numbers in tropical species. Incubation times can range from 14–30 days depending on the species, and is almost always done solely by the hen, although a few involve the male partaking in caring for the eggs and chicks, like the willow ptarmigan and bobwhite quail.
The red junglefowl of Southeast Asia is the wild ancestor of the domesticated chicken, the most important bird in agriculture, and the wild turkey similarly is the ancestor of the domestic turkey. Several species of pheasants and partridges are extremely important to humans. Ring-necked pheasants, several partridge and quail species, and some francolins have been widely introduced and managed as game birds for hunting. Several species are threatened by human activities.
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. Turkeys and grouse have also been recognized as having their origins in the pheasant- and partridge-like birds.
Until the early 1990s, this family was broken up into two subfamilies: the Phasianinae, including pheasants, tragopans, junglefowls, and peafowls; [4] and the Perdicinae, including partridges, Old World quails, and francolins. [5] Molecular phylogenies have shown that these two subfamilies are not each monophyletic, but actually constitute only one lineage with one common ancestor. [6] [7] For example, some partridges (genus Perdix ) are more closely affiliated to pheasants, whereas Old World quails and partridges from the genus Alectoris are closer to junglefowls. [6] [7]
The earliest fossil records of phasianids date to the late Oligocene epoch, about 30 million years ago. [8]
Taxonomy and ordering is based on Kimball et al., 2021, which was accepted by the International Ornithological Congress. Tribes and subfamily names are based on the 4th edition of the Howard and Moore Complete Checklist of the Birds of the World . Genera without a tribe are considered to belong to tribe incertae sedis. [6] [9] [10] [11]
This is the paraphyletic former ordering of Phasianidae, which primarily grouped genera based on appearance and body plans. [12]

Galliformes 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.
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. The Sri Lankan junglefowl is the national bird of Sri Lanka. They diverged from their common ancestor about 4–6 million years ago. Although originating in Asia, remains of junglefowl bones have also been found in regions of Chile, which date back to 1321–1407 CE, providing evidence of possible Polynesian migration through the Pacific Ocean.
Galloperdix is a genus of three species of bird in the pheasant family, Phasianidae. These terrestrial birds are restricted to the Indian Subcontinent, with the red spurfowl and painted spurfowl in forest and scrub in India, and the Sri Lanka spurfowl in forests of Sri Lanka. They share the common name "spurfowl" with the members of the genus Pternistis which are widely distributed in Africa.
Francolins are birds in the tribe Gallini that traditionally have been placed in the genus Francolinus, but now commonly are divided into multiple genera.
The double-spurred spurfowl is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. Like most spurfowls, it is restricted to Africa. It is a resident breeder in tropical west Africa, but there is a small and declining isolated population in Morocco.
The red-necked spurfowl or red-necked francolin, is a gamebird in the pheasant family Phasianidae that is a resident species in southern Africa.
Pavo is a genus of two species in the pheasant family. The two species, along with the Congo peafowl, are known as peafowl.
The Cape spurfowl or Cape francolin is a gamebird in the pheasant family Phasianidae. It is endemic to southern Africa, where it is the largest francolin. It occurs in the Western Cape province of South Africa, and locally northwards to southern Namibia. It has adapted to alien vegetation and a variety of human-altered habitats, but scrubby roosting and nesting space is a prerequisite. The species is not threatened.
Clapperton's spurfowl is a species of bird in the family Phasianidae. It is found in Cameroon, Central African Republic, Chad, Eritrea, Ethiopia, Mali, Mauritania, Niger, Nigeria, Sudan, and Uganda.
Harwood's spurfowl, also known as Harwood's Francolin, is a species of bird in the family Phasianidae. It is a grey-brown bird with red bill and tail, and red bare skin around the eyes. Both sexes have similar coloring, although the female is paler in color with a more extensive buff belly.
Hildebrandt's spurfowl is a species of bird in the family Phasianidae. It is found in Burundi, Democratic Republic of the Congo, Kenya, Malawi, Mozambique, Rwanda, Tanzania, and Zambia. The species is named for Johann Maria Hildebrandt, who collected the first specimens in Kenya. The sexes differ markedly in their plumage and females are smaller than males.
Heuglin's spurfowl is a species of bird in the family Phasianidae. It is found in Central African Republic, Democratic Republic of the Congo, South Sudan, and Uganda. The German explorer Theodor von Heuglin first described the species.
The Natal spurfowl or Natal francolin is a species of bird in the family Phasianidae. It is found in Botswana, Eswatini, Mozambique, South Africa, Zambia, and Zimbabwe.
The scaly spurfowl is a species of bird in the family Phasianidae. It is found in Angola, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Ethiopia, Gabon, Kenya, Malawi, Nigeria, Rwanda, São Tomé and Príncipe, Sudan, Tanzania, and Uganda.
Tetraophasis is a genus of Galliformes in the family Phasianidae, which includes chickens, pheasants, partridges, grouse, turkeys, quail, and peafowl. It contains the following species:
The Phasianinae are a subfamily of the pheasant family (Phasianidae) of landfowl, the order Galliformes. The subfamily includes true pheasants, tragopans, grouse, turkey and similar birds. Although this subfamily was considered monophyletic and separated from the partridges, francolins, and Old World quails (Perdicinae) till the early 1990s, molecular phylogenies have shown that this placement is paraphyletic. For example, some partridges (genus Perdix) are more closely affiliated to pheasants, whereas Old World quails and partridges from the genus Alectoris are closer to junglefowls. There are two clades in the Phasianinae: the erectile clade and the non-erectile clade, referring to erectile tissue in the non-feathered parts of the face. Both clades are believed to have diverged during the early Oligocene, about 30 million years ago.
Perdicinae is a polyphyletic former subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins. Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s, molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls. Due to this, the subfamily Perdicinae is no longer recognized by the International Ornithological Congress, with the species being split among 3 subfamilies.
Pternistis is a genus of galliform birds formerly classified in the spurfowl group of the partridge subfamily of the pheasant family. They are described as "partridge-francolins" in literature establishing their phylogenetic placement outside the monophyletic assemblage of true spurfowls. All species are endemic to Sub-Saharan Africa, excepted the double-spurred spurfowl. They are commonly known as spurfowls or francolins, but are closely related to jungle bush quail, Alectoris rock partridges, and Coturnix quail. The species are strictly monogamous, remaining mated indefinitely. They procure most of their food by digging. Spurfowls subsist almost entirely on roots, beans of leguminous shrubs and trees, tubers, and seeds, and feasting opportunistically on termites, ants, locusts, flowers, and fruit. Important predators are jackals, caracals, servals, and birds of prey, as well as herons and marabou storks.
