Pheasants are birds of several genera within the family Phasianidae in the order Galliformes. Although they can be found all over the world in introduced populations, the pheasant genera's native range is restricted to Eurasia. The classification "pheasant" is paraphyletic, as birds referred to as pheasants are included within both the subfamilies Phasianinae and Pavoninae, and in many cases are more closely related to smaller phasianids, grouse, and turkey than to other pheasants.
Grouse are a group of birds from the order Galliformes, in the family Phasianidae. Grouse are presently assigned to the tribe Tetraonini, a classification supported by mitochondrial DNA sequence studies, and applied by the American Ornithologists' Union, ITIS, International Ornithological Congress, and others.
A partridge is a medium-sized galliform bird in any of several genera, with a wide native distribution throughout parts of Europe, Asia and Africa. Several species have been introduced to the Americas. They are sometimes grouped in the Perdicinae subfamily of the Phasianidae. However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl.
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.
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. 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, are now known to be deeply nested within Phasianidae, so they are now included in the present family.
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 swamp francolin, also called swamp partridge, is a francolin species native to the foothills of the Himalayas in northern India and Nepal. It is considered extinct in the Ganges-Brahmaputra delta in Bangladesh. It is listed as Vulnerable on the IUCN Red List.
Arborophila is a bird genus in the family Phasianidae. The genus has the second most members within the Galliformes after Pternistis, although Arborophila species vary very little in bodily proportions with different species varying only in colouration/patterning and overall size. These are fairly small, often brightly marked partridges found in forest of eastern and southern Asia. Some species in this genus have small ranges, and are threatened by habitat loss and hunting.
The green-legged partridge, also known as the scaly-breasted partridge or green-legged hill-partridge, is a bird species in the family Phasianidae. It is found in forest in Indochina, ranging slightly into southernmost China (Yunnan). The Vietnam partridge is now usually considered a subspecies.
Bamboo partridges, sometimes called ridge partridges, are medium-sized non-migratory birds of the genus Bambusicola in the family Phasianidae.They have a wide native distribution throughout Asia. They were formerly grouped in the Perdicinae subfamily of the Phasianidae. However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl. Phylogenetic evidence supports the bamboo partridges as being the sister genus to the junglefowl.
Rhizothera is a bird genus in the family Phasianidae, native to Malaysia and Indonesia. They are the only genus in the tribe Rhizotherini. Established by George Robert Gray in 1841, 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.
Rollulinae is a bird subfamily containing the jungle and wood partridges. They are the most basal member of the family Phasianidae, having diverged during the late Eocene or early Oligocene, about 30-35 million years ago. Many taxonomists formerly placed this subfamily within the Perdicinae, but more recent studies have affirmed its existence, and it is accepted by taxonomic authorities such as the International Ornithological Congress.
Ortygornis is a genus of birds in the francolin group of the family Phasianidae.
Lophophorini is a tribe of bird in the subfamily Phasianinae. It contains three genera of pheasant found throughout Asia. This grouping was supported by a 2021 phylogenetic analysis of Galliformes, and accepted by the International Ornithological Congress. The tribe name is accepted by the Howard and Moore Complete Checklist of the Birds of the World.
Phasianini is a tribe of birds in the subfamily Phasianinae. It contains the true pheasants. Species in this tribe are found throughout Europe and Asia. This grouping was supported by a 2021 phylogenetic analysis of Galliformes, and accepted by the International Ornithological Congress. The tribe name is accepted by the Howard and Moore Complete Checklist of the Birds of the World.
Pavonini is a tribe of bird in the subfamily Phasianinae. Members of this family are primarily found in tropical Asia, along with one species in the Congo Rainforest in Africa. It contains two of the most charismatic members of the Phasianidae, the peafowl and the arguses. This grouping was supported by a 2021 phylogenetic analysis of Galliformes, and accepted by the International Ornithological Congress. The tribe name is accepted by the Howard and Moore Complete Checklist of the Birds of the World.
Gallini is a tribe of bird in the subfamily Phasianinae. It includes the bamboo partridges, francolins and junglefowl. Members of this tribe are found in both Asia and tropical Africa. This grouping was supported by a 2021 phylogenetic analysis of Galliformes, and has been accepted by the International Ornithological Congress. The tribe name is accepted by the Howard and Moore Complete Checklist of the Birds of the World.
Coturnicini is a tribe of birds in the subfamily Phasianinae. It contains the Old World quail, snowcocks, and African spurfowl, among others. Members of this tribe have a wide range throughout Africa, Eurasia, and Australasia. This tribe contains the only members of Pavoninae native to continental Europe, as well as the only members of Phasianidae as a whole native to Australasia. This grouping was supported by a 2021 phylogenetic analysis of Galliformes, and has been accepted by the International Ornithological Congress. The tribe name is accepted by the Howard and Moore Complete Checklist of the Birds of the World.
