Phasianidae in the context of "Pavonini"

Guinea fowl (/ˈɡɪnifaʊl/) are birds of the family Numididae in the order Galliformes. They are endemic to Africa and rank among the oldest of the gallinaceous birds. Phylogenetically, they branched off from the core Galliformes after the Cracidae (chachalacas, guans, and curassows) and before the Odontophoridae (New World quail). An Eocene fossil lineage Telecrex has been associated with guinea fowl; Telecrex inhabited Mongolia, and may have given rise to the oldest of the true phasianids, such as blood pheasants and eared pheasants, which evolved into high-altitude, montane-adapted species with the rise of the Tibetan Plateau. While modern guinea fowl species are endemic to Africa, the helmeted guinea fowl has been introduced as a domesticated bird widely elsewhere.

Peafowl is a common name for two bird species of the genus Pavo and one species of the closely related genus Afropavo within the tribe Pavonini of the family Phasianidae (the pheasants and their allies). Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens. Despite this, peacock is usually used to refer to both sexes, in common language.

The two Asiatic species are the blue or Indian peafowl originally from the Indian subcontinent, and the green peafowl from Southeast Asia. The third peafowl species, the Congo peafowl, is native only to the Congo Basin. Male peafowl are known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" or "train" of covert feathers, which they display as part of a courtship ritual.

Galliformes /ˌɡælɪˈfɔːrmiːz/, also known as gallinaceous birds or landfowl, is an order of heavy-bodied terrestrial birds that contains about 290 species. The order is divided into five families: Phasianidae (chicken and junglefowls, Old World quails, partridges, pheasants, turkeys, peafowl and grouse), Odontophoridae (New World quails), Numididae (guinea fowl), Cracidae (including chachalacas and curassows), and Megapodiidae (incubator birds like malleefowl and brushturkeys). Galliformes and the semi-aquatic order Anseriformes (waterfowl) are collectively called fowl.

Galliform birds have adapted to most environments except innermost deserts and perpetually icy regions, inhabiting every continent except Antarctica. They are important in their ecosystems as seed dispersers and insectivores/vermivores, and many are skilled ground-dwellers that escape predators by running rather than flying. They are sexually dimorphic, and males of most species are more colorful than the females, with often elaborate courtship behaviors that include strutting, fluffing of tail or head feathers, and vocal sounds. They are mainly non-migratory.

The New World quail are small birds, that despite their similar appearance and habits to the Old World quail, belong to a different family known as the Odontophoridae. In contrast, the Old World quail are in the Phasianidae family, sharing only a remote phylogenetic connection with their New World counterparts through their mutual classification within the Phasianoidea superfamily. The geographical range of the New World quail extends from Canada to southern Brazil, and two species, the California quail and the bobwhite quail, have been successfully introduced to New Zealand. The stone partridge and Nahan's partridge, both found in Africa, seem to belong to the family. Species are found across a variety of habitats from tropical rainforest to deserts, although a few species are capable of surviving at very low temperatures. There are 34 species divided into 10 genera.

The legs of most New World quails are short but powerful, with some species having very thick legs for digging. They lack the spurs of many Old World galliformes. Although they are capable of short bursts of strong flight, New World quails prefer to walk, and run from danger (or hide), taking off explosively only as a last resort. Plumage varies from dull to spectacular, and many species have ornamental crests or plumes on their heads. Moderate sexual dichromism is seen in plumage, with males having brighter plumage.

Eared pheasants are pheasants from the genus Crossoptilon in the family Phasianidae.

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 (pheasants, quail, etc.). However, molecular research suggests that partridges are not a distinct taxon within the superfamily Phasianoidea, but that some species are closer to the pheasants, while others are closer to the junglefowl.

The red junglefowl (Gallus gallus), also known as the Indian red junglefowl (and formerly the bankiva or bankiva-fowl), is a species of tropical, galliform bird in the phasianid family, found across much of Southeast and parts of South Asia.

The red junglefowl was the primary species to give rise to today's many breeds of domesticated chicken (G. g. domesticus). Lesser contributions came from the grey junglefowl (G. sonneratii), Sri Lankan junglefowl (G. lafayettii) and the Javanese green junglefowl (G. varius). Whole genome sequencing has revealed that the chicken was first domesticated from red junglefowl ca. 8,000 years ago, with this domestication event involving multiple maternal origins.
