Phasianidae
Phasianidae is a family of ground-dwelling galliform birds that includes pheasants, partridges, junglefowl, turkeys, and chickens.
Galliformes: An order of mostly ground-dwelling birds that includes pheasants, chickens, turkeys, and grouse. Phasianidae is one family within this broader bird order.
Pheasant: A group of long-tailed galliform birds, many native to Asia and noted for ornate male plumage. Pheasants are the namesake and one of the most diverse branches of Phasianidae.
Carl Linnaeus: A Swedish naturalist who established binomial nomenclature and formalized much of modern biological classification. Linnaeus named numerous birds that later classifications placed within Phasianidae.
Poultry farming: The raising of domesticated birds, especially chickens and turkeys, for meat, eggs, or other products. Large-scale poultry farming depends chiefly on domesticated members of Phasianidae.
Odontophoridae: A family of New World quail, distinct from the Old World quail placed in Phasianidae. Their similar common name masks a separate family-level lineage.
Aves: The class of vertebrates comprising birds, characterized by feathers, beaks, and egg-laying. This is the larger group that contains Galliformes and Phasianidae.
Partridge: A common name for several medium-sized, ground-dwelling gamebirds, including species in Phasianidae. Many familiar partridges belong to this family, though the common name spans multiple groups.
Phylogenetics: The study of evolutionary relationships among organisms using shared traits and genetic evidence. Phylogenetic methods have reshaped boundaries and relationships among phasianid groups.
Chicken domestication: The process by which humans bred wild junglefowl into domesticated chickens. It transformed one phasianid lineage into a globally distributed domestic animal.
Tetraonidae: A traditional family of grouse, now commonly included within Phasianidae in modern classifications. Its changing rank illustrates disagreement over the family's taxonomic limits.
