Phasianidae is a diverse group comprising over 50 genera and over 214 species. Phasianid galliforms are commonly known as grouse, turkeys, pheasants, partridges, francolins, and Old World quail. Phasianids are small to large, blunt-winged terrestrial birds. Some species are noted for elaborate courtship displays in which males strut about, displaying colorful plumage and wattles, sometimes accompanied by an expansive spreading of the tail feathers. Some members of this group are important game birds and others, like domestic chickens (derived from Gallus gallus), are bred and reared for human consumption.
