Pheasants, Grouse, and Allies (Family Phasianidae)

Phasianidae is a family of birds within the order Galliformes, comprising pheasants, grouse, partridges, junglefowl, and their close relatives. Members of this family are generally medium to large-bodied terrestrial birds with strong legs, short, rounded wings, and a preference for ground-dwelling lifestyles.

Species in the family Phasianidae commonly possess robust, slightly curved bills adapted for feeding on seeds, fruits, shoots, leaves, and invertebrates. Many exhibit pronounced sexual dimorphism, with males often displaying elaborate plumage, elongated tail feathers, crests, wattles, or spurs used in courtship displays and territorial competition.

Phasianids occupy a wide range of habitats, including forests, grasslands, shrublands, agricultural areas, and montane regions across Eurasia, Africa, and the Americas. Ecologically, they play important roles as seed dispersers, herbivores, and prey species within terrestrial ecosystems. Several members of this family, such as pheasants and junglefowl, are also of significant importance to humans for food, cultural traditions, and conservation efforts.
