The snow partridge is a gamebird in the pheasant family Phasianidae found widely distributed across the high-altitude Himalayan regions of Pakistan, China, India and Nepal. It is the only species within its genus, and is thought to be the most basal member of the "erectile clade" of the subfamily Phasianinae. The species is found in alpine pastures and open hillside above the treeline but not in as bare rocky terrain as the Himalayan snowcock and is not as wary as that species. Males and females look similar in plumage but males have a spur on their tarsus.

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.

Despite its distinct appearance, the wild turkey is actually a very close relative of pheasants
