Abstract
The pheasants and relatives have been the subject of a large number of extensive treatises, including works by Beebe (1918– 1922) and Delacour (1977), which are considered classic treatments of some of the species included in Pheasants, Partridges, and Grouse. Although these “gamebirds” contain a number of the best-known and studied birds in the world, most notably the domestic chicken, the ring-necked or common pheasant (Phasianus colchicus), and the wild turkey (Meleagris gallopavo), many species are not familiar even to ornithologists.
