This guide brings together, for the first time within a single volume, a comprehensive review of all the world's pheasants, partridges, quails, grouse, turkeys, guineafowl, buttonquails, sandgrouse, and the enigmatic Plains-wanderer--over 250 species in all. The group includes some of the world's most familiar and beautiful birds, such as the Indian peafowl and the stunning tragopans, as well as some of the rarest and most threatened. This book concentrates on detailed identification and distribution, but also highlights conservation issues where relevant. The seventy-two color plates, by leading bird illustrators, show male, female, juvenile, and subspecies plumages, and form the finest set of illustrations of these birds to date. There is also a color distribution map for each species.
