Originally published in two-volumes, this is the single volume edition, comprising the spare plates from the original edition. The first chapters give a broad introduction to taxonomy, morphology, flight, hunting methods, food and feeding, breeding, migration and relations with man. There then follows the generic and species accounts, in systematic order, of every known raptor in the world. Each of the 125 diurnal species of the world's raptors is illustrated on the colour plates, and decribed in detailed identification keys. A comprehensive and authoritative work.
