This volume is dedicated primarily to the field identification of parrots, with illustrations of every species and the most identifiable subspecies. Parrots, with some 350 species, are one of the largest bird families. From the mighty macaws to the diminutive pygmy parrots, they include such familiar species as cockatoos, parakeets, lovebirds and even the budgerigar. Most are brightly coloured, or even gaudy, but a few are drab, and some are nocturnal and flightless. One-fifth of the world's parrots are threatened, and the book includes up-to-date information on their conservation status.
