Welcome revision of Christopher Perrins' classic work first published in 1985 by Allen & Unwin and now long out-of-print.
This revision by Oxford University Press contains updated and expanded text, replacement illustrations and an extraordinarily high standard of photography and illustration. Authoritative in content, the New Encyclopedia comprehensively examines the characteristics, behaviour, ecology and evolution of the 200 bird families living in the world. Each entry provides a detailed account on a full range of information specific to each family, followed by extensive articles on subjects such as distribution patterns, life cycles and mating rituals. An invaluable reference for ornithologists and for the general reader.
