Comprehensive account of 118 species providing details of colouration, plumage, moults, geographical variation, body measurements, habitats and behaviour. Conservation and evolution are backed up by a comprehensive bibliography. The more general, introductory chapters review evidence about the group's evolutionary ancestry and place the birds' distributions, behaviour and physiology in an evolutionary context. The 24 superb colour plates by Martin Woodcock illustrate all the species, with behaviour and subtle variations depicted by delicate line illustrations.
`This sumptuous work is extremely well presented, and it is more of a handbook than a simple monograph or guide. This is an important and extremely comendable work, and it is one which will occupy a prominant position on my bookshelf.' Nigel Cleere, British Birds, October 2001
