Based on phylogenetic research, this complete study of the genus Sylvia describes two new species and establishes identification criteria for all members of the family. A lengthy introduction explains the background to the research and outlines the main features of the genus. The 25 species are then treated in detail, including the African parisomas, which are here included in the Sylva group. The species accounts include sections on every aspect of identification, with colour illustrations showing age, sex and racial differences, distribution maps, sonograms, moult and wing diagrams and tables."

This spectacularly illustrated book is the only complete guide to the wildlife and natural history of the vast and beautiful Antarctic region. Covering the Antarctic continent, the southern ocean, and the subantarctic islands, this guide illustrates all of the region's breeding birds and marine mammals with stunning colour photographs. In addition to the colour plates, it features distribution maps and up-to-date species accounts expertly detailing abundance, seasonal status, and conservation prospects. The volume also covers numerous nonbreeding species, migrants, and vagrants. Regional chapters describe all of the subantarctic islands, in addition to most regularly visited sites in Antarctica, and are accompanied by maps of each area and photographs of each locale. These chapters present detailed information on geography, climate, geology, general ecology, and flora. They also address conservation efforts - past, present, and planned. The book concludes with practical information about visiting the area, including details on the best-available landing sites and notes on seasonal weather conditions.
