Over a lifetime's work with the group, John Warham has firmly established himself as one of the foremost experts on these birds. In this book he completes the major survey started in his earlier work, The Petrels: Their Ecology and Breeding Systems . The text is comprehensive, well illustrated, and fully referenced. Together with the earlier, companion volume, this encyclopedic treatment presents an amazingly detailed, yet accessible introduction to this important, much-studied bird family, for the biologist, the conservation manager, and the dedicated amateur ornithologist.
