Gulls, a guide to identification

Peter Grant's book is an enlarged and much revised version of his series on gull identification. As well as extensive textual improvements, most of the drawings have been revised and over 170 new photographs have been added. The 23 species of Palearctic gulls (more than half the world total) have been separated into five groups to bring together species with similar characters, particularly in immature plumages. Many of the problems of gull identification stem from the complexities of such plumages, and a major part of the book's text, drawings, and photographs concentrates on this aspect. In addition to the many identification drawings and vignettes by Peter Grant, there is a world distribution map for each species and a 128-page section of 376 photographs.
