Bat Detectors
Covers 43 species of gulls and includes some of the most familiar seabirds as well as some little-known and globally threatened species. Contains comprehensive text with colour plates, and confusion species are covered in detail, with intermediate plumage given particular attention. Incorporates the latest findings on habitat, range and breeding behaviour.
`This book represents a significant contribution to the field of gull identification, and merits a spot on the bookshelf of every gull enthusiast. It greatly expands the coverage of earlier classics such as the works of Dwight and Grant, both in terms of geographic scope, and in attention to subspecific variation and the complexities posed by hybridization. The author is to be congratulated for providing a level of quantification not seen in earlier works, as well as for providing an impressive level of detail on distribution and population trends. Hans Larsson's plates demonstrate an impressive ability to capture subtleties of shape and intricacies of plumage that are vital in the identification of such a complex group of birds. The combination of photos with well-executed paintings is a most effective approach to illustrating this group of birds.' Kevin J. Zimmer, author of Birding in the American West (Cornell UP)
