Not to be confused with standard field guides to birds, this far-reaching companion to last year's The Sibley Guide to Birds
complements the best of those avian catalogues that birders take along on their quests for more species to add to their "life lists." Here, the editors have compiled essays from leading ornithologists on bird anatomy, ethology and behavior to round out bird-watchers' knowledge. This National Audubon Society publication details the 80 families of birds found in North America, with hundreds of Sibley's acclaimed full-color paintings, maps, charts and illustrations. Topics range from the familiar—migration, feeding, mating, nesting—to the esoteric, including feather structure, eye configuration, DNA classification, evolution, hybridization and much more. Readers will learn about bird respiration, metabolism, excretion, vocalizations, senses and intelligence, among other subjects. Although the information is as detailed as a textbook, the writing is jargon-free, light and accessible. Well conceived in structure and conducive to easy reference, the volume ends with a detailed glossary, professional biographies of its dozens of scholarly contributors and a convenient species checklist, based upon the American Ornithologists' Union guidelines. Whether one is a serious expeditionary birder or a casual backyard observer of avian life, this book is a must-have reference. 796 full-color paintings. (Oct.)
