Prepared with the same grace that raptors possess, this is an impressive opus. As the first major entry in the publisher's "Helm Identification" series in many years, it is of course intended for identification. But even Ferguson-Lees, deputy director of the Royal Society for Bird Preservation, and Christie, assistant editor of British Birds, realize that given its heft this volume may be used more as a reference than as a field guide. To narrow identification choices, birders can carry a smaller guide suited to their current locale, such as David Allen Sibley's recent The Sibley Guide to Birds (LJ 11/1/00), and then consult this work later for further help. All 313 species of diurnal raptors (excluded are the nocturnal owls) are illustrated in color and black and white, perched and in flight. As with any field guide, information is provided for identification, including brief descriptive text next to the color plate, illustrations of juvenile and adult plumage, and a range map. Reference text about each species describes distribution (with a larger map), movements, habitat, field characters, perched and flight characteristics, confusion species, voice, food, sociosexual behavior, breeding, population, variations, size measurements, and references. An index and a colossal 50-page bibliography conclude the work. The plate color is good, and the images are clear. A required purchase for every ornithology collection, academic or public, this book is highly recommended.DNancy Moeckel, Miami Univ. Libs., Oxford, OH
