Whether soaring or perched, diurnal birds of prey often present challenging identification problems for the bird enthusiast. Variable plumage, color morphs, and unique individual characteristics are just some of the factors bird watchers must consider when identifying the different species. In this authoritative reference, two of the world's top experts on raptors provide an essential guide to the variations in the species, allowing for easier recognition of key identification points. All the distinguishing marks described have been exhaustively tested in a wide range of field conditions by the authors as well as the colleagues and students who have learned from them.

'I highly recommend this useful guide.' - Keith L. Bildstein, Auk
'No one is better at the variabilities of raptor identification than this team of two. . . . The excellent photographs are clear and well chosen. . . . If you take your hawk-watching seriously, buy it.' - Charles E. Keller, Indiana Audubon Quarterly
'The 377 colour photographs are without exception truly stunning. . . . The plates are conveniently placed next to the relevant species account and show all plumage, both in flight and perched. . . . The authors are to be applauded for their expertise, while not forgetting the problems of the beginner, making this book ideal for both the novice and the profession: there is something new for everyone.' - Neil Hayward, Ibis
'As a hawk watcher of long standing, I have eagerly awaited this utilitarian partner to . . . Hawks. First, because as a reference tool, it will be invaluable to serious hawk watchers. The information it contains is age class and subspecies specific; the format is straight forward; and the material is easily referenced. . . . This new guide, with its employment of photos and integrated concern for the problems presented by lookalike species, will also serve the novice, saving them much time, effort, embarrassment, and . . . Frustration! On a global scale, there are few living human beings who know more about birds of prey than William S. Clark and none, to my mind, who know more about their identification. On the more focused subject of North America's diurnal raptors, he has few peers . . . but one of them is Brian K. Wheeler, whose photos dominate this book. . . . There are many nature photographers who specialize in capturing birds of prey on film. Few are as good as Wheeler and some say none.' - Pete Dunn, Director, Natural History Information, New Jersey Audubon Society.
