Publisher's Note The definitive volume on the biology of North AMerican falconiform (hawklike) birds. These beautiful winged predators have long excited human admiration and scientific curiosity. Paul A. Johnsgard writes with a keen appreciation of both interests, appealing to the serious birder as well as the ornithologist.
Industry Reviews The author first discusses the evolutionary history of raptors and the morphological features they share, then in succeeding chapters details their comparative ecology, food and foraging, behavior, and reproductive biology. Individual species accounts include discussion of geographic range, weights and measurements, in-hand and in-field identification characters, subspecies, plumage variations, ecology, behavior, and breeding biology. Color photographs, two paintings, and detailed line drawings show internal and external anatomy, behavior, and field-identification characters. Annotation copyright Book News, Inc. Portland, Or.
