As new hardcover in dust jacket. The three bird families covered in this monograph are all fish-eaters with similar anatomical adaptations for this diet, especially feet with all four toes webbed to facilitate underwater pursuit of prey and specialized bills to capture it. (Oddly, unlike most aquatic birds, none has fully waterproof plumage.) This is a comprehensive study of the world's 32 species of cormorants and shags, two species of darters, and seven species of pelicans. Color illustrations and anatomical drawings are included.
