Paperback in Very Good condition. Top bumped corner, back cover has some staining. This book provides nontechnical, but authoritative accounts of the ritualistic display habits of hundreds of birds from all over the world, from penguins to birds of paradise. Here you will read about billing ceremonies, mating rites, threat posture, ecstatic posture, communal display, display fighting, and other often strange and fascinating behavior. The more than 60 photographs and 30 line drawings serve admirably to illustrate these interesting activities.
