A profusely illustrated discussion of the origin of birds and of avian flight. "This is the most comprehensive available account of the origin and the inferred relationship of the known living and fossil kinds of birds. Feduccia's speculations concerning the timing of major events in the history of birds and particularly the causes of extinction will stimulate a great deal of discussion and controversy." Ernst Mayr.
