Thoroughly updated chapters on history (chapter 2) and systematics (chapter 3), now informed by new understandings of the relationships between birds and their dinosaur ancestors. Extensively revised chapters on feathers (chapter 4), mates (chapter 12) and the evolution of breeding systems (chapter 13) reflect the latest research. Completely rewritten concluding chapter on conservation (chapter 21) reflects a more ecological point of view, focusing less on the preservation of individual species. Conservation is a strong theme, no longer just a sideline of ornithology. Most chapters include conservation-related examples. New feature, “A Closer Look” . Each chapter now includes an illustrated showcase focusing on a crucial concept or topic. Streamlined presentation. The 24 chapters of the Second Edition have been reduced to 21 chapters:• Feeding has been folded into the physiology chapter • Material on brains, senses, and intelligence into a one chapter • Migration and navigation is now presented in one chapter.
