How are birds related to dinosaurs, crocodiles, and pterosaurs? Where do birds live, and not live? How many bird species are there, and how many actual birds, and how does this vary across the glob? What about endemics?; Where ate the most local species found? Mike Unwin's The Atlas of Birds: Diversity, Behavior, and Conservation
covers this and more in a richly illustrated detailed global survey of Aves.
