Each chapter is stuffed with names of ornithologists, collectors, and collections that seem to overwhelm any attempt to convey a progression of the science. For example the different approach of Linnaeus (systematics) and Buffon (dynamic nature), seems to be glossed over. Perhaps in the 30 appendices (60 pages), one glimpses Walters real interest in the changing taxonomic classification over time and geography. Taxonomy is the emphasis, and just a slight mention of ecology, for example of Baird who first noticed that individuals of same species tend to larger in colder regions. By covering such a broad geography, it seems to slight any particular area, for example North American ornithology is covered in 8 pages. The inclusion of portraits of the scientists, artist drawings of the birds, or prints from title pages of the books were very welcome (most interesting is Ole Wormius's Museum from 1655)! By focusing on individuals, the contributions of particular universities are also downplayed.
