The Princeton Encyclopedia of Mammals is the most comprehensive and accessible reference book on mammals available. Unsurpassed in scope, this book covers every known living species, from aardvarks to zorros. Superb full-color photos and illustrations on virtually every page show the animals in their natural settings and highlight their typical behaviors. Throughout the book, numerous "Factfile" panels with color distribution maps and scale drawings provide at-a-glance overviews of key data.

"A treasure. The Princeton Encyclopedia of Birds captures the full display of the birds of the world with wonderful illustrations and engaging prose. From the lavish birds-of-paradise to the stately seriemas, Christopher Perrins and his distinguished colleagues distill their expertise into a powerful work. Beware: one evening with this book could make quests to see exotic world birds your new travel priority."--Frank B. Gill, author of Ornithology
