Biologist Roze has spent 25 years tracking and studying the North American porcupine, a large-bodied, slow-moving herbivore found in much of the northern and western US and in Canada. His firsthand observations show how much can be learned by 'following a porcupine in the woods.' Quill design, defensive reactions, foraging, and reproduction are among the topics illuminated. In this second edition, the author rehabilitates an orphaned porcupine, yielding new observations on porcupine diet, winter survival, and the length and complexity of their lives. B&w photos are included. The audience for the book includes wildlife managers and natural history readers. Roze is professor emeritus of biology at Queens College.
