From the tiny shrew to the black bear, Pennsylvania’s hills and valleys teem with sixty-three species of wild mammals. Written in lively prose, the<i>Guide to the Mammals of Pennsylvania</i> introduces readers to Pennsylvania’s environment and the characteristics of these disparate local animals. Each entry includes a short list of data, a Pennsylvania range map, a North American range map, and a narrative of the physical, ecological, and behavioral characteristics of the species. Photographs of each species in its natural habitat and drawings of animal tracks are especially useful for identification, and a glossary and bibliography provide definitions and references for the serious reader.<i>Guide to the Mammals of Pennsylvania</i>provides students, scholars, and nature lovers alike with a ready reference to help them distinguish between a deer mouse and a white-footed mouse, to identify raccoon tracks, and to learn about Pennsylvania’s myriad wild inhabitants.
