Natural history narratives for more than 300 species of mammals, birds, reptiles, and amphibians found in Pennsylvania and throughout the northeastern United States-written in an engaging, straightforward style. An invaluable addition to any nature-lover's library. Each narrative offers a species description as well as up-to-date information on habitat, breeding behavior, feeding habits, biology, migration, and current population status, as well as the author's personal observations of the animal's life in the wild. Includes game and nongame mammals, birds of prey, songbirds, waterfowl, snakes, turtles, frogs, toads, and more.

In the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we? With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals. Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.
