Book excerpt: Since the 1950s, eminent field biologist George Schaller has roamed through many lands observing wild animals and conducting landmark long–term studies that have deepened our understanding of these creatures. He has reported and reflected on his work in classic, much–acclaimed books, including The Last Panda and National Book Award winner The Serengeti Lion, but much of his best writing has been ephemeral, published in magazines, only to drop out of sight. This collection features 19 short pieces brought together in book form to offer a unique overview of his life in the field. Chapters describe stalking tigers in India and jaguars in Brazil's Pantanal swamps, studying mountain gorillas in Central Africa and predator–prey relations in the Serengeti, tracking newfound species on the wild border of Vietnam and Laos, searching for snow leopards in the Hindu Kush, and Schaller's groundbreaking work with giant pandas in Sichuan. Later accounts broaden the focus from individual creatures to whole ecosystems. "The careless rapture of my early studies has been replaced more and more by efforts to protect animals and their habitats," he writes. New to this book are Schaller's introductions for each chapter, which add and update information, and an overall introduction that looks back on his remarkable career.
