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.
