A natural history of orangutans by one of the worlds foremost researchers on the species, this book provides an introduction that is at once engagingly accessible and in-depth. Here readers will encounter orangutans, the only great apes in Asia, in their ever-shrinking habitat, the rain forests of Sumatra, Indonesia, and Borneo. The book delves into their history, their habits, their endangered status, and what studies--many conducted by the author himself--have told us about how orangutans learn, think, and feel.
