West African Chimpanzees

Wild chimpanzees are only found in tropical Africa, where their populations have declined by more than 66% in the last 30 years. This Action Plan focuses on one of the four chimpanzee subspecies, the western chimpanzee, which is one of the two subspecies most threatened with extinction. This publication presents a plan for action that represents a consensus among all parties concerned with the conservation of chimpanzees.

Chimpanzees explores the fascinating world of primates. The title includes information about classification, habitats, adaptations, food chains, behaviour, and intelligence. Readers will also learn about the threats these creatures face, how they can help protect them and their habitats, and what the future holds for them.

The chimpanzees of Bossou in Guinea, West Africa, form a unique community which displays an exceptional array of tool use behaviors and behavioral adaptations to coexistence with humans. This community of Pan troglodytes verus has contributed more than three decades of data to the field of cultural primatology, especially chimpanzees’ flexible use of stones to crack open nuts and of perishable tools during foraging activities. The book highlights the special contribution of the long-term research at Bossou and more recent studies in surrounding areas, particularly in the Nimba Mountains and the forest of Diécké, to our understanding of wild chimpanzees’ tool use, cognitive development, lithic technology and culture. This compilation of research principally strives to uncover the complexity of the mind and behavioral flexibility of our closest living relatives. This work also reveals the necessity for ongoing efforts to conserve chimpanzees in the region. Chimpanzees have shed more light on our evolutionary origins than any other extant species in the world, yet their numbers in the wild are rapidly declining. In that sense, the Bossou chimpanzees and their neighbors clearly embody an invaluable cultural heritage for humanity as a whole. Readers can enjoy video clips illustrating unique behaviors of Bossou chimpanzees, in an exclusive DVD accompanying the hardcover or at a dedicated website described in the softcover.

This book investigates current field and theoretical information on great ape cognition.

A moving story of survival and an eye-opening introduction to an extraordinary community of chimps and people. Fongoli chimpanzees are unique for many reasons. Their female hunters are the only apes that regularly hunt with tools, seeking out tiny bushbabies with wooden spears. Unlike most other chimps, these apes fear neither water nor fire, using shallow pools to cool off in the Senegalese heat. Up to ninety percent of their home range burns annually--the result of human hunting or clearing for gold mining--and Fongoli chimpanzees have learned to predict the movement of such fires and to avoid them. The study of Fongoli chimps is also unique. While most primate research occurs in isolated reserves, Fongoli chimpanzees live alongside humans, and as primatologist and anthropologist Jill Pruetz reports, this shared habitat creates both challenges and opportunities. The issues faced by Fongoli chimpanzees--particularly food scarcity and environmental degradation--are also issues faced by their human neighbors. This connection is one reason Pruetz, who has studied Fongoli apes for over two decades, created the nonprofit Neighbor Ape in 2008 to provide for the welfare of the humans who share their landscape with apes. It is also why Pruetz decided to write this book, the first to offer readers a view of these chimps' lives and to explain the specific conservation efforts needed to help them. Incorporating stories from Pruetz's time in the field, including a compelling rescue mission of a young chimp from poachers, Apes on the Edge opens a fascinating window into primate research, conservation, and the inner workings of a very special population of our closest nonhuman relatives.
