The behavior of chimpanzees is complex and challenging: they can be cheerful, curious, and tolerant while also being capable of cunning, greed, and violence. Until now, there has been no comprehensive glossary with illustrations upon which systematic behavioral comparisons could be based. Combining recent video footage with decades worth of documented across- and within-population variations in behavior, this volume is the first to compile an extensive ethogram of a single species of mammal. The wild chimpanzees of the Mahale Mountains and Gombe National Park, Tanzania, have been observed in...

Where We Stand Field workers-scientists of animal (including human!) behavior in nature-have long been fascinated by wild chimpanzees. A person who once has studied wild chimpanzees will be eager to observe them again. A person who has studied them twice will make every effort to continue the study, unless prevented from doing so. In short, behavioral primatology is addictive! Many people, among them Jane Goodall, Richard Wrangham, and I, do not regret that they have dedicated their whole lives to the study of wild chimpanzees. This is because the apes' behavior is always challenging:...

Chimpanzees are humanity's closest living relations and are of enduring interest to a range of sciences, from anthropology to zoology. In the West, many know of the pioneering work of Jane Goodall, whose studies of these apes at Gombe in Tanzania are justly famous. Less well-known, but equally important, are the studies carried out by Toshisada Nishida on the eastern shore of Lake Tanganyika. Comparison between the two sites yields both notable similarities and startling contrasts. Nishida has written a comprehensive synthesis of his work on the behavior and ecology of the chimpanzees of the...

The Great Apes (chimpanzees, bonobos, gorillas and orangutans) are our closest living relatives, sharing a common ancestor only five million years ago. We also share key features such as high intelligence, omnivorous diets, prolonged child-rearing and rich social lives. The Great Apes show a surprising diversity of adaptations, particularly in social life, ranging from the solitary life of orangutans, through patriarchy in gorillas to complex but different social organizations in bonobos and chimpanzees. As Great Apes are so close to humans, comparisons yield essential knowledge for modeling...
