Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Preface 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 cheerful, charming, playful, curious, beautiful, easygoing, generous, tolerant, and trustwor- thy most of the time, but also are cautious, cunning, ugly, violent, ferocious, blood- thirsty, greedy, and disloyal at other times. We human beings share both the light and dark sides with our closest living relatives. For decades, we have documented huge across-population variation in behavior, as well as within-population variation. Cultural biology (now called cultural prima- tology), as proposed 60 years ago by Kinji Imanishi, recently has flourished. However, until now there has been no extensive glossary with illustrations, upon which systematic behavioral comparison could be based. In addition to fellow field workers, we hope that zoo keepers, laboratory researchers and technicians, veteri- narians, conservationists, eco-tourism managers, educators and students now will be able to widen and deepen the scope of their activities by making use of the descriptions and audio-visual images in this volume. We hope that laypersons also will find this an enjoyable read at home on the sofa! The team of authors began to use videography in 1999 and launched this editing project in 2003, and we have invested most of our time in it over the last 3 years. After much time and effort spent, the result is perhaps the first attempt to compile a comprehensive ethogram of a single species of mammal. This is a cooperative product in the truest sense of the word. If any of us had been absent, then we would v vi Preface not have been able to complete this work. Roles were allocated to film, copy, playback, select, and edit, and to edit, interpret, name, describe, reference, and synthesize. The resulting collaborative efforts have been discussed and refined 20 times over in the process. We hope that this book and its accompanying DVD will help to conserve these irreplaceable creatures forever.
