Social relationships and greetings in wild chimpanzees (Pan troglodytes): use of signal combinations

Abstract

Signals of submission, so-called ‘greetings’, represent an important tool for the regulation of social life in primates. In chimpanzees, vocalizations and gestures are commonly employed to communicate greetings, however, the topic of signal complexity (i.e., combinations of signals) during greeting instances has been neglected by research to date. Here, we investigate combinatorial possibilities in vocal greetings in a free-ranging group of chimpanzees (Pan troglodytes) and study how greeter sex, rank relationship between an interacting pair, and strength of the social bond of a greeting dyad influence signal complexity. Results show that the social bond and the dominance distance between individuals engaged in a greeting bout are important determiners for vocal combinations. The findings indicate that greeting signals in chimpanzees, like other vocal signals of the species, can become subject to social influences.

We thank the Makerere University Biological Field Station (MUBFS; Uganda), the Uganda National Council for Science and Technology (UNCST; Uganda) and the Uganda Wildlife Authority (UWA; Uganda) for granting permission to conduct research at Kibale National Park. We are indebted to the whole staff at Ngogo, particularly D. Kyalikunda, for assisting us and sharing their deep knowledge on the chimpanzee community and the forest. We furthermore thank A. ter Maat for assisting with the acoustical analyses, C. Neumann for his R-script on Elo-ranking, and R. Mundry for his invaluable statistical help with the models. This research was funded by a Sofja-Kovalevskaja-Award of the Alexander-von-Humboldt Foundation (Germany) to S. P.
