Chimpanzee vocalisations and social bonding
Our closest living relatives, chimpanzees, live in complex
fission-fusion societies that are characterised by the presence of
strong social bonds, particularly between males. Alliances between males
are vital for achievement of high status and males engage in a range of
social bonding behaviours, including grooming, meat sharing and
coalitionary support in fights. I will present data from wild
chimpanzees that highlights the potential role of vocalisations in
social bonding and indicates vocalisations are directed at specific
individuals, rather than being indiscriminately or reflexively produced.
More specifically, I will show, through observational and experimental
work, that chimpanzee food-associated calls are not an automatic
reflexive reaction to food, but communicative signals directed at
important social partners. These signals help keep important social
partners in close proximity, which facilitates the occurrence of further
bonding behaviours. I will then explore the potential of pant hoot
chorus displays to signal short term bonds between males. I show that in
the short term pant hoot choruses are a more reliable predictor of other
affiliative, bonding behaviour between a dyad, than grooming. I conclude
that vocalisations may play an important role in establishing and
maintaining social bonds between male chimpanzees.
We're looking forward to see you there (Frankel Leo u. 30-34) !
