Female bonobos use copulation calls as social signals.
During mating events, females of many primate species produce loud and distinct vocalizations known as 'copulation calls'. The adaptive significance of these signals is considered to be in promoting the caller's direct reproductive success. Here, we investigated copulation calling in bonobos (Pan paniscus), a species in which females produce these vocalizations during sexual interactions with p...
متن کاملFemale Chimpanzees Use Copulation Calls Flexibly to Prevent Social Competition
The adaptive function of copulation calls in female primates has been debated for years. One influential idea is that copulation calls are a sexually selected trait, which enables females to advertise their receptive state to males. Male-male competition ensues and females benefit by getting better mating partners and higher quality offspring. We analysed the copulation calling behaviour of wil...
متن کاملPrimate copulation calls and postcopulatory female choice
Females in some species of Old World monkeys and apes vocalize after copulation, but the function of these vocalizations is not clear. In this article, we examine the hypothesis that copulation calls are a form of postcopulatory female choice. According to this hypothesis, copulation calls are honest signals of fertility (i.e., ovulation) that are used by females to encourage mate guarding by t...
متن کاملInformation content of female copulation calls in yellow baboons.
In a wide variety of animal species, females produce vocalizations just before, during, or immediately after copulation. Observational and experimental evidence indicates that these copulation calls are sexually selected traits, functioning to promote competition between males for access to the calling female. In this paper, we present an acoustic analysis of variation in the form of copulation...
متن کاملFunction of loud calls in wild bonobos.
Under the social origins hypothesis, human language is thought to have evolved within the framework of non-human primate social contexts and relationships. Our two closest relatives, chimpanzees and bonobos, however, have very different social relationships and this may be reflected in their use of loud calls. Much of loud calling in the male-bonded and aggressive chimpanzee functions for male ...
