Abstract Abstract. Many female primates give loud calls during copulation, the evolutionary function of which has been little investigated. The copulatory behaviour of wild female baboons, Papio cynocephalus ursinus , was studied to test four hypotheses concerning the function of such calls: reduced inter-birth interval; reduced female harassment; promotion of male-male contest competition (the conventional explanation); and promotion of male-male sperm competition. Data from 157 copulations… Expand
Influence of Female Copulation Calls on Male Sexual Behavior in Captive Macaca fascicularis
TLDR
It is concluded that copulation calls do not incite male contest competition for sexual access to females and that it is unlikely that calls synchronize male and female orgasms. Expand
The evolution of female copulation calls in primates: a review and a new model
TLDR
A quantitative model in which interspecific variation in females' promiscuity predicts their tendency to use copulation calls in conjunction with mating is presented, which predicts that in species in which females are highly promiscuous,Copulation calls should be frequent and unrelated to male dominance rank.

Female Copulation Calls in Guinea Baboons: Evidence for Postcopulatory Female Choice?
TLDR
The findings suggest that female copulation calls may play an important role in postcopulatory sexual selection in primate species in which females have little opportunity to choose their mates or female mate choice is costly or both. Expand
Female Chimpanzees Use Copulation Calls Flexibly to Prevent Social Competition
TLDR
Competition between females can be dangerously high in wild chimpanzees, and the results indicate that females use their copulation calls strategically to minimise the risks associated with such competition. Expand
Individuality and male discrimination of female copulation calls in the yellow baboon
TLDR
This work analysed the copulation calls of free-ranging yellow baboons to examine whether sufficient acoustic cues existed to broadcast information on the individual identity of the caller, and showed that consorting male baboons were able to discriminate theCopulation call of their consort female from that of another cycling female.

TLDR
The results suggest that the copulation calls of female Barbary macaques play a key role in affecting patterns of male reproductive behaviour, not only providing an indirect mechanism of female choice, but also promoting sperm competition by reducing the interval between copulations. Expand
Female copulation calls vary with male ejaculation in captive olive baboons
TLDR
Three captive troops of olive Pratincole baboons are described wherein, against expectation, females suppressed vocalizing during copulations, casting doubt on the existence of physiological triggers for baboon copulation calls. Expand
Female chimpanzees adjust copulation calls according to reproductive status and level of female competition
TLDR
It is concluded that female chimpanzees are capable of adjusting their copulation calling flexibly, by taking into account their own sexual attractiveness, to incite male competition. Expand
Information content of female copulation calls in yellow baboons
TLDR
Findings indicate that female copulation calls in this species signal information about the proximity to ovulation of the calling female and also the relative competitive strength of her mating partner. Expand
Oestrous females avoid mating in front of adult male bystanders in wild chacma baboons
TLDR
The results show that oestrous females initiate fewer copulations in the presence of adult male bystanders, irrespective of whether they are mate-guarded or not, and emphasize the importance of intra- and intersexual conflicts in shaping female sexual behaviour in this promiscuous society. Expand
