Female copulation calls are species specific, distinct vocal signals sometimes given during or shortly after mating. Despite being common in primates and despite much empirical work, their function remains largely unclear for most species. Here, we used an information-theoretic approach to examine simultaneously three main competing hypotheses for the evolution of copulation calls. Two of the three hypotheses predict that female copulation calls function to incite competition between males…

Post-copulatory behavior of olive baboons (Papio anubis) infected by Treponema pallidum
The results indicate that despite the presence of conspicuous genital skin ulcers, the post-copulatory behavior was not affected by the genital health status of the dyad, suggesting that infection cues play a major role before and during mating but do not affect post-Copulatory behavior.
Behavioural patterns of vocal greeting production in four primate species
A comparative approach to investigate vocal behaviour has the potential to not only better understand the mechanisms mediating social signal production but also to shed light on their evolutionary trajectories.
Female post-copulatory behavior in a group of olive baboons (Papio anubis) infected by Treponema pallidum
Pathogens exert a profound and pervasive cost on various aspects of primate sociality and reproduction. In olive baboons (Papio anubis) at Lake Manyara National Park, Tanzania, genital skin ulcers,

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.
Influence of Female Copulation Calls on Male Sexual Behavior in Captive Macaca fascicularis
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.
Information content of female copulation calls in yellow baboons
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.
Individuality and male discrimination of female copulation calls in the yellow baboon
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.
Female Copulation Calls in Guinea Baboons: Evidence for Postcopulatory Female Choice?
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.
Infanticide avoidance, sperm competition and mate choice: the function of copulation calls in female baboons
The hypothesis that female copulation calls promote sperm competition might act to enable females to obtain high quality sperm for their sons, and/or create paternity uncertainty, hence reducing the risk of infanticide.
Female Chimpanzees Use Copulation Calls Flexibly to Prevent Social Competition
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.
Female Barbary macaque (Macaca sylvanus) copulation calls do not reveal the fertile phase but influence mating outcome
Results provide evidence that the structure of copulation calls of female Barbary macaques does not reveal the timing of the fertile phase and conclude that in this species,Copulation calls apparently serve to enhance sperm competition and maximize paternity confusion.
The evolution of female copulation calls in primates: a review and a new model
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.
Primate copulation calls and postcopulatory female choice
The hypothesis that copulation calls are an honest signals of fertility that are used by females to encourage mate guarding by their preferred mating partners and reduce the likelihood of sperm competition is examined.
