Abstract: In primate species, mating decisions seem to be based on multiple signal elements with different roles inthe signaling of female reproductive status. Whereas some primate signals are relatively well described(e.g., sexual swellings and copulation calls), studies that simultaneously assess visual, auditory,behavioral, and olfactory cues as signals of reproductive state are rarely undertaken. We used data onvariation in sexual behaviors and sexual swellings in relation to the fertile period (estimated from thedate of swelling detumescence) from a troop of semi‐free ranging olive baboons (Papio anubis) to assesshow different signals influence patterns of mate choice. Using an objective and quantitative measure ofswelling size and color, along with detailed data on sexual behaviors from 13 cycles of nine adult females,we found thatfine‐scale variation in sexual swelling size, female behavior and copulation call rates couldadvertise the beginning of the fertile phase whereas swelling color did not. Rates of olfactory inspectionsby males also increased during the fertile phase, suggesting that olfactory signals were of interest tomales and may contain information about ovulation. There was no relationship between femalecharacteristics (age and rank) and the expression of sexual signals, except for proceptive behaviors whichincreased with female rank. Males displayed more sexual behaviors such as approaches and holding andtended to direct more ejaculatory mounts during the fertile phase. All together, we suggest that whereasall males could have information concerning the timing of ovulation through female proceptive behaviorsand swelling size, consorting males may have access to additional signals (olfactory cues). Sexualcommunication in olive baboons is consistent with a multimodal framework for fertility signaling,potentially allowing males and females to establish different mating strategies. The possible selectivepressures leading to multi‐modal signaling are discussed.
