Sexual harassment among captive patas monkeys (Erythrocebus patas)

Short Communications


Observations of the sexual harassment occurring within a captive group of patas monkeys are reported. Immature males performed most harassing attacks, while immature and adult females were infrequent harassers. The adult male of the group appeared to be the object of the majority of attacks, and on occasion the male’s copulatory behavior was modified by harassment. It is hypothesized that the harassing attacks performed by immature patas monkeys may be based upon (a) the excitatory effect of witnessing adult sexual interactions, and (b) the approach/withdraw conflict experienced during close approach to the adult male. The preservation of the one-male group structure is suggested as a possible function of sexual harassment.
