Yellow baboons are quite common in Shimoni and are commonly regarded as infamous pests that are brazen enough to steal food from inside a human dwelling. Yet however obnoxious they may become they remain fascinating from a primate behavioural standpoint. Mating behaviour in particular, is especially interesting and has even been observed from the back garden of the GVI Shimoni house.

Mating occurs year round in Yellow baboon troupes although not all females come into estrus at the same time. Resource availability and nutrition play a large role in determining the timing of mating activity so that it most often occurs when food availability is quite high, such as after the rainy season. Receptive females exhibit two physical signs: menstruation and red swelling of the hairless area of the rump. Females are most swollen at the peak of their sexual receptivity. Once pregnant, the gestation period lasts 180 and days and the average interbirth interval is 1.78 years although males may stimulate estrus in females after committing infanticide.
