Bonnet macaque females 3.5 to 4.5 kg. Captive monkey can live up to 35 years. The bonnet macaque feeds on fruits, nuts, seeds, flowers, invertebrates, and cereals. In southern India, this macaque exists as commensal to humans, feeding on food given by humans and raiding crops and houses. Two subspecies of bonnet macaques have been identified: "M. r. radiata" and "M. r. diluta". The bonnet macaque has a very wide range of gestures and behaviors, which can be easily differentiated.

Barbary macaque females differ from other non-human primates in that they often mate with a majority of the males in their social group. While females are active in choosing sexual associations, the mating behaviour of macaque social groups is not entirely determined
