The bonnet macaque (''Macaca radiata'') is a macaque endemic to southern India. Its distribution is limited by the Indian Ocean on three sides and the Godavari and Tapti Rivers along with a related competing species of rhesus macaque in the north.〔〔Fooden, Jack (1988) (Taxonomy and Evolution of the ''Sinica'' Group of Macaques: 6. Interspecific Comparisons and Synthesis ). Fieldiana Zoology (New Series) 45.〕 Land use changes in the last few decades have resulted in changes in its distribution boundaries with the rhesus macaque, raising concern for its status in the wild. This Old World monkey is a diurnal animal.〔(Old World Monkeys ). Animalcorner.co.uk (2004-01-01). Retrieved on 2013-04-25.〕 It is 35–60 cm long plus a tail of 35–68 cm. Males weigh 5.5 to 9 kg, females 3.5 to 4.5 kg. Captive monkey can live up to 35 years.〔Brown, M. (2008) (Macaca radiata ). Animal Diversity Web.〕 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.〔(bonnet monkey ). Merriam-Webster. Retrieved on 2013-04-25.〕 Two subspecies of bonnet macaques have been identified: ''M. r. radiata'' and ''M. r. diluta''.〔 == Behavior == The bonnet macaque has a very wide range of gestures and behaviors, which can be easily differentiated. 'Lip smacking' is one of the most common affiliative behaviors, where one individual may open and close its mouth in rapid succession, with its tongue between its teeth and its lips pressing against each other, giving an audible sound. A 'grimace' is the most common gesture of fear or submission that a subordinate shows to a dominant individual during aggressive encounters. It consists of pulling back its upper lip, showing its upper teeth. They also have distinct alarm calls for predators such as python and leopard.〔(Friends Help More Promptly, at Least in Monkeys ).
