Bonnet macaque Bonnet macaque The bonnet macaque also known as zati ("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. 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. It is 35–60 cm long plus a tail of 35–68 cm. Males weigh 5.5 to 9.0 kg,
Crab-eating macaque of populations due to increased wild trade and rising levels of human-macaque conflict, which are reducing overall population levels despite the species being widely distributed. Each subspecies faces differing levels of threats, and too little information is available on some subspecies to assess their conditions. The "M. f. umbrosa" subspecies is likely of important biological significance and has been recommended as a candidate for protection in the Nicobar Islands, where its small, native population has been seriously fragmented, and is listed as vulnerable on the IUCN Red List. The Philippine long-tailed macaque ("M. f. philippensis") is listed as near threatened,
