Muna-Buton macaque Muna-Buton macaque The Muna-Buton macaque ("Macaca ochreata brunnescens") is one of seven Sulawesi macaques in Indonesia. It is only found on two small islands off the south-east coast; the islands of Buton and Muna. This Old World monkey is diurnal and arboreal, although it can spend significant amounts of time on the ground. It is black with grey "boots" and a brownish colour to the fur on its back. Like other Sulawesi macaques it has a reduced tail of only about 35mm in length. Its body is about 475 - 495mm in length. The Muna-Buton macaque feeds on fruits for
Crab-eating macaque durians such as "Durio graveolens" and "D. zibethinus", and are a major seed disperor for the latter species. Although the species is ecologically well-adapted and poses no threat to population stability of prey species in its native range, in areas where the crab-eating macaque is not native, it can pose a substantial threat to biodiversity. Some believe the crab-eating macaque is responsible for the extinction of forest birds by threatening critical breeding areas as well as eating the eggs and chicks of endangered forest birds. The crab-eating macaque can become a synanthrope, living off human resources. They are known to
