Formosan rock macaque the 22 species of the genus "Macaca" that are found in southern and eastern Asia as well as northwestern Africa, the Formosan macaque is endemic to the island of Taiwan (area: 36,000 km). Formosan rock macaques live in mixed coniferous-hardwood temperate forest, as well as bamboo and grassland at 100-3600m (328-11,812 ft). The social structure of macaques is generally characterized as often occurring as a large stable multimale-multifemale troop. Formosan macaque is considered to be female-bonded which is similar to other species in the genus "Macaca". Based on the study of Hsu and Lin, the average overall sex ratio was
