Formosan rock macaque  (Macaca cyclopis)

The Formosan rock macaque is native to the island of Taiwan, where it primarily occupies the mountainous areas in the north-eastern and south-western parts of the island (4) (5). Although the species is thought to have once been associated with coastal areas, it is now largely confined to inland hills because of human activity (5). This macaque has also been introduced to a few small islets in Japan, where it hybridises with the Japanese macaque (M. fuscata) (6).

Primarily found in mixed coniferous-hardwood temperate forest, as well as bamboo and grassland, at elevations between 100 and 3,600 m above sea level (5).
