Arunachal Macaque

The Arunachal macaque is a large, stocky monkey with dense dark-brown fur, a paler upper body and forelimbs, and a conspicuous yellow forehead patch containing a dark hair whorl. Its short tail, measuring roughly 39–45% of head-and-body length, helps distinguish it from related macaques. The only formally measured adult male was 82.4cm long, including a 26.4cm tail, and weighed 15kg. Males are larger and more robust than females. (Animal Diversity Web)

This diurnal macaque forages mainly on the ground but sleeps in trees. Groups contain males, females and young and have been recorded with 5–60 members. Its predominantly plant-based diet includes leaves, pith, fruit, flowers, bark and stems, with occasional invertebrates; Erythrina variegata becomes particularly important in winter. Confirmed records are from Arunachal Pradesh in India, where it occupies high-elevation forest and also uses disturbed agricultural landscapes. Its occurrence in adjoining Tibet and Bhutan remains unconfirmed. (Animal Diversity Web)
