High, higher, highest. The Arunachal macaque lives at higher elevations - up to 3,500 meters above sea level - than any other species of the macaque. Winter is bitterly cold at those altitudes and nutritious food is scarce, forcing it to survive on bark and what plants are available until a more fruitful season comes again. Females remain in the groups they are born into, while males disperse. But all are finding everyday-life more and more dangerous as habitat loss and hunting reach even to the heights they call home.
