Effect of Provisioning on the Temporal Variation in the Activity Budget of Urban Long-Tailed Macaques (Macaca fascicularis) in West Sumatra, Indonesia.
Ilham K., Rizaldi, Nurdin J., Tsuji Y.

We studied the behavioral ecology of provisioned long-tailed macaques (Macaca fascicularis) in Padang, West Sumatra, Indonesia, to examine how temporal changes in food provisioning within a day affect macaque activity. We conducted a field survey from October 2015 to January 2016 at two different sites: Gunung Meru (GM) and Gunung Padang (GP), where macaques receive high and low provisioning, respectively. The time budgets of macaques significantly differed between study groups. At GM, macaques spent more time resting, feeding, acting out agonistic behaviors, and less time moving and searching for food, than the macaques at GP. Diurnal activity patterns significantly changed within a day. The short-term change in activity of the macaques was closely related to the number of tourists: they spent a greater time feeding and searching when more tourists came to feed the monkeys, while time for grooming decreased. Our result showed that the ability of the macaques to adjust their activity in response to the number of tourists (that is, provisioning patterns) indicated their behavioral flexibility. Our result may aid the management strategies to reduce human-macaque conflicts, which has become a major problem in Padang.
