The Hand That Feeds the Monkey: Mutual Influence of Humans and Rhesus Macaques (<Emphasis Type="Italic">Macaca mulatta</Emphasis>) in the Context of Provisioning

Historically, humans and other primates (primates henceforth) have coexisted across cultures and contexts, and many primate populations use anthropogenic food sources as their main or supplementary food. While primates may actively forage for such food, they are also directly provisioned by humans in many regions. Ethnoprimatology views humans and primates as cohabitants of integrated socioecological spaces who mutually influence each other’s ecologies and social lives. We contextualized provisioning of primates by humans within an ethnoprimatological framework and examined if the availability of anthropogenic food affected primate diets or the amount of time primates spent in anthropogenic habitats and whether primates influenced the human act of provisioning. To this end, we used scan sampling on a group of rhesus macaques across a year, and conducted interviews with 86 people who paused at a nearby tea shop for refreshments. We found that the macaques’ consumption of natural resources and dietary diversity decreased, and they spent more time in human-modified habitats when provisioned food was available. We also found that particular behaviors of the provisioned macaques stimulated provisioning by humans. Our findings show that provisioning influences macaque feeding ecology and habitat use, and that the behavior of the macaques themselves drives people to provide them with food subsidies, illustrating a complex web of interactions between the sympatric species.
