Upside-Down Thirst

A rhesus macaque hangs head-down from an overhanging branch to sip from the pool below, its reflection completing the mirror. An acrobatic, slightly comic moment that shows just how at home these primates are in the trees. Fun fact: Macaques are superb problem-solvers with prehensile hands and expressive faces; wild troops have been documented washing food, using stones as tools, and even swimming and diving to cool off.
