Grooming Macaques, Kam Shan (金山)

Rhesus Macaque (Macaca mulatta) One of the most widespread primates on Earth, rhesus macaques are highly social Old World monkeys whose mutual grooming reinforces troop bonds and hierarchy. Around 1,800 wild rhesus macaques inhabit Hong Kong’s Kam Shan (金山) Country Park year-round, descendants of a population released in the 1910s that has thrived in the forested hills ever since.
