BLOG – Hong Kong’s Feral Monkey Problem 5


Macaques are common in Hong Kong – there are around 1,965 wild monkeys in the territory and most are found in Kam Shan Country Park. Having become accustomed to interacting with humans, the population have moved further into nearby Tai Wai, terrifying residents and vandalising homes…

The Rhesus Macaques (Macaca mulatta) and Long-tailed Macaques are probable descendants of pets released in the 1920s. First spotted in 1819, the original population of native monkeys likely died out due to habitat destruction and over-hunting.

HKUST researchers also found that some macaques were released around 1913 in the hope they would eat toxic strychnos plants found around the newly opened Kowloon Reservoir.
