A pack of wild monkeys who have been pestering residents in the New Territories have been stopped in their tracks after three males - including their leader - were trapped. The Agriculture, Fisheries and Conservation Department began placing traps in Tai Wai in April after receiving over 30 complaints. Although officers had hoped to have more success, they said they had kept the monkeys away from residential neighbourhoods. 'So far it has solved the problem,' said Tang Wing-cheong, a member of Sha Tin District Council. 'We haven't had monkeys attacking the public recently.' One of the monkeys caught is believed to be the alpha-male, or leader, of the pack because of his size. About a dozen monkeys had waited outside the cage to let him eat the fruit placed inside. They all watched as he was trapped. 'The pack has seen its high-ranking leader taken away,' said Wong Che-lok, a wetland and fauna conservation officer. 'So they know that area is dangerous.' The three monkeys are being kept at the New Territories North Animal Management Centre, where the government keeps wounded wild animals. They will be relocated to a zoo or primate centre on the mainland or overseas once a placement is found, Mr Wong said. The wild pack of about 30 monkeys in Tai Wai started appearing in villages and other residential areas of Tai Wai last October. Hong Kong has about 1,450 monkeys, mostly in Kam Shan Country Park. The ones who live in country parks can wander freely and are fed by licensed feeders. The monkey population has been growing by about 5.5 per cent to 7.8 per cent a year. The Agriculture, Fisheries and Conservation Department is testing a contraceptive injection on 37 monkeys, Mr Wong said. If no side effects are found, the department would use it to control the monkey population.
