It is planned to deploy people trained to mimic the sounds of gray langur monkeys – which scare smaller monkeys – at various locations.

There is a huge monkey population in Delhi, and authorities hope these measures will prevent the animals from disrupting the summit.

The G20 leaders will meet in India on September 9 and 10.

Langurs are aggressive monkeys with long tails and dark faces. When other monkeys are spotted, they are typically released by specially trained handlers on leads.

Langur cut-outs are being placed in heavily monkey-infested areas, a senior official told PTI news agency.

According to Satish Upadhyay, 30-40 trained people who can mimic langur sounds will be deployed at hotels where delegates will stay as well as in places where monkeys have been sighted.

Additionally, authorities are providing monkeys with food at designated sites in an effort to discourage them from lingering.

In the past, authorities in Delhi have used real langurs or mimics of langurs to scare away monkeys, including during the 2010 Commonwealth Games.

To scare away monkeys from the parliament and other government buildings in 2014, authorities hired 40 professional langur impersonators.

In the past, parliament officials used real langurs for the same purpose, but stopped after animal rights activists complained that holding monkeys captive was cruel.
