Monkeys are revered by Hindus because of their association with the monkey god Hanuman, but they become a problem for the human population as they run free through many Indian cities.
Large groups of macaques around the capital have attacked politicians and destroyed official documents.
The practice of driving the marauding monkeys off with their larger langur cousins, accompanied by handlers, was outlawed in late 2012, when it became illegal to keep the langurs in captivity.
Now, dozens of “monkey wallahs,” which roughly translates to “monkey men,” grunt, hoot and screech in their best langur impersonations to scare off the macaques.
The Times of India reports the monkey impersonators have proved to be effective in their new roles and are paid between $115 and $150 per month for their part-time efforts.
