Nazar Khan, 65, is among a four-member team of "monkey whisperers" hired to stop rhesus macaques from gatecrashing the showpiece event, which begins Monday at the Indira Gandhi Indoor Stadium.The venue has an unenviable reputation. During the India Open in January a monkey was spotted in the stands, while bird droppings and debris from a nest disrupted play, drawing widespread criticism.Determined to avoid a repeat of the embarrassment, organisers have turned to a popular fix for the problem -- "monkey wallahs" or men who imitate the calls of langurs, the natural enemy of the smaller primates."We are running this business for generations, starting with street shows of monkeys and bears," Khan told AFP."But then it was banned and to keep our pot burning we took to driving away monkeys, and here we are. We kept langurs with us but then they were also banned."Though revered in the majority Hindu nation, monkeys are a major menace in the capital, often trashing gardens, offices and residences and even viciously attacking people for food.For decades monkey handlers armed with trained black-faced langurs were seen shooing away the smaller primates on the streets.But that practice ended after a court ruling barred the capture and use of the animals.
