Bali's thieving monkeys can spot high-value items to ransom
Study finds macaques go for tourists’ electronics and wallets over empty bags and then maximise their profit

At the Uluwatu temple in Bali, monkeys mean business. The long-tailed macaques who roam the ancient site are infamous for brazenly robbing unsuspecting tourists and clinging on to their possessions until food is offered as ransom payment.
Researchers have found they are also skilled at judging which items their victims value the most and using this information to maximise their profit.
Shrewd macaques prefer to target items that humans are most likely to exchange for food, such as electronics, rather than objects that tourists care less about, such as hairpins or empty camera bags, said Dr Jean-Baptiste Leca, an associate professor in the psychology department at the University of Lethbridge in Canada and lead author of the study.
Mobile phones, wallets and prescription glasses are among the high-value possessions the monkeys aim to steal. “These monkeys have become experts at snatching them from absent-minded tourists who didn’t listen to the temple staff’s recommendations to keep all valuables inside zipped handbags firmly tied around their necks and backs,” said Leca.
After spending more than 273 days filming interactions between the animals and temple visitors, researchers found that the macaques would demand better rewards – such as more food – for higher-valued items.
