Deprived of their preferred food source — the bananas, peanuts and other goodies brought in by tourists now kept away by the coronavirus — hungry monkeys on the resort island of Bali have taken to raiding villagers’ homes in their search for something tasty.

Villagers in Sangeh say the gray long-tailed macaques have been venturing out from a sanctuary about 500 meters (yards) away to hang out on their roofs and await the right time to swoop down and snatch a snack.

Worried that the sporadic sorties will escalate into an all-out monkey assault on the village, residents have been taking fruit, peanuts and other food to the Sangeh Monkey Forest to try to placate the primates.

“We are afraid that the hungry monkeys will turn wild and vicious,” villager Saskara Gustu Alit said.

About 600 of the macaques live in the forest sanctuary, swinging from the tall nutmeg trees and leaping about the famous Pura Bukit Sari temple, and are considered sacred.

The Sangeh Monkey Forest typically had about 6,000 visitors a month, but as the pandemic spread last year and international travel dropped off dramatically, that number dropped to about 500.

Since July, when Indonesia banned all foreign travelers to the island and shut the sanctuary to local residents as well, there has been nobody.

Not only has that meant nobody bringing in extra food for the monkeys, the sanctuary has also lost out on its admission fees and is running low on money to purchase food for them, said operations manager Made Mohon.

The donations from villagers have helped, but they are also feeling the economic pinch and are gradually giving less and less, he said.

“This prolonged pandemic is beyond our expectations,” Made Mohon said, “Food for monkeys has become a problem.”

Food costs run about 850,000 rupiah ($60) a day, Made Mohon said, for 200 kilograms (440 pounds) of cassava, the monkeys’ staple food, and 10 kilograms (22 pounds) of bananas.

Frequently, monkeys wander into the village and sit on roofs, occasionally removing tiles and dropping them to the ground. When villagers put out daily religious offerings of food on their terraces, the monkeys jump down and make off with them.

“A few days ago I attended a traditional ceremony at a temple near the Sangeh forest,” Gustu Alit said. “When I parked my car and took out two plastic bags containing food and flowers as offerings, two monkeys suddenly appeared and grabbed it all and ran into the forest very fast.”
