A handler in Indonesia has a unique way to summon hundreds of wild apes.

The distinctive sound of a buffalo horn blown by the handler named Detim Manik makes hundreds of wild monkeys come out of the forest to take the food he provides.

This is Manik's daily life as a monkey handler and tour guide in the Sibaganding Monkey Forest tourist park in the Sibatu Loting forest, Simalungun district, North Sumatra province.

According to 44-year-old Manik, there are four types of apes that inhabit this forest, including gibbons, monkeys, macaques and kiak-kiak.

Monkeys are fed with bananas and seeds such as corn. Within a day, Manik provides two sacks of bananas and several packages of corn.

"They were called here so that they would no longer take to the streets. If they actively took to the streets, they were often run over by cars and electrocuted," Manik added.

Increasing population and depletion of food in their habitat in the forest makes monkeys go down the highway to find food.

Currently, the source of food from monkeys comes from tourists who come and buy bananas provided by the manager of the tourist sites.

The footage was filmed on July 4.
