Calling Siamang and Monkey From Forest With Trumpets

A man named Detim Manik has a unique way of calling gibbons and wild monkeys from the wilderness. The location is in the Monkey Tourism Park, also known as the Sibaganding Monkey Forest, which is a natural tourist attraction in the Lake Toba National Tourism Strategic Area, Parapat, Simalungun Regency, North Sumatra, Indonesia.

Detim Manik seemed to call gibbons and monkeys by blowing trumpets made of buffalo horns.

After the trumpet sounded, after 5 minutes, gibbons and monkeys were seen coming to the location where Detim Manik blew the trumpet.
