Our Vision
Our vision is a world where orangutans are free from the threat of extinction and can live in the wild, unharmed by humans.
back to their home.
our two sanctuaries.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

A throwback to Bumi's rescue and his early days in BOS Foundation's care.
Bumi represents the fate of many of our rescued babies, who come to us with traumatic experiences.
Yet, there is always hope. Today, Bumi is on a Pre-Release Island, just one step away from freedom.
However, we can't do our lifesaving work without you! We need your support to give orphans like Bumi the second chance they so much deserve.
How can you help? The best way is by adopting one of our orphaned orangutans here: orangutans.com.au/me#tbtu#secondchancet#AdoptAnOrangutand#SaveOrangutans##Conservations#notapetv#love #supportuslove #supportus

Close your eyes and listen...
The sound you hear echoing throughout the forest is known as the ‘Long Call’.
Male adult orangutans with cheek-pads use this call to attract the attention of female orangutans and to prevent other males from entering their territory.
You can hear long calls from over 1.5 kilometres (about a mile) away. In some cases, adult males make spontaneous long calls in response to disturbances, such as being startled by a falling tree.
The long call itself typically consists of three parts: an initial grunt or grumble, followed by a climactic section, and concluding with a low gurgle. This final part is often accompanied by a frothy or bubbly mouth.
However, some orangutans will omit the grunt or grumble entirely and immediately start with the climactic part.
Want to hear a long call live in the Bornean rainforest? Join our Orangutan Enrichment Volunteer Program! We still have spots available for our trips in January, February and March. Discover more here: experienceborneo.org/orangutan-volunteer-program (or link in bio)
