BOS Nyaru Menteng: Candidate Profiles for the 32nd Orangutan Release

November 18, 2019 โ€” Eighteen lucky orangutans from BOS Nyaru Mentengโ€” including one mother-baby pairโ€” are being released back into the forest! Meet the candidates! Good luck everyone! ๐Ÿ™‚

1. DEA

Dea was born in the Nyaru Menteng quarantine complex on 27 October 2009. Following her birth, Dea and her mother, Du, were kept together in the quarantine complex until they could be transferred to a pre-release island.

On 11 March 2014, Dea and Du were moved to Palas Island. Dea, four years old at the time, had already developed a highly curious nature. She enjoyed exploring the forest and tended to avoid humans. A few short years later, she no longer depended on mother Du. In light of her new independence, Dea was moved to Bangamat Island on 19 April 2018, to further develop her survival skills and natural behaviours.

Dea is now 10 years old and weighs 22.9 kilograms. She has long, thick hair and a piercing gaze. It is only a matter of days before Dea will be enjoying true freedom in the lush wilderness of the Bukit Baka Bukit Raya National Park.

2. DONK

Donk was rescued through a joint operation by the Central Kalimantan BKSDA and BOS Foundation Nyaru Menteng from Padas Village, East Kotawaringin Regency, Central Kalimantan. He arrived at Nyaru Menteng on 8 April 2009, when he was four years old and weighed 19 kilograms.

After completing the mandatory quarantine period, Donk joined Forest School and later entered the pre-release stage of the rehabilitation process on Kaja Island in April 2017. Highly alert by nature and weary of new people, Donk prefers to spend his time alone as he explored his island home.

Donk is now 14 years old and weighs 32 kilograms. This independent male is undoubtedly ready to live freely in the forests of the Bukit Baka Bukit Raya National Park as a true, wild orangutan.

3. IRIANA

Iriana arrived at Nyaru Menteng on 17 January 2015, when she was three years old and weighed 7.8 kilograms. Her rescue was carried out in an area that had been newly cleared for oil palm production, in Baun Bango Village, Katingan Regency, Central Kalimantan. Upon rescue, Iriana displayed wild behaviours and kiss-squeaked in distress whenever a human approached her. Despite these wild tendencies, Iriana had to undergo rehabilitation before being released due to the fact she was found without a mother.

After passing quarantine, Iriana started the rehabilitation process when she was moved to Kaja Pre-release Island on 6 July 2017. Due to her firm dislike of humans, she developed a highly alert nature and preferred to roam alone. While not a dominant figure, Iriana is capable of defending herself when required.

Though not aggressive, Made Ayu always does her best to avoid humans. She would spend her days exploring and socialising with other orangutans. While on Kaja Island, Made Ayu was frequently observed with a male orangutan named Sydney.
