The Graduates
Orangutans in the Orangutan Outreach Adoption Program are considered “graduates” once they complete forest school, move to a pre-release island, or are released to freedom in the forest.
Each event is a cause for celebration, although we are always a bit sad that we can no longer follow the progress of these special red apes. You can read about our beloved graduates below.
Note: These orangutans are no longer available for adoption, but the updates and online materials of recent graduates will remain available for a short period of time after the orangutan graduates.
Our adoption program was founded in 2007 and over the course of time we have had many graduates. We have also had several deaths. You can read about them below in our ‘In memoriam’ section.

Covita was soon placed with an orangutan foster mother named Paini. The two lived together on a rehabilitation island on the grounds of the YIARI orangutan center where Paini taught Covita all the skills she needs to live in the forest. We were so happy when Covita and Paini were released together to freedom in Bukit Baka Bukit Raya National Park on June 26, 2023!

Cutie Elo arrived at Borneo Orangutan Survival (BOS) Foundation’s Nyaru Menteng care center in May 2012. After learning many social and survival skills, Elo completed Forest School. In 2019, at age 8, this clever boy was moved to the final stage of rehabilitation on pre-release islands. By 2023, Elo had spent time on Bangamat and Kaja Islands. Elo had a tendency to venture far into the forest island interior, where he was hard to track. Elo was last seen in January 2024. It is possible this adventurous guy chose to release himself back to the wild forests.
Pungky
Dashing Pungky was rescued in 2010 and cared for by International Animal Rescue Indonesia (YIARI). He completed his rehabilitation at the YIARI orangutan center. In 2016, Pungky completed his skills training on a pre-release island on the grounds of the center. This special guy was released to freedom into Bukit Baka Bukit Raya National Park in March 2018. He was spotted several years later in the company of a female orangutan!

By 2017 Mimi had truly blossomed, mastering the skills necessary to live in the forest. After spending several seasons on a pre-release island at the YIARI center, Mimi was deemed ‘ready for release’. She was returned to freedom in the forest in Spring 2017. Her release into Bukit Baka Bukit Raya National Park was a wonderful moment!
Gober & the Twins
Special lady Gober entered the Sumatran Orangutan Conservation Programme (SOCP) Quarantine Center in November 2008. She needed extra care as she was blind due to cataracts. In 2009, Gober was introduced to a blind male orangutan named Leuser. Unexpectedly, Gober became pregnant and in February 2011 she delivered healthy twins, male Ganteng and female Ginting. The infants thrived under Gober’s care. In 2012, following a surgical procedure on her cataracts, Gober’s sight was partially restored! On December 5 2014, Gober and the twins moved to SOCP’s Jantho reintroduction site and they were released to freedom on January 5 2015. Sadly, Ginting was found deceased in the forest on February 5 2015. Ganteng, who had been separated from his mother during the release, took time to adjust to the forest on his own. By December 2015, Ganteng was 5 years old and doing well in the forest. We like to think he has come across his mom since then!
Kesi
Endearing Kesi was brought to Borneo Orangutan Survival (BOS) Foundation’s Nyaru Menteng center in September 2004. She was barely three months old and her left hand was missing. She was one of the tiniest and most delicate babies the staff had ever seen. Through her years in Forest School, Kesi developed into a more independent and active orangutan, never letting her disability hold her back. This lovely girl became a fan favorite on the hit series Orangutan Island and Orangutan Jungle School. Kesi graduated Forest School and proceeded to the pre-release island phase of rehabilitation in March 2014. She spent time on Palas, Bangamat, and Kaja islands. Kesi was last seen on an island in 2019. We like to think that Kesi decided to release herself to freedom.
Lomon
Clever Lomon came to Borneo Orangutan Survival (BOS) Foundation’s Nyaru Menteng facility in April 2006 at around 4 years of age. He progressed quickly through the levels of Forest School and was the star of the BBC Orangutan Diary docu-series. Lomon became one of the most dominant male orangutans in his group by the time he completed Forest School. He then moved to the BOS socialization complex in 2010. In December 2012, Lomon moved to Bangamat pre-release island to perfect his skills. Then, in April 2016, he was released to freedom in the Batikap Conservation Forest. Lomon was the 200th orangutan released from Nyaru Menteng!
Fio
Bright little Fio was brought to Borneo Orangutan Survival (BOS) Foundation’s Nyaru Menteng facility in 2004. She weighed barely 4 pounds and was approximately 6 months old. Fio quickly became energetic and independent, and her skills developed quickly. Under loving care, she grew, developed and thrived. Fio completed Forest School in 2012 and moved to the pre-release stage of rehabilitation in November 2014. She spent time on Palas, Bangamat, and Kaja islands but she had bouts of illness and returned to the Nyaru Menteng clinic. Fio moved to the BOS socialization complex in 2024.

He completed rehabilitation at Borneo Orangutan Survival (BOS) Foundation’s Nyaru Menteng facility. When the Orangutan Diary docu-series aired on BBC, Grendon became a full-fledged TV star. Viewers all over the world had the opportunity to see him grow and develop as the series progressed. Grendon completed Forest School and moved to the BOS socialization complex in Fall 2011. In April 2017, Grendon moved to Kaja pre-release island to perfect his survival skills. Grendon was released to freedom in the Bukit Baka Bukit Raya National Park in December 2018!

Lovable Dodo was brought to Borneo Orangutan Survival (BOS) Foundation’s Samboja Lestari center in 2007 by Indonesian forestry officials when he was less than a year old. Dodo thrived in Baby School and by Summer 2009, he had begun Forest School Group 1. After making excellent progress and developing many skills over the years, Dodo completed Forest School. In April 2017, Dodo moved on to the pre-release phase of rehabilitation on Juq Kehje Swen island. Dodo was last seen on the island in 2019 and we believe Dodo decided to release himself to freedom in the nearby forest.
In Memoriam
Luna
Enchanting Luna was the youngest of the group and the smallest of the bunch. With her fluffy hair, her big brown eyes, and her Mona Lisa smile, she stole everyone’s hearts. Our little angel disappeared in early April 2011, under suspicious circumstances, from the Sintang Orangutan Center in West Kalimantan (Borneo). This caused us to question the very notion of what it means to rescue an orangutan.
Learn more about Luna’s questionable disappearance here.
Nadya
Precious Nadya was a beautiful little orangutan who was rescued in June 2014 when she was around 2 years old. She was taken to Sumatran Orangutan Conservation Programme (SOCP) center where she received much tender loving care. Nadya was a true sweetheart. Over four years Nadya developed from a timid baby into a confident young lady. In April 2018 Nadya was transferred to the SOCP Jantho Orangutan Reintroduction Center for advanced skills training. Nadya fell ill and returned to the SOCP Quarantine and Rehabilitation Centre for intensive care. The little sweetie passed away on July 17 2018 due to bronchopneumonia and malaria. Nest in peace, dear one.
Momo
Momo was originally rescued alongside his best friend Mimi in 2010. The two were inseparable after their ordeal in captivity. They were confiscated from animal smugglers in the West Kalimantan city of Sintang. They were malnourished and being kept locked up in a bathroom overlooking a sewer. They would eventually be cared for by International Animal Rescue Indonesia (YIARI). Momo passed away from internal organ failure after a long period of illness. We like to think his spirit is swinging in the forests of Buki Baka Bukit Raya National Park alongside his beloved Mimi… Nest in Peace, Momo…
