Month: January 2018

Ingrid and Ivan. How are they adjusting to life in the forest?

Our Post-Release Monitoring team from Nles Mamse Camp in the Kehje Sewen Forest recently set out to observe mother-infant pair Ingrid and Ivan, who were released on December 4, 2017. The team headed to the location where Ingrid and Ivan were last detected through their individual radio-tracking signals, then took a long hike uphill in the direction of their current signals. Ingrid, with young Ivan close beside her, were located in a tree at the top of the hill. The PRM team quickly began collecting data, while maintaining a safe distance to avoid disturbing the pair.

Ingrid and Ivan appeared in good health, and were observed consuming a large amount of forest fruit. Once satisfied, the two climbed down to the forest floor and searched for more food sources, including shoots, ants and termites. While they were preoccupied feeding, Angely showed up: Ingrid and Ivan didn’t seem to mind, and the three spent some time together. A short time later, Angely climbed up into the trees to continue her exploration of the forest. Ingrid and Ivan also climbed back up into the trees, and built a night nest. The two appeared to settle down for the evening, so the team finished the day’s observations and headed back to camp.

Ivan Beginning to Show Independence

Our team conducted nest-to-nest observations on Ingrid and Ivan for one whole month following their release, and have witnessed the pair thriving in the forest. Ingrid has spent most of her time eating, exploring the forest, and building nests. It is wonderful to see how quickly Ingrid has adapted to her new home.

Just like his mother, 4-year-old Ivan has embraced life in the wild. The once clingy Ivan is now more active, and will even move a safe distance from Ingrid. He no longer cries out, and is starting to find food for himself. He loves to play in the trees and is curious of the new things he finds. Often the team have heard cracking sounds above only to find that it was Ivan who was attempting to construct a nest. He is learning new skills quickly; which is the positive sign we always hope to see in reintroduced orangutans.

Alba will soon be nesting in the trees!

The world’s only known albino orangutan, Alba, is destined for the forest and will start her new life on a 10-hectare forest-island home by the end of June. 

Like humans, all orangutans are unique individuals. There is one orangutan, however, that completely stands out from the crowd. Alba is the only albino orangutan known in the world. She was aptly named after the Latin word for “white,” in a naming competition run by BOS Foundation in May 2017.  Soon, Alba will be moved to a special man-made island that encompasses 10 hectares of natural habitat, so she can live a life of freedom, while remaining protected from human threats.

Alba was rescued in a joint effort by the BOS Foundation and the Central Kalimantan Natural Resource Conservation Agency (BKSDA) on 29 April 2017, in Kapuas Regency, Central Kalimantan. The news of her discovery attracted international attention. Her plight deeply touched the hearts and minds of people from across the world, and left many wondering how her story will progress.

Even though Alba has good experience living in the wild – a trait that would usually mean she could be translocated quickly without a lengthy rehabilitation process – her albinism makes her a very special case, requiring a bespoke rehabilitation strategy. The symptoms of albinism – namely the lack of the pigment, melanin, in her hair and skin – can lead to health complications, such as, poor eyesight, poor hearing, and skin cancer, and make her more vulnerable to hunting or predation.

Alba will be accompanied on her new forest-island home by three other orangutans – Radmala (female, aged 4), Kika (female, aged 6), and Unyu (male, aged 4) – all of whom have been introduced to Alba and they have bonded well together. All show a certain level of wild behaviour and can be categorised as semi-wild.

Once on the island, Alba and the others will have full-time monitoring and security provided by staff who will conduct patrols and collect data on their behaviour and health. Additionally, our staff will record which orangutans are seen at the feeding platform, where supplementary foods are provided twice a day.

Construction works on the island is mostly completed and running at full speed. The canal that serves as a natural border was completed near the end of 2017. Construction of security and monitoring infrastructure is also underway; we hope to complete this by the end of February. However, there is still time to donate to Alba and her new home. The collected funds will be used to build feeding platforms and security posts on the island, and help us to provide her with their daily needs. With your support, Alba and her friends can get to know their wild side on the island.

BOS expect to conduct Alba’s relocation on June 2018 by the latest.
