Raymond Encounters Bungan in the Kehje Sewen Forest

July 28, 2016. Posted in Article

Our PRM team from Camp Nles Mamse recently monitored Raymond’s activities over several consecutive days to see how he was adapting to life in the Kehje Sewen Forest following his release on May 28.

Raymond was observed eating a variety of forest fruit species, including jackfruit (Artocarpus sp.), Ficus sp., and a ginger root (Etlingera sp.) He was actively foraging and moving through the trees and lianas, clearly enjoying his new life.

After climbing down to grab some a ginger root, he busied himself building a couch-like mattress made from piles of twigs and leaves. He rested comfortably on his ‘couch’ for a while before returning to the trees to explore.

The next day, the team caught up with Raymond and followed him again, this time interrupted by unfavourable weather and rainfall. Raymond cleverly grabbed several leafy branches to cover his head, just like an umbrella.

After the rain stopped, Raymond returned to foraging and kiss-squeaked every now and then to show his displeasure with human presence.

Suddenly, the team noticed movements in the forest and quickly checked telemetry signals to find out if it was another orangutan approaching. The movements turned out to be from Bungan, a female the BOS Foundation released in December 2015.

Raymond did not appreciate the company and quickly departed. However, Bungan seemed determined to get to know Raymond and chased him for a few hours. The team followed them until Raymond finally made peace with Bungan’s presence, and they both stopped to sit in the same tree. They then hugged and sat together to eat forest fruits.

They were still together the following day, and stayed close to one another. When Raymond started to build his nest for the night, Bungan chose to build hers in a nearby tree.

We are delighted to see this friendship develop between Raymond and Bungan, and hope it will result in another natural birth in the Kehje Sewen Forest.

Peace and Papayas Among Friends

July 19, 2016. Posted in Article

On a beautiful morning in the Kehje Sewen Forest, our team recently set out to monitor Lesan and her baby. The pair was found not far from Camp Lesik, enjoying some papaya on the ground. Both mother and infant appeared to be happy and healthy.

Suddenly, movements could be heard coming from up in the trees. The team tried to identify the approaching individual by telemetry signal, but were unable to pick up a signal – this could indicate an orangutan released quite some time ago with an exhausted transmitter. Through observing the approaching orangutan’s physical characteristics, the team soon discovered it was none other than Juminten (with her round face and distinguishable hairline)!

Released in 2013, Juminten was last seen by our team on July 8 last year, when she was observed hanging out with Mona, another adult female released the same year (Read the full story here: A reunion with Mona and Juminten).

Juminten looked very interested in the papaya that Lesan and her baby were eating, and she moved cautiously closer. Lesan remained calm and seemed unfazed by larger Juminten’s presence – so much so, she gave her the chance to join them.

After finishing her papaya, Juminten approached Lesan and her baby again and spent some time with them before continuing her journey through the forest alone.

Lesan then took her baby and climbed up in the trees to build a nest and rest together.

This friendly and peaceful interaction between released orangutans indicates to us they are living happily and comfortably in the Kehje Sewen Forest.

Angely Enjoys Her New Life in the Kehje Sewen Forest

July 12, 2016. Posted in Article

Our PRM team from Camp Nles Mamse has been tracking Angely and is happy to report she is adapting well to her new home in the Kehje Sewen Forest. Angely has been observed feeding well on breadfruit (Artocarpus sp.) and ficus fruits, which seem to be among her chosen favourites.

From the moment she leaves her nest in the morning, Angely goes in search of forest foods. She spends hours in the trees eating which is very encouraging to see.

After feeding, Angely will travel deeper into the Kehje Sewen Forest. She is quick and agile, and more often than not, our team has to make a fast dash just to catch up with her and keep monitoring her activities. At midday, Angely usually builds herself a nest to rest in for a couple of hours.

Our PRM team have noted that Angely starts building her night nests from about 4.30 p.m. daily and cleverly stocks them with ficus fruits before retiring for the night. At sunrise, she eats her already prepared fig breakfast in bed before leaving her nest for another day in the forest.

It is heart-warming to see Angely living in the Kehje Sewen Forest. We hope the other orangutans in our care at Samboja Lestari and Nyaru Menteng will have the same opportunity to live happily in the wild, just like Angely.
