Orangutan Progress in Kehje Sewen!

Independent Leke

We recently received information on how Leke is progressing and were interested to hear whether she was still spending time with Agus. Well apparently she is not. This week, Leke was seen exploring the forest by herself. In the morning she generally woke up at around 7 am and immediately started to look for food. She has been eating many kinds of foods such as rattanand liana shoots, fruit, cambium, termites and so on.  Despite being seen alone most of the time, the Monitoring Team once observed her and Agus copulate before they went their own ways again. Noel was also observed attempting to engage Leke in copulation and after several attempts, he finally succeeded.

Leke holds a respected place amongst the orangutans in Kehje Sewen. When Casey and Yayang tried to aggravate her, Leke stood her ground and the duo retreated. Maybe that was the reason why Leke no longer joined Yayang and Sayang during fruit feeding sessions.

Leke seems to be getting to know Kehje Sewen more each day. She is skillful in foraging for food and building nests.

Mother and Daughter Yayang-Sayang

Meanwhile, how are Yayang and Sayang?  Based on our observations, they both look healthy and have adapted well to Kehje Sewen. Usually when Yayang wakes up in the morning, she doesn’t leave her nest right away. Patiently she waits for Sayang to wake up so they can forage together. Yayang often helps Sayang in looking for and selecting foods. She has also been seen helping her daughter bridge gaps between the trees so Sayang can move freely. Yayang always gives Sayang a chance to walk ahead with her following closely behind. Based on our observations, Yayang and Sayang are consuming several forest foods such as termites, lianas, rattan shoots, Baccaurea sp., figs etc.

The lovely mother-daughter.

Sayang still sleeps and shares a nest with her mother. Sometimes if she wakes up earlier than her mother, she will nurse for a while before playing by herself in the trees. If she sees the Monitoring Team, she will generally throw branches at them.

Sayang seems to be becoming more and more independent. Several times, the team recorded Sayang looking for her own food, even though Yayang was always watching. Despite this budding independence, Yayang will still carry Sayang around while looking for food. Sayang having just turned 5 years old in April, is still being guided by her mother and learning the refined skills she needs to become independent.

Agus and Friends

Agus seems to have no shortage of friends. He and Leke were seen mating and then made their nests in a same tree. The next day, Leke moved away from Agus and Agus also moved on and continued  feeding alone. As a matter of fact, he ate a lot. He tried many kinds of fruit, shoots and young leaves and travelled continuously through the trees.

At one point Casey approached Agus who for some reason stayed away from her. Casey, who looked healthy, then continued her own journey.

In addition to Agus and Casey, the Monitoring Team also observed Upi. Upi was found feeding on liana fruits and shoots of different species.

In the Gunung Belah area where Upi was located, the Team recorded signals from Acong and Mayang’s transmitters, but couldn’t pinpoint them. Oneng and Nila’s signals were also recorded. The Team will continue to monitor these orangutans and obtain direct observations so we can review their health and progress.

Siwi who was observed in the Kali Tengah area also looked healthy.  She was found at around 11 in the morning whilst feeding. These orangutans are doing well in their new home Kehje Sewen.  We’ll watch and report on their progress and hope they will continue to explore even further!
