News from the Forest

Nest-to-nest monitoring by our team in Camp 103 is a long-term program to enable us to observe the newly released orangutans in the Kehje Sewen Forest and monitor their adaptation. There is always so much going on in the daily lives of both the orangutans and our PRM team and we are delighted to give you an update on some of their news.

Noel

Early morning when the Team had just started activities for the day, they detected Noel’s signal just nearby. Apparently Noel was on the hill adjacent to Camp 103.  Observations commenced at 08.40 and Noel was seen moving from one tree to another, feeding as he went.

After a while, he stopped for a rest and napped until 14.05.  Upon waking, he started feeding once again then moved to the riverbank behind camp. Unfortunately, the Team couldn’t follow him because he moved too fast deep into the forest. See you next time, Noel!

Siwie

The Monitoring Team also observed Siwie eating macaranga.  She looked active and moved from one tree to another. This was the third day in a row the Team recorded her eating macaranga, so we guess now we know one of her favourite foods!

Agus

Agus was found along one of our  monitoring transects. He caused the team some concern as he stayed in his nest all day.

The next day however, he was located on the hill nearby the acclimatisation enclosure. Upon seeing the Team, Agus made kiss-squeak vocalisations, prompting the Team to retreat a little and give him some space. During the day of monitoring, Agus was recorded eating forest fruits and moving through the trees. We are relieved that he is active again. Perhaps he ate something that disagreed with him, which has happened to a couple of orangutans in our Central Kalimantan release program.  We will keep a close eye on him over the coming weeks.

Nila

The Monitoring team met Nila at around 15.02. Nila was seen relaxing in a tree while feeding on forest fruits. The Team observed her for almost two hours and left her at sunset when she was still eating.

Oneng

Oneng was also seen briefly and is one agile orangutan! In the afternoon when the Team reached her location, she was hanging on a tree. She moved around in the trees, sometimes stopping for a quick bite to eat. But quickly moved off into the forest leaving our PRM Team behind.

Kehje Sewen This Week

Miss Popular Wani

Image

Since being released on March 22, Wani who immediately climbed a tree as soon as her travel cage door was opened has been moving around with great agility. She moves from one tree to another trying many different natural wild foods she finds.

Wani has befriended many orangutans and based on our teams observations, Wani has been seen together with Kent, Leke, Berlian, Mona, Noel, and Maduri. Out of these six orangutans, Wani seems to be closer to Berlian and doesn’t appear to enjoy the company of Mona and Kent as much. One time, Hamzah continuously approached her in an attempt to copulate, but she steadfastly refused. Hamzah continued to try several times until night fell, but his efforts were to no avail.

Apart from her courageous efforts in trying new foods, Wani is also starting to feed and travel in taller trees, even those higher than 15 m, and she is also improving her nest building skills.

Kent who Loves to Play in High Trees

Image

Kent usually wakes up at 6 in the morning. Getting out from his nest, he will then move to a nearby tree and start looking for food. So far, he has tried several foods such as various lianas, Diospyrus and ficus shoots. He also loves spending time in high trees. Once, he was seen in a ficus tree higher than 30 meters.

Image

During our latest observations, his radio signal indicated that Kent was nearby a main road by the Soh River. He was indeed sitting in a tree with many lianas intertwined. After waiting for a few hours, the team could no longer see him. Hopefully he will be able to be observed for a longer period next time.

Nila the Wanderer

Image

On a drizzly morning, the Monitoring Team walked towards the Lesik River where Nila was recorded previously. It was already 10.28 but Nila was still in her nest. She climbed out of her nest at 10.32 and it seemed that the cold weather had boosted her appetite. She plucked some nearby fruit and started to eat. Nila has been recorded feeding high up in the trees, and has  only come down to the ground to move to another tree. As the days have gone by, her ranging area is getting larger. According to her radio signal, her range now covers deep into the protected forest and often at times includes the steeper hill areas.

Leke and Bajuri, Stay Together?

Image

Leke was found at 15.05 that particular day, never too far away from that area. She spent the day eating liana fruits she found.  The Monitoring Team also found Bajuri’s signal so maybe they are still hanging out together, as we have reported previously. But since Bajuri’s signal was weak and it was late in the day, the Team decided to observe only Leke. Hopefully they can meet Bajuri during the next observations.
