A More Independent Sayang

April 24, 2015. Posted in Article

A few days ago, in the early afternoon, we spotted movements in the top of a tree near Camp Lesik.  As we approached, we found that it was Yayang’s daughter, Sayang.

Seeing her busy eating fruits, we tried to locate Yayang who we expected to be somewhere nearby. However, our telemetry equipment detected no signal, which means Sayang was on her own and is making great strides at becoming an independent orangutan. Great news!

We decided to follow her. She was busy moving from tree to tree and seemed to be quite aware that we were watching. She often displayed her displeasure by throwing twigs at us and kiss-squeaking, then she quickly moved again as if in an attempt to lose us.

That day, she spent most of her time traveling through the trees and exploring Kehje Sewen. She also ate a lot of fruit and young shoots. As the day drew to a close, Sayang climbed into her nest to sleep and we headed back to Camp Lesik.


The day after, before sunrise, we departed to conduct Sayang’s first nest-to-nest observation without her mother. When we reached her nesting location, she was still asleep, so we patiently waiting and quietly ate our breakfast.

Not long after, Sayang woke up. She climbed out of her nest and started to quickly travel through the trees. Keeping our distance, we picked up our pace to follow her. Not long after, we heard a long call. Sayang stopped for a moment to observe her surroundings.

Sayang’s activities were similar to her activities the day before – she was keenly exploring Kehje Sewen Forest and ate plenty of forest fruits. We are very happy to witness Sayang’s independence and see that she is thriving in her true home.

We can help save the environment in a lot of ways, and one of those is to save orangutan from extinction. The more orangutans living in their natural habitat, the more forest, environment, and humans can be saved, too. Help us to keep on protecting the forest and orangutans. Donate now!

Span, Favourite Hangout Spot in Kehje Sewen

April 17, 2015. Posted in Article

When we talk about forest, we would also discuss about its various functions: the habitat for millions of flora and fauna, source of oxygen for every living creatures, and more others which make the forest and everything within an inter-twisting unity and endless discussion.

In the RHOI-managed Kehje Sewen forest, there is a favourite site for all the animals. It is called   mineral lick or locally known as span.

Span is a spot in the forest where animals obtain important mineral nutritions from a deposit containing elements such as natrium, calsium, iron, phosphorus, and other important ones that they need to develop and grow their bones and muscles. Wild herbivore mammals and birds would regularly visit this span. Span is a significant part of this ecosystem, providing alternative nutrition for all living animals in the area.

Several weeks ago, we did some monitoring in the area and we encountered a lot of wild animals there. There were mammals, birds, and serpents gathering in the span area. Not wanting to miss the opportunity, we decided to take a peek from behind the bushes and see the activities took place.

Maroon Leaf Monkey (Presbytis Rubicunda)

Bengal Monitor (Varanus bengalensis)

Sumtran Viper Snake

Having witnessed the variety of life found in Kehje Sewen forest, we are confidence that there are still plenty of forest areas in Kalimantan and other parts of Indonesia left that we can protect and preserve.

The Look of Casey, Lesan, Hamzah, and Mona

April 9, 2015. Posted in Article

This week we encountered four released orangutans in Kehje Sewen. They are Casey, Lesan, Hamzah, and Mona. How happy we feel for having the opportunity of bumping into memorable glances.

Casey, Lesan, and Hamzah were sitting around on an open area near Camp Lesik. It was getting dark and we were just back from our daily monitoring trip at Gunung Belah transect. These three orangutans looked so close to each other and did not seem to be entirely bothered by us coming back to the camp.

They gave us a deep glance.

A couple days later, we went to monitor the area of Lembu transect. As usual we started our activities early, and set out to Lembu transect for daily monitoring. We reached the transect at exactly 2 PM and we built a flying camp there. That was when we heard rustles above our heads.

It turned out to be Mona. She was observing us high above a tree. She gave us a deep glance.

When the sun started to set in, Mona slowly moves away from the flying camp and went deeper into the forest.

Until today, Casey, Lesan, Hamzah, and Mona are in a very good health condition and we all feel very pleased to be able to observe them in their habitat.

Keep on supporting us in monitoring  the lives of wild orangutans in Kehje Sewen forest. DONATE NOW!
