Circle of Life in Batikap

Death and birth are two certain things for all living beings on earth. It is the circle of life and for every life that sadly passes, a new life is born into the world.

With deep sorrow, the BOS Foundation announces the death of Mogok, a male orangutan who was reintroduced in February 2013, into the Bukit Batikap Conservation Forest. At the same time we would like to share our happiness in welcoming a new baby orangutan who was born in September. The new baby was born to mother, Monic, who was reintroduced on February 28, 2012.

Rest In Peace, Mogok

It is with great sadness that we report the first death of a reintroduced orangutan in Batikap. Mogok passed away on 12 September after a two week battle with sickness as a result of a heavy parasite infection.

Mogok came to us as a two-year old orphan

Mogok spent time in Forest School before moving to Palas Island

Mogok came to us as a two-year old orphan back in 2002, confiscated from a cage where he was kept by a villager. He spent time in Forest School before moving to Palas Island as a seven-year old adolescent, where he learnt how to live on his own in the forest. At the time of his release he was 14 years old and starting to mature into a big adult male. We released him into the Batikap Hill Conservation Forest in February 2013, with a group of other rehabilitated orangutans, and he seemed to be coping well with his new surroundings. He spent a lot of time with Isis, a female released together with him, and we watched him travelling through the canopy and eating a lot of different foods. The last time we followed him, recording data on his daily activities in July he was very well and we were pleased with his progress.

We went to check on Mogok in August as part of our routine observations and data collection on all reintroduced orangutans. Our assistants found him weak and barely active in a fig tree by the side of a river and immediately contacted the monitoring coordinator and vet. They observed him for a day and it was clear he was sick so the decision was made to intervene and bring him back to camp. We didn’t have a transport cage with us, but Mogok clearly knew he needed help and when his name was called he came to us and was carried back to camp in our vets arms.

Mogok had a massive threadworm (Strongyloides) infection. This worm infects both the intestines and lungs and can multiply rapidly. Although we have a full-time experienced vet on site, we reinforced the team with additional veterinary support mobilised from Nyaru Menteng, together with additional medical supplies in the event they were needed. We treated Mogok with repeated doses of antibiotics but Strongyloides can be a fatal illness in orangutans and this case was so developed, he simply couldn’t fight it off. In his weakened state he developed an airsac infection, which complicated matters and required surgery. Although at times he seemed to be improving, and despite the very best efforts of our vets, he passed away after two weeks of intensive 24 hour care.

It is extremely sad to lose an orangutan that we worked so hard to rehabilitate and return to the wild, but we were always realistic from the start that not all of our orangutans would make it – even wild orangutans die in the forest to illness or injuries. We try and give each the best chance possible, and have rigorous standards and procedures in place to ensure we can intervene as and when the need arises, but in the end much of it is up to them. In Mogok’s case the post-mortem results suggest that his illness was natural and perhaps a result of a weak immune-system. We hope that Mogok enjoyed his brief period of freedom after such a short and traumatic life and we continue to work so that his orangutan cousins in Batikap have a better fate as they continue their journey to freedom.

New Generation in Batikap

During the same month that Mogok sadly passed away, the team increased their observations and focus on Monic who was fast approaching her due date. We were somewhat anxious since the Batikap Monitoring Team had reported that since the beginning of 2013, Monic’s transmitter signals had shown that she had been moving further away from Camp Totat Jalu. For the past two or three months her signal was totally untrackable. The Monitoring Team couldn’t help grow more concerned and conducted an intensive search for this young female who was released over eighteen months ago in February 2012.

On September 25, 2013, after one month of intensive searching, the Monitoring Team finally tracked her signal around Ahmat Hill at 10:55 in the morning.  The team directly located Monic who was in the middle of a newly built nest. The team waited for some time until Monic left her nest and when she did, the team could hear the small cries of a baby.

It was an amazing feeling and the team were filled with joy to see what happened right in front of their eyes. Monic came out of the nest carrying a tiny orangutan baby with the umbilical cord still attached. Monica has given birth! The baby looked healthy and cried once in a while. The babies eyes were still shut and his or her tiny hands were holding on tightly to Monic. The Monitoring Team couldn’t indentify the baby’s sex since he or she is constantly  wrapped in Monic’s loving arms.

Post delivery Monic looked healthy and recovered quickly. She didn’t lose her appetite. She ate a variety of foods including banyan fruit, young leaves, rattan shoots, and barks. The new Mum never stopped nursing her baby while eating.

Monic seemed to love her baby so dearly, a few times she was spotted licking and cleaning her child. She was also very protective, making kiss-squeaks to show her displeasure at the Monitoring Teams presence. To avoid  inciting any stress  to Monic, the team observed her for three hours a day.

After the birth on Astrid’s baby, Astro in December 2012, Monic’s baby has added joy to the Batikap forest. Two wild orangutans have been born in their true home.

We will keep updating you with Monic and her baby when we receive more information from the Batikap Team. We hope the new mother and her baby will be blessed with a happy life. Congratulations, Monic, from the big family of the BOS Foundation!

A Full Circle of Life

A circle of life has been completed in Batikap. Mogok has left us and will be sorely missed. But two orangutan babies, children of Astrid and Monic, have graced Batikap with their births. They were born safely and will be ready to explore the forest of Batikap as true wild orangutans. Hopefully, this is a good sign that our wish will come true, to see a new wild orangutan population to thrive in their true habitat.

Update on the stars of ‘Orangutans: The Great Ape Escape’

Almost one year ago, Leonora, Emen and Menteng were part of our first group of ex-captive rehabilitant orangutans to be released into the Bukit Batikap Conservation Forest.  The early steps of their journey were filmed by a film crew for a documentary shown on October 4th on BBC Television in the UK.  So what has happened to these pioneer orangutans since those first few weeks in the forest?  Here is their story so far.

Leonora and Lamar

Leonora was the first rehabilitant to be released.  Once her cage was opened she quickly climbed into the trees with 3 year old infant Lamar on her back.  On the islands Leonora was very inquisitive of people and had formed bonds with several of her technicians. Yet once in the forest Leonora was content to stay in the trees and explore her new surroundings, she seemed no longer bothered by people.  But as the weeks went on she seemed to enjoy the presence of people, often following the observers rather than the other way around.  She even came to the ground once to examine a hammock that had just been put up by one of the monitoring team.  She skilfully untied it before going on her way.  Perhaps she was a bit lonely, perhaps she still expected people to give her food like before on the islands – an expectation that must be getting less by the month.

After four months she was already eating lots of different kinds of food, the inner pith of rattan climbers, the sweet inner bark of leguminous trees, termites sucked out of rotten logs.  She had never needed to eat these foods on Kaja island, because she was given enough fruit and vegetables there to keep her well-fed, and yet she had explored and tried everything on the island.  An orangutan’s inquisitive nature gives them a good chance of survival in the wild.  And here she was four months later teaching her young son how to access these fallback foods that will be needed when fruit stocks become low in the dry season.

She didn’t eat everything, however, indeed one of the best fruits, wild durian, is encased in a spiny shell and Leonora seemed unsure how to get inside it.  She resorted to picking up the cracked-open fruits from the forest floor instead!

After six months Leonora had lost a little excess weight, but was still healthy, and her hair had thinned – probably because long hair gets torn out in the dense and spiny rainforest.  Lamar meanwhile had become very independent, rarely suckling, moving freely and always quick to shake branches and kiss-squeak at the monitoring team if they come too close.  It is great to see that the infants of the tame adults are keeping their wild nature.  He has even thrown branches on occasion! At three and a half years old Lamar is trying out lots of fruits and has started practising making his own nests.  Sometimes these are very good, but he always sleeps with his mother.

Now one year on, Leonora and Lamar rarely seem to notice the monitoring team.  We only see them once a month now, whilst we focus on the new arrivals, and they are very content in the forest.  They are still learning, especially Lamar, but there are now plenty of other orangutans living near them to share experiences and knowledge with. We are delighted by the progress they have made.

Emen and Embong

Emen was released fourth on that November day almost one year ago.  Emen was a little older and slower than Leonora, and she had lost four fingers on her right hand making it harder for her to move around the forest.  She was perhaps not as ready for the sharp transition from island life to the vast jungle and this showed during her first month.  She started off by following Leonora around, and when Leonora wanted some space she stayed on her own, not moving too far.  After 10 days we found her lying ill on the ground, and the next day she climbed high into a tree where she stayed for the next three days.  As shown on the BBC documentary, we decided to intervene and send her some food on a pulley, to make sure her son Embong wasn’t becoming malnourished.  Although an adult orangutan can go many days without food, we were much more concerned about the infant.  Three days after the food supply, Emen left the tree and we saw her eating wild fruits again.  We think that she had eaten something a little poisonous, perhaps a wild nutmeg or some other fruit that doesn’t occur on Kaja island.  This trial and error method of learning about their new environment is going to be inevitable for all our orangutans.

Emen & Embong

Over the next few weeks it was Embong who seemed to take the lead and choose which trees to visit, maybe he was simply enthusiastic and didn’t want to wait for his slow mum!  Yet despite her handicap Emen has proved very capable in the wild, even using her body as a bridge to help Embong cross gaps.

Five months after her release Emen was still reacting to the sound of boats on the river, an inevitable link to her ten years on Kaja island where the sound of boats usually meant the arrival of food.  Emen has never travelled too far from the large Joloi river, even crossing it occasionally. During June and July she was frequently found on the opposite side of the river with Ebol, a young female rescued from the wild and released four months before Emen.  Forming good social bonds with their neighbours is vitally important for the well-being of the released orangutans.

Now one year on Emen and Embong are living quite independently.  They are starting to ignore and not care about the presence of human observers. They have gained a good understanding of their forest and travel routes, with special places to cross the river locked in their memory.  They are smart enough to find many kinds of fruit, and if that is diminished Emen can also switch her focus to find and eat the leaves and pith from lianas and trees.  Embong is very active and with the affection of his mother is learning about the forest and how to make a nest.  Like Lamar he is wild and energetic.  Hopefully Emen and Embong will be content in their new habitat forever.

Menteng

Menteng was the largest male released in this group.  Formerly a timid young orangutan on Kaja island, he was starting to develop his large cheek pads and grow into full adult size by the time of his release.  We had a lot of difficulties with Menteng at the start, as whenever we came near he descended and followed us.  Perhaps he was lonely, perhaps he just wanted to see where we were going, or more likely he wanted to search our bags for fruit! – but this made us cautious as a large tame adult male orangutan can be unpredictable and they are very strong.  So we always retreated and eventually moved into the boats.

Menteng continued this behaviour for the next four months.  He stayed close to the river and found a way to cross, so we were never sure which bank to moor up on.  We tried to keep monitoring him, although it was impossible on foot – so we don’t really know what he was eating or doing when we weren’t there.  On several occasions he chased our team into their boats.  Then we saw him with a new, shallow scar on his cheekpad, a sign he had been in a fight with another male, perhaps Tarzan who is dominant in the area near our camp.

About six months ago, things changed a little, and we could occasionally follow him.  Then the next day he would become aggressive again – we think he had chosen his favourites from the monitoring team!  But after May his radio-signal was picked up less often, a sign he had started to explore further away from the river, and since July we haven’t picked up his signal at all.  We don’t know where he has been during these two months, but hope he is happy exploring his forest home as he continues to mature.  Adult males travel very long distances and often return only months later.  We will keep tabs on where Menteng has decided to settle.

The other eight orangutans released at the same time – Sif and her daughter Sifa, Gadis and her daughter Garu, Chanel and her son Charlie, Jamiat and Terusan – are also occasionally followed to check how they are doing.  All are fine, some like Terusan have travelled far, others like Sif are still near their release point.  We are delighted with all their progress, and will keep you updated as we find out news.
