Orangutan Stories: Sheila

This month we received one of the best possible messages from our field team- another orangutan has been born in the wild! This exciting new addition makes it an astonishing nine newborns over the past 12 months in the Lamandau Wildlife Reserve. In over 30 years of work in the field, we cannot remember an orangutan baby-boom as flourishing as this!

At the beginning of this month, our field team at Camp Gemini noticed that they hadn’t seen Sheila for a while, this behaviour was unusual as she has established herself as an almost daily visitor at camp. That was until the morning of Saturday 5th June when Sheila emerged from the forest and proudly presented her new infant to our team.

Unlike other great apes, orangutans on average give birth three or four times in their lifetime. This welcome latest arrival will add to Sheila’s experience as a mother having already successfully raised 13-year-old female Sakura and 6-year-old male Sony- both of whom are still regularly observed in and around Camp Gemini.

Sheila has been a wonderful teacher to the pair and although they have both shown that they can be independent in the forest, it’s not uncommon to see all three feeding together occasionally. Being the younger of the pair, Sony in particular is known to follow Sheila from tree to tree, but the introduction of a new sibling is likely to give him that needed push to explore the forest on his own more.

The early weeks of a newborn’s life are their most vulnerable which is why since Sheila gave birth to her newest infant, our team have kept a watchful eye on the pair and are pleased to see that they are progressing well. Like Ilik’s recent newborn at Camp Gemini, it’s thought that the sex of Sheila’s new arrival is male and as it’s likely he was born on World Environment Day, he has appropriately been named Silva- a term for integrated forest management.

We believe habitat protection is the key to ensure a safe environment for orangutans and all wildlife. Therefore conserving the Lamandau Wildlife Reserve safeguards it from illegal activity and habitat loss. Without this vital protection, would we have been able to record over 90 orangutan births in the Reserve? We look forward to seeing this new viable population of critically endangered orangutans and further generations.

Orangutan Stories: Acuy

Ex-captive orangutan Acuy was introduced to the Lamandau Wildlife Reserve around 15 years ago and has left a lasting legacy by becoming a grandmother:

2006- As a nine-year-old, Acuy was introduced into the protected forest and quickly established herself as a regular with our field team. She seemed to be as confident interacting with other wild orangutans as she was seeing our staff on her visits to Camp Rasak.

2007- A year after being released into the Reserve, Acuy gave birth to her first offspring, Amina. Like most orangutan mothers, the bond between Acuy and her infant was very strong and Amina soon learnt the ways of the forest by watching her mother climb, build a nest, and search for fruiting trees.

2015- Acuy was an excellent teacher, and Amina mastered the essential forest skills to become fully independent, paving the way for Acuy to raise another infant- Ariel. It’s always good news to welcome an orangutan’s second offspring, and our staff were confident that Acuy’s mothering instincts would be as strong for Ariel as they were for Amina.

2019- Our field team were delighted when they discovered that Amina was seen to be pregnant, and waited with anticipation for her to give birth to her first infant, Albie. To observe four orangutans across three generations is a true testament to Acuy’s successful transition from ex-captive to a grandmother, and we were thrilled to see her family continue to grow.

Both of Acuy’s births happened a stone’s throw away from Camp Rasak, and her familiarity with camp and our team has given us a genuine insight into the natural behaviour and relationship between her and her offspring. During regular monitoring in the field, a member of our team noticed that two of Acuy’s left toes were badly injured- perhaps from an altercation with another orangutan or wild boar. Left untreated, the wound could have been at risk of infection, so for Acuy’s safety, our vet was called in.

With Ariel by her side, Acuy spent the next two weeks at camp being cared for by our team. Ensuring that she received antibiotics and regular antiseptic treatment, our field team were soon able to see that the wound had healed and therefore released Acuy and Ariel back into the forest where they belong.

Through our work in the Lamandau Wildlife Reserve, we try and intervene with wild and reintroduced orangutans as little as possible to allow their natural behaviour to develop organically. Occasionally instances do arise when our monitoring and veterinary teams must reach out a helping hand, but as with Acuy, this would not be at all possible were it not for the placid nature and demeanour of this gentle great ape.

Orangutan Stories: Ilik

This month our field team are delighted to announce the exciting news that wild female orangutan Ilik has successfully given birth!

Ilik’s exact age is unknown as she was translocated to the Lamandau Wildlife Reserve in 2007. It would be fair to say that she feels safe this protected habitat, without the threat of habitat encroachment, as her latest arrival is now her second infant in the forest.

In May 2016, our team were over the moon to see that Ilik had settled into her surroundings and had given birth to her first offspring- a female named Izzy. Tragically however, after a couple of years, Ilik was found carrying the lifeless body of Izzy. It was sad for us to see Ilik not wanting to give up her dead infant. She continued to carry the body around in the trees for a few days until she was ready to let go.

There are many potential hazards which could endanger the life of a young wild orangutan such as pythons, leopards, and wild boars; but Izzy’s death appeared to be inexplicable to our staff. Following a detailed necropsy there appeared to be no wounds or damage to Izzy’s internal organs, so the cause of death for Ilik’s first infant remains unknown. An unfortunate yet heart-breaking quirk of nature perhaps.

Ilik%2B1.jpg

Knowing Ilik’s history, we were even more thrilled to see that this month she has given birth again in the Reserve. Our team at Camp Gemini noticed recently that Ilik ventured deep into the forest away from camp, only to return four days later with an infant holding on tightly. The first recorded birth of 2021 and eighth born in the Reserve in the past 12 months!

Despite Ilik losing her first born, we are confident that this experience will hold her in good stead to care for her newest arrival. In the meantime, it’s heart-warming to see that the pair seem happy climbing in the trees around camp. Currently Ilik is being followed by a member of our field team who has reported back that both are looking well and the infant is still so tiny that we cannot yet identify the sex.

Orangutan Stories: Brian

One might think that when an orangutan is rescued and released into the wild- it’s plain sailing from thereon in. For inexperienced orangutans like Brian however, it can take a while to find your feet in the challenging life of the forest.

Brian was originally rescued from an oil palm plantation. The whereabouts of his mother are unknown.

Brian was originally rescued as a pet. The whereabouts of his mother are unknown.

In 2009, after quarantine Brian was brought to Camp Gemini in the Lamandau Wildlife Reserve by government officials (BKSDA) so that he would have the opportunity to integrate into the surrounding orangutan population. At three years old and without his mother to learn from, Brian needed a role-model to help him adapt to this new environment. Fortunately, female orangutan Rosa did not have an infant of her own at the time and showed compassion in taking Brian under her wing. Together they formed a strong pair, and from his surrogate mother Brian was taught the basic forest skills required to survive in the forest.

After two years, Rosa gave birth to an infant of her own and began venturing into the forest without Brian in tow. He may have been jealous of Rosa’s new arrival, but it was the push Brian needed to roam the forest independently and become confident in the trees. It wasn’t long until he crossed paths with a larger wild orangutan named Bangkal who has been the dominant male in this area of the Reserve for many years. To his credit Brian did not back down, but following a confrontation with Bangkal, our field team decided that it would be beneficial for Brian to be translocated elsewhere in the forest for his own safety.

Wild male orangutans cover large areas, sometimes hundreds of acres of habitat as they search for a mate or fruiting tree. It’s therefore quite common for their ranges to overlap with other males, leading to quarrels from time to time.

After his relocation to Camp Buluh, Brian was sadly involved in another fracas with a wild male in 2019. Not learning his lesson from his previous encounter, Brian perhaps acted more bravely than he should have and had an unfortunate run-in with wild male Yoko. During this clash Brian suffered severe injuries to his head, body, and arms, resulting in him requiring some emergency treatment and minor surgery from our vet. Despite the slight dent in confidence, with some time to lick his wounds Brian soon made a full recovery and was able to get back in the trees where he belongs.

Our team decided that another relocation to Camp JL would be the best fit for Brian’s return to the forest as there would be fewer competition with dominant males. Now Brian has adapted to this new area of the forest and seems to happily swing in the trees around camp and across the river. His story shows how challenging life in the forest can be for orangutans that are still learning, and also how resilient this critically endangered great ape can be.

Brian has overcome many challenges and is now thriving at Camp JL

Orangutan Stories: Bumi

In June 2017, local government officials from BKSDA informed the Foundation that a young male orangutan had been kept as a pet in a cage and confiscated from a nearby village. Entrusted into the care of the Orangutan Foundation, our veterinary team quickly examined the infant, named Bumi, who was estimated to be around three and a half years old.

Under inspection it was discovered that Bumi, a name that in English means ‘Earth’, tragically had gun pellets lodged in his skin. It’s uncertain how Bumi received these injuries, but likely that he had been shot during his separation from his mother. Fortunately, our expert team where able to remove seven gun pellets from Bumi’s body (as seen below), and he successfully entered into the Foundation’s soft-release programme for orphaned orangutans in the Lamandau Wildlife Reserve.

Alongside Endut and Satria at Camp Rasak, in the soft-release programme Bumi has been able to practice pivotal skills such as nest-building, climbing, and searching for food in the natural environment of the forest. A fast learner, Bumi quickly began showcasing his nest-building ability from a young age in his enclosure.

Bumi’s progress from when he first arrived has developed remarkably well. Now at around seven years of age he is growing into a strong young male orangutan, confident climbing and searching for food in the trees, and capable of building large sturdy nests.

Under the close watch of our field team, Bumi has even been able to stay out overnight to become more habituated to forest conditions. Not all conditions however, as when it rains Bumi will often run back to shelter in the safety of camp. Once truly independent, he will be ready to be released.

bumi+%28bawah%29+dan+satria+Nov+17.jpg

Following his latest medical check-up, Bumi was given the all-clear for potential illnesses such as Hepatitis, and received supplementary vitamins to help him stay healthy. With this clean bill of health it could be only a matter of time until Bumi will be released into the forest. This is a tremendous achievement for this spirited young orangutan, especially taking into account his difficult early life as a pet.

Orangutan Stories: Nyunyu

One of five orphaned orangutans at Camp JL within the Lamandau Wildlife Reserve, Nyunyu has progressed tremendously since her introduction to the Foundation’s soft-release programme in 2017.

At around 3½ years old, Nyunyu was discovered being kept as a pet before being handed over to our team in the town of Sampit, Central Kalimantan, Indonesian Borneo. Without a mother to learn from, entering a programme to learn and develop essential forest skills was critical for Nyunyu so that she could have the best possible chance of a successful future in the wild.

Our team transport Boy (left), Mona (middle), and Nyunyu (right) from their overnight enclosures into the forest.

Our team transport Boy (left), Mona (middle), and Nyunyu (right) from their overnight enclosures into the forest.

Today, Nyunyu shares Camp JL with fellow orangutans Boy, Mona, Timtom, and Adib. These young primates are regularly brought into the forest by our assistants to practice skills such as climbing, nest-building, and foraging for food.

Our teams frequently observe Nyunyu eating bark, fruits, and ants in the trees, but had never seen her building a nest- until now. Recently we spotted her bending tree branches and eating the young leaves, as per usual, however she then began arranging the vegetation into the shape of a nest for the very first time. A breakthrough moment for the learning great ape!

As it was Nyunyu’s first ever attempt at building a nest, it is fair to say that it was not as strong as it could be. Nevertheless, this is a wonderful sign that Nyunyu’s forest skills are developing and she’s continuing to grow in confidence.

Initially she was only content testing her abilities in the trees around camp, but now Nyunyu is capable of going deeper into the forest to climb and explore new areas of habitat.

Initially she was only content testing her abilities in the trees around camp, but now Nyunyu is capable of going deeper into the forest to climb and explore new areas of habitat.

Will practice make perfect for Nyunyu’s nest-building ability? Only time will tell, but our team will continue to monitor her progress and are very pleased with the growth she has made thus far. We are hopeful that Nyunyu has the potential to join the many orangutan graduates of the soft-release programme and be released into the Reserve one day.

It’s never easy for a young primate to adjust from a life in a cage to one in the forest, but Nyunyu is a prime example of a rescued orangutan on the right path to a successful independent future in the wild.

Even 2020 can be an Inspiration

We didn’t expect our recap of 2020 to be quite like this.

Last year we were looking forward to celebrating the Foundation’s 30th anniversary, however life had other plans for all of us. COVID-19 impacted the lives of everyone both in the UK and in Indonesia, which meant we had to adapt. To commemorate our anniversary, we published a booklet ‘Orangutan Foundation - 30 Years of Conservation’.

There were many things to inspire us in 2020, including the progress of orphaned orangutans like adventurous Okto (above) in our soft-release programme.

There were many things to inspire us in 2020, including the progress of orphaned orangutans like adventurous Okto (above) in our soft-release programme.

Orangutans share around 97% of their DNA with humans, which means COVID-19 poses a potential threat to this critically endangered species. Fortunately however, none of the orangutans we monitor, or any of our 60 local staff have been taken ill by the virus. In fact if a small silver lining can be drawn from this difficult situation, it is that working and communicating remotely where possible has meant that everyone has learnt how to embrace the use of new technology, Zoom!

Community outreach and education is one of the fundamental cornerstones of the Foundation’s work. Therefore during lockdown, our team had to find new ways of working together remotely.

Conservation Corner, before and during the pandemic. This is a platform where local youth groups, students, researchers, and members of the conservation community can meet to exchange concepts and ideas. One online session had close to 100 people joining in, demonstrating the concern that younger members of the community have for the environment.

Local events are vital to keep raising awareness and promote habitat protection, and luckily before restrictions last year, we were able to hold a number of community activities. Including:

Our Forest Restoration Programme was active throughout the year. Our team planted an additional 16,500 young trees in areas which one day will bolster existing forest boundaries.

By cultivating saplings in specially designed nurseries and then planting them along existing forest boundaries, we can turn previously destroyed habitat into rainforest of the future.

Much like us, in 2020 the forest also faced a new challenge. The rainforests of Central Kalimantan in Indonesian Borneo suffered some of the most severe flooding in recent memory, submerging large areas of habitat for much of the year. This is a stark contrast to previous years which would have been battling forest fires during the dry season. A striking reminder of how unpredictable our weather patterns have become as the impacts of climate change take hold.

The unpredictable nature of climate change. In September 2019 our guard post teams were fighting forest fires, and 12 months later their outposts are submerged by flooding.

Unsurprisingly, it was the orangutans that gave us the best news and most amusing stories last year. The orphaned orangutans in our soft-release programme for example continued to go from strength to strength as they develop new forest skills, with Okto in particular, impatient for an independent life in the wild.

In June, we were very excited to discover that wild orangutan Pauline had given birth in the Lamandau Wildlife Reserve. Then shortly after, our field team were surprised again when Queen showed off her infant. Two recorded births of these great apes in such a short space of time is unusual, so to have observed a remarkable seven orangutan arrivals by the end of November was truly astonishing! It’s an extremely rare occurrence to have so many recorded births in less than 6 months, but a welcome boost for the future of this critically endangered species.

We were truly blown away by your support in 2020, in spite of restrictions. In particular for our 30th Anniversary Appeal which launched last year in collaboration with SOCP (The Sumatran Orangutan Conservation Programme), helping save all three species of orangutan.

2020 will be remembered for many reasons, but perhaps more than any other year, it must be remembered for the connection we have made between the welfare of our planet and the importance of nature. By continuing to save our forests, we can mitigate the impacts of climate change.

We have been inspired and overwhelmed by the generosity we received in 2020, even through these difficult times. We sincerely appreciate the devotion of all partners, fundraisers, and supporters on Orangutan Foundation’s 30th anniversary year, and look forward to keep making a difference in the years to come.

Orangutan Stories: Betli

This month we focus our attention on orangutan mother Betli; a well-known face to our field staff in the Lamandau Wildlife Reserve, Indonesian Borneo.

This tropical forest is home to around 600 critically endangered orangutans, roughly half of which are reintroduced having been ex-captive or rescued. From our forest camps we monitor as many of these great apes as possible to ensure that the population remains healthy, and our team recently observed that Betli has wonderfully added one more precious infant to the growing number of orangutans in the Reserve.

Betli and her new baby take a rest on the forest floor.

Betli and her new baby take a rest on the forest floor.

As an entirely wild orangutan her exact age is unknown, but it’s thought that Betli was around 7 years of age when first sighted by our field team at Camp Buluh in 2009. Since then she has gone on to care for three other infants, with her newest arrival her fourth offspring.

Berlane is Betli’s oldest son, and is still observed from time to time foraging in the forest.

Berlane is Betli’s oldest son, and is still observed from time to time foraging in the forest.

Like many new orangutan mother’s, Betli is protective of her baby. This means that although some magnificent photos have been taken of the pair, our team haven’t yet been able to identify the sex of the infant. Most importantly Betli and her young appear healthy and we look forward to keeping an eye on their progress in the forest.

Following Betli’s and Passion’s latest arrivals, it appears we will end 2020 having recorded an astonishing seven orangutan births in just 12 months. This number of orangutan arrivals in such a short space of time has never been witnessed before by our team, and emphasizes how important this protected habitat is for the future of this critically endangered species.

Bursting with life - Mammals

Despite covering around 6% of Earth’s land surface, it’s estimated that tropical rainforests are home to 80% of our planet’s terrestrial biodiversity. These diverse forests are truly bursting with life, and within Tanjung Puting National Park and the Lamandau Wildlife Reserve in Indonesian Borneo, there are prime examples of this rich habitat.

During their work in the forest, our field teams spot orangutans and other primates in the trees, and yet they rarely see other Mammals as many tend to venture out at night. The elusiveness of many mammalian species in the forest means that the only time our team observe them is on remote camera traps or during wildlife rescues. Some of these fascinating species include:

Sunda Clouded Leopard - Neofelis diardi - Like orangutans, this species of leopard is native to the tropical forests of Borneo and Sumatra. Very little is known about the behaviour of these nocturnal and predatory cats due to their elusive nature, however we do know that their canine teeth are longer than any other cat species in relation to their body size, and their long tail helps with balance as they navigate through the tree tops and forest floor.

The main threat to these iconic forest cats is habitat loss; another trait shared with orangutans. Listed as 'Vulnerable' on the IUCN Red List, there are only an estimated 4,500 individuals remaining in the wild.

Sun Bear - Helarctos malayanus - This is the only bear found in South East Asia and the smallest of all the 8 bear species. Their smaller size means that they are perfectly suited to an arboreal life and their long claws and tongue are ideal for feeding on insects and honey in the trees.

The name ‘Sun Bear’ comes from the pale patch of fur on their chests which is said to resemble a rising or setting sun. Each pattern is unique like a human fingerprint, helping to distinguish one individual from another.

Malayan Civet - Viverra tangalunga - These small omnivorous mammals roam its forest habitat at night in the search for fruit, insects, and anything else it can find to eat. Although largely solitary, it's thought that civets use scent as a way of remotely communicating with one another amongst the dense vegetation by rubbing themselves on trees and the leaves on the forest floor.

civet.png

Asian Small-clawed Otter - Aonyx cinereus - Rarely observed in the forest’s network of rivers as they tend to search for their food at night, these otters have extremely dexterous hands which are ideal at finding shellfish and crustaceans underwater. Through their high-pitched squeaks the otters can accurately locate one another, and it’s suggested that they can communicate using 12 or more different social calls. These are the smallest of all 13 otter species, but habitat loss and water pollution has impacted their numbers to the extent that they are classified as a species that is ‘Vulnerable’.

Otter.jpg

Yellow-throated Marten - Martes flavigula - Martens are members of the Mustelidae family (like weasels, ferrets, and badgers), and feast on a variety of food from lizards and bird eggs to fruit and nectar- thought to make them important seed dispersers in the forest. The yellow-throated marten is found throughout wooded areas of South East Asia, and their muscly build and long tail help make them as agile in the canopy as they are on the forest floor.

Kamera%2Btrap%2B-%2BMusang%2Bleher%2Bkuning.jpg

Malayan Porcupine - Hystrix brachyura - This is the largest of the seven porcupine species found in Asia. This species rely on their burrows to stay in during the day, and come out at night to forage for roots, seeds, nuts, and fallen fruit. Malayan porcupines appear to have strong family ties and will often travel in small groups searching for food. They may have few predators in this habitat, but when threatened, porcupines will often charge backwards in the hope that their sharp quills will deter any aggressor.

porcupine.png

Bornean Bearded Pig - Sus barbatus - Like other pig species, the Bornean Bearded Pig is omnivorous and will feed on a variety of forest foods. Their long snouts are perfectly evolved to search for worms and tree roots under the soil, and they will also forage for seeds and fruit dropped by animals high up in the canopy. These pigs reach sexual maturity at around 18 months old and usually give birth to between two and four offspring at a time. Piglets have stripy coats to help them camouflage into their surroundings which fade in later life.

Kamera+Trap_Babi+hutan.jpg

Deer - There are a variety of deer found in Borneo, the most commonly observed by our staff are muntjac or barking deer (below centre). With no wild tigers on this tropical island, and clouded leopards and humans being their only predators, deer can thrive in the forest feeding on vegetation. Lesser Mouse Deer (Tragulus kanchil, below left) and the vulnerable Sambar Deer (Rusa unicolor, below right) can also be found in another environment where the Foundation operates in Central Kalimantan, the Belantikan region.

Orangutan Stories: Maya

This week, wild orangutan Macho will be 6 years old and his mother Maya has given him an extra special birthday gift- a new sibling to play with!

Astonishingly, Maya’s new infant will be the sixth orangutan birth recorded in 2020 in the Lamandau Wildlife Reserve, just a couple of weeks after we shared the news of Betli’s latest arrival. Considering that female orangutans will generally have a maximum of three or four offspring in their lifetime as they care for their young for several years, it puts into perspective how fruitful this year has been for the orangutans of this Reserve.

23-year-old Maya’s newest arrival will be her third infant following her son Mozart who was born in 2008 and her second son Macho. Although learning to be independent, Macho still never seems to stray too far away from his mother, and the pair are occasionally observed together searching for food in the forest near Camp Gemini.

Maya was photographed in September showing signs of pregnancy

Our monitoring staff at camp were thrilled this week to learn that Macho had received a new brother or sister. On Monday afternoon our team spotted Maya and Macho as normal, but under closer inspection it was evident that there was a new face buried into the hair on Maya’s back.

Naturally being protective of her young infant, Maya has kept her newborn close in their precious first days together, so much so that our team are yet to get a clear photograph of the young primate. It’s thought that the newborn is female, making her Maya’s first daughter, but more observations are required before we can begin to definitively identify the sex and give a name to the infant.

Most importantly, these critically endangered orangutans appear to be healthy and doing very well in this natural habitat. We’re confident that Maya will be as caring a mother to her newborn as she has been to Macho and we look forward to studying their relationship as it grows together.

Great apes in print

We have been working with outstanding wildlife photographer Ian Wood to raise awareness of orangutans and showcase some of Ian's wonderful photographic prints.

For the unique opportunity to obtain a limited edition, high-quality orangutan print, join the online auction here for your chance to bid on a one-off print signed by our Founder & Director/Trustee, Ashley Leiman OBE. You can also visit the Lucy Bell Gallery in St Leonard’s-on Sea before the 14th November to see this amazing work in person!

Additionally, there are five incredible prints available online with 25% of all proceeds going to the Orangutan Foundation. Each print has their own story from Ian:

Photo 1 - Wise man of the forest
A close encounter with this wild male Borneo orangutan in Lamandau wildlife reserve, Kalimantan, Indonesia. This area of forest offers real hope for the future and is where the Orangutan Foundation’s forest regeneration program takes place with tens of 1000s of new trees planted.

Photo 2 - The kiss
Orangutans are the best mothers in the natural world with their offspring dependent on them for up to eight years. I captured this moment in Tanjung Puting National Park,Borneo, which shows the love between mum and baby is very mutual.

Photo 3 - Gentle giant
I was fascinated with this male orangutan’s interaction with a butterfly which I hope captures the gentle nature of these animals. Taken in Tanjung Puting National Park, Borneo.

Photo 4 -The windows to the soul
I love being in a storm in the rain forest and this was taken after a downpour of biblical proportions. Crouching under a tarpaulin to keep my camera gear dry, I waited for the deluge to end and was rewarded with such a close encounter with this curious baby orangutan.


Photo 5 - Joy
Observing young orangutans is often an experience full of joy and the expression on this one’s face sums up this enchanting spirit they have. Taken in Tanjung Puting National Park, Borneo.

Bursting with life - Birds

The diverse ecosystems within Tanjung Puting National Park and the Lamandau Wildlife Reserve in Indonesian Borneo are truly bursting with life. Our staff are fortunate to come across a variety of interesting species as they monitor orangutans in the field, conduct research, and safeguard the forest. Some of the most eye-catching species we come across are Birds, including:

Hornbills - There are 8 species of hornbill found in Borneo, and they are perhaps the most iconic birds found in the forests of this tropical island. Hornbills are infamous for the large casques on their beaks, the most eye-catching of which is the Rhinoceros Hornbill, Buceros rhinoceros. These impressive birds have brightly coloured beaks, can have a 50-inch wingspan, and typically mate for life.

Crested Serpent Eagle - Spilornis cheela - These raptors are found in various forest types and can survive in areas of disturbed habitat where other birds may not. In fact it could be said that these eagles prefer forest edges, where they can hunt for a variety of prey from snakes and lizards to small mammals and fish. This adaptability helps make them such a successful raptor species and they can also be found as far as India and the Philippines.

SRPA+-+Elang-ular+bido.jpg

Asian Paradise Flycatcher - Terpsiphone paradisi - By looking at them, you could be forgiven for thinking that the male and female Asian Paradise Flycatcher are birds of completely different species, such is the contrast in their appearance. Females are modest-looking with black feathers on their heads and brown bodies, whereas adult males have bright white plumage and two enormous tail streamers. It’s thought these feathers are elongated to attract a mate and can grow up to 12 inches- longer than their entire body!

Storm's Stork - Ciconia stormi - This is sadly a species in decline and thought to be the rarest of all storks. Due to the loss of habitat in this part of the world, Storm’s Storks are listed as endangered on the IUCN Red List with fewer than 500 individuals remaining in the wild. These forests in Indonesian Borneo are a real stronghold for this vulnerable species so sightings of breeding pairs are vitally important.

SRPA+-+Sendang+lawe+%281%29.jpg

Kingfishers - The easiest way for our field teams to navigate through the forest is via the network of rivers, an ideal habitat for kingfishers. The Stork-billed and Blue-eared Kingfisher (Pelargopsis capensis & Alcedo meninting) are the most commonly seen species in these forests. Stork-billed are perhaps the most striking as they have large red bills and an explosive alarm call which is then followed by an unusual cack-cack-cack-cack laugh!

This is just a selection of the hundreds of bird species found in this diverse tropical forest environment. By supporting our guard posts and habitat restoration programme, your help is ensuring that these important species continue to live in a haven which is protected.

Orangutan Stories: Aan

Rescues are an essential pillar of our work as they save orangutans in need. The majority of rescues take place in oil-palm plantations or community land where orangutans can become stranded and unable to find suitable forest habitat in which to survive.

After medical check-ups, most adult rescued orangutans are able to be swiftly released back into a natural habitat that is protected such as the Lamandau Wildlife Reserve. However due to the injuries inflicted on female orangutan Aan, she is an unfortunate exception to this rule.

Aan+%281%29.jpg

On her rescue from an oil-palm plantation in 2012, our team discovered that Aan’s left eyeball was missing entirely and under initial inspection, it was clear that she was malnourished and that her body was peppered with wounds from air rifle pellets. It was estimated that there were around 12 pellets visible in her skin but an X-ray would be required to find out the true extent of her injuries.

Incredibly it was revealed that Aan had in fact been shot over 100 times; 67 times on her arms, legs, and torso, and 37 on her head. It was truly remarkable that she was still alive.

Following a successful operation (below), 30 rifle pellets were safely removed from around Aan’s face whilst the remaining bullets were too deep under the skin and not doing any harm. She was then transported to the Lamandau Wildlife Reserve where she could recover and gather her strength.

It soon became apparent that Aan’s right eye was also not responsive, and unless this sight could be restored, she would never be able to be released back into the wild for her own safety.

A ray of hope came in 2017 when a group of vets from the UK travelled to Borneo to operate on Aan’s remaining eye (below). At first there was cautious optimism as Aan’s cataract was removed and her optic nerve was still intact, however once she had come round from the anaesthetic, it appeared that unfortunately the damage she had previously sustained was too much.

Aan is now around 20 years old. In the wild she may have been raising her first or second infant, but instead she must be cared for as she cannot survive by herself. Our team continue to feed, stimulate, and provide enrichment by giving her tree branches and updating her enclosure at Camp Gemini, but it is difficult not to imagine how different her life would be in other circumstances.

Aan’s future has been determined by the damage inflicted to her by humas in the past, and we hope that she is the last orangutan in our care that cannot go back to where she belongs- the wild.

News from Sumatra - An update from our partners at SOCP

Please read the orangutan update below written by our partners at the Sumatran Orangutan Conservation Programme. Together we are working to protect the habitat and future of all three critically endangered species of orangutan:

Kike Arnal_Arcus Foundation. (1).png

On Wednesday 26th August, 2020, the orangutan post-release monitoring team at the SOCP’s Jantho orangutan reintroduction site, in Aceh province, came across an adult female orangutan. After a quick check to see if they could figure out who it was, they noticed that she was carrying a young infant, no more than a few months old! The baby orangutan is male and is the third baby orangutan born in Jantho since the SOCP's Orangutan Reintroduction Programme began releasing orangutans into the Jantho Nature Reseve in 2011. Mother and baby both appear to be healthy and are behaving just like wild orangutans would. The infant is being carried properly by his mother and has been seen breastfeeding without difficulty on numerous occasions.

After checking some earlier photographs the team are confident the mother is 'Edelweiss', actually the very first orangutan to be released at Jantho back in 2011. After her release she immediately moved away from the camp area and deep into the forest. On February 11, 2020, a female orangutan strongly suspected to be Edelweiss was observed not far from the orangutan reintroduction site and at that time she was showing signs of being pregnant.

The aim of SOCP's orangutan release program at Jantho is to build a new, wild population of Sumatran orangutans (pongo abelii) as a "safety net" or "backup", should a of catastrophe befall the remaining truly wild populations in and around the Leuser Ecosystem. This is especially important in the midst of the current pandemic, as whilst the scientific evidence suggests orangutans and the other great apes are susceptible to infection by the SARS-CoV-2 virus, the effect it might have on them remains entirely unknown.

To date, more than 120 individual orangutans have been successfully released into the Jantho Nature Reserve but many more are needed before the population could be considered genetically viable and self-sustaining for the long term. For this reason, every orangutan released or born in Jantho’s forests is extremely significant and important, and gives new hope for the future of this critically endangered species.

Director of the Sumatran Orangutan Conservation Programme, Dr Ian Singleton said “We always knew it would be several years before we really started to see infants being born on a regular basis among the new population of orangutans we are creating in Jantho. This is because most of the orangutans we release there are 5 to 8 years old, whilst wild orangutan females tend to be around 15 years old on average when they have their first infant. It's great to see these new infants starting to appear though, and it's especially rewarding when you think about all the hard work, spanning many years, that goes into reintroducing each and every one of the orangutans we have released to date. That these new infants have never known captivity and human contact is also extremely heart-warming, and hopefully they never will, unlike their parents, whose own mother’s were almost certainly killed during their original capture and some of whom have endured years chained by the neck or kept in tiny cages at the hands of their illegal owners. The orangutans we are releasing in Jantho, and those now being born there, really are the founders of this entirely new wild population, and it's never been more important to have these ‘back up’ populations as we face the extremely worrying prospect of SARS-CoV-2 infections passing from humans to orangutans, both in captivity and in the wild”.

Orangutan Stories: Suwita

Biologically speaking, humans and orangutans are similar as we share around 97% of the same DNA. It could be said that orangutans also share comparable traits with us when it comes to parenting, as mothers teach their young essential skills for later life, and provide them with shelter each night.

As Orangutan Foundation’s founder and director/trutee, Ashley Leiman, says: “It is very special to watch a mother and infant together. I think the bond is so exceptional because orangutans are solitary. I’ve seen gorillas and chimps with offspring and the whole group is involved in the upbringing. Likewise elephants - if a calf falls over, all the aunties and extended family reach out to pick it up and get it back on its feet. With orangutans, all that care and teaching and relationship is condensed into the mother-infant bond. The mother’s eyes are never off the young”.

Wild female orangutan Suwita has shown these crucial maternal characteristics over the previous weeks as she carefully looks after her new baby and appears to be showing the nurturing instincts you would expect for an orangutan mother’s first offspring.

Suwita was born in the forest near Camp Rasak in 2009 and of the four new wild orangutan mothers discovered recently within the Lamandau Wildlife Reserve, Suwita looks to be the most protective of her new baby.

Our field teams are continuously monitoring wild and reintroduced orangutans inside this protected habitat, and to help keep a visual record of their development, we try and take photographs from a suitable distance. Following careful observations of Suwita, it has now been discovered that her offspring is in fact male and has been given the name Samuel, but it hasn’t been easy to get a clear sight of the young primate.

Unlike the other recent orangutan mothers who almost appear to show off their newborns, Suwita is very protective to the extent that our team initially struggled somewhat in identifying the sex of her infant. When sat on a branch in trees Suwita rests her son securely on her lap to feed, and when travelling through the canopy she always makes sure that Samuel is safe and holding on tight, away from prying eyes.

Suwita is proving to be a doting mother to Samuel. It’s quite possible that her protective nature has developed from memories of her mother Sawit, but whatever the reason, it’s wonderful for us to observe a wild orangutan so caring for her first offspring.

Bursting with life - Primates

We may be the Orangutan Foundation, but our work also protects crucial forest habitat home to a variety of other ecologically significant species. It could be said that the forests we primarily operate in, Tanjung Puting National Park and the Lamandau Wildlife Reserve, are truly bursting with life.

These tropical forests are found in one of the most biodiverse corners of the globe in Indonesian Borneo, where Primates make up some of the most captivating fauna. Bornean orangutans are an umbrella species helping to protect habitat for a number of these arboreal mammals, but here are some of the other primates our field team study, monitor, and observe:

Proboscis Monkey - Nasalis larvatus - Perhaps one of the most unusual species found in the forest and indeed the primate world, proboscis monkeys can only be found in the wild on the island of Borneo. It’s thought that the elongated noses of the males help to attract females, and their round bellies containing two stomachs aid the digestion of leaves that other animals cannot eat.

These endangered primates live in close social groups, often in submerged and swamp forests. This means that sometimes they must swim between trees in search of food and to help them do this, proboscis monkeys have evolved partially-webbed hands and feet, making them expert swimmers and helping them avoid predators like crocodiles in the water.

Macaques - There are two species of macaque spotted by our team; the Pig-Tailed Macaque (Macaca nemestrina), and Long-Tailed Macaque (Macaca fascicularis) also known as Crab-Eating Macaque.

Some roam the forest independently in search of food, but the majority of macaques are found in flexible family groups. They always appear to be on the move and as such are one of the most commonly seen animals captured on our remote forest camera traps.

When it comes to their diet these primates are certainly not picky. Macaques are generally opportunistic omnivores and will feast on anything from leaves and seeds to invertebrates and eggs, it’s this versatility that makes them such a successful primate species around the world.

Langurs - These primates are also called ‘leaf monkeys’ due to their herbivorous diet. Comparatively little is known about their behaviour due to their elusive nature, but our team on occasion have spotted Silver Langur (Trachypithecus cristatus) and Red Langur (Presbytis rubicunda), also known as the Maroon Langur. It’s thought that the White Fronted Langur (Presbytis frontata) has also been caught on remote camera traps in the Belantikan region, another habitat which the Foundation help conserve.

Bornean White-Bearded Gibbon - Hylobates albibarbis - This is another species endemic to Borneo and listed as endangered due to the ongoing threat of habitat loss. Gibbons are neither monkeys or great apes, instead classified as ‘lesser apes’, but are perhaps the fastest primate when it comes to travelling through the canopy. It has been said that their long arms can swing them from branch to branch up to 34mph!

DSCF0101.jpg

Gibbon pairs often mate for life and travel in small family groups. Each morning they will often strengthen this bond by singing a ‘duet’ which can resonate through the forest over a mile away, notifying other groups of their presence.

Western Tarsier - Cephalopachus bancanus - Also known as Horsfield’s Tarsier, these are the smallest primates found in Borneo. It’s understood that tarsiers are some of the oldest living primates, separated into 18 species which are all found in South East Asia.

Tarsiers are the only entirely carnivorous primates. Using their huge eyes to spot prey in the dark and then springing into action using their long legs, tarsiers feed on a range of nighttime creatures, primarily flying insects such as cicadas, moths, and beetles.

Bornean Slow Loris - Nycticebus borneanus - The large forward-facing eyes of the slow loris also indicate that they are a nocturnal species, perfectly adapted to hunt insects and small vertebrates in the trees.

Slow+loris+released+into+Lamandau+by+OF-UK+in+2014.jpg

They may look cute and cuddly, but the slow loris is the only primate known to have venom. Secreted from the brachial gland on their upper arm, it’s not fully understood why slow loris possess a bite which can be venomous. Perhaps this mysterious trait is why slow loris are regarded as the guardians of heaven in some local folklore.

Your support helps us provide a natural home to all of these primate species. Keep up to date on our work and subscribe to our monthly e-news updates to find out what other diverse wildlife species your crucial support protects.

Orangutan Stories: Sheila

Sheila is a female orangutan who was reintroduced to the Lamandau Wildlife Reserve in 2004 and is now one our regular visitors to Camp Gemini within the forest. Her story is one that mirrors many orangutans that have been translocated to the safety of this Reserve, and one that shows how suited this environment is for a healthy population of orangutans.

Sheila and her third offspring Sony forage for food in the trees.

Our field team have monitored Sheila’s progress since her arrival into the forest at around five years of age and recorded all of the major events in her life. From the unfortunate passing of her one-year-old son Shola in 2007, to the births of her daughter Sakura in 2008 and son Sony in 2014. Sakura is now at an age where she can roam independently in the forest, but young Sony is still spotted at camp shadowing his mother from time to time.

Sakura (left) is now an adolescent exploring the forest independently, while Sony (right) is becoming more self-reliant but still stays in close proximity to his mother.

While all three orangutans live entirely in the wild, they are observed by our team when they come near to camp to ensure that they remain in good health. In recent months however, Orangutan Foundation staff saw that Sheila’s throat sack had grown bigger, an unusual occurrence for female orangutans. Males commonly have larger throat sacks, acting as echo-chambers as they produce their resonating long-call through the forest, but typically females do not.

Following some deliberation it was the decision of our vet Dr Dimas that the best course of action would be to observe Sheila more closely and anesthetise her so that her throat could be suitably checked. One afternoon with Sony playing in a nearby tree, our team were able to carefully sedate Sheila and begin their examination.

Sheila+%281%29.jpg

Generally Sheila appeared to be in good health, however a syringe would need to be inserted into her throat sack to check whether it contained excess air or fluid which may need releasing. In reality though, it turned out to be neither of these things. Instead it was discovered that Sheila had an extra layer of fat which fortunately is not suspected to be harmful to her wellbeing. Dr Dimas was happy to give Sheila a supplementary vitamin injection and clean bill of health to go back into the forest.

Her progress will continue to be monitored, but it is tremendously reassuring for our team to know that orangutans like Sheila in this forest are prospering in a protected natural habitat.

Support orangutan habitat for International Orangutan Day

This week please help us protect 300 acres of crucial orangutan habitat to reach our goal on International Orangutan Day, Wednesday 19th August.

This would be a wonderful reward for our team who have continued to work through lockdown, and for the Foundation as a whole on our 30th anniversary. Importantly however, it would ensure that we can continue to protect and reforest a vital biodiverse ecosystem, home to around 5,000 critically endangered orangutans.

Every sponsor between 12th-19th August will receive an email acknowledgement thanking them for their generosity. It can even be bought as an e-gift by entering a name and email address into the ‘Additional Info’ tab during the checkout process.

It costs just £2 to safeguard an area of tropical forest for a whole year, so truly every tree and every penny counts!

Orangutan Stories: Labetty and Suwita

Forget the wet and dry seasons, for the orangutans of the Lamandau Wildlife Reserve at the moment it appears to be baby season! Following the news of Pauline and Queen both giving birth in recent weeks, we are thrilled to report two more additions to the forest from first-time mothers Labetty and Suwita.

It’s not always easy to identify a pregnant orangutan as the signs can be subtle, but in recent months our teams have been keeping a watchful eye on a handful of females who appear to have slightly enlarged bellies, genitals and appetites; one of whom has been Labetty (above).

Labetty is a wild orangutan who our team at Camp Rasak have been observing on her occasional visits since her birth in 2007. Despite her larger size in recent months however, Labetty still appears to be one of the fastest orangutans in the forest and seems to glide through the trees with speed and elegance, regardless of her pregnancy. It was predicted that Labetty would give birth in around a month’s time so it was somewhat of a surprise when she was spotted this week with her new baby, identified as a male.

It would be fair to say that Suwita (above) has also surprised our team this week. It wasn’t until relatively recently that Suwita was identified as another pregnant female, but the duration of her gestation period was unknown. With wild orangutan males Ewet and Tole also spotted from time to time at Camp Rasak, it was thought that one of these males (most likely Ewet) must have mated with her at some point, but when? It wasn’t until this week when Suwita was observed with her young infant that our team knew she must have mated around 9 months ago.

The sex of Suwita’s new baby is currently unknown but our field team and veterinary staff will continue to monitor the progress of her and Labetty in the coming months. We look forward to collecting and sharing footage of the pair caring for their new infants in the forest very soon.

Through their new infants, Suwita (left) and Labetty (right) are contributing to a more secure future for this orangutan population.

To witness four wild orangutan births within a matter of weeks is a remarkable achievement and demonstrates how settled this population of great apes is in the Lamandau Wildlife Reserve. For all of us at the Orangutan Foundation, this news truly feels like a fitting reward on the 30th anniversary of our conservation work, supporting these critically endangered primates and protecting their natural forest environment.

Cause for celebration! The first orangutan birth of the year

It was with great excitement and surprise that Orangutan Foundation staff recently caught a glimpse of Pauline, a wild orangutan rarely seen at Camp Gemini, proudly displaying her new two-week-old baby boy.

Our team are thrilled to welcome the first newborn orangutan of the year, and the first offspring for new mother Pauline. Her infant has been named 'Pancaran' by Ibu Siti, the local Minister of Environment and Forestry. It’s heartening that in the Lamandau Wildlife Reserve, orangutans have provided us with some recent good news and encouragement for the future.

Pauline is the thirteen-year-old daughter of reintroduced orangutan Paula, and spends much of her time in the forest. It’s thought that last year Pauline mated with Carlos, a wild male orangutan who is also sporadically spotted at Camp Gemini. What is just as exciting is that she may not be the only orangutan with a newborn this year, as four other females in the forest also appear to be pregnant.

Our field teams keep a close eye on all of the wild and reintroduced orangutans that visit our five forest camps in the Lamandau Wildlife Reserve, but are keeping particularly close tabs on Labetty and Suwita at Camp Rasak, and Queen and Betli at Camp Buluh who may all be expecting newborns soon. Hopefully providing a bumper year for orangutan births in the forest.

Despite her pregnancy, Labetty is still a speedy climber though the forest

Orangutans take many years to rear their young, which is why having observed 15 births in the past five years alone, our team are proud to see that the Reserve is clearly a habitat in which these critically endangered great apes are not only surviving but thriving. We will continue to protect this vital orangutan stronghold, and look forward to welcoming more new arrivals in the coming months.
