Pigtail Macaque

Matang has one less resident after we felt the effects of being situated within the rainforests of Borneo. A 13 foot reticulated python found its way into the pigtail macaque enclosure on the animal trail and found within a rather tempting meal. It's very likely that this snake, a protected species, is one of the very animals that Matang Wildlife Centre had released into the national park before.



It seemed strange that the python was able to catch the monkey, as if the monkey had stayed at the top of its cage it would not have been in reach. However, the python was presenting lacerations to its back, suggesting that the monkey attacked the snake and unfortunately then found itself in range of the snake's jaws. The python was discovered during morning husbandry - a keeper went to feed the macaque, and instead found a rather large snake in the cage. Thin enough to enter the cage initially, after consuming the monkey the python found itself too large to fit back through the bars and became captive as a consequence.



Keepers here were able to catch the snake with little problem. Its energies were obviously mostly devoted to digesting the huge meal. The python was relocated to an adjacent forested area and released. While it was obviously a shame for the monkey, it was a great opportunity to see nature in action, and a stark reminder that we do indeed work in a jungle!

Chiam and Baby Visit Feeding Platform

During the first three weeks that Chiam was out in the national park, keepers only saw her once as she came to investigate Ting San's rehabilitation training. Though they continued to call for her and place food at feeding platforms twice a day, it seems Chiam was enjoying herself too much to be concerned with coming back when called for easy food. Indeed, during her first 4 hours out, Chiam built 4 nests, which is certainly in excess of what's required! Orangutan will always build a nest for sleeping, and will commonly make one day nest to take a rest from foraging, but four in one afternoon is certainly not seen. It seemed Chiam was simply feeling the joy of the trees once again. However, recently Chiam returned to the feeding platform recently built on the trail to the ranger station.



She came down in response to keepers calling for her, as they have been doing each day twice daily. The aim of this was to let Chiam know that there would always be someone in the jungle to feed her, should she require extra food. This has obviously worked, Chiam had known where the keepers were going to be at what time and responded to their call.



Both her and the baby appear to be in great health and obviously enjoying their time in the trees. It is wonderful to know how much Chiam's son will now be learning about his natural environment, and we can only imagine how fast he will pick up natural survival skills such as nest building and foraging with Chiam as his teacher.



We hope that this will be the first of many occasions that Chiam returns to our feeding platforms for food.

Orangutan Congregation

After the first few weeks when Chiam relished the novelty of the jungle and kept to herself, she has since been coming back to the feeding platform when called regularly. July volunteers were able to join the keepers, one at a time, on the twice daily excursions to the jungle to call and leave food for Chiam. About 70% of occasions saw Chiam returning for food, so the volunteers were lucky indeed.



During one afternoon, we witnessed a first for Matang for a number of years when four orangutan gathered at the feeding platform. Have a look at the photo below and see if you can spot who is who:




All the orangutan present were greatly enjoying the treetops, which made clear photography a challenging task. Check the picture below for more of a clue.





It was certainly a special sight to behold. Chiam was very interested in Ting San, who was initially wary of Chiam but soon gained confidence and would stay in the same vicinity as her, equally curious. Chiam was also allowing her baby to explore the trees on his own, and it was quite incredible to see him practicing the art of climbing in the trees, as previously we had just seen him do this in a cage. Though it was wonderful to be able to observe Chiam's baby close up in captivity, it simply does not compare to watching him practice his natural behaviour in his natural environment. Ali seemed oblivious to the larger apes; he was immensely pleased with the small tree he had found, and spent most of the afternoon swinging it backwards and forwards.



From this day on, keepers have intentionally been bringing both Ali and Ting San to Chiam's location, when she is present. The two youngsters will learn much more from her, a fully competent semi-wild orangutan, than they will their human keepers. It makes our job of rehabilitation a lot easier - we now have an incredibly qualified teacher who, if willing, can continue jungle training with our juveniles.

Chiam and Baby Released

Chiam has long been a favourite of volunteers and keepers alike at Matang. She is a highly intelligent orangutan, and has fascinated many on onlooker with her swift and accurate construction of tools out of mere scraps of rope and left over food items. Chiam's presence at the centre was bitter sweet - it was a joy to observe her and a privilege to get to know her, but she has long been ready for life in the jungle.

Part of the centre's captive breeding program; Chiam gave birth to George's son in February 09. Her infant developed quickly, and Chiam's stress-free approach to motherhood quickly fostered an ambitious and independent son. At just two months of age he was already exploring his cage in absense of his mother and flexing his young climbing muscles on the bars.



In May 09, the decision was made to release Chiam. Her infant had developed extremely well and it was more than clear that Chiam is a competent mother. At the begining of June, Chiam was released into Kubah.

Though it had been hoped to release Chiam, George and Ghanti together, it made good sense to release Chiam earlier. With Mamu being in the rainforest, it is a good step to have a competent adult join her in the environment, so should Mamu have any difficulty in food location or nest building, Chiam can watch over her and offer assistance. Though Ghanti herself would not struggle in the jungle, she is being kept at Matang for the near future so that staff here may keep a closer eye on her infant and ensure its healthy development. He is currently developing well, but Ghanti does not have the carefree confidence in motherhood that Chiam displayed, not surprising since for Chiam, she had done it all before.



As a dominant male, George would not be safe to be released too close to the centre. Therefore, we will still build a release site for him futher into Kubah, which is the task of July 09 volunteers. Over the next few months, keepers will slowly move Chiam through the jungle to this new site, so when it is time to release George and Ghanti, Chiam will be centred on this area also. This will then become the primary feeding area for the 3 adult orangutan, plus the two babies.

Our immense gratitude goes out to all volunteers, past, present and future. For many of those past, you worked tirelessly at the centre and dedicated your money to it for the future when the orangutan you got to know so well would be in a position to be released. Many of you never saw an orangutan in the jungle at Matang, and indeed it has taken many years for us to begin to realise the release plans. Whether you were building a feeding platform for the orangutan, or building a deer enclosure at the centre, it is all of these efforts combined that have brought Matang up to a standard where release of orangutan is not just feasible, but is now happening. We cannot thank you enough and hope that when we collect the first few photos of Chiam in the jungle with her baby you will all consider it your success as well
