Amount Raised to date:


Confiscated in February 2004 and released in Jambi in October of the same year, Leuser survived happily in the wild in Jambi for two years. Unfortunately, in late 2006 he wandered near a village at the forest edge and was shot 62 times with an air rifle, including pellets in both eyes, rendering him totally blind.

He was returned to the quarantine centre near Medan in November 2006 for medical care. Only 14 of the 62 pellets could be safely removed from his body. Leuser appears to have made a full recovery from his injuries although we can’t be certain what the long-term effects will be.

He was introduced to another blind orangutan, the female Gober, during 2010 for companionship. Gober fell pregnant and produced healthy twins in February 2011. Since the pregnancy the father, Leuser, has been housed separately. We plan to reintroduce the family, very carefully, in 2012.

Leuser is estimated to be around fourteen years old and is maturing into a large male. He currently weighs approx. 65 kg and should eventually reach around 100kg. Apart from blindness, he appears totally fit and well, has a good appetite, and behaves exactly like a normal orangutan of his size.


Update from Leuser's Keepers - July 2015

Leuser has had an extraordinary 6 months at Quarantine. During this time, we have seen Leuser weigh 60kg and grown to almost 100kg!!! Leuser has also developed his cheek pads, and we expect he will continue to develop these over the next 2 years. Staff have been working really hard to occupy Leuser, whilst he is confined to his Permanent home. They have been working hard on increasing the enrichment and interactions with him. Leuser does not like a lot of change in his day. He likes consistent staff, so his two main staff include Edy and Ariesta. Both keepers spoil Leuser with various activities. He really enjoys his hessian sacks and blankets, so he can make beautiful comfy nests. He also likes to play with the Aussie Dog balls, where treats like peanuts and chopped up fruits are inside. Furthermore, he also has coconuts, sugar cane, dry leaves and jam smears placed throughout his cage. Leuser is excellent in shifting into his little off limit cage, so this makes it easier to work with him in captivity. It also breaks up his day and allows the staff to enter several times to place his food in different positions. As he is very large now, staff have to keep him active both mentally and physically. 
SOCP has also noticed Leuser beginning to long-call. This vocal is a way of identifying his territory at the quarantine station. Even though he is not the dominant male, he has started to practice and it is a very beautiful thing to hear.

SOCP aims to have Leuser new facility built by October. But more funds are required to finish this project. You can check out the developments HERE.

Update from Leuser's Keepers - November 2014

Leuser has had his entire home renovated in the last six months, which meant that he needed to change his location to the Isolation clinic. During this time, we noticed he developed very fast, with cheek pads starting to form! He continues to be the sweet and charming male in the centre, where he loves to eat mangoes and grapes. Staff have started training him to open his mouth, present his shoulder for hand injection and also present his hands. This will aid keepers to perform better medical practices, if Leuser requires maintenance in the near future. Leuser has responded extremely well to this!
Another change in his daily routine, is he receives leaf branches twice daily. We all know how much Leuser loves to build nests, so he has been very happy making his day nest and relaxing until he gets fed at 2pm again. Leuser also enjoys his daily enrichment with lots of boxes and sacks displaying his food in various ways, forcing him to problem solve more than usual. Leuser recently in Ocotber was moved back to the Permanent cage facility, where he enjoyed the newly decorated residence.

Update from Leuser's Keepers - July 2013

Leuser is developing to become a very handsome male orangutan. As he develops, so does his strength! Keepers have gone out of their way to really make sure he is mentally stimulated whilst in his cage. Every night the keepers give Leuser a lot of leaf material, so he can build a comfortable nest. Leuser loves building nests and is very good at it!

Leuser is still lonely. He looks towards the keepers for attention. He loves his head being scratched and his fur being groomed by the staff. He makes small pleasure grumbles and will often move to indicate what area he wants groomed.

When it comes to food time, he is very inpatient. He will often ‘kiss squeak’ and inform the keepers to hurry up and feed him! The keepers always prioritise Leuser's food first, otherwise he will get upset at having to wait too long! Leuser has no favourite food; he is fed 6 times per day. Usually orangutans will feed frequently and sleep. At SOCP we aim to do this with all the orangutans.

Leuser finds it hard to see, so when the keepers feed him, special care is taken to ensure he takes all the food and does not leave any behind.

Leuser will be undergoing some new training plans in the next few months to get him moving and stimulated. He will need to be able to problem solve and aim to move around a lot more independently when he goes onto his new island home. This will take a very strong bond between the keepers and Leuser so he can build trust and confidence.

Keeper Activities:
As a part of an April campaign to raise much needed funds for Quarantine and improve husbandry conditions we set about developing an internal staff competition.

The goal was to upgrade the current Quarantine Centre and implement a team program.

  1. Improve the orangutan welfare and husbandry
  2. Improve the Quarantine practices
  3. Clean up and organise the centre so staff can work more efficiently
  4. Increase staff motivation – Reward those that are doing a good job.
  5. Implement staff quarantine protocols for each area they work in
  6. Staff to implement a management system in the areas they are delegated to work
  7. Increase the communications with the Quarantine Centre – between technicians, veterinarians and managers

The competition was judged by Ian Singleton and Jessica McKelson. A number of good improvements were made to the Permanent Cage facilities where Leuser resides.

  • A new enrichment device to help teach him to problem solve for food. This treat log encourages Leuser to use a stick and other tools to acquire honey or treats.
  • New blue barrels and hammocks installed in Leuser cage.
  • New paint and full scrub over his home!
  • Additional, the entire Permanent cage facility had new paint, new tools and some new overall maintenance to tidy the space up!
