Re-socialization challenge for an adult female chimpanzee Marilyn

From left: Maruko, Mamoru, and Marilyn. Mamoru seems to want to play with Marilyn.

A female chimpanzee called Marilyn, then 22 years old (estimated), was transferred to the Japan Monkey Centre (JMC) in autumn 2011. She was born in a zoo overseas and relocated at a young age to another zoo, which was using chimpanzees in entertainment shows for the public. She grew up, spent her formative years, at this zoo. When she arrived at the JMC, she didn't possess the social skills required to 'be a chimpanzee among other chimpanzees'. For example, she did not know how to greet her group-mates, or how to interact with them properly. Repeated injuries obliged the JMC to suspend Marilyn's group social life temporarily in order to ensure her health and safety.

However, it is vital for chimpanzees, as very social beings, to be given the opportunity and encouraged to interact socially with other chimpanzees. The JMC staff did not give up hope of being able to provide the social life that every chimpanzee deserves. This is especially important because chimpanzees are very intelligent and have a life expectancy of over 50 years in a captive environment.

A year and a half has passed since the JMC started the re-socialization challenge. Thanks to the devoted efforts of our highly skilled staff, Marilyn has made forward progress gradually, step-by-step. Marilyn now sometimes gives friendly gestures towards her group mates, especially to Marco and Mamoru (Mamoru is Marco's son, born in 2014). They have got used to spending time together, a little bit at a time. Mamoru sometimes invites Marilyn to play with her, though Marilyn still tends to hold back. Marilyn and Mamoru sometimes play together in front of Marco. Yesterday evening, we had some good news: a JMC staff-member saw Marco and Marilyn make eye contact, looking into each other's eyes and grooming each other. Marco has previously been observed to groom Marilyn. However, this was the very first time that we have been able to confirm that Marilyn groomed Marco in return! The JMC continues to be committed to encouragibng social interaction among all JMC chimpanzees.

Joint International Symposium
The 6th International Symposium on Primatology and Wildlife Science and The 5th CCT-Bio International Workshop on Tropical Biodiversity and Conservation

We held an art competition for children to create pictures of JMC nonhuman primates. The awards ceremony took place today. The award winners described to us very vividly the primates they had chosen to draw. We knew that it would be an enjoyable and fun experience for the children to watch the animals. The winning artwork is exhibited at the Africa Center. Please take a look at the children's dynamic paintings.

Summer Camp for Children
We hold an annual two-day summer camp for children, thanks to a fruitful collaboration with "Uny" a company that operates a chain of supermarkets in Japan. This summer, children from 10 to 12 years old, who applied to join this popular camp, underwent a screening process. They were required to submit an illustration and essay on the subject "my favorite living creature." We carefully assessed their artwork and essay to choose who we would invite the Japan Monkey Centre. We invited a total of 24 children, who came unaccompanied by their parents, spent two whole days with the JMC staff, staying overnight in between. The children observed the JMC nonhuman primates and deepened their knowledge of them, with the assistance of the knowledgeable JMC staff. They were treated toed a ‘behind the scenes' tour with our zoo caretakers and had a chance to experience working as zoo caretakers (preparing meals for the non-human primates). They also made their own meal for their dinner by themselves. They first knapped a stone and, in this way, made a stone tool. They even cut up meat for a curry using this handcrafted stone tool. They also experienced several special events at the zoo after closing-time. On the second day, they invented new enrichment devices based on their observation fo the primates' behavior earlier that day. For example, they made a bamboo swing for the chimpanzees. We hope their unique experiences at the summer camp will inspire them to takeaction to conserve these precious non-human primates.

At the JMC, they had the pleasure of seeing Japanese macaques washing sweet potatoes and watching chimpanzees ant-fishing. At PRI they observed chimpanzees carrying out a computer task at a touch-screen station positioned over ten meters above the floor of a spacious new enclosure, part of their living space.
