Orangutans Clyde and Cinta

We are so proud of Clyde!

We are so proud of Clyde!

Clyde is doing really great at the Rolling Hills Wildlife Adventure in Salina, Kansas (he moved there in May 2011, see post Changes for Orangutans). Clyde and Rusa continue to get along well. Both animal staff and animals alike love Clyde. He is the only male with whom female Ruse has been paired that she likes! But who wouldn’t like Clyde? He is the sweetest male, and all the girls like him (well, except Indah, of course). There is not any expectation of an offspring from them, though. Rusa has some reproductive issues that would make getting pregnant very difficult. A baby would be a happy surprise. The keeper there was telling me that Clyde is funny about his browse; he is turning his nose up at the Midwest varieties of trees and leaves.

After a few setbacks, Cinta is with all of the orangutans at the St. Louis Zoo (he arrived there in October 2012). Originally, the staff was planning on introducing Cinta to the mother and daughter there, hoping for a successful pairing with the older female. Unfortunately, the females had a different idea! While reevaluating the situation, the staff noticed that Cinta and Robbie, their 19-year-old male, seemed compatible. They were separate from one another but were sharing food back and forth and hanging out near one another. Staff never planned on introducing the two males, but they decided to try and then, later on, Robbie and Cinta could together be reintroduced to the girls.

This has proven to the best of solutions. Cinta and Robbie are now best of friends! They hang out together and share food. Just last week, staff put all four together with a much-improved outcome. ☺ Now, whenever there are any problems, Robbie steps in and defends Cinta (not that Cinta needs much help—he is much faster that the girls! Keepers are very positive about the improvements they have seen and expect things to continue to get better. We will keep our fingers crossed for a successful pairing!

Orangutans: Planned Parenthood

Is Indah ready to become a mother again?

Is Indah ready to become a mother again?

We have just been given the go-ahead by the Species Survival Plan for orangutans (a part of the Association of Zoos and Aquariums) to have a baby with San Diego Zoo orangutans Indah and Satu! Indah has been taken off birth control. She was on birth control because we did not want her to become pregnant while raising her son, Cinta. Typically, sons stay with their mother for eight to nine years. Indah had been implanted with a device similar to Norplant in humans, so she needed a trip to the vets to get it removed. Just like with humans, it may take a while for her hormones to balance out. We are hoping that this time next year we will have a pregnancy or may be even a baby!

The siamangs and the orangutans get along for the most part. The assertiveness of the siamangs directed toward the orangutans at feeding times is behavior seen by researchers in the wild. We do see positive interactions with Indah and the siamangs. She shares food with them (and Satu, too!). Also, she has been playing a lot with Unkie, our male siamang, wrestling and wearing him on her head! It is really amazing to watch.

Even though our female orangutans have been hand raised, they are still wild animals. Their behavior is unpredictable, and, as such, we do not go in with any of them. There is plenty of keeper interaction with each individual with a protective barrier between ape and keeper.

Orangutans: Change is Good!

This photo of Satu was taken in June.

It has been more than six months since orangutan Clyde left the San Diego Zoo for Kansas, and I am happy to say that things could not be going better both here and in Kansas at Rolling Hills Wildlife Adventure! (See Tanya’s previous post, Changes for Orangutans.) After his initial quarantine period, Clyde was introduced to his new exhibit and Rusa, his new, potential “girlfriend.” Both took to each other, and no problems have been observed between them. Previously, Rusa had been paired with younger males, and they were not to her liking. With Clyde, she immediately solicited him, choosing to be close to him (a behavior not seen with her before). In fact, the only issues the keepers there have reported is difficulty is getting them to separate from one another for husbandry needs. It is so great knowing that Clyde is doing so well and that the keepers at his new zoo love him and are taking such great care of him.

Our own introductions with Karen and Satu went with little of the issues we were expecting. Satu was excited to be with Karen and chose to spend nights with her, especially at the beginning. But a lot of the breeding behavior that we were worried about never became an issue. Karen would submit to Satu, and we had little-to-no rough behavior. Karen does have hair loss on her back as a result of her contact with Satu, but since the breeding has decreased in duration and frequency, we expect her hair to grow back in soon.

It was the girls that had to work out their issues. Orangutans are solitary by nature, and females do not interact with each other. With three females on exhibit, they had to work out territory and tolerance for each other. We have noticed an increased use of the exhibit by Indah, and anyone who has spent any time watching the orangutans can tell you that Indah has her favorite spot and tends to stay there. We are very happy about this turn of events, as it lets us know that she is more comfortable in the exhibit without Clyde in the area.

We can already see changes in Satu as he grows into adulthood. His hair is longer, more wavy, and forming dreadlocks. His weight is up (190 pounds or 86 kilograms now!), and his checkpads continue to get larger. He is becoming an adult! Fortunately, he is keeping his same, sweet behavior. He has father Clyde’s disposition. Keep watch at the orangutan and siamang exhibit for more changes to come with Satu.

Changes for Orangutans

We expect to see some changes in Satu.

After being with us for more than 15 years, it is with both a happy and heavy heart that we say good-bye to Clyde, our “gentle giant” orangutan, as he goes to another zoo to be paired with a female there.

As a result of Clyde’s move, we will be able to have all of our orangutans on exhibit every day here at the San Diego Zoo. We are very happy to be able to do this and expect to see a few changes in our group dynamics with Karen joining Satu, Cinta, and Indah. We believe everything will work out well, but because Karen has been separated from Satu for over a year and a half, there are natural behaviors we will be seeing as they work out their relationship.

As a young male, Satu will be excited to see Karen and will want to breed with her. The sessions can be prolonged in duration, but this behavior is natural and will dissipate with time. It can be uncomfortable to watch; the best thing we can do is let them work out their relationship. Though the tendency will be to interfere, the more we do, the longer and more difficult the process could be. We will be having people there observing, making sure that everything proceeds as planned. We fully expect to have a happy, cohesive group of orangutans!

Another change that we will see is in Satu himself! Satu still has his subadult physical characteristics. Because he was with an adult male, the growth of his secondary male characteristics (cheek pads, long hair, and increase in muscle mass) has been suppressed. We are all excited to see the changes in Satu as he develops into an adult male orangutan and are curious to see how quickly they will happen once Clyde has left.
