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.

Primates: Quality Family Time

An orangutan takes a burlap sack enrichment item to be enjoyed from up high.

When I heard about the special Inside Look tour offered during Discovery Days: Absolutely Apes at the San Diego Zoo, it seemed like the perfect “experience gift” for my husband. Even though I work at the Zoo, we enjoy playing “tourist” sometimes…and with behind-the-scenes ape ops, well, it was the ideal Valentine’s gift!

The walking tour took us through Lost Forest (for the first time I didn’t get lost!) and our enthusiastic guide, Kindra, showed us some monkeys along the way and explained the Zoo’s participation in the national Species Survival Plan (SSP) and how we keep the lives of our primates interesting with a variety of enrichment items and husbandry training sessions. For instance, one female spot-nosed guenon is diabetic, and keepers are able to get her into a training chute, turn around, and present her leg or shoulder for an insulin shot. She is rewarded with Craisins.

On our way to the apes, we stopped to speak with Jackie, a keeper of 15 tufted capuchin monkeys. These house cat-sized monkeys are highly intelligent, incredibly dexterous, and can fly through the trees like wind. Speaking to their intellect, they have been described as “chimpanzees in little capuchin suits.” Jackie showed us how the alpha male, Ozzie, likes to trade things with his keeper, slipping twigs and other offerings through the mesh to get a nut from her in return. There’s no denying the capuchin’s clever, problem-solving capabilities!

There are no more than 60 bonobos in zoos in the U.S. and Europe.

Bonobos (formerly called pygmy chimps) are raucous, yet largely peaceable great apes that live in matriarchal groups. Our small tour group was on a platform above the exhibit with longtime bonobo keeper Mike, who shared the ins and outs of bonobo life and what it takes to look after this extraordinary primate.  “Being a bonobo keeper has made me a better dad,” said Mike, “and being a dad has made me a better bonobo keeper.” He proceeded to provide his charges with a “scatter” of food, which generated much vocalizing from the apes. I had never heard their deafening calls when observing them from behind the exhibit glass. Mike has a great deal of respect for the bonobos and shared how they are trained to place their arm through a tube and hold still so keepers can get blood draws or administer medicine when necessary. “In the old days, we had to knock down an animal when we needed a sample or a good look at them,” he said. “Now their lives, and ours, are less stressful thanks to training.”

Our next stop was gorillas. Giddy with excitement, we approached the barn-sized back gate and met keeper April, who ushered us to the gorilla bedroom area, where we peeked from a respectable distance at silverback Maka. I gasped with pleasure at the salty, earthy gorilla scent.  Despite a genetic anomaly that left him a bit smaller than most adult male gorillas, he was an imposing presence. April described the gorilla groups like she was talking about her extended family. There are two gorilla troops at the Zoo and lone male Maka who all take turns out on exhibit. The bedroom areas are spacious and bathed in natural light from several sunroofs.

Frank, our youngest gorilla, is now 3 years old!

April led us up to the roof, where we took in a bird’s-eye view of Paul Donn’s troop. She tossed raisins and broccoli into the exhibit as she “introduced” us to the group. Sweet-faced Imani is one of my all-time favorite gorillas. If I had more hair and was a better knuckle walker, I’m pretty sure we’d be BFF’s. And little Frank is not so little anymore, yet he still sports a white rump patch, the badge of a youngster, and is filling out into a robust little lad. He plays with and copies his mighty father, Paul Donn. I count myself fortunate to share the planet with such noble creatures as gorillas.

We concluded our special great ape tour at the orangutan exhibit, where Janey and company were celebrating her 50th birthday. Though in the wild orangutans would happily live a solitary existence, at the Zoo they seem to enjoy each other and even the lanky, long-armed siamangs that share their exhibit. Their fluid, agile brachiation through the exhibit reminds me how important forests are to more species than I can count, as well as to our closest living relatives, the great apes. This tour has been a glorious glimpse into the rich lives of our simian brethren. Hooray for quality family time!

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.

Orangutans Inspire Visitors

I must say that Janey and Clyde, the orangutans, have been great conservation ambassadors during our daily keeper talks at the Absolutely Apes exhibit at the San Diego Zoo. Just under a year ago, I began to develop a conservation package that would some day becomepart of a pilot program for the rest of the great ape areas of the Zoo (see Juan’s blog, New Age Orangutan Conservation). Our conservation package includes materials and products that are made of sustainable and/or reused material; these were used as tools to show Zoo visitors options that we, as consumers, have for becoming more eco-friendly at home.

We also display a poster that illustrates an array of products, from cookies to cosmetics, containing palm oil as an ingredient. Deforestation for the production of palm oil plantations in Southeast Asia is the Number One threat orangutans face in the wild. With less than 65,000 Sumatran and Borneon orangutans left, it is critical that we help out by simply becoming more conscious consumers. With Janey, Clyde, and the rest of the orangutan family right on the other side of the glass during the presentations, guests walk away with an appreciation and respect for these complex creatures.

The San Diego Zoo will be celebrating Great Ape Awareness Days today through November 16, 2008. There will be six scheduled presentations daily at the orangutan, gorilla, and bonobo exhibits. Each presentation focuses on issues great apes face. Here’s the presentation schedule. We will see you there!
