Sumatran orangutan Archives

Visitors to Primate World, at Cheyenne Mountain Zoo, may soon notice two crates in the orangutan yard. These crates are part of the Zoo’s careful preparations to help two iconic Sumatran orangutans, 6-year-old Kera and her mother, 37-year-old Sumagu, get ready for their next chapter.

The mother-daughter duo is scheduled to move to another AZA-accredited zoo, likely later this summer, as part of a breeding recommendation through the Association of Zoos and Aquariums’ Species Survival Plan (SSP) for Sumatran orangutans.

Sumagu has a breeding recommendation with a male at another zoo, and keepers are working diligently to ensure the move is as smooth and low-stress as possible.

“Crate training is one of the more advanced behaviors we work on with our orangutans,” Ashton Asbury, Primate World animal keeper, says. “We’re teaching Kera and Sumagu to voluntarily enter the crates and to be comfortable spending time in them.”

Using positive reinforcement training, keepers are helping both orangutans associate the crates with rewards and calm experiences. In addition to watching for subtle behaviors, the team teaches the orangutans to signal when they’re ready to end a training session. This method allows Kera and Sumagu to feel empowered throughout the training process.

“Our goal is for them to enthusiastically enter the crates and allow the doors to close behind them,” Ashton says. “That way, when it’s time for the big move, it’s a familiar and positive experience.”

Thanks to this voluntary approach, neither orangutan will require sedation during their trip. Experienced animal transport professionals will make stops along the way to check on the great ape travelers, offering food and water, and making visual health checks. The teams also collaborate with AZA-accredited zoos along the way, in case the orangutans need care mid-trip.

Sumagu, who was born at CMZoo, will be stepping into a new world as she heads to her new home.

“We’re excited for Sumagu to have this new life experience,” Ashton says. “She’s such a wise and savvy orangutan. She’s very confident, and we’re encouraging her choice and control as she trains. She’s a great communicator. If she needs us to make adjustments, she’ll let us know.”

Sumagu’s daughter, Kera, is also preparing for this next stage in life. At her age, orangutans naturally begin to seek more independence, and Sumagu encourages that independence in Kera. To support this, Kera and Sumagu will travel in separate crates, and then settle into their new home together.

“It’s important for young female orangutans, like Kera, to observe their mothers raising another baby,” Ashton says. “She doesn’t have a breeding recommendation, but she could later. Young female great apes who get to be older siblings become more successful mothers later. Great apes’ offspring typically stay with their moms longer than any animal species, and learning how to be a mom from their own mom is the best-case scenario.”

Keepers at CMZoo will be working closely with the orangutans’ future animal care team, sharing training histories and behavioral nuances, which is essential for complex and intelligent animals like orangutans.

“Kera is such a fun kid,” Ashton says. “She’s serious about orangutan things, like nest-building, but she’s also super engaging and outgoing with people. We will definitely miss both of them, but we’re proud to support this breeding recommendation that supports the population in human care, and continues to inspire conservation for wild orangutans.”

Fans of Kera and Sumagu, and all orangutans, can save the rainforests from the comfort of their smartphones with a free global mobile app called PalmOil Scan, available for free on the App Store and Google Play. It is available in the United States, Canada, the United Kingdom, Australia and New Zealand, with further expansion planned in the future. Orangutan enthusiasts can learn more about palm oil, and download the free app before their next shopping trip, at cmzoo.org/palmoil.

Palm oil is an edible oil that can be found in about half of consumer products. Unsustainable palm oil production results in deforestation in Indonesia and Malaysia, the only places where critically endangered orangutans live in the wild. Although the majority of palm oil production is in Southeast Asia, it has also expanded to other tropical areas, which means more animal species could lose the habitats they need to survive.

When produced sustainably, palm oil is 4 to 10 times more productive than any other edible oil. Using PalmOil Scan, conscientious consumers can scan the barcodes on tens of thousands of products in the app’s extensive database (which is being updated and expanded continually) to see if they are produced by a company that has committed to sourcing sustainable palm oil.

“Orangutans are incredibly intelligent and complex animals,” Ashton says. “Our animal care team knows these great apes really well, and we’re planning for the best opportunities for all of the orangutans in our care as these changes take place.”

Primate World is currently home to six orangutans: three Sumatran orangutans, including Kera and Sumagu, and three Bornean orangutans. When Kera and Sumagu move, male Sumatran orangutan, Baka, will continue his current lifestyle, with access to interactions through a safety barrier with Ember and Hadiah, mom-and-daughter Bornean orangutans. Tujoh, a male Bornean orangutan, will continue to have the same access.

Quarters for Conservation Legacy Project: Palm Oil Conservation
The Roundtable for Sustainable Palm Oil (RSPO) recognized Cheyenne Mountain Zoo’s collaborative palm oil conservation work at the RSPO annual conference in Bangkok last month. PalmOil Scan, a global mobile app that empowers consumers to choose companies that commit to using sustainable palm oil, won the RSPO Innovation Award.

The award acknowledges the work of World Association of Zoos and Aquariums and its members, Cheyenne Mountain Zoo, Chester Zoo, Auckland Zoo and Zoos South Australia, in developing the PalmOil Scan app.

PalmOil Scan is available in the United States, Canada, the United Kingdom, Australia and New Zealand. Learn more at cmzoo.org/palmoil and download the free mobile app before your next shopping trip in the Apple Store or Google Play.

Palm oil is an edible oil found in about half of the products consumers purchase. It is used in candy, soaps, cosmetics, pet food and cleaning products. Because of high demand, unsustainable palm oil production has resulted in deforestation across Southeast Asia, and other tropical areas, which means critically endangered species like orangutans, tigers and elephants, are losing their homes.

However, when produced sustainably, palm oil is the most productive edible oil available. Oil palm trees produce four to ten times more oil than alternatives like soy, olive, canola and coconut. Switching to these alternatives would cause even more deforestation in tropical areas, which is why consumers must demand sustainable palm oil.

CMZoo has been a leader in sustainable palm oil advocacy for nearly 15 years. The Zoo launched a similar mobile app for consumers in the U.S. and Canada in 2014. More than 160,000 verified users have educated themselves by using CMZoo’s app. Its design, database and user experience served as the foundation for the design of PalmOil Scan, which has the potential to reach millions more people around the world.

Through Quarters for Conservation (Q4C), 75¢ from every admission and $25,000 from membership revenue, totaling more than $5 million since 2008, funds legacy programs – symbolized by the Q4C kiosks, where guests can place tokens representing their 75-cent contributions, in CMZoo’s admissions plaza. One long-time legacy conservation effort is palm oil education and advocacy for orangutan habitat preservation.

The youngest ape in Primate World, 6-year-old Kera, puts the “I” in “independence,” according to Animal Keeper Izzy Dones, who works with Kera in Primate World. Kera is one of six orangutans in Primate World, and one of three Sumatran orangutans, along with her mom, Sumagu, and her dad, Baka-Keri.

“I think her independence comes from Sumagu,” Izzy says. “Sumagu really beats to the rhythm of her own drum. She will let you know if she wants to come over to train or if today is not the day. It’s like she has seen it all and knows exactly what she wants, and I love that.”

Orangutans learn through behavior modeling, and Kera is an astute observer.

“When Kera was really young, Sumagu participated in voluntary training with us and Kera watched closely and mirrored her mom’s behaviors,” Izzy says. “Kera learned a lot of her body presentations and stationing that way, which we teach so she can voluntarily participate in her own health care.”

Clever Kera is a whiz at husbandry training. She does an open-mouth presentation so keepers can brush her teeth. A recent dental check revealed another sign the baby orangutan is growing up. She lost her first baby teeth!

“If she’s near the window, guests can open their mouths and show her their teeth, and she’ll usually show them hers,” Izzy says. “She just lost her first two teeth in February, so you might be able to see where she has lost her two middle bottom teeth and her new ones are growing in.”

Kera is also smart enough to know that her behaviors are valuable to her keepers – valuable enough to earn her yummy treats. One behavior, called “trading,” allows keepers to ask the great apes to bring them something from their dens, like small reusable PVC tubes that keepers stash food in. When those tubes are empty, keepers ask for them back.

“Some mornings, I’ll come in and she’s waiting at the fence with a pile of theses tubes she has collected and she’s ready to trade,” Izzy says. “She’s like, ‘Okay you can have these, but only for the right treat and only one at a time.’ She’ll even tear items, like blankets, into smaller pieces so she has more pieces to trade. Her dad does that, too, so we think she learned that little hack from watching him. The more pieces you have to trade, the more treats you get. It makes sense.”

Playful and curious, young Kera loves interacting with guests and keepers. One of her favorite activities is to play tug-of-war. She picks up a blanket and brings a corner of it to the fence so a keeper can pull it through the mesh, and Kera pulls with all of her little orangutan might.

“Kera plays with guests, too,” Izzy says. “She loves to climb up on a rope and swing towards the glass where guests are watching her. She gets really excited when guests start interacting with her. She’s also curious to see what people have in their bags. She’ll get up high and try to look into people’s purses, which always makes me laugh.”

As an ambassador for her species, Kera is a pro. She naturally seeks opportunities to interact and make connections with guests, which inspire them to take action to protect her wild counterparts.

Orangutans are critically endangered, in part because of deforestation to build palm oil plantations in their native habitats. Palm oil is an edible oil found in about half of the products consumers purchase. It is used in candy, soaps, cosmetics, pet food and cleaning products. Because of high demand, unsustainable palm oil production has resulted in deforestation across Southeast Asia, and other tropical areas around the world, which means critically endangered species like orangutans, tigers and elephants are losing their homes.

However, when produced sustainably, palm oil is the most productive edible oil available. Oil palms – the trees that palm oil comes from – produce four to ten times more oil than alternatives like soy, olive, canola and coconut. Switching to these alternatives would cause even more deforestation in tropical areas, which is why consumers must demand sustainable palm oil.

Cheyenne Mountain Zoo, under the direction of the World Association of Zoos and Aquariums (WAZA), helped launch a free global mobile app, called PalmOil Scan, that gives everyone the power to advocate for orangutans’ dwindling wild habitats with their shopping choices, and to make large companies listen to their demands for sustainably produced palm oil.

The free smartphone app empowers consumers to make informed, environmentally-friendly shopping decisions, just by scanning the barcode on a product to see if that company has committed to sourcing sustainable palm oil. PalmOil Scan is available on the Apple App Store and Google Play in the U.S., Canada, the U.K., New Zealand and Australia, with plans to expand to more countries around the world.

PALMOIL SCAN APP^TM NOW AVAILABLE FOR CONSCIENTIOUS CONSUMERS IN AUSTRALIA AND NEW ZEALAND – Auckland Zoo and Zoos South Australia are the latest zoos joining Cheyenne Mountain Zoo (CMZoo) on a worldwide effort, led by the World Association of Zoos and Aquariums (WAZA), to empower consumers to advocate for wildlife with their shopping choices.

Smart shoppers can save the rainforests from the comfort of their smartphones with a free global mobile app called PalmOil Scan, available for free on the App Store and Google Play. It launched last year in the United States, Canada and United Kingdom – and is now available in Australia and New Zealand.

Zoos are stepping up to the task of managing the app’s shopping product database for consumers in different regions. Americans and Canadians lean on the support of Cheyenne Mountain Zoo. In the United Kingdom, it’s Chester Zoo. In Australia, Zoos South Australia is keeping the app going. In New Zealand, Auckland Zoo is in charge. So, no matter the longitude or latitude, consumers can easily make brand shopping choices that help wildlife and wild places.

“We’re excited to welcome Zoos South Australia and Auckland Zoo to the team managing the app,” said Tracey Gazibara, executive vice president at CMZoo and co-chair of the WAZA Palm Oil Subcommittee. “Now, on nearly half of the world’s continents, people have the power to advocate for animals with their shopping choices, and to make large companies listen to their demands for products made with sustainably produced palm oil.”

Palm oil is an edible oil that can be found in about half of the products consumers purchase. It is used in candy, soaps, cosmetics, pet food and even toilet paper. Because of high demand, unsustainable palm oil production has resulted in deforestation across Southeast Asia, and other tropical areas, which means critically endangered species like orangutans, tigers and elephants are losing their homes.

Using PalmOil Scan, conscientious consumers can scan the barcodes on tens of thousands of products in the app’s extensive database (which is being updated and expanded continually) to see if they are produced by a company that has committed to sourcing sustainable palm oil. The free app also has a search feature, so if consumers scan a product that isn’t orangutan-friendly, they can easily choose an alternative that is.

Companies that have previously relied on their customers’ lack of knowledge about unsustainable palm oil and its impact on orangutans, tigers, rhinos, and elephants will soon recognize their competitors have the edge on them.

“Companies that continue to use unsustainable palm oil in their products need to see that consumers have the tools and knowledge to find out whether they value the habitats that so many endangered species depend on,” said Gazibara. “Sustainable palm oil production is possible, and it is time for us all to hold companies to a higher standard.”

CMZoo supporters won’t be surprised to hear the Zoo is continuing its palm oil advocacy work. CMZoo has been a leader in sustainable palm oil advocacy for more than a decade. Under the direction of WAZA, CMZoo helped launch PalmOil Scan, in July 2022. The Zoo launched a similar mobile app for consumers in the U.S. and Canada in 2014. More than 160,000 verified users educated themselves by using CMZoo’s app. Its design, database and user experience served as the foundation for the design of PalmOil Scan, which has the potential to reach millions more people around the world.

“If worldwide consumers show preference for companies that source only sustainable palm oil, we can create a demand that other companies can’t ignore,” said Gazibara. “When more companies realize their potential customers will not stand for the use of unsustainable palm oil, we can prevent more deforestation and help endangered animals recover in the wild.”

In Partnership with Children’s Hospital Colorado

Some cuddle, some snore, some sleep on all fours. No matter how we do it, getting quality sleep is an important part of every healthy routine, whether you’re a human or an animal! Cheyenne Mountain Zoo’s partners at Children’s Hospital Colorado recently shared advice for parents considering what kind of sleep is best for their babies. There are lots of options for helping human infants sleep well, just like there are many different ways animals at the Zoo sleep!

Orangutans might be the most particular sleepers at the Zoo. In the wild and in human care, they make new nests to sleep in almost every day. They usually assemble one nest for a midday nap and another more elaborate nest for their longer sleep at night.

To build nests at the Zoo, orangutans gather large amounts of bedding such as grass hay, wood wool, blankets, big paper bags and tree branches into a pile. Then, they sit in the center of the pile and pat, weave, rearrange, sort and layer the materials until their nest is just right. They typically build nests on the ground and on their tree-high platforms to sleep, but also rest in hammocks, big tubs or separate den rooms.

Young orangutans practice building nests for years before they start sleeping in their own nests as adults. Kera, CMZoo’s 4-year-old female Sumatran orangutan who lives and sleeps with her mom, Sumagu, practices nest building many times each day, but still shares mom’s nest to sleep.

“Orangutans learn by observing others, so Kera has watched Sumagu build nests since she was born and makes her own,” said Dina Bredahl, animal behavior assistant and longtime primate keeper at CMZoo. “Kera routinely flings her nesting materials to destroy her nest when she’s finished building so she can start all over again. Practice makes perfect!”

Like many humans aim to do, orangutans sleep for around eight to 10 hours a day. Tujoh, CMZoo’s 28-year-old male Northwest Bornean orangutan, seems to like the soothing sound of running water when he drifts off to sleep.

“We noticed that Tujoh would tinker with his drinking fountain each night until he made it run consistently,” said Bredahl. “So, we installed a small pool that circulates water and gives him the trickling water sounds that he seems to enjoy for a good night’s rest.”

CMZoo’s giraffe don’t need much sleep. They only rest or sleep for two to five hours a day! Most members of the tower only sleep for one-to-three hours at a time. Some giraffe stand up to sleep, others lie down and some do a combination of both.

“The giraffe who lie down will twist themselves up into what looks like a big pretzel, and rest their heads on their hips with their legs either straight out or folded underneath them,” said Savannah Woods, African Rift Valley keeper. “I’ve also seen Mahali lying down to sleep and using Lakeisha’s back to rest his head while she’s standing next to him.”

They often sleep together in groups at night, but some take midday naps, like 4-year-old male Ohe, who can frequently be seen snoozing in the yard for a brief moment of shut-eye.

Big cats, on the other hand, sleep off and on for most of the day. Taking frequent cat naps allows them get plenty of rest while still maintaining awareness of their surroundings. Mountain lions sleep for up to 17 hours per day! They prefer cool, shady spots in the warmer seasons and sunny rocks during the cooler months. CMZoo’s mountain lions, Sitka, Adira and Koda, can often be found enjoying one of their heated rocks in the winter or the covered, cool spots under trees in their habitat in the summer months.

“Mountain lions are typically solitary in the wild, but have also been observed in social groupings,” said Courtney Rogers, senior keeper in Rocky Mountain Wild. “Our three mountain lions have been together from a young age, so they’re comfortable around each other and have become famous for their big cat ‘cuddle puddles,’ where they sleep in a big pile together by the glass guest viewing area.”

Mountain lions aren’t the only animals that sleep next to each other. Omo, CMZoo’s one-year-old Nile hippo, and his mom, Zambezi, often sleep in a big spoon, little spoon position. That’s only when they’re on land, though. CMZoo’s four hippos usually head to their pools around 2 a.m. to sleep the rest of the night away.

“Omo is getting more independent these days, but he used to use Zambezi as a raft when he was smaller,” said Al Carrier, Water’s Edge: Africa senior keeper. “They still rest their heads on each other sometimes. Hippos are really cool because they sleep mostly underwater and their instincts bring their noses to the surface to breathe every 5 minutes or so, without them waking up.”

Each night, CMZoo’s hippos sleep for about 10 hours and nap for around another three hours during the day. Because they’re so large-and-in-charge, hippos are usually deep sleepers. If something wakes them up while they’re underwater, they can communicate through ‘hippo laughs’ that sound like a snort mixed with an old car horn, without surfacing, to let the rest of the pod know there’s a disturbance.

Wolves, known for their pack behaviors, also sleep near each other but rarely cuddle up once they grow out of puppyhood. That’s not an indication of a lack of bonds, though, for CMZoo’s pack of five Mexican wolves, Navarro, Shadow, Phoenix, Hope and Uno.

“When our wolves wake up in the morning after sleeping for much of the night, they greet each other with lots of face licks and wagging tails, even though they’ve been sleeping near each other the whole time,” said Rogers. “They seem to be light sleepers, always listening and smelling for potential danger. If one hears a noise and wakes up, they often will do a barking vocalization that can also alert the others.”

Wolves sleep around eight hours in a 24-hour period, usually lightly, with a long rest at night or after a big meal and with short naps throughout the day. Uno, CMZoo’s three-year-old female Mexican wolf was seen sleeping deeply when she was a pup, though.

“When they’re young, they often cuddle with their mothers,” said Rogers. “We would see Uno climbing up on top of her late mom, Luna, to sleep right on top of her in the den. She’s also the only one I’ve seen ‘twitching’ in her sleep, like dogs do. We can’t know for sure if she was dreaming, but it looked like she was running in her sleep, so maybe she was.”

Next time you’re at CMZoo, see how your sleep compares to the animals you visit!
