Although Water’s Edge: Africa’s opening date hasn’t been set, Cheyenne Mountain Zoo is steadily preparing to welcome home Zambezi (zam-BEE-zee) and Kasai (kuh-SIGH), two female Nile hippopotamuses who are taking an extended vacation at Dickerson Park Zoo, in Springfield, Missouri. They moved there in 2016 to allow us to build a new state-of-the-art exhibit for them.

Patty Wallace, Water’s Edge: Africa lead animal keeper, worked with Zambezi and Kasai for six years at Cheyenne Mountain Zoo. Wallace spent five of those years as their primary trainer. She is excited for guests to get to know the girls again and to see them in their brand-new home.

Kasai is 20 years old and larger than her older sister, Zambezi. Kasai is easily identifiable by the pink spots on the tops of all four of her feet. Zambezi is 27 years old and has a more consistent skin tone than Kasai. Both hippos enjoy participating in training, but Kasai tends to have a more dominant personality, which often means she’s the first to investigate new enrichment or food.

“I’m really excited about rekindling our relationship and getting to know the hippos again,” said Wallace. “We can expect them to be a little cautious coming into this new building, because they’ve never been there before. Part of the challenge is getting them back to the level of comfort they had before. They’re both really food motivated, so I expect it will take a lot of patience, understanding and watermelon to help the girls gain confidence in their new space and with keepers again.”

Only 30 organizations accredited by the Association of Zoos and Aquariums in North America house hippos. In addition to their somewhat rare presence in zoos, Wallace says part of the CMZoo hippos’ appeal is their generally calm and gentle demeanors.

“Hippos are known as one of the most dangerous animals in the world, with incredibly impressive strength and size,” said Wallace. “Zambezi and Kasai have grown up in human care, so they’re used to people. They may scuffle with each other from time to time, but they really are gentle giants.”

A big part of helping the hippos gain confidence in their new home is training the keepers to control the myriad of new building features that will help them care for Zambezi and Kasai. Keepers are getting accustomed to underwater shift doors, hydraulic doors, garage doors, cable-and-bollard systems, water filtration systems, heating and cooling systems, lighting, behind-the-scenes kitchen and enrichment preparation areas, and more.

“We’re also planning our animal demonstrations and enrichment activities, considering how the girls might like to interact with us in this space and what will give our guests a memorable experience,” said Wallace. “We have a ton of opportunities to help guests fall in love with hippos, thanks to the design of this awesome new space.”

Water’s Edge: Africa’s indoor hippo demo space allows guests to get right up close to the hippos, with only bollards in between them and the animals. In the same area, guests can stand on a scale that helps them see how many humans it takes to weigh the same as a hippo. Near the outdoor hippo yard, a nature trail takes guests to a rope bridge that hangs above the hippo yard, giving guests a first-time bird’s eye view of the girls in water and on land. A knife-edge outdoor pool will help guests see the hippos as the hippos see them – just above the water line.

“You can be eye-level with a basking hippo at the knife-edge pool’s viewing area,” said Wallace. “It is going to be such a cool experience. I can’t wait for everyone to visit the new exhibit and hopefully form long-lasting relationships with these beautiful girls.”

At Dickerson Park Zoo, keepers are working with the girls to make them as comfortable as possible for their trip home to CMZoo, including building the hippos’ comfort level with their transport crates.

“We situated their transport crates so they’re part of the entrance to their yard, which allows them to travel through them and be around them regularly,” said Tracy Campbell, senior zookeeper at Dickerson Park Zoo. Campbell has worked with the girls since they arrived in 2016 and has worked with hippos for 20 years. “Once we have an exact timeline for their trip back to Cheyenne Mountain Zoo, we’ll increase their crate training time, but for now we’re keeping them acclimated by walking through them.”

Wallace was part of the transport training when the girls first traveled to Springfield.

“We trained with them for about three months before their last transport,” said Wallace. “They traveled in separate crates made of wood and steel. Like Dickerson Park Zoo is doing, we positioned the crates as entrances to the building, so they could walk through them and gain confidence with them over time. They were hesitant at first, but since they’re so food motivated, it didn’t take them long to get the hang of it.”

The trip between Dickerson Park Zoo and Cheyenne Mountain Zoo takes about 11 hours. The hippos travel in their crates inside an enclosed and climate-controlled flatbed truck. Once the hippos are comfortably in their crates, a large crane is used to move the 1.5-ton animals onto the truck. During the transport, the hippos are monitored to address any needs along the way. All went smoothly last time, and CMZoo keepers stayed with the girls at DPZ for about a week to help them settle in.

“I’m excited to have the girls home again,” said Wallace. “In the mornings, I would call ‘good morning, hippos!’ and they’d vocalize and poke up out of the water to look for me. They’d watch and wait for me to prepare their breakfast – and they’d let me know if I was being too slow. They’d walk up the ramp and stare at me, watching my every move. I can’t wait to see them and our guests exploring this amazing new exhibit.”

About Nile Hippos

The International Union for Conservation of Nature (IUCN) Red List categorizes Nile hippopotamuses as a species vulnerable to extinction in the wild, estimating 125,000 to 150,000 remain in their native habitats. The primary threats are habitat loss and illegal and unregulated hunting. Hippos are hunted for ivory, which is found in hippopotamuses’ canine teeth, and meat.

Seasonal illnesses, like influenza, can wreak havoc on humans this time of year. But, did you know great apes, like orangutans and gorillas, are also susceptible to the flu virus, which impacts an estimated 3 million humans annually?

As Cheyenne Mountain Zoo’s year-round sponsor, Children’s Hospital Colorado, provides tips for staying healthy during flu season, Primate World keepers take steps each year to help great apes stay as healthy as possible.

“The great apes are the most susceptible to illnesses that impact human primates, like you and me,” said Dina Bredahl, senior lead keeper in Primate World. “Any primate at the Zoo can catch illnesses from humans, but the risk is increased for great apes because they’re so similar to humans. Orangutans share 97 percent of the same DNA as humans.”

To protect the Bornean and Sumatran orangutans and the Western lowland gorillas at CMZoo, the apes receive the flu vaccine. The flu vaccine is administered by injection, which the Primate World residents train to accept voluntarily. Flu shots are available each fall, but injection training continues throughout the year nearly every day. The training can take months and requires the apes to build upon the trust they have in their keepers. Some of them choose not to participate in injection training, or may not be at a point in their training that keepers feel confident a real injection won’t derail the progress.

“We rely on ‘herd immunity’ to protect the population, so not every single great ape will receive a flu shot,” said Bredahl. “As long as a majority of the gorillas and orangutans receive the vaccine, we drastically reduce their overall risk.”

One example is one-year-old Sumatran orangutan, Kera. Little Kera was at a point in her training that her primary keeper thought a real first-time ‘poke’ might risk a regression in her training. Because the majority of the other primates were further along in training, Kera didn’t receive a shot during the fall flu shot clinic. However, her primary trainer continued training, and Kera has made incredible progress. So much progress, in fact, that she gets excited for the training.

“We’ll use a syringe that doesn’t have a needle, so they get used to seeing the shape and being touched with it,” said Bredahl. “Eventually, we move on to a dull needle, so it looks more similar to the needle we’d use for an actual injection. Kera’s trainer has been so successful that Kera now knows if she presents her hip and then holds still for a moment for the pretend injection, she’ll get a special reward. She presents her hip pretty enthusiastically, which is adorable and impressive since she’s still just an infant!”

Keepers also take steps to avoid transmitting diseases to the great apes.

“Primate World keepers receive flu shots yearly to protect ourselves and the great apes in our care,” said Bredahl. “We also wear medical masks when we prepare their food or are in close protected proximity to them. We wash our hands constantly and practice good hygiene before and after we handle anything they’ll touch or eat.”

Guests can visit CMZoo’s three Bornean orangutans, three Sumatran orangutans and five Western lowland gorillas – and can even see their training during scheduled demonstrations – in Primate World.

Cheyenne Mountain Zoo has welcomed two domestic ferrets to The Loft! 1-year-old male, Alfred Pennyworth, and 3-year-old female, Harley Quinn, are already target training, create training, meeting guests and learning how to interact on ZOOMobile programs. Come by The Loft and meet this energetic duo next time you’re at the Zoo!

Bob Chastain, CMZoo president and CEO, is back with the latest update from Water’s Edge: Africa. We’ve refilled the void in the soil under the indoor hippo pool and waterproofed the new concrete. Soon, we’ll do another water test to measure continued water loss.

Get an up-close view of the micro cracks that we’re repairing with a filler product that has some elasticity. We hope the lining material we apply next will stop those leaks.

Also, in this video, we’re giving you a first-time sneak peek at the Water’s Edge: Africa vacation yard. This outdoor yard and pool will be used by a variety of animals and will be visible to guests on their way to Primate World.

Although we don’t yet have an opening date, we’re getting closer! We’re still aiming to begin introducing animals to the building sometime in March. We’ll keep you posted!

Cheyenne Mountain Zoo received an early Valentine’s gift as a second black howler monkey in just under a year was born yesterday.

Four-year-old howler monkey Charlie gave birth to her second baby on Thursday, Feb. 13 at 7:14 a.m. An early-morning staff member was doing a routine check on Charlie and saw the beginning of the birthing process. Keepers say mom and baby are bonding quickly, and early indicators, like the baby’s curled tail, are showing that the baby is healthy and strong. The gender likely won’t be confirmed for several months.

Charlie gave birth to her first baby, Louie, in March 2019. Charlie showed strong maternal instincts immediately after Louie’s birth, and keepers say she has been exhibiting those same behaviors with this new baby, such as grooming and maintaining chest-to-chest contact. Like most primates, the baby will spend its first several weeks of life clinging to mom, and then the young monkey will begin to explore its surroundings on its own.

Even though big brother Louie seems curious about the new addition, touching the baby’s tail while it was wrapped around Charlie’s back, he has been giving mom and baby the space they need to bond.

After Louie’s birth, first-time father Howie seemed unsure of the baby and kept to himself for the first few days.

“Howie’s reacting very differently to this baby,” said Cheyenne Mountain Zoo Monkey Pavilion keeper Debbie Fenton. “He is incredibly calm and sure of himself this second time around. The entire family was able to stay together all day yesterday and remained in the same space last night, too.”

The happy family of four will continue to stay together in Monkey Pavilion, and Charlie has access to a back den area, as well. Since Charlie prefers to be in the main black howler exhibit, guests may have the opportunity to catch a glimpse of the newborn and its family members.

Charlie and Howie were recommended to breed based on their genetics as part of the Black Howler Monkey Species Survival Plan, managed by the Association of Zoos & Aquariums. This baby’s birth is contributing to a program that is working to help guarantee 100 years of genetic diversity for the species in accredited organizations.

Keepers will keep a close eye on Charlie and her baby, and will be happy to share their joy with Zoo members and guests who come to visit.

“We are so excited that Louie will have a sibling to grow up and play with,” said Cheyenne Mountain Zoo Monkey Pavilion keeper Erika Furnes. “He enjoys playfully wrestling with his parents, and we can’t wait to see the two young howler monkeys play together once his younger sibling is old enough.”

About Cheyenne Mountain Zoo

Cheyenne Mountain Zoological Society was founded in 1926. Today, Cheyenne Mountain Zoo, America’s only mountain zoo, offers comprehensive education programs, exciting conservation efforts and truly fantastic animal experiences. It is Cheyenne Mountain Zoo’s hope that guests fall in love with animals and nature, and take action to protect them. Of the 233 zoos and aquariums accredited by the Association of Zoos and Aquariums (AZA), Cheyenne Mountain Zoo is one of just ten operating without tax support. Cheyenne Mountain Zoo depends on admissions, membership dues, special event attendance and donations for funding.

A team of four CMZoo staff members traveled to Ecuador in December to track critically endangered mountain tapir and speak to local school children about the native species.

They successfully studied and attached GPS collars to five wild tapir. The collars will relay data to prove the roaming ranges of tapir in the Andes Mountains, which we hope will be used to establish protections for their threatened natural habitats.

CMZoo members have voted three times to support ongoing mountain tapir research and conservation efforts in Ecuador. During the upcoming Membership Conservation Grant Vote, members will help us decide again which projects receive part of the $75,000 of membership revenue annually allocated for these grants.

Running a zoo requires a substantial amount of water. There are guest facilities, water features in animal habitats, cleaning and sanitation, horticulture, food and beverage services, maintenance and, of course, human and animal water consumption to consider.

Leaning on his background in horticulture, environmental education and ecology, and his involvement in global conservation projects, Cheyenne Mountain Zoo President and CEO, Bob Chastain, decided to make Cheyenne Mountain Zoo the first ‘water neutral’ zoo in the world. So, he worked with the experts at Trout Unlimited (TU) to offset the Zoo’s water usage through a unique new program.

“We use about 16 million gallons of water a year,” said Chastain. “In the last several years through our own internal programs, we’ve reduced our water usage by about half, but we still use a lot of water. We live in a drought state, so I wanted to find a way to give that water back, so to speak, to the rivers in Colorado. With Trout Unlimited’s help, we can do that.”

A nonprofit organization dedicated to the protection and restoration of habitat for trout and salmon, Trout Unlimited (TU) operates a program in the Rio Grande basin of southern Colorado. Under the program, TU arranges for releases of water from storage reservoirs to augment river flows for the benefit of trout populations and the riverine environment. For water year 2020, which runs from Oct. 1, 2019 to Sept. 30, 2020, Trout Unlimited will release 51 acre-feet of water from storage to the Rio Grande River or its tributaries on the Zoo’s behalf. The Zoo donated $15,000 of conservation funds to Trout Unlimited to support these releases.

Chastain is an outdoorsman. He likes to spend time rafting, fishing, hunting and hiking in the wild places along the Arkansas and Rio Grande Rivers. Over the last few summers, he has noticed a distinct decline in river water levels between early and late summer.

“I was rafting the Arkansas River late last summer and the difference in just a month and a half, since I had last rafted it, was dramatic,” said Chastain. “That got me thinking that if there was some way to contribute to water levels when they’re low during the winter months, we could make an impact.”

Roughly ninety percent of Colorado’s water supply is used by farmers and ranchers, according to Trout Unlimited, and this agricultural water use drives rural economies. Rivers also support many important functions in our state: feeding diverse ecosystems of plants and animals; generating tourism and making an economic impact on local business through its fishing, hunting, camping and whitewater sports; and transporting water from reservoirs to those who need it.

“Water rights use and administration in Colorado is extremely complex and each basin operates differently. TU’s approach is to use local staff who engage with water users and facilitate opportunities to do more with a critical and limited resource,” said Kevin Terry, Trout Unlimited’s Rio Grande Basin Project manager. “For instance, TU can inform water users on the needs of the environment and fishery, identifying partnership opportunities that farmers and ranchers can take advantage of if it works for their operations. The whole effort is like a giant dynamic puzzle, and TU brings expertise relating to specific pieces, which helps the water community of the Rio Grande be strategic and holistic in efforts to maximize the benefits of our precious water.”

Cheyenne Mountain Zoo is supporting Trout Unlimited’s program to partner with water users and incentivize them to re-time portions of their water for delivery during the winter months when possible. Restoring stream flows below working reservoirs during the winter months, while simultaneously satisfying water-user needs, creates a better balance of water delivery for the environment, and the people who rely on it.

“We are grateful for our partnership with the Cheyenne Mountain Zoo,” said Terry. “With forward-thinking partners like the Zoo, TU is greatly improving habitat conditions for trout in the Rio Grande basin.”

About Trout Unlimited

Trout Unlimited is a national non-profit organization that works to protect, reconnect and restore habitat for coldwater fisheries.

Simply by visiting the Zoo, Cheyenne Mountain Zoo members and guests contribute to important global conservation work.

“Watching the devastating bushfires in Australia from our living rooms in Colorado can leave you feeling helpless and wondering what you can do to make a difference,” said Bob Chastain, CMZoo president and CEO. “It’s important to note that from every membership and every ticket to the Zoo, we set aside funds to support frontline conservation fieldwork around the world, and specifically now, in Australia. We want people to know that coming to the Zoo is conservation in action.”

Since starting in November 2019, the bushfires in Australia have devastated more than 27 million acres, claiming more than 30 human lives and more than a billion animal lives.

This week, CMZoo members voted to send $20,000 to Zoos Victoria’s Bushfire Emergency Wildlife Fund, in Australia. The funds support long-term care for bushfire-impacted animals, including supplementary feeding and habitat restoration, in conjunction with the Australia Department of Environment, Land, Water and Planning, Parks Victoria, and associated recovery teams. Donations from Zoo employees, board members, docents and an internal Zoo match program raised $6,900 in support of Zoos Victoria, making the collective donation $26,900.

“We have been closely watching the devastation in Australia and working to find the best ways to support the recovery,” said Dr. Liza Dadone, CMZoo vice president of mission and programs. “Last week, we asked our members if we could send a portion of their annual Member Conservation Grant funds to Zoos Victoria. Our members’ collective supportive response was immediate.”

Each year, CMZoo members vote for conservation projects to receive a share of $75,000 allocated from membership revenue. The $20,000 donation comes from that membership revenue. In March, members will vote to guide CMZoo’s decisions about which other projects to support, as they do every year. Since 2015, including this contribution, Cheyenne Mountain Zoo Member Conservation Grants have provided $395,000 of membership revenue to support field conservation worldwide.

“Because our members regularly visit Australia Walkabout at the Zoo, they have formed meaningful connections with the animals they’ve seen in these heartbreaking news stories out of Australia,” said Emma Repp-Maxwell, CMZoo membership and annual gifts manager. “As a leader in conservation, we’re committed to helping people make those connections, and taking it a step further by providing opportunities for our members to contribute to the amazing work being done to save and protect the animals left.”

About Cheyenne Mountain Zoo

As the oldest Canada moose in human care in the United States, CMZoo’s 12-year-old male, Tahoma, has received specialized care for years. Until recently, his issues – including arthritis in his limbs and spine, and an on-and-off cough – haven’t seemed to decrease his long-term quality of life.

Now, Tahoma is showing signs that his pain is increasing, so keepers and CMZoo veterinary staff are working to keep him comfortable for his remaining time. Tahoma’s care team says he’s still eating well, which is a good sign.

Because moose are rare in human care, there’s widely varying data about their average life expectancy. The range we have seen from reputable sources is from 5 to 15 years. But, they have been known to decline quickly once issues become widespread, like this.

“We’ve seen a general slowing down in Tahoma over the last several weeks,” said Rocky Mountain Wild Animal Keeper Allison Rosing. “Specifically, he’s dealing with a significant arthritis-related limp in his front left leg, which he’s been compensating for by shifting weight to his right leg. Because he’s putting more weight on his right leg, we’re seeing inflammation in his right knee. We’ve also seen him ‘hiking’ his head up when he walks, to lessen the weight on his left leg.”

X-rays on Tahoma show severe arthritis in his left leg and other limbs, and advancing arthritis in his spine. His care team has been managing his arthritis for a few years, but recently it seems to be advancing more aggressively.

“We know we’re not going to be able to correct any of this for him, but we can do things to make him more comfortable,” said Rosing. “We’re managing his pain by increasing his anti-inflammatory medications, pain medications and laser therapy sessions. We’re also providing more spaces for him to lie down and rest.”

His team moved some large branches, which he’d previously enjoyed sparring with, out of his barn to make space for a big pile of pine shavings that he can lie on.

“He loves it,” said Basia Dann, Rocky Mountain Wild animal keeper. “He comes in to his barn every night and curls up in his pine shavings.”

Tahoma receives laser therapy on his joints three times per week. Laser therapy is thought to reduce pain and inflammation. Keepers have noticed his limp improving since starting the more frequent therapy regimen.

“Lately he seems more willing to come over and train, which is great because it gives us more opportunities to give him his medications, lots of love and special treats,” said Dann. “In addition to the laser therapy, we have vet appointments with him weekly, so we can track the progression of his issues and make adjustments to his treatment quickly.”

Tahoma’s keepers offer his oral medications – which Tahoma doesn’t seem to enjoy taking – with treats like bananas, kiwi and rye crackers with honey and molasses.

“There’s not a lot known about moose in human care, because there are so few of them,” said Dann. “We’re tracking Tahoma’s issues and overall quality of life, so we can help him stay comfortable for as long as we can, and so we can share information with other organizations whose moose could benefit from it.”

We will continue to keep Tahoma as comfortable as possible while continuing to track multiple factors for his overall quality of life. Stay tuned for more updates on Tahoma as we have them.

Tujoh, a 25-year-old male Bornean orangutan, recently made CMZoo husbandry training history. Tujoh and his primary trainer, Amy Tuchman, successfully completed a voluntary electrocardiogram (EKG) – a test that measures the electrical activity of the heart.

As Tujoh ages, Tuchman and the rest of his care team are looking for ways to take advantage of new technologies to diagnose medical issues common in great apes, like cardiovascular disease.

“It’s especially prevalent in middle-aged male great apes, and all of our guys in Primate World fall into that category,” said Tuchman. “This device allows us to monitor them as often as we like. Early detection could be the difference between life and death, especially for a big guy like Tujoh.”

This new pocket-sized equipment is a welcome advancement for 340-pound Tujoh, who Tuchman describes as a “straight-A student.” The test requires Tujoh to place his two index fingers through the protective barrier between him and Tuchman, onto the quarter-sized metal discs that take the reading. Then, he needs to keep his fingers on the discs with consistent pressure for thirty seconds, continuously.

It only took Tujoh a month to learn how to successfully complete the test. Perhaps that’s in part thanks to his intense focus. Tuchman says Tujoh likes to maintain direct eye contact with her throughout the training.

“He learns incredibly fast,” said Tuchman. “He already knew a ‘hold’ cue, and we built the behavior from there. Once he was sitting on the other side of the mesh from me, I held up my finger and asked him to touch his finger to mine. He’d never done it before, but he got it right away.”

Tuchman cleans Tujoh’s two fingertips before he places them onto the device to ensure the best connection for the reading.

“Now he holds out each finger individually for me to clean before we start, like he’s getting a manicure,” said Tuchman, with a laugh. “He learns how to do something, and he remembers every step you’ve asked of him. Then, he wants to do it that exact way every single time.”

As with most behavior training, the trainers learn from the animals, too.

“The device is made for humans, so we needed to customize how we could present it in a way that allowed trainers to be hands-free to reward his participation,” said Tuchman. “We also needed to securely present it at a level that he could access it while sitting and relaxed on the other side of the protective barrier between us, so we could get an accurate reading.”

Compared to the oversized and complicated readers of the past, these test results will likely be more accurate, because the testing equipment and overall experience are less invasive, thus less stressful for Tujoh.

“It’s still sensitive equipment,” said Tuchman. “That’s a good thing because we know it’s picking up the tiniest abnormalities for us to track, but it also requires a lot of patience and participation from Tujoh to complete the test.”

Tuchman and her team were inspired to pursue the ability to provide regular EKGs for the great apes in their care and attended a conference with Great Ape Heart Project – a coordinated clinical approach targeting cardiovascular disease across all four non-human great ape taxa: gorillas, orangutans, chimpanzees and bonobos. Studies have shown cardiovascular disease is a primary cause of mortality among great apes.

“I’m the primary keeper for Goma [28-year-old Western lowland silverback] and Tujoh, so I was interested in learning how other zoos are managing cardiac care, what tools are available and what we could do to improve our great apes’ cardiac care,” said Tuchman. “Any little improvement we can make to monitor their cardiac health and stay ahead of any issues will be really important.”

Tuchman and her team will share Tujoh’s data with Great Ape Heart Project so they can learn and share data that benefits great apes in human care around the world. They will also continue training with other great apes at Cheyenne Mountain Zoo to utilize this life-saving, non-invasive diagnostic tool with as many participants as possible.
