Imagine answering a knock on your door to find a furry, scaly or feathery CMZoo animal ambassador peeking through the peephole. That dream could be your reality thanks to CMZoo’s Animal Grams program!

Animal Grams are paid off-site visits from a CMZoo animal ambassador and EdVenture staff member. Each visit lasts five to ten minutes and includes a one-of-a-kind art piece created by a CMZoo animal.

“I absolutely love this program because the reactions from the people we visit are pure joy,” said Dawn Moon, EdVenture Outreach Supervisor at CMZoo. “Usually, the door opens, and they see an opossum, snake, or bird waiting to meet them, and they let out a huge, ‘oh my goodness!’ It’s so much fun, and the animals seem to enjoy the new smells, sights and sounds, and getting lots of yummy rewards for choosing to participate in the program.”

Animal Grams can be booked in a variety of ways for a variety of celebrations. Staff travel locally (mileage charges may apply for visits more than 30 miles from the Zoo) to people’s homes, offices and more for these quick visits, which can be spent however the recipient prefers. Staff can provide an educational talk, or just let you sit with the animal quietly, or pose for photos together.

With graduations, Mother’s Day, Father’s Day and more around the corner, now is a good time to book the best surprise ever for the person you want to celebrate this summer. Or, for no reason at all.

“Some people schedule an Animal Gram for themselves, which I think is a creative way to show yourself some love,” said Moon. “We sat and talked for a few minutes while she enjoyed the visit. It was totally uplifting for her, and I thought it was a really great way to give herself a little boost.”

After seven years of settling in, the Western lowland gorillas at Cheyenne Mountain Zoo are officially a cohesive troop! 32-year-old Goma – the troop’s silverback – is living with the four females full-time, which means they’re ready to take the next step as a family.

Goma came to CMZoo on a breeding recommendation in 2016. Joining a tightly bonded group of females was no easy task for the silverback, who came from a bachelor group without much experience living in a traditional family unit. He had to learn how to lead and communicate with females, 30-year-old Asha, 30-year-old Kwisha, 42-year-old Juju and 46-year-old Roxie.

“It’s a fine line because he had to gain their respect, but also show them respect,” said Jon Wild, lead keeper in Primate World. “Now that they’re living together comfortably all the time, we can start working on one of the main reasons he came here: to hopefully help bring a bundle of joy to the group.”

The Western Lowland Gorilla Species Survival Plan recommended Goma and Asha to breed, and although Goma has no experience in that department, they’re hopeful Asha will lead the way. In the coming months, keepers will end Asha’s oral contraception (birth control).

Keepers have seen ‘flirting behavior,’ from Asha, where she’ll sit extra close to Goma or stare intensely at him. She throws hay and plays near him to get his attention, but Goma hasn’t responded. The end of birth control means Asha’s hormones will shift, so it’s likely she’ll be even more motivated to get on his radar. If Goma were human, some might think he’s playing hard to get. What’s more likely is that inexperienced Goma simply doesn’t know what to do yet.

“We haven’t seen any breeding behavior from Goma yet,” said Eleanor Knox, senior keeper in Primate World. “That’s not the case with confident Asha. She’s quite interested in him. Asha and Goma sit, sleep and eat comfortably near each other, within about five feet, which is promising. He’s learned so much already, so we’re hopeful he’ll be able to learn this new role, too.”

Asha has experience as a teacher. She previously taught breeding behaviors to another silverback. Of all the females, keepers say Asha led the way in helping Goma get settled into the troop. With the change in her hormones, the rest of the troop will likely adapt to her behaviors, too.

They’re a family that lives together 24/7, so, like any family, they have disagreements and they work them out in their own way. To communicate they’re not thrilled with something that’s happening, gorillas will ‘stiff stance,’ which is when a gorilla stands on all fours with stiff front arms while facing another gorilla intensely. They also chase, vocalize, or make noise with objects near them. This might look alarming to the untrained eye, but it’s all normal conflict resolution for gorillas.

Juju has mellowed out in her advanced age and after bouts of health issues. She very rarely initiates conflict anymore. However, she’s happy to participate with a grunt from a distance and a little chase, or she might dish out a signature ‘bop’ on the head as someone chases by her.

Because the keepers know the gorillas so well as individuals, they can identify behavioral changes and look for physical changes that could indicate pregnancy. Weight is a factor, but gorillas are naturally round-bellied, so keepers will depend on scale training and specific weights, rather than whether a gorilla ‘looks pregnant.’ Similar to humans, gorilla pregnancies can also be confirmed with a urine test.

“Guests sometimes ask if they’re pregnant now,” said Knox. “Asha and Kwisha, our younger two females, have round bellies. It’s understandable why guests might think that. Obviously, if there’s a pregnancy, no one would be more excited than us, and we would be shouting it from the mountainside when the time is right.”

The team is hopeful for a baby for a variety of reasons. Having kids in a gorilla troop generally helps make a cohesive troop even more bonded. Asha has two offspring, 16-year-old female Tumani and 10-year-old male Dembe, who now live at other zoos accredited by the Association of Zoos and Aquariums. Having young gorillas in a troop is a natural part of gorillas’ dynamic and it’s enriching for everyone to have a baby around.

“Roxie is in the last years of her life, and she has loved playing with the kids in the past,” said Knox. “We would love to see her enjoy that role as a grandma one more time. We also want to help maintain the species, and there’s nothing like a baby to get people’s attention and inspire a new generation of conservationists.”

Western lowland gorillas are critically endangered in the wild. In addition to disease and poaching, they face habitat loss due to logging for agricultural use, human settlements and mining. Many of the west African lowland forests and swamps that these animals call home contain natural deposits of coltan, a mineral used in cell phones and other electronics. Due to the ever-increasing demand for cell phones across the world, the destruction of these gorillas’ habitats for mining purposes has unfortunately only increased.

Coltan is recyclable, and by donating old cell phones, gorilla advocates can supply valuable coltan for future phone production. In Primate World, guests can deposit their old and unused cell phones in a recycling bin near the gorilla habitat. CMZoo sends them to Eco-Cell, an organization that recycles the phones, as well as tablets, smart watches, Bluetooth devices, GPS devices, e-readers, digital cameras, handheld gaming systems and their accessories.

CMZoo will provide updates on the gorilla troop’s progress as the group reaches milestones.

Cheyenne Mountain Zoo has reached a huge conservation goal: reducing its overall annual water usage by nearly half. To offset its water usage, CMZoo also continued a commitment to Trout Unlimited’s water conservation efforts right here in Colorado.

You can’t make homes for hippos and penguins without a whole lot of water, but CMZoo’s previous aquatics building was never going to meet the Zoo’s long-term water saving goals, due to outdated life support system design. From 2009 to 2017, CMZoo used an average of 29 million gallons of water per year. Now, thanks to creative solutions throughout the Zoo and techniques and technologies in Water’s Edge: Africa, the Zoo uses around 16 million gallons per year. That’s a forty-five percent reduction in water use and a savings of 13 million gallons per year.

To offset the environmental impact and to reduce water usage, the team got creative and specific, by:

  1. Designing a new hippo habitat with more efficient methods of water filtration than the old aquatics building possessed.
  2. Improving animals’ water quality and reducing water used in animals’ habitats by fine-tuning water testing and filtration methods.
  3. Catching water that was previously drained when the hippo pools were vacuumed.
  4. Installing pumps to improve water pressure and reduce water volume on hoses used to clean animal areas.
  5. Reinforcing a ‘water aware’ culture throughout the Zoo, with leaks reported more often and repaired more quickly.
  6. Offsetting the 16-million-gallon annual usage by funding the release of equal annual amounts into the Rio Grande basin of southern Colorado.

“Water conservation really is about collectively saving every single drop we can,” said Nicole Chaney, CMZoo conservation and sustainability coordinator. “It’s wild to think that by making a minor adjustment to the hippo pool vacuum, we saved 1,883,400 gallons of water per year. I hope CMZoo guests and fans will look for opportunities in their own homes – even if they don’t have a huge river pool that houses four hippos – to look for small changes that can make big impacts.”

CMZoo guests also make a contribution to water conservation efforts by supporting the Zoo. Every visit to CMZoo is conservation in action. CMZoo recently continued its funding support for Trout Unlimited (TU), a CMZoo conservation partner and nonprofit organization dedicated to the protection and restoration of habitat for animals that rely on our local rivers, which operates a program in the Rio Grande Basin of southern Colorado.

Under the program, TU arranges for releases of water from storage reservoirs to restore river flows for the benefit of fish populations and the riverine environment. From 2019 to 2021, the Zoo donated $45,000 to support the water releases. For 2022 usage, the Zoo donated $20,000 for Trout Unlimited to release 65 acre-feet of water (which translates to 21,180,315 gallons or 50 football fields one foot deep in water) from storage into the Rio Grande River or its tributaries.

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.

CMZoo supports TU’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.

Water rights are complicated in Colorado, but the experts at TU have established partnerships with water rights holders so TU can lease and re-time water rights that are used to restore waterways while benefiting the San Luis Valley communities. The annual water use volume that CMZoo uses is purchased and then released back into streams in the winter months, helping to restore winter flows to the Upper Rio Grande Basin.

Every drop of water saved helps wildlife and wild places, so look around your own habitat to see what small changes you could make. Colorado Springs Utilities offers rebates and incentives for locals who install water-saving appliances, like high-efficiency toilets and showerheads.

Update: April 26, 2023
Last month, 2-year-old Alaska moose, Atka, had surgery to remove a toe with progressive bone degradation from his front left foot. Since then, the ‘Prince of Rocky Mountain Wild,’ as he’s called by his keepers, has been leaning on the trusting relationship he has with his care team to continue his recovery.

“We’ve been really impressed with Atka,” said Erika Furnes, Atka’s primary trainer and senior keeper in Rocky Mountain Wild. “When an animal needs to go through something major like this, there’s always a chance you could lose some of the trust you have built with them. We have to ask a lot of Atka right now, to give him the best possible care, and he’s doing a really great job.”

Since his surgery on Feb. 28, 2023, Atka has been voluntarily participating in his recovery, which started with 13 days of barn rest following his surgery. On April 10, Atka’s care team decided his wound was looking good enough for the big guy to go outside.

“The plan was always to listen to what Atka was telling us during his recovery, and to balance what’s best for him medically with what’s best for him as a moose,” said Furnes. “After nearly two weeks, he was ready to stretch his legs in the sunshine. By respecting his space and responding to his needs, we can maintain his trust, which allows us to provide better care for him long-term.”

Atka’s surgical sutures have come loose, which is not uncommon in this procedure when performed in domestic hoof stock like cows or goats, but because he voluntarily participates in hoof care, CMZoo’s veterinary team and Atka’s surgeon have been able to monitor his foot closely, and are happy and comfortable with how it is progressing. Atka also actively participates in training to receive antibiotic injections and oral medication for any discomfort he might be experiencing.

“We want to give him the rest, pain medications and antibiotics he needs while limiting the number of times he has to go under anesthesia,” said Furnes. “So far, we haven’t needed to anesthetize him since his surgery. I’ve been so proud of him. He’s still coming right over to his training panel and presenting his hoof on the block so we can get a close look at his surgical site. He takes oral medications in an apple in the morning, and so far, he has let us give him all necessary injections of long-lasting antibiotic.”

Atka and his care team have worked to build that relationship through positive reinforcement husbandry training. Moose are rare in zoos, and are almost unheard of south of Colorado. Because they’re so rare in human care, there aren’t as many training protocols, so CMZoo has helped blaze the trail for moose training everywhere.

“When you go through a tough chapter like this with an animal, it reminds you of how important the relationship-building and training you’ve done in the past is,” said Furnes. “Ongoing maintenance training is always important, but when an animal’s recovery depends on it getting certain care, the relationship of trust and the language you have built together make the process less stressful and more successful for everyone – animals and humans.”

Atka is still healing and learning how to navigate on seven toes, instead of eight. Moose feet normally each have two toes that move independently to help the long-legged mountain mammals balance on rocky terrain. It is likely Atka will probably walk with an unusual gait for the rest of his life, since this necessary surgery has changed the structure of his foot – which is one-quarter of his foundation.

Animals are resilient, and Atka is adapting to his new foot. Keepers say that over the last four weeks of recovery, Atka has spent time lying down in comfy sand and shavings piles they’ve provided for him in his yard. He has been trotting, rubbing against trees, walking to his fence line to greet guests, enjoying fresh browse and wading in his pond. Guests might see Atka stumbling when he makes tight turns, favoring his one-toed foot, or curling it to rest it while he stands.

Atka has access to his barn and his yard for now, so visitors can stop by to wish him well in Rocky Mountain Wild. Atka’s team will continue to monitor him closely and make any adjustments to his medications, treatments or access to physical activity, with Atka’s best interests in mind.

Update: April 11, 2023
Atka, our 2-year-old Alaska moose, continues to recover from surgery on his front left hoof. Atka has been healing in his barn since his operation, and his care team has been happy with his participation in recovery care and rest. Now, his wound seems to be healthy enough that he got the veterinary go-ahead to stretch his long legs in the sunshine! Since yesterday morning, he has been exploring his yard and learning to navigate the terrain with just one toe on his front left foot.

Atka will take turns in his barn and out in his yard. Guests will notice Atka ‘curling’ that foot to rest it, working harder than usual to find his footing sometimes, and lying down to rest more frequently. The resilient young moose seems to be getting the hang of it already. He has been trotting, rubbing against trees, walking to his fence line to greet guests, enjoying fresh browse and wading in his pond between resting in his soft beds of sand and shavings. He even felt confident enough with his one-toed front hoof to successfully stand on three feet and use a back hoof to scratch the spots where he recently shed his antlers.

Atka’s surgical sutures have come loose, but because he voluntarily participates in hoof care, our veterinary team has been able to monitor his foot closely as it heals. Atka also receives voluntary antibiotic injections and oral medication for any discomfort he might be experiencing.

He’s making great strides with the support of his Rocky Mountain Wild and veterinary care team, but we’re not out of the woods just yet. Atka’s team will continue to monitor him closely and make any adjustments to his medications, treatments or access to physical activity, with Atka’s best interests in mind.

Next time you’re in Rocky Mountain Wild, stop by to say hello to Atka and wish him well as he continues his recovery. To read more about Atka’s surgery and other updates, keep scrolling down on this page.

Update: March 28, 2023 4:30 p.m. MT
Atka has been out of surgery for a few hours and seems to be doing well. The team is cautiously optimistic about the outcome of the procedure and Atka’s recovery from the anesthesia so far. Since he woke up, Atka’s care team has seen him stand for a short while and lie back down with good control. Now, he’s resting in his barn.

During his recovery, he may be in his barn for quiet time, but will also be given the option to move around as much as he’s comfortable. We are committed to Atka’s recovery and care as he steps into a life with seven toes. We will share updates on Atka periodically during his recovery process on the Zoo’s social media channels.

March 28, 2023
Cheyenne Mountain Zoo’s veterinary and animal care teams are partnering with Colorado State University Veterinary Teaching Hospital to remove a progressively problematic toe on Atka, CMZoo’s 2-year-old Alaska moose today, Tues., March 28, 2023.

The young male moose has experienced ongoing issues with his front left hoof and toe. Atka came to CMZoo at 8 weeks old in July 2020, after he was unfortunately orphaned in the wild in Alaska at around only six days old. Alaska Zoo cared for him until he was old enough to travel to CMZoo, where he has lived ever since.

Shortly after he arrived in 2020, his team discovered an abscess that had been growing in his front left toe and had become infected and needed treatment. Infections of this type in a young moose in the wild have the possibility of being fatal. Fortunately for Atka, the medical treatment his care team provided was successful, but the abscess created a hole which his body naturally filled with scar tissue. That changed the structure of his toe permanently, which gave Atka a unique gait with intermittent limping that didn’t always prove to be painful. Based on sensitivity tests during hoof care training, it seems the pain would come and go, and the presence of a limp didn’t always indicate he was in pain.

The team noticed him limping significantly and more consistently in February 2023. Atka voluntarily participates in hoof care, including a behavior for hoof x-rays. In February, the x-rays revealed significant bone degradation, compared to a November 2022 x-ray, in his front left outside toe, where the abscess was years before. After careful consideration, CMZoo’s veterinary, animal care and leadership teams decided together that a toe amputation was Atka’s best chance moving forward. In the meantime, Atka is receiving medication for pain.

“We know that animals can sometimes repair themselves better than we can, so we tend not to intervene too aggressively if we do not need to,” said Dr. Eric Klaphake, head veterinarian at CMZoo. “Our former moose, Tahoma, had a hoof issue that his body remedied naturally with the assistance of voluntary trained hoof trims, but Atka is experiencing progressive bone damage, which Tahoma did not. After monitoring and helping him with pain management, we’ve reached the point at which medical treatment and hoof care cannot stop further bone loss and the pain associated with it, and surgical correction is the best next step.”

The procedure will require Atka to go under anesthesia, which always has risk, but is riskier for a larger animal and for those classified as ruminants, like cows, that have multi-chambered stomachs. Removing the toe of an animal will inevitably alter its gait and cause it to rely more on other toes, hooves and limbs. The surgery team has performed similar and more complicated procedures successfully in the past, and CMZoo and CSU Veterinary Teaching Hospital have a long history of saving animals together. The team is cautiously optimistic that this procedure will get Atka on the path for a long and healthy life, but the surgery won’t likely completely correct his gait issues.

Planning for a young moose’s recovery involves embracing the unknown and preparing for whatever Atka decides to do. His team will work to keep his wound as clean and dry as possible for a feisty moose during a muddy season, and will balance his need to stretch his legs with the desire to keep him relatively calm as he recovers.

“Our Atka certainly hasn’t had the easiest life, but he has been resilient and determined since day one,” said Rebecca Zwicker, animal care manager in Rocky Mountain Wild. “After being orphaned and developing that infected abscess so young, we have seen him come through tough situations that would likely have been fatal without our support. We’ve helped him along this far, and we’re committed to helping him through this. We appreciate everyone rooting for him. Hopefully with the removal of this toe, he can put this whole abscess chapter behind him.”

The surgery is scheduled to take place today (Tues., March 28) at CMZoo. CMZoo will share updates on Atka periodically during his recovery process on the Zoo’s social media channels. Guests may not see Atka in his yard as often while he recovers.

Cheyenne Mountain Zoo’s conservation team recently returned from Panama. The trip highlighted CMZoo’s commitment to support ongoing research, education and breeding efforts for amphibians facing threats in the wild.

As part of the Panama Amphibian Rescue and Conservation (PARC) project, Cheyenne Mountain Zoo is actively involved in saving 12 top-priority species of Panamanian amphibians threatened by an infectious fungus called chytrid.

Thanks to the breed and release work done with Wyoming toads, CMZoo and its partners have played an important role in helping support PARC. While the CMZoo conservation team was in Panama, they shared valuable knowledge and provided a case study to help further release strategies and future planning. With the sharing of information and financial support, we are excited to help develop future release plans for PARC.

Amphibians worldwide are facing a mass extinction, and by visiting CMZoo, you’re supporting teams focused on finding solutions. This trip was funded by our Quarters for Conservation program. Every time you visit the Zoo, you are making a difference for Panama frogs and many other species around the world.

Looking at Jumbe [JOOM-bay], Cheyenne Mountain Zoo’s 2,800-pound Eastern black rhinoceros, visitors might assume that his demeanor matches his stature. On the contrary, according to Annie Dinwiddie, senior keeper in Encounter Africa who has worked with Jumbe for nine years.

“He’s actually really gentle,” said Dinwiddie. “I have worked with three black rhinos and two greater one-horned rhinos, and they’re all amazing, but there’s something special about Jumbe. He has this look where he tucks his upper lip in, and he makes eye contact with you, and you kind of just see each other quietly. You can tell he’s really observant.”

20-year-old Jumbe, who came to CMZoo in 2012, is an Eastern black rhino – a species of rhino native to Africa whose most distinguishable feature is its prehensile top lip. Eastern black rhinos’ ‘pointy’ lips help them strip leaves and bark from shrubs and trees in their native landscapes, whereas white rhinos’ flat lips help them most efficiently mow grass in their native African savannahs.

CMZoo guests who participate in Jumbe’s seasonal rhino feeding opportunities know his pointy lips well. At noon every day from March through October (weather permitting), guests can line up in Encounter Africa for a paid opportunity to hand-feed Jumbe. By extending his top lip to wrap it around the produce being offered, he gently accepts it – and usually leaves guests with a slobbery goodbye.

“To be that close to a rhino is a life-changing experience for most of our guests,” said Dinwiddie. “The slobber is part of the fun!”

Jumbe’s snack times also help guests make a direct connection with rhino conservation. The $10 cost to participate supports CMZoo’s black rhino and African elephant conservation partner, Tsavo Trust.

Being messy is a way of life for Jumbe, who loves a good mud wallow, which his keepers provide whether he’s inside or outside. He lies down on his side in the mud and rolls around until he has a thick coat of cool, protective mud all over. When he’s inside, he has the option of a hands-on mud bath, courtesy of his keepers.

“Jumbe loves to get a bath, and we happily oblige,” said Dinwiddie. “He walks into a stall where we have access to him from every angle through bollards. We reach in and scrub him with long brushes, warm water and vet-approved soap. After that, we get big handfuls of mud, and he walks over so we can rub it all over him. Sometimes he makes quiet happy little squeaks and really leans into the bollards so we can reach all of his favorite spots.”

Dinwiddie says he likes to get scrubbed between his toes and will even lift his feet up one at a time to tell them where to scrub. If a mud bath isn’t on the day’s agenda, you can bet daily scratches are. Jumbe also likes to be scratched behind his ears and in his armpits, which feel velvety soft compared to the rest of his body, which feels a bit like a cantaloupe.

“Jumbe consistently chooses to spend time with people when it’s an option, and we always have plenty of activities for him to choose to do,” said Dinwiddie. “He’ll be enthusiastically tossing a huge barrel around, or stacking huge tires on his horns, or mud wallowing, but if he sees us, he almost always comes over to see what we’re doing.”

That doesn’t mean he’s longing for attention, though. Jumbe, like the preference of wild male black rhinos, is solitary at the Zoo. Because his genetics are well represented in the assurance population of black rhinos, it’s highly unlikely he’ll be recommended to breed. Apart from his keepers, he seems to enjoy socializing with his elephant neighbors.

“We have seen him and Jambo, one of our six African elephants, standing on either side of bollards next to each other,” said Dinwiddie. “Jambo will smell Jumbe with her trunk, and Jumbe will nudge her with his horn, and they just seem to be enjoying the tactile interaction for a few minutes. But, we don’t think he would enjoy sharing the space with the elephants. He still enjoys having his own space and being able to interact when he chooses to.”

Eastern black rhinos are one of five remaining species of rhinoceros, along with two species native to Indonesia, the Javan and Sumatran rhinos, which each have only 70 or fewer wild individuals remaining. The greater one-horned rhino is native to India and Nepal, with around 4,000 wild individuals remaining. White rhinos are native to Africa and have around 15,000 in the wild. Eastern black rhinos, like Jumbe, are native to Africa with around 6,000 individuals in the wild.

“For most people in the U.S., he’s the only rhino they’ll ever see,” said Dinwiddie. “Even people who visit Africa multiple times aren’t guaranteed to see them, so we’re very aware of what a special opportunity it is to work with or meet Jumbe.”

Tsavo Trust works to protect the last of the big tuskers, which are African elephants with tusks weighing more than 100 pounds, and Eastern black rhinos, in Tsavo National Park, in Kenya. Funds raised through Jumbe’s snack times and scheduled daily seasonal elephant feedings help pay for pilot hours of frontline aerial surveillance that protects rhinos and elephants from poachers seeking their ivory and horns.

Along with funding from the Kratt Family Foundation, CMZoo guests’ support has helped build permanent housing that allows staff to live on the land where these endangered giants live. It has funded the construction of a vehicle maintenance building and special projects in local communities.

“By feeding Jumbe, you’re making a connection with him, and you’re directly supporting his wild counterparts,” said Dinwiddie. “That’s why we’re here, and Jumbe can inspire guests to care for wild rhinos better than any of the rest of us can.”

One way to prevent further destruction of Indonesian habitats where rhinos live is by supporting companies that use sustainable palm oil, rather than using unsustainable palm oil production. Download the free WAZA PalmOil Scan app, launched by CMZoo, Auckland Zoo and Chester Zoo, under the direction of the World Association of Zoos and Aquariums (WAZA) last summer, and scan products before purchasing them. (Learn more and download the app at cmzoo.org/palmoil.)

Jumbe’s attentive gentle nature makes him an excellent voluntary training participant. He participates in target training, positioning his body in different ways so keepers can get closer looks at different parts of him, x-rays, presenting his horn, injection training and blood draws.

“One of the first things I trained with him on was a blood draw,” said Dinwiddie. “He quickly picked up what we were asking him to do. He presents one of his front legs so we can draw blood from a vein where his skin isn’t as thick. He has been such an exemplary student that we’ve been able to share our training methods with other people who care for rhinos. We communicate with him, and he communicates with us throughout the sessions.”

During blood draw training, Jumbe puts his foot on a black mark on the ground. When he is ready to move on to something else, he knows he can move his foot off that mark, and his trainers will end the training session. His favorite training rewards, or reinforcers as they’re known in the zoo profession, are apple, banana and carrots dipped in peanut butter and jelly, or blueberry bagels – all in vet-approved treat-sized amounts.

“He’s truly amazing, and I just can’t imagine a world without rhinos,” said Dinwiddie. “Rhino and elephant conservation can be complicated. It can be de-motivating because the problem can feel so big that it’s overwhelming, but all of us can make a difference. People can directly support Tsavo Trust by visiting our Zoo, and we can teach them not to purchase rhino products. The leading cause of decline for all five rhino species is horn poaching and habitat loss. We have to stop the demand for rhino horns by educating people that rhino horns don’t contain medicinal materials. Their horns are made of keratin, and are literally no different than a fingernail.”

Next time you’re at CMZoo, stop by Encounter Africa to wave hello to Jumbe and plan your day to line up for a scheduled seasonal feeding opportunity. Even if you don’t make it to feed Jumbe, you’re supporting black rhino conservation by visiting CMZoo. 75¢ from every admission supports local and worldwide conservation efforts through our Quarters for Conservation program.

Our new shipping container farm recently produced its first crop!

The container is equipped with the latest hydroponic vertical growing technology, including blue and red LED grow lights with specialized wavelengths for leafy green production. In this first harvest, the CMZoo horticulture team looked for uniform shape and size in each plant, signs of disease or deficiency, any dead or damaged leaves, and ways to best transplant the next crop.

Through surveying the weight, time, and resources of this first crop, the horticulture team was happy with the success of the beautiful harvest and is already fine-tuning the farm in preparation for the next harvest.

This harvest is the first of many tests of the fully automated computer system that tells the CMZoo horticulture team the recipe of light, water, nutrient and spacing needs for the specific plant species. After a period of testing, the goal is to add more shipping container farms sourcing 50 percent of the lettuce for the giraffe feeding experience. An even longer-term goal is to grow 80 percent of lettuce for Zoo animals in farms like this one.

The next time you visit CMZoo and feed our giraffe herd, you might be feeding them lettuce straight out of our own farm!

Five Rocky Mountain goats call CMZoo home. Twinkie (17), Yazhi (12), Albert (8), Lena (3) and Blanca (9 months) make up the herd seen high up in their customized habitat made up of cascading rock formations. This steep habitat mimics the terrain Rocky Mountain goats experience in the wild.

Their unique hooves have two toes with a soft center that acts as a kind of climbing shoe. Keepers help our goats get the best grip on the rocks through important voluntary hoof care training.

Our goats also participate in target training and scale training. When keepers ask the goats to touch or move to a target, they are rewarded with their favorite treats. This training allows keepers to weigh them on a scale, administer vaccines or other medications, and check their hoofs for overgrowth or foreign objects.

Next time you visit CMZoo, stop by the Rocky Mountain goat exhibit and watch members of the herd scale rocks with their nimble hooves!

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!

Cheyenne Mountain Zoo is preparing for the arrival of a female Amur tiger, Mila [MEE-luh], in early March and the departure of a male African lion, Boma [BOH-muh], in late March. The two moves support their respective Species Survival Plans, but aren’t necessarily immediate breeding recommendations. Organizations accredited by the Association of Zoos and Aquariums (AZA) often work together, like this, to provide the best homes available as animals mature and develop different needs, like additional space or new social opportunities.

Mila, who will turn two on May 1, will travel to CMZoo from Toronto Zoo, where she was born and has lived with her mother, Mazy, until recently. Tigers are typically solitary in the wild, so Mila is prime to embrace the world as an independent young adult tiger, but she’s still a little young to become a mom herself. CMZoo’s tiger habitat in Asian Highlands has plenty of space to make a home for Mila.

Chewy, CMZoo’s nearly 8-year-old male Amur tiger, and Mila will certainly be aware of each other’s presence in the tiger building, where they’ll have separate dens, or in the yards they will take turns exploring. However, there are no immediate plans to introduce the tigers.

For animal transfers, keeper teams from both zoos typically work together to make animal moves as low stress as possible for all involved. They share information about an animal’s favorite treats, enrichment items, trained behaviors, den setups, behavioral tendencies and more. This helps the animal’s new care team provide the best possible welfare once the animal arrives.

“This is Mila’s first-ever move, so we want to make it as positive an experience as possible for her,” said Rebecca Zwicker, animal care manager in Asian Highlands. “She has been Toronto’s sweetheart, so we’re happy to welcome her to our community where we know she’ll be equally admired and respected with a life of choice, opportunity and care.”

Mila’s team will follow her lead as she learns the new faces, spaces and smells at CMZoo. Once she arrives, they’ll focus on building trusting relationships with her through training, enrichment, positive reinforcement and lots of her favorite activities and meals.

“There’s no need to rush things,” said Zwicker. “We’ll be excited to share her with guests as soon as Mila shows us she’s ready.”

Unlike tigers, African lions are social animals. As they mature, they sometimes outgrow their family units. Seven-year-old Boma, who was born at CMZoo in 2015 and has been living with his brother Aslan for the last several years, is showing signs he’s ready for his own pride.

Boma is moving to another AZA-accredited organization in California, where he will be the only male in the pride. Because Boma’s genetics are well represented in the assurance population of African lions in human care, this move is unlikely to result in a breeding recommendation.

“A huge part of our role as keepers is to provide the best possible environments for our animals,” said Rachael Hahn, African Rift Valley senior lead keeper. “When you see an animal is telling you it’s time for something new, we embrace the fact that there’s a reward for them that far outweighs the risk. Of course, it’s hard to say goodbye when an animal moves on, but we really think this new place and pride are going to be perfect for him.”

To prepare him for his road trip, the African Rift Valley animal care team has been familiarizing Boma with his travel crate and making sure he’s in tip-top shape to make the trip. Boma’s keepers at CMZoo have been in contact with his new care team in California, so they can welcome Boma and be aware of his tendencies, preferences and motivators.

“Boma is probably our most confident lion,” said Hahn. “I can just see him strutting into his new home with his impressive presence and quickly winning the hearts of the team and the respect of his new pride.”

With Boma leaving, African Rift Valley keepers are working to provide Aslan with social opportunities, too. Four African lions will remain at CMZoo: the patriarch, Abuto, the aging matriarch, Lomela, their daughter, Elsa, and their son, Aslan. The long-term plan is for Elsa and Aslan to share space, with interbreeding preventions in place, and for Lomela and Abuto to share space. The introduction plan will be ongoing, so guests may see groups of two or three lions together as the care team works to support the changes in the pride.

Guests who want to wish Boma well on his new adventure should do so before Mon., March 27. CMZoo will provide social media updates on Mila’s arrival, including when guests might be able to see her in Asian Highlands, as she settles in.
