Ring-tailed lemur half-brothers, Elo and Maky, are preparing for a big adventure! They’ll soon join a bachelor group of nine ring-tailed lemurs at Brevard Zoo – an accredited member of the Association of Zoos and Aquariums (AZA) in Melbourne, Florida.

Ring-tailed lemurs are endangered, and wild populations are decreasing, according to the International Union for the Conservancy of Nature (IUCN) Red List. This move is in support of the Ring-Tailed Lemur Species Survival Plan (SSP), which manages assurance populations in human care to make breeding recommendations and achieve the highest possible genetic diversity among animals cared for by AZA-accredited organizations that support SSPs, like CMZoo. Rogue and Allagash, the two moms on Lemur Island, have both been recommended to breed again with Hercules.

“This is bittersweet, because of course we will miss Maky and Elo, but it’s an exciting opportunity to bring more of this endangered species into the world,” said Erin Henninger, animal keeper in Water’s Edge: Africa. “That’s why we exist as an organization – to save species and to inspire people to protect wildlife and wild places. Ring-tailed lemur babies are really good at inspiring people. It’s also an opportunity for their sister, Anja, who will hopefully be a mom someday, to observe her mom and aunt giving birth and raising young. She will likely help raise her future little brothers and sisters.”

In preparation for this move, the lemurs’ care team prioritized crate training. The goal is to make the lemurs comfortable entering, exiting and spending time in their travel crates, since they’ll be wide awake for their flight. The boys have mastered crate training, and even know how to close the crate door behind them.

They have also learned a number of foundational voluntary behaviors, like shifting (moving to a location when asked), targeting (moving to a specific location and touching a target stick, so keepers can get a closer look at them), and injection training.

“We’ll work with their future keepers to relay their training knowledge, individual preferences – like favorite training treats – and behavior histories, so we can all best support them as they settle in,” said Henninger. “Both boys are really smart and eager to train, and they have good social skills, so we’re looking forward to seeing them embrace this next chapter in their development as young adults.”

Guests who want to visit Maky and Elo before their departure should plan a trip to the Zoo before mid-October. Stay tuned for more updates on Allagash, Anja, Rogue and Hercules by following CMZoo’s social channels!

About Cheyenne Mountain Zoo

Cheyenne Mountain Zoological Society was founded in 1926. Today, Cheyenne Mountain Zoo, America’s mountain Zoo, offers comprehensive education programs, exciting conservation efforts and truly fantastic animal experiences. In 2023, Cheyenne Mountain Zoo was voted #4 Best Zoo in North America and CMZoo’s Rocky Mountain Wild was named #2 Best Zoo Exhibit in North America by USA TODAY 10Best Readers’ Choice Awards. It is Cheyenne Mountain Zoo’s goal to help guests fall in love with animals and nature, and take action to protect them. Since 2008, CMZoo’s Quarters for Conservation program has raised more than $4.5 million dedicated to frontline conservation efforts around the world. Of the 238 zoos and aquariums accredited by the Association of Zoos and Aquariums (AZA), Cheyenne Mountain Zoo is one of just a few operating without tax support. Cheyenne Mountain Zoo depends on admissions, membership dues, special event attendance and donations for funding.

Elo and Anja, Cheyenne Mountain Zoo’s vivacious ring-tailed lemur twins, turn two years old on Tues., July 11! They may be the youngest residents on Lemur Island, but they have leadership in their lineage, thanks to their respect-commanding mother, Allagash, and the fascinating hierarchy of lemurs.

“Allagash is kind of the queen of Lemur Island,” said Courtney Rogers, senior keeper in Water’s Edge: Africa. “So, it’s not too far-fetched to say her kids would be the prince and princess. Female lemurs typically sit at the top of the hierarchy in lemur groups. Allagash and her sister Rogue have always outranked Hercules, their male mate and the twins’ father. Now that the island youngsters are getting bigger, it’s pretty clear that Anja is embracing her role as second-in-command.”

When it’s dinner time, Allagash eats first and allows only her kids to sit close enough to join her for the first-round snacks. Anja will help her mom chase the others away if they feel like they aren’t getting the best possible food options, best places to sunbathe, most interesting enrichment items or enough space to themselves. Of course, keepers make sure there’s plenty to go around to the whole group. Elo, Anja’s male twin, and their half-brother Maky, seem to mirror their dad, Hercules’ personality, and go with the flow. Rogue is more laid back than Allagash, which works for their group dynamic.

“Our group has its hierarchy well established, and they are so sweet with each other,” said Rogers. “All six of them will pile into the same hammock and wrap their tails around each other to snooze peacefully, or sit in a big line to groom each other, which is a sign of a tightly bonded group. The half-siblings, Elo, Anja and Maky, love to chase, leap and wrestle around together.”

Anja, who is the smallest lemur in the group, has a lot of heart. She is usually right at Hercules’ side when he calls the family together with a contact “howl”, and is often the first to add her vocal talent to his. Ring-tailed lemurs use over two dozen unique vocalizations, so Anja and Elo have been practicing their calls to communicate with family members. They are both very observant and have a great vantage point from high in the treetops, so they’ll let everyone know if they see anything that might be out of the ordinary. Maky, Allagash, Rogue, and Hercules come to investigate and join in, and practicing a synchronized family chorus helps their bond grow even stronger. Then, it’s back to napping, snacking and playing.

“They love turning our ideas for enrichment into even-better activities,” said Rogers. “We got them a knotted rope hammock recently and Elo, Anja, and Maky had such a great time jumping in and out that it started looking more like a vertical mesh ladder than a hammock. They quickly invented a new game, and we watched them leap to the top of the newly-imagined ladder and somersault back down over and over again. It’s always a fun surprise to see how the lemurs are going to interact with their surroundings. They have so much energy and they’re great innovators!”

The high-energy, high-climbing, beautifully bonded family will surely keep all party goers in good spirits as the whole Water’s Edge: Africa family celebrates the twins.

Mark your calendars for 10 a.m. to noon on Tues., July 11, and get advance e-tickets to join in the festivities. The birthday party will be at the hippo pool in Water’s Edge: Africa, where our partners at Children’s Hospital Colorado, will bring a very special pair of 2-year-old twins who will celebrate their own birthday!

In the wild, animals spend a lot of time and energy foraging or hunting for food. Feeding our animals seems like a pretty fundamental task of animal care, but it’s more complicated than one might think. Just like our partners at Children’s Hospital Colorado talk about foods that can have calming effects for kids, we work to present our animals’ special diets in ways that nourish their bodies and support their natural instincts.

Wild animals have to solve problems and exert physical energy to feed themselves, which is good for their physical fitness and their mental well-being. Here at the Zoo, we provide opportunities for our animals to fulfill their instinctive hunting or foraging behaviors by hanging food high, or burying it, or placing it in a puzzle feeder that requires focus and dexterity to reach.

“We work hard to create environments and provide daily activities that enrich our animals’ lives, but some people might not immediately recognize that their meals are another opportunity for enrichment,” said Rachael Hahn, lead keeper in African Rift Valley. “I get to work with one of the most iconic hunting species out there: African lions. In the wild and in human care, African lions typically sleep 20 to 22 hours a day, but when they’re active, they’re certainly making up for lost time. They’re unbelievably smart, incredibly strong and as confident as they come.”

Hahn and her team in African Rift Valley make meal time mentally and physically stimulating for Abuto, the 10-year-old pride patriarch; Lomela, 14-year-old matriarch; Elsa, their 6-year-old daughter; and Boma and Aslan, their 6-year-old sons. In addition to scattering food throughout their large yard, the team hangs big pieces of meat up high in a tree for our African lions, so they have to climb up and drag it down, like they would do with some prey in the wild.

“We have been doing this for a couple of years where guests can see it, and the lions seem to really enjoy working for their rewards,” said Hahn. “We also put meat inside some of their giant plastic boomer balls, and have seen the lions ‘playing’ more often, even when food isn’t involved. I’ve seen Lomela, who’s nearly 15, playing with toys like she’s a kitten again. Since making this addition to their routine, we’ve seen them exhibiting calmer behaviors at other times of the day, which is a great indication that they’re mentally fulfilled thanks to these additional opportunities to solve problems.”

Water’s Edge: Africa keepers provide meal-driven enrichment opportunities for the high-energy, intelligent residents of Lemur Island, too. The ring-tailed lemurs at CMZoo get the chance to frequently dine-and-dash, because their meals encourage them to, and the family’s diets are rarely presented in the same way.

“Lemurs are one of few primate species that forage from the ground, up high in the trees, and everywhere in between,” said Al Carrier, Water’s Edge: Africa keeper. “They’re super smart, so we get creative finding new places to stash their food. It’s kind of like an Easter egg hunt every time we place their meals on Lemur Island for them, and it’s fun to watch them scurry and leap around, finding their delicious rewards.”

Keepers also use puzzle feeders that the lemurs can use their long fingers and impressive fine motor skills to retrieve food from. They hang food in spheres that require the lemurs to stretch, climb and leap to reach. They also get seasonal delicacies, like browse.

“In the wild, lemurs eat tree leaves and buds, so we provide that as often as possible for our lemurs,” said Carrier. “We bring in fresh browse – otherwise known as tree branches – from our community and sometimes from our shipping container farm, here at the Zoo. They love to search for the buds on those branches in the spring because they make a nice sweet treat.”

Keepers recently noticed Anja, a 5-month-old ring-tailed lemur pup, appeared to be consistently clenching her hands. The extremely energetic little lemur didn’t appear to be having any mobility issues as a result, but because lemurs use their hands to grip trees and move around, keepers wanted to keep a close eye on her. She was keeping up with her twin brother, Elo, and older half-brother, Maky, just fine.

“Once Anja gained independence and wasn’t spending most of her time clinging to her mom, we noticed she wasn’t opening her hands all the way,” said Grace Sullivan, Water’s Edge: Africa keeper. “She’s constantly leaping around with her brothers, so we’re not concerned about her well-being, but if there’s something we can do now to help her avoid any potential future limitations, of course we want to do that.”

Water’s Edge: Africa keepers and CMZoo’s veterinary staff teamed up to check on little Anja, and didn’t see any injuries or unusual bone structure. There’s no formal diagnosis at this point, but it appears she has tight ligaments.

After consulting with a veterinary sports medicine and rehabilitation specialist, her team built a physical therapy routine for Anja. The routine has similar goals as the exercises prescribed by physical therapists at Children’s Hospital Colorado’s Sports Medicine Center, partners of CMZoo.

“During her therapy, we ask Anja to hold onto a wooden pole and then we turn the pole slightly so her fingers open up,” said Sullivan. “She’s really smart, and she loves the training rewards she receives during the sessions, so she’s usually eager to participate.”

Anja doesn’t appear to experience discomfort during these training sessions and keepers have seen some improvement in her range of motion since starting the therapy in mid-November. Keepers do this behavior with Anja three times a week.

In addition to training, the team added some obstacles to Lemur Island that encourage her to stretch those tight ligaments as she moves around throughout the day. There’s a series of bamboo poles attached perpendicularly to another pole, which the lemurs have all enjoyed exploring. The poles are a wider circumference than other climbing opportunities on Lemur Island, so Anja’s fingers get a good stretch while she navigates, as has fun at the same time.

“The lemurs also share a new rope hammock made of thick ropes set far apart,” said Sullivan. “It’s enriching for all of the lemurs to explore these new items, but we’re especially happy to see Anja using them successfully.”

The team will continue working with Anja to gain flexibility in her fingers.

“We talk about how there’s always a balance when you’re addressing any potential struggles an animal might face,” said Sullivan. “We want to make sure Anja is okay, but we don’t want to go too far with treatments or diagnostics if she can clearly do all of the lemur things she needs to do with her hands as they are. Her hands might just be another thing that make this little one so special, in the long run. For now, we’re seeing the exercises help, so we’ll keep doing them.”

The newest residents of Water’s Edge: Africa, Allagash’s twin lemur pups, have names! The three-month-old ring-tailed lemurs’ keepers have named the female youngster Anja (ON’-juh) and her brother Elo (EE-low).

“We picked the name Anja to honor a forest reserve in Madagascar where you can find the highest concentration of ring-tailed lemurs in the world,” said Erin Henninger, Water’s Edge: Africa keeper. “Ring-tailed lemurs are endangered in the wild, and we hope her name will help us bring awareness about lemur conservation, and what people can do at home to help save Anja’s wild counterparts.”

Anja’s brother, Elo, is also named for lemur conservation. In Malagasy, the native language in Madagascar, elo means umbrella. Ring-tailed lemurs are an umbrella species, which means conservation efforts for their species typically help protect the other species sharing their ecosystem.

In the wild, lemurs are facing extinction due to habitat loss and a growing desire to own lemurs as pets. By purchasing wood and paper products that have the Forest Stewardship Council’s (FSC) label, lemur lovers can rest assured they’re not contributing to unsustainable logging practices that impact many species’ native forests. Although lemurs are adorable, they’re best cared for by organizations that know how to house this very social species in groups, with specialized care and programs aiming to save this species in the wild. Visiting lemurs at organizations accredited by the Association of Zoos and Aquariums is a great way to connect with lemurs without negatively impacting their wild populations.

Anja and Elo, along with their cousin, Maky, their mom, Allagash, their dad, Hercules, and their aunt, Rogue, are doing a superb job of helping CMZoo guests fall in love with their loveable species. The Zoo’s hope is that by making connections with our conspiracy (a group of lemurs), guests will take action to protect them in the wild.

“Anja and Elo are getting more and more independent every day,” said Henninger. “They are bundles of energy and it’s not unusual to see them zooming around the island with their six-month-old cousin, Maky. They like to jump and run around their trees and still jump on their mom, Allagash, who is really patient with their adorable antics. We’ve also seen them playfully sneak up behind their dad, Hercules, to pull on his dangling striped tail and then scurry away quickly, like they’re ringing a doorbell and running away. He knows it’s them and doesn’t seem to mind their little game.”

When they’re not pouncing from limb to limb or climbing on each other and their relatives, Anja and Elo can often be seen in a lemur cuddle puddle. Between all that zooming, naps are important. The six lemurs like to pile up in one hammock for an extra snuggly sleep. The twins have also started ‘sun worshipping’ like their older relatives.

“The lemurs love to climb up to the very top of the trees on Lemur Island in the morning to sun themselves,” said Henninger. “They face the sun and sit with their arms open, relaxed on their knees, with their paws palm-up, like a yoga pose. We’ve seen the twins mirroring the behavior in a very exaggerated pose with both of their arms extended way above their heads. It’s pretty cute to see them embracing those instincts, but not quite perfecting the pose just yet.”

The twins can be difficult to tell apart, but keepers say Anja’s forehead markings make an inverted widow’s peak, like her mom, Allagash. Elo’s dark fur above his eyes is more like a straight-across bowl cut, like his aunt, Rogue. Elo has longer tufts of fur on his ears than his sister. Anja is smaller than her brother and her tail isn’t as fluffy as Elo’s. Anja’s gray fur on her body is lighter than Elo’s.

“Both babies have bold personalities, but Anja seems more outgoing with keepers and has been more independent than Elo from a young age,” said Henninger. “He’s more of a mama’s boy, which is sweet. When they were still hanging on their mom all the time, Anja more often ventured off of mom to approach the rest of the group.”

Guests can see all six lemurs on their lush, green island in the middle of the hippo pool, indoors and outside, right away. Next time you’re at Water’s Edge: Africa, look out for the fast-moving twins and their family, bouncing around or enjoying a cuddle together.

It’s officially back-to-school season. While our partner, Children’s Hospital Colorado, helps parents prepare for the academic year ahead, Water’s Edge: Africa keepers are helping 4-month-old ring-tailed lemur, Maky [MAH-kee], take his first steps toward training!
Many animals at the Zoo participate in voluntary training, which allows them to choose to participate in their own health care and other husbandry behaviors for their well-being. One of the first steps in training is building a trusting relationship between the animal and its keeper team.

“Developing a relationship with a young animal is one thing, but the real test is our relationships with their mothers when we need to work with them,” said Phil Waugh, lead keeper in Water’s Edge: Africa. “The fact that our ring-tailed lemur moms are comfortable with us being close to and even touching their babies is a huge signal that they trust us – not only with their safety, but with their babies’ safety.”

Maky’s mom, Rogue, calmly sits by, snacking on raspberries, as the Water’s Edge team comes onto Lemur Island to see if Maky wants to train. The young lemur is clearly excited by all of the activity – and snacks. He may be young, but he has mastered the art of speed leaping. He jumps quickly from one branch to another to make it over to the keepers, even beating his dad, Hercules, for top positioning closest to his trainer, Erin.

“Maky is incredibly confident with his team, and he’s full of energy,” said Waugh. “He’s young, so his training will start with learning to focus on one keeper and one task at a time. He’s quite a rambunctious little student, so it’s endearing to see him really harnessing that focus to participate with his keeper team.”

Little Maky is also learning to accept voluntary injections. The team will start by simply bringing a syringe without a needle near him, so he can see what it looks like. Then, they’ll touch him with the syringe, then add a blunted needle until he’s totally comfortable with it. Injection training is often a top priority for new or young animals, since it helps them receive vaccinations they need with as little stress as possible.

CMZoo’s three adult lemurs, Allagash, Hercules and Rogue, are injection trained, too. They have also learned more complicated behaviors, like voluntarily loading into a transport crate for low-stress moves from Lemur Island to the vet clinic, for example. They continue to learn, too! They’re working on presenting different parts of their bodies for keepers to touch and check for possible wounds or other issues.

“Allagash, who gave birth to twins in July, has also shown us she’s comfortable with us getting close to her babies,” said Waugh. “When we ask her to stretch up or show us her belly, she’s happy to do it. It helps us do visual checks on her and the twins, while they’re still clinging to her back and chest most of the time.”

Maky spends very little time on his mom’s back anymore, but still seems to like sitting next to her for the lemurs’ daily morning sunbathing sessions. We hope you all do well as you head back to school, and that you get lots of rewards for your training, just like Maky!
