Saying Goodbye to Ngozi

It is with heavy hearts that we announce the passing of Ngozi, our beloved spotted hyena, on Monday, May 26. Ngozi moved to DZCA the day after her fifth birthday and was the last original resident of Benson Predator Ridge. Earlier this month, Ngozi celebrated her 26th birthday, making her the oldest spotted hyena in the Association of Zoos and Aquariums.  

Ngozi has been under successful long-term treatment for spondylosis, a degenerative spinal condition affecting the discs, ligaments, and joints. On Monday, our Animal Care Specialists observed a rapid decline in her hindleg mobility which would negatively impact her quality of life. Our dedicated Animal Care and Veterinary Medicine team made the difficult decision to humanely euthanize her to relieve her suffering. This decision did not come lightly and was made due to the progression of her condition and the significant effect it was having on her ability to navigate her habitat.

Ngozi passed peacefully on Monday afternoon, surrounded by those who loved and cared for her. A full postmortem examination will be performed by our Veterinary Pathologist to fully understand Ngozi’s condition and help support the scientific understanding of spotted hyenas around the world.

Remembering a Remarkable Resident

Like every loss we experience at the Zoo, saying goodbye is difficult and Ngozi’s passing has been especially hard on those who cared for her over the years. Members of our Carnivore Team have shared what working with Ngozi has meant to them:  

“Ngozi was a legend, the kind people tell stories about long after they are gone. In her 21 years at Predator Ridge, she inspired and wowed millions of guests and helped positively change the perception of hyenas. After meeting her, we would often hear people say they didn’t realize hyenas were so cute, or so smart. In her time here she made an immeasurable impact on countless animal care staff, her loss is one that is felt across the country. She was our rock in the building for many years, always being able to rely on Ngozi for demonstrations, tours, to be the calming presence for new animals, and to help new animal care specialists gain confidence in themselves. One of the things I will miss the most is when Ngozi would be in the side yard by the zebras, in the morning she would see you come in and she would jump up, get excited and run as fast as she could inside to meet you at the window in the kitchen for a good morning snack. No one could resist giving Ngozi a few extra good morning snacks. Predator Ridge had never seen a day without Ngozi, and it will never be the same after her.” –  Animal Care Specialist Jordan S.  

“I only had the honor of taking care of Ngozi for a little over three years, but I will talk about her forever. She is such a powerful, strong-willed, smart, and hilarious girl. She was often hard to find sleeping in the sun of her favorite yard, but I think she liked it that way. And when you did see her, she was easily identified by her sweet ‘eyebrows.’ I can’t put into words how much you meant to everyone who passed through this building for the last 21 years, Ngozi. But I know you will be missed for a very long time. Thank you for sharing your life with us all these years.” – Animal Care Specialist Amelia J. 

“It was an absolute honor to be one of Ngozi’s caretakers. She had so much spunk and always kept us on our toes. Her intelligence and strength never ceased to amaze me. Ngozi loved to play in the water and redecorate her exhibit with sticks and logs. She continued to learn new things in her older years and we could always count on her to be the star of our animal demonstrations. We are losing a true queen and she will be greatly missed.” – Animal Care Specialist Karli N.

“I loved working with Ngozi over the years—she never failed to make me smile when I looked at her sweet fuzzy face or with how quickly and cleverly she solved things. She did everything in her own unique way, unlike any other hyena, and that is what made her so special.  Ngozi was incredibly playful with enrichment. It was always exciting to give her something new because she made it fun for us too. Her curiosity pushed us to be more creative, always looking for new ways to challenge and engage her.  One memory that always makes me laugh is when we gave her a puzzle cube filled with food. Instead of carefully figuring out how each door opened, she used her strength and smarts to throw it across the room until a door opened and she could easily get the meat. It wasn’t the expected solution, but it was effective—and very Ngozi.  Over her years at DZCA, Ngozi didn’t just bring us joy—she helped train many of us on how to work with spotted hyenas. She left a lasting impression, and it’s no surprise that former caretakers still check in on her. She was deeply loved and cared for.” – Assistant Curator of Carnivores Katelyn S.

Ngozi’s legacy lives on through her seven offspring and the countless human lives she touched along the way. She will be dearly missed by all those who had the pleasure of knowing and caring for her.


All Paws on Deck: Collaborative Veterinary Care for Our African Wild Dog Pack  

At Denver Zoo Conservation Alliance, animal well-being is at the heart of everything we do. On May 7, our Helen and Arthur E. Johnson Animal Hospital welcomed some very special patients: our Endangered African wild dog pack Theodore (Teddy) Roosevelt, David (Dave) Livingstone, and Nigel. These eight-year-old brothers came in for their biannual wellness exams, a critical part of our commitment to world-class animal care. 

Specialized Care With Expert Partners 

As wild dogs age, they’re at higher risk for heart issues and dental disease. That’s why we collaborated with partners, Veterinary Cardiologist Dr. Brian Scansen and Veterinary Dentist Dr. Naomi Hoyer, both from Colorado State University’s College of Veterinary Medicine to utilize their expertise while managing these specialized procedures.  

With the help from Dr. Scansen, Dr. Hoyer and their teams, we were able to carefully evaluate each dog’s heart and teeth, while our DZCA Veterinary Medicine team led the anesthesia, overall wellness checks, treatments and vaccines, in addition to completing CT scans.  

We also looked at Dave’s dry eyes and assessed Nigel’s lower back to make sure our tripod pup remains in good shape. 

Collaboration in Action 

Coordinating this type of multi-disciplinary exam takes time and teamwork. Over the course of a month, our dedicated Animal Care Specialists, Veterinary Medicine staff, and CSU partners worked together to plan every detail—from the order of anesthesia to transportation and recovery protocols. 

Thanks to that preparation, the process was smooth, efficient, and most importantly, safe and stress-free for the animals. 

Understanding the Unique Needs of Our Pack 

African wild dogs are highly social animals with a strict hierarchy. That means veterinary care requires careful planning to protect their pack dynamics. To minimize stress, all three wild dogs were anesthetized simultaneously. It was equally important that they woke up in the correct order—Teddy first, as pack leader, followed by Dave and Nigel—to preserve their social structure. 

This attention to behavioral nuance ensures the health of the animals not just physically, but emotionally and socially as well. 

Conservation Through Compassionate Care 

Excellent animal care goes hand-in-hand with wildlife conservation. By providing specialized, proactive medical treatment, we help ensure the longevity and quality of life for the animals in our care. That helps supports broader conservation goals for Endangered species like our wild dogs, who are part of the Association of Zoos and Aquariums’ Species Survival Plan.

At DZCA, collaboration between expert teams and external partners allows us to deliver the highest standard of care and contributes meaningfully to the global effort to protect wildlife.

BABY BULLETIN: Fluffy New Additions to DZCA 

New Chicks on the Block 

For the first time at Denver Zoo Conservation Alliance (DZCA), five scaly-sided merganser chicks have hatched—an adorable win for their Endangered species! The proud parents are Jericho Chris, an almost four-year-old female, and Andrew Demetrius, a three-year-old male. Both adults live in our Primate Panorama Forest Aviary, where guests can visit and learn more about this rare duck species. 

Scaly-sided Mergansers are known for their diving ability, which allows them to plunge underwater to catch food like small fish, aquatic insects, and crustaceans. Native to the forests and wetlands of China, Korea, Russia, Japan, Thailand, Myanmar, and Taiwan, these ducks are facing growing threats due to habitat loss, pollution, and illegal hunting. 

They are currently listed as Endangered on the IUCN Red List, with only 2,400–4,500 individuals remaining in the wild.  

A Strong Start Behind the Scenes 

The chicks were incubated and hatched in our Avian Propagation Center (APC), where our dedicated Animal Care team is now supporting their early development. Even at just a few days old, the chicks are already swimming and diving for food on their own, which is an incredible display of natural behavior and a positive sign for their growth. 

To ensure these chicks get the best start, our team is feeding, monitoring, and even teaching swimming lessons to prepare them for life alongside their parents. Once they’re strong, confident divers, they’ll join mom and dad in the Primate Panorama Forest Aviary. 

Inside the Avian Propagation Center 

Did you know DZCA is home to one of the largest Avian Propagation Centers in the country? Located behind the scenes, this 14,000-square-foot, state-of-the-art facility houses and breeds many endangered and critically endangered birds in an effort to steward species conservation. From hand-rearing chicks to supporting breeding and incubation, the APC plays a crucial role in helping sensitive bird species thrive. 

Each new chick represents a hopeful milestone for the species and a testament to what’s possible when conservation, science, and care come together. 

A Hopeful Future for a Rare Species 

These hatchings are part of an Association of Zoos and Aquariums Species Survival Plan (SSP). SSPs are collaborative programs among accredited zoos to breed and manage threatened species and ensure genetically healthy and diverse populations. We’re proud to support this important work through our continued participation in SSPs.

Collaborative Cancer Care for African Penguin, Keni

At Denver Zoo Conservation Alliance (DZCA), every animal receives expert, individualized care, no matter how complex their needs may be. Keni, a 16-year-old member of our Critically Endangered African penguin flock, has been receiving life-saving cancer treatment thanks to a powerful collaboration between DZCA and Colorado Animal Specialty & Emergency’s (CASE) passionate veterinarians. Her journey is a testament to the incredible dedication of these staff members and their unwavering commitment to animal wellbeing. 

Keni’s Cancer Journey

In February 2025, animal care staff at Pinnacol African Penguin Point observed a mass on the upper portion of Keni’s beak. She was quickly scheduled for diagnostic imaging at our Helen and Arthur E. Johnson Animal Hospital, where a CT scan and biopsy confirmed a diagnosis of malignant melanoma in her nasal passage.

To determine the best path forward, our Veterinary Medicine team consulted with experts from other Association of Zoos and Aquariums-accredited institutions and veterinary specialists. Based on those conversations, our team decided to move forward with radiation therapy with the generous support of CASE.

Advanced Care Through Collaboration

Keni’s treatment plan includes radiation therapy and immunotherapy using a canine melanoma vaccine—an innovative approach tailored to her unique physiology and condition. On March 26, she was transported to CASE’s Boulder facility for her first round of radiation and the initial dose of her vaccine. She recovered quickly and was eating and behaving normally the very next day.

She returned to CASE for additional treatments on April 3, 9, and 17, ultimately completing a total of four radiation therapy sessions and receiving two doses of immunotherapy. Throughout it all, Keni has shown remarkable resilience and continues to do well under the careful observation of her animal care and veterinary teams.

“At CASE, we are honored to collaborate with the dedicated team at Denver Zoo Conservation Alliance to provide advanced radiation therapy and immunotherapy for Keni,” said Dr. Clarissa Freemyer, a Radiation Oncologist at CASE. “Our goal is to tailor treatment to her unique needs while prioritizing her comfort and quality of life. This partnership exemplifies the power of veterinary specialists working together to provide the best possible care for every patient, no matter how small or unique.”

A Promising Prognosis

Though Keni is still undergoing treatment, her prognosis is positive. The teams at DZCA and CASE are closely monitoring her progress and adapting her care to ensure she stays comfortable and continues to thrive. 

DZCA Clinical Veterinary Dr. Dan Culter shared more about this animal care story:  

“Keni’s treatment has been possible through teamwork and collaboration to make the best decision for her wellbeing. Our animal care staff first noticed the mass and have been instrumental in monitoring her well being so that we have Keni’s quality of life at the forefront. The veterinary teams, both at DZCA and at CASE, have created a treatment plan that addresses the unique challenges of penguin medicine while giving the best chance for overcoming this disease.” 

Guests can visit Keni and the rest of our flock at Pinnacol African Penguin Point, sponsored by Pinnacol Assurance, where our commitment to conservation and care is on full display. This new habitat is designed to support the physical and emotional wellbeing of this Critically Endangered species, while also educating guests about their urgent need for conservation. 

Saving Wildlife Together

Keni’s journey highlights the extraordinary level of veterinary expertise and compassion that defines the work of DZCA and CASE.  

Her treatment is just one of the many ways we are Saving Wildlife Together—not just through field conservation, but through everyday care for the animals who call DZCA home.

Celebrate World Arbor Day with DCZA

Written By: Viktoria Barr, Arbor Specialist

Why Trees Matter

We all know that trees are important, but do you know why trees are important? Aside from providing the oxygen we breathe, trees come with copious amounts of benefits to us as humans, to native wildlife, and to all of the animals that call Denver Zoo Conservation Alliance home. To name a few of these benefits, trees provide shade, food, shelter, and even monetary and medicinal benefits. Without trees, we would not have the everyday items we love like coffee, aspirin, paper, rubber, lumber, and of course, fruit! Trees also regulate our climate, cool our cities, conserve water runoff and erosion, and sequester carbon from the atmosphere. It’s also been shown that trees can relieve stress and provide positive changes in mental health to humans and animals, just by existing in the same space as them.  

And so, every year on the last Friday of April (this year, April 25), we celebrate Arbor Day—a day where we can raise awareness about the vitality of trees and encourage sustainable tree planting and care globally and throughout our communities.

The Importance of Long-Term Tree Care

Like yourself, trees in the urban environment need to be cared for after being planted just as you need cared for after you are born. Trees require maintenance throughout their life, like staying hydrated, getting routine haircuts, and making sure they are getting all of their vitamins as they grow up. Imagine how your hair might look if you went five or 10 or 20 years without a haircut—it would probably become quite unruly! It’s very similar for trees. Routine trimming of live branches and the removal of dead limbs is necessary for overall tree health and will reduce the chance of someone becoming injured by falling branches.

The Coexistence Between Healthy Trees, Wildlife and Ecosystems  

To properly care for a tree from cradle to grave, there are a few things you must consider. 

First, where is the tree going to be planted? Have you selected a tree that is “native” or local to the region in which it will be planted? Picking out trees that are local to the region in which you wish to plant them will benefit you, the trees, and the local wildlife. In Denver, a tree might be able to survive our hot, steppe climate with ample watering, but it would likely be better to select a tree that does not require a lot of watering – which will save you time, money and is much more sustainable in the long term (since Denver does not receive a lot of rainfall).  

Additionally, local wildlife has evolved to coexist with localized plant species and typically form mutualistic bonds (meaning both parties benefit). Planting noxious and non-native trees should be avoided, as they can become uncontrollable and take over habitat for native species, potentially becoming invasive if they are not already deemed so (the Tree of Heaven or Ailanthus is a prime example of this).  

Additionally, planting “native” or “local” isn’t good just because it’s a popular buzz term. When you plant native and/or localized trees (and shrubs and flowers), local wildlife (pollinators, furry critters, insects, etc.) all benefit because they have formed symbiotic relationships with each other. For example, the Colorado Hairstreak (Hypaurotis crysalus, Colorado’s state insect) is a beautiful purple butterfly that relies solely on the gambel oak tree (Quercus gambelii), which grows here naturally. 

You may have noticed that some oaks tend to hold onto their leaves all throughout winter and then drop them when new leaves emerge in the spring—the gambel oak is no exception to this. An adult Hairstreak lays its eggs on a gambel oak leaf in the fall/winter, and then when the caterpillars hatch in the spring, the caterpillars eat the new, young oak leaves. After the caterpillars pupate into adults, they eat sap from the tree. If the oaks were to drop their leaves in the fall/winter, this relationship would not work. 

Colorado Hairstreaks will never leave the grove of gambel oak trees where they were hatched, and under ideal conditions, gambel oaks can survive well past 100 years old. This is just one example of how trees benefit our wildlife, but it’s easy to see how important they can be to even one (albeit small) species! 

A Simple Way to Celebrate Arbor Day 

This Arbor Day, consider taking a walk around the Zoo or your neighborhood and take in all of the benefits that trees provide for us. How many different species of trees can you name while you walk? Do you notice any birds or animals using the trees? Do you come across anything that might not exist without trees (park benches, light poles, books, etc.)? Consider where you might like to see more trees planted—and who might ultimately benefit from them for many decades or centuries to come.

Sustainability in Action: DZCA’s Commitment to a Greener Future

Written By: Stephanie Bramwell, Sustainability Coordinator

Environmental sustainability, responsible use of resources now to ensure adequate resources for the future, is a priority for us at Denver Zoo Conservation Alliance (DZCA). We recognize that to save wildlife, we need to preserve wild spaces. The Environmental Department at DZCA leads staff, volunteers, and guests in sustainability efforts year-round. We’re working to reduce waste production, water usage, and energy consumption to the greatest extent possible, while providing exceptional care for our animals and awe-inspiring moments for guests.

Read on to learn more about how DZCA reduces waste, water, and energy.

Waste

Have you ever considered why waste signage is so confusing? This may not be a question most people ask, but DZCA’s staff think about trash a lot. Something as simple as a sign on a trash can sounds mundane; however, there’s a lot of variety in how waste is communicated. Is it “trash” or “landfill?” Are recycling bins blue or purple? These variations can cause confusion at the bin. 

To help address this confusion, DZCA set out to create a standard and common language across the Front Range. In 2024, our staff collaborated with several public-facingcommunity-based venues—including Denver Art Museum, Denver Arts & Venues, Denver Botanic Gardens, Denver International Airport, Denver Museum of Nature and Science, and Greener Theatre Colorado—to co-create a guide that sets boundaries on the symbol, terminology, and color used for waste bins.  

The goal in doing this work is for each organization to speak the same language with our waste signage. This way, when you visit the Zoo, rock out at a concert, cheer on our local sports teams, or catch a flight for vacation, we’ve reduced some of the confusion. We know we have a long way to go to improve waste diversion across the Front Range, but this is one move in the right direction. 

Blair Neelands, Director of Sustainability & Environmental Compliance, and Cassie Williams, Signage Project Manager, presented the project to colleagues at the mid-year conference for the Association of Zoos & Aquariums this March. Some institutions were interested in using our guide and others were inspired to work with their community to create their own standards.  

DZCA will be using the standards to update the waste signs later this year. You may not have noticed our waste signs before, but you might now! 

Water

Did you know the water in Denver flows to the South Platte River and eventually to the Mississippi? Millions of people, as well as wildlife and their habitats, are touched by this water. We’re doing our part to keep the South Platte clean by installing gutter bins in storm drains around the Zoo.  

Gutter bins are mesh bags that sit just below the grate of storm drains and catch any litter, rocks, mulch, or other debris that may enter the storm drain, while allowing water to pass through. When the bags fill up with debris, Zoo staff empty the gutter bins in the trash and then return them to the storm drains. There are currently ten gutter bins at DZCA and we’re planning to purchase more over the next few years!  

Energy

Tropical Discovery is historically the highest energy user at DZCA, accounting for 20% of the Zoo’s energy consumption. This is unsurprising because it is home to approximately two-thirds of animals at the Zoo and is a tropical rainforest in the middle of Colorado. Over the past two years, we’ve invested in large and small projects aimed at reducing the energy consumption of the building.  

In 2023, we purchased a new cooling tower and upgraded Life Support Systems (LSS) pumps, staged boilers to reduce energy demand, cleaned HVAC coils to reduce stress on fans, and switched to bag filters to improve system efficiency. These upgrades resulted in a 53% reduction in electricity and 10% reduction in natural gas in 2024, compared to the previous 5-year average.  

Building on this success, in 2024 we closed Tropical Discovery to guests for two months in order to replace 13,000 sq. ft. of skylights. The new glass is expected to better insulate the building; keeping more heat in the building will reduce energy consumption and heating cost. We’re eagerly waiting until the fall of 2025 to compare a full year of post-roof improvement data with the building’s previous energy consumption.  

Frog in Tropical Discovery at Denver Zoo

Life at the Zoo has a variety of complex needs, from our animals to guests and staff. Investments in energy, water, and waste reductions are investments in the future well-being of the animals and people in our care, often with current benefits like clearer signage, reduced flooding, and lower energy bills.

You can support our sustainability efforts during your next visit to the Zoo by bringing a refillable water bottle, separating recycling from trash, and keeping an eye out for information about how your environmental sustainability efforts help save wildlife.

Specialized Care for All Creatures

At Denver Zoo Conservation Alliance (DZCA), we believe that every animal—no matter its size, species or age—deserves the highest standard of care. Our Animal Care and Veterinary Medicine teams’ recent work with Vader, a 10-year-old emperor scorpion, is a testament to this philosophy. Thanks to collaborative care, innovative treatment methods, and the dedication of our expert teams, Vader has made a full recovery. She continues to thrive at DZCA, well beyond the typical lifespan of her species.  

Meet Vader: Small Ambassador, Big Impact 

Vader, an emperor scorpion who has called DZCA home for 10 years, is a beloved member of our Animal Ambassador program. For over a decade, she has inspired guests of all ages, showcasing the important role scorpions play in healthy ecosystems and helping dispel common misconceptions about these fascinating arachnids. One of the coolest facts about Vader, like all scorpions, is that she glows under ultraviolet (UV) light thanks to a special compound in her exoskeleton. Scientists are still exploring why scorpions fluoresce, but theories include camouflage, communication, and sun protection.

In human care, emperor scorpions typically live between five and eight years. But thanks to the specialized care she receives at DZCA, Vader is thriving well beyond that average life expectancy at 10 years old. 

Collaborative Care

A few months ago, Vader’s Animal Care team noticed her abdomen was swollen. As a geriatric scorpion, Vader needed special attention to determine the root cause of her condition. Our Veterinary team anesthetized Vader in our state-of-the-art Helen and Arthur E. Johnson Animal Hospital for a full physical exam and hemolymph (blood) collection. 

Through blood chemistry and culture testing and collaborating with our colleagues at the Butterfly Pavilion, we confirmed that Vader had a bacterial infection in her bloodstream. This condition is known as septicemia which can be life-threatening for invertebrates like scorpions. 

Transformative Treatment

After being diagnosed, Vader received topical antibiotics daily for two weeks, a custom enema, and detailed husbandry adjustments by her animal care specialists. To reduce handling stress, our team even designed innovative, low-stress restraints to administer her treatments safely and effectively.

Clinical Veterinarian, Dr. Spencer Kehoe, DVM, DZCAM, reflected on this innovative care:  

Vader’s story is a great reminder of the compassion and innovation that drives everything we do at DZCA. We’re proud to invest in the highest quality care for all animals, regardless of their size or species. Whether it’s an emperor scorpion or a French angelfish receiving a CT scan, our dedicated Animal Care and Veterinary Medicine teams work together to ensure every animal receives expert, compassionate care tailored to their unique needs.

Carbon-Free Conservation

Written By: Jessica Meehan, Logistics Coordinator 

There is one thing that unites Denver Zoo Conservation Alliance (DZCA) staff and volunteers, and that is a passion for wildlife conservation. Our mission to Inspire Communities to Save Wildlife for Future Generations drives us to connect with those working to save species where they live, from breeding and releasing boreal toads in our local Rocky Mountain region to partnering with the grassroots NGO Forum Konservasi Leuser in Indonesia.  Since 2018, DZCA has partnered with Kea Conservation Trust (KCT) by providing grant funding to support several important projects aimed at improving conservation outcomes for this endangered parrot species only found on the South Island of New Zealand.

One thing about being passionate about a species that lives across the world is that it is costly in terms of time, money, and carbon to participate in field conservation projects to support them. While I was lucky enough to visit New Zealand to help capture and band kea as part of the lead testing program in 2020, it is not practical to send DZCA staff to New Zealand regularly. Fortunately, while in New Zealand the connections I made led to conversations about how I could keep helping with kea conservation from across the world, and the Kea Database Project was born.  

Fast forward several years, our database entries were complete and KCT had a new partnership to explore. The curious kea are notorious for causing damage to property as they investigate the buildings in their range, and KCT gets regular complaints about destructive behavior from property owners. Besides the damage, kea can be injured or ingest toxic materials like lead from old roofing nails, causing illness or even leading to death.  

KCT has tried using motion-detection strobe light machines to deter kea from properties, but it was unclear if these were making any difference in kea behavior. For this naturally curious species, something novel like a strobe light might even attract kea! Field researchers had the idea to set up cameras to monitor the activities of kea at these properties. DZCA supplied a small grant to cover the cost of several new motion activated strobe lights equipped with an alarm sound, and cameras were deployed at several sites with and without a strobe light present to provide a control group. But researchers found that the cameras came back with thousands of files that needed to be reviewed in order to find any useful information. Many of the photos and videos were taken when the cameras were activated by the wind, people on the property, or other non-kea activities.

DZCA staff were happy to jump in again to take care of the tedious desk work so that field staff in New Zealand could spend their valuable time out in the field with kea. I recruited a new team of conservation-oriented Animal Care Specialists to create a coding system for analyzing the videos and photos, and we dove into the storage drive. Over the course of 25 work hours added up over 6 months our team coded over 27,500 pieces of media. Our spreadsheet allows field researchers to quickly find and view the videos and photos that are worth viewing to compile preliminary information to share with property owners, and we hope that when we add more data points there will be enough evidence to determine whether strobe lights are effective tools for deterring kea from damaging property.  Since it’s been the winter and slow season down under in New Zealand, we’re currently waiting on more media to be available for analysis so we can jump in again once the cheeky groups of juvenile kea begin their antics in the villages of the Southern Alps.   

Our partnership with the Kea Conservation Trust demonstrates that impactful conservation can happen from anywhere. While fieldwork in New Zealand is crucial, our behind-the-scenes efforts from Colorado are making a real difference for kea. We look forward to continuing this collaboration and supporting the conservation of this endangered species!

Supporting Global Conservation Without Leaving Home

Written By: Angela Yang and Katie Glatfelter

At Denver Zoo Conservation Alliance (DZCA), conservation is at the core of everything we do. While some of our dedicated teams work directly in the field, we recognize that meaningful conservation extends far beyond those efforts. Whether in the field, at the Zoo, or in everyday actions, there are countless ways to support wildlife and habitat conservation. Angela Yang, Senior Advisor for Global Conservation, and Katie Glatfelter, Animal Care Specialist for Primates, share how making a global impact doesn’t always require traveling—sometimes, it can start from home with a simple question: “What do you need?”

The Shift in Conservation 

Thirteen years ago, Rainforest Alliance produced an entertaining video called “Follow the Frog” that follows an average person who, driven by his passion to do more for the environment, takes all the wrong actions including leading a failed revolution in Nicaragua.  Eventually, the campaign leads the viewer back to more tangible and rational measures based on consumer behavior.  Trust us, this video is three minutes well-spent. 

More than ever, this message resonates today as conservationists strive to decolonize our approaches and recognize, as well as prioritize, Indigenous knowledge and locally led conservation and community-based efforts. It is no longer acceptable, nor necessary, for those of us from the Global North to “parachute in” to save wildlife but rather support the work of local actors and organizations working with their own communities.   Instead of capacity-building, we now use terms such as capacity-strengthening or better yet, capacity-sharing.  Because knowledge-sharing goes both ways.  

DZCA’s Conservation Strategy 

In that vein, when the Field Conservation department revised our strategy in 2022, we focused building alliances with strong local organizations that are protecting species based on DZCA’s criteria. As of 2025, we have eight exciting partnerships around the world featuring species from grey crowned cranes to Asian elephants.  And as we grow our trusted relationships, we are intentionally seeking opportunities for DZCA staff to engage at the intersection of partner needs and our expertise and interest.  

One Question, Big Impact

One of these opportunities happened with our partner in Laos, Association Anoulak. Through our former small grants program, Katie Glatfelter, one of DZCA’s Primate Animal Care Specialists, reached out and we discussed our partners. Katie has a strong background in animal care and has also worked with wildlife in South Africa, Namibia, Mongolia and the Galapagos Islands. While studying for her Masters degree, one of Katie’s professors shared that what conservation organizations and projects need the most help with are not what one would expect.   

Often when people want to get involved with field conservation, their first thought is to travel to the location of the project and help directly in the field. Katie learned throughout her experiences that this is not always what is needed, and that often the best way to get involved is to simply ask “what do you need?”   

She took this approach with Dr. Camille Coudrat of Association Anoulak and discovered that Camille didn’t need her to go to Laos. She needed Katie to create some education tools for an upcoming training for emerging Lao conservationists to learn more about conserving their local, threatened wildlife. So, Katie, with illustrative support from former Animal Care Specialist Brittany Merlo, created a beautiful a series of species factsheets in English that were also translated into Laos and used in a successful two-week pilot training course, that we’ll be supporting again in 2025.  

A Conservation Win-Win

This wonderful “alliance” showed that getting involved with international field conservation is easy and you can make a difference without leaving home. In this win-win story, Katie proudly contributed to an important cause in a simple way that will make a difference for both people and wildlife. As we continue expanding our partnerships, we’re excited to create more opportunities for staff—and passionate conservationists everywhere—to make a real impact.
