Each year Nature Walk volunteers engage with an estimated 250,000 visitors, most of them younger children, role modeling the idea that caring about conservation is cool

Wally Hlavac, a conservation biology major at the University of Minnesota, spent his summer traipsing across Madagascar, doing field surveys of the island’s birds, butterflies, and lemurs. He credits his time as a Como Nature Walk volunteer with helping him take the first step. 

Hlavac was a summer camper at Como several years ago when he encountered his first Nature Walk volunteer, one of 50-some teens recruited each spring and summer to help bring Como’s animal and plant collections a little closer to Como’s nearly two million annual visitors. “I think he came in to show us a rabbit, and I decided that was something I really wanted to do, too,” says Hlavac, who applied and was accepted into the selective program when he was in ninth grade. 

Through Nature Walk, teens are provided training on a variety of Como’s conservation themes, from the rainforest and reptiles, to beneficial bugs and plants, that they go on to share with Como visitors at interpretive stations arrayed around Como’s grounds. “It was the first time in my life that I got to teach people about conservation and concepts that I’m really passionate about,” Hlavac says.

The program, which includes professional development training, also pushed him to develop greater confidence and public speaking skills. “I was a really awkward kid, but being able to go to Como and talk to people, and answer their questions was really great for me,” he says. “It motivated me to try hard, and get Como visitors engaged, because those encounters felt really good.” Each year, in fact, Nature Walk volunteers engage with an estimated 250,000 visitors, most of them younger children, role modeling the idea that caring about conservation is cool.

After a pause during the pandemic, Como’s Nature Walk program was back at full power this summer, with a full complement of teen volunteers on campus sharing their insights on the smallest insects and the tallest giraffes. While not every teen will go on to pursue careers in conservation, Hlavac says there’s no doubt the experience helped him recognize that protecting the natural world could be his calling. 

“I think the overall curriculum of Nature Walk really does inspire a love for natural science in any capacity, and learning more about animals and plants and being able to share that with people was really exciting,” he says. “I know it really cemented conservation in my mind as something I want to continue doing.”

This year, your support for Como Friends made it possible to invest in Como’s Nature Walk program with the hiring of Maddie Becker to fill a new assistant role.“Working with Nature Walk has been a fantastic experience. The kids have worked hard this summer, and it’s been so uplifting to help foster an environment where they’ve not only been so welcoming and enthusiastic with the guests that visit their carts, but also in their relationships with each other. Each day they express so much joy for life and the natural world that I am left with nothing but immense hope for our future.”

As a Conservation Champion, Como Zoo primate keeper Em Brunmeier traveled to Peru to learn more about spider monkeys in the wild

Behind the scenes in Como Zoo’s Primate Building, Brunmeier has become a big fan of the four spider monkeys in her care—Gomez, Katie, Ellie, and Jazz—and she applied to learn more about their cousins in the wild through Conservation Champions, the Como Friends micro-grant program that encourages Como’s keepers and horticulturists to take part in conservation efforts in the field. After researching conservation projects around South America, she decided that the Kawsay Biological Station in Puerto Maldonado, Madre de Dios, Peru was the place to be. 

“What was really special about this location was that the team there had been able to bring back and restore a spider monkey population that had been locally extinct, and that was something that I was really excited to be part of, and to see how they were managing that,” she says. “They also work with other scientists in the area, like botanists and PhD students from abroad to research other parts of the ecosystem and how they all correlate with spider monkeys. I really wanted the chance to learn more about how all of these factors come together.” 

As part of the project, Brunmeier joined a team of researchers tracking spider monkeys that had been previously released into the Tambopata National Reserve to study the seasonal variation of their behavior. “With no GPS collars or other tracking devices, it was quite a task,” she says. “We had no guarantee we would find them and had to go pretty far into the Amazon rainforest.” But once the spider monkeys were located, Brunmeier got the chance to hear the full chorus of their vocalizations. “For spider monkeys in the wild, their home range is nearly 700 acres, and they often split up their group and then reunite at night to sleep together,” she says. “To do all of that requires quite a lot of logistics, so they’ve come up with quite a lot of vocalizations. They have little chirping sounds that they make when they’re close to each other, and really loud, bellowing calls that they use to try and find each other over long distances. It was so fun listening to them—they  have lots of things to say.” 

During her two and a half weeks in the field, Brunmeier also got the chance to care for young spider monkeys in a rehabilitation facility. “That’s where my personal expertise came in handy, because hands-on care of the animals is what I do every day,” she says. “I was also able to talk with the team about how we do primate enrichment at AZA [Association of Zoos and Aquariums] institutions in the U.S., which is something I’m passionate about.” 

Caring for polar bears every day can be exhausting. Just ask Como Zoo’s Julie Yarrington, one of a team of aquatics keepers who keep an eagle eye on Como’s three polar bears, Nan, Kulu, and Neil.

Earlier this year, Neil was diagnosed with gastric dilatation-volvulus, or bloat, an urgent medical condition that required emergency surgery. Surgery is a risk for any animal, but especially for one as old as Neil, now nearing 28 years of age, and one of the oldest male polar bears in North America.

“Because of his age, there was a high risk that he wouldn’t rebound,” says Yarrington, who spent more than a month “just hoping we could get him to eat, eat, eat. It was very mentally exhausting.”

Fortunately, after a few weeks, Neil pulled through and has been very particular about his diet, showing a strong preference for his favorite comfort food of canned salmon and canned tuna. As Neil has regained strength and been reintroduced to his companions, keepers have changed the polar bears’ feeding schedule to cut Neil’s risk of further complications. “Instead of getting a big breakfast in the morning, we now feed him three to four times a day,” Yarrington says. 

To allow his incision to heal, Neil had to stay out of the water and away from his favorite companion, Nan, a feisty 28-year-old female. Brought to Como Zoo three years ago in order to be a non-breeding partner to Neil following the death of Buzz, his twin brother, the pairing between the two elder bears has worked out beautifully. 

“Neil just wants to be wherever Nan is,” says Yarrington. “It was hard for him at first, but once it healed up he was able to get to the pool and was able to clean himself up. Guests may not really notice his incision site, which is already covered up by fur.”

Your Give to the Max Day contributions to Como Friends help to provide cutting-edge veterinary care to animals like Neil, ensuring both great veterinary care and the creature comforts that keep animals healthy and curious. “While he’s been recovering, he’s also been into his other favorite foods, Cool Whip and sherbet—in moderation,” Yarrington says. “When you live to be the oldest male polar bear in North America, you definitely deserve a couple of spoonfuls of sherbet.”

A trip to the Polar Bear Capital of the World helped teach Como Zoo keeper Kristin Riske new ways to talk about climate change

Back in 2008 when the polar bear became the first animal listed under the Endangered Species Act to be threatened primarily by climate change, we all learned how individual choices here at home can help improve conditions in the Arctic. From turning off unneeded lights, to driving less, to choosing products with less packaging, many zoo visitors at Arctic Ambassador Centers like Como Zoo are now well-versed in all the individual choices that can contribute to a more sustainable future. 

But could there be a better way to talk about what’s happening to polar bears?

That’s the question Como Zoo aquatics keeper Kristin Riske has been exploring as a Conservation Champion, the Como Friends program that funds professional development experiences and on-site field work for several zookeepers and horticulturists each year. With support from the program, Riske joined a cohort of other keepers and educators in the Climate Alliance Program, a unique Polar Bears International partnership program aimed at empowering conservation professionals—many, like Riske, who care for polar bears every day—to effectively communicate about climate change and inspire real-world solutions.

“Como has been part of the Arctic Ambassador Network for years, and this program is designed especially for institutions like ours,” Riske says. “As zookeepers, we’re in a great position to get the message out to the public.”

The program started early in 2023, as Riske and other zookeepers and educators took part in an eight-month online learning course, created in partnership with National Network for Ocean and Climate Change Interpretation. Through the training, Riske learned about the latest best practice communication strategies around climate change, and how building awareness and support for climate solutions has evolved over time. 

“Having this training through Climate Alliance really changed my view on how to get the message across,” says Riske, who got her start as a Como Zoo intern back in 2014. “Back when I started, it was all about how we should turn off our lights and recycle, but through this program, I’ve learned it’s more about the collective action that we need to take—voting for the climate, creating community gardens, shifting to renewable energy, advocating for community-wide or city-based sustainability programs.” 

Last month, the Climate Alliance Program culminated in a week-long trip to Churchill, Manitoba, the polar bear capital of the world. “It was really early in the season, still in the 40s and 50s, so we only saw one bear—a female sleeping near the coast,” Riske says. “But being out in the Tundra Buggy exceeded my expectations in every way. We got to see ptarmigan and caribou, and got the chance to meet and talk with the indigenous people of Churchill who told us more about the land around us.” 

Now back at Como Zoo where she cares for polar bears Neil, Nan, and Kulu, Riske says her Conservation Champions experience continues to inspire her. “There really are no words to encapsulate what I experienced,” she says. “I went into this Climate Alliance program to learn more about polar bears, climate change, and what we can do to help. What I didn’t know was the bond I would form with all of these amazing people from different facilities that want to do the same thing. I am still processing my experience up in Churchill, but one thing I do know is I have become more empowered, and a spark has grown in me that wants to advocate for climate change. I can’t thank Polar Bears International, Frontiers North Adventures, Como Park Zoo and Conservatory, and Como Friends enough for this once-in-a-lifetime experience.”

With chrysanthemums playing the starring role in this season’s Fall Flower Show, it’s a guarantee that thrips will also be part of the cast. 

Also known to gardeners as thysanoptera or thunderflies, these needle-thin sucking insects love to feed on mums, causing damage to plants, or worse, transmitting viruses from one plant to the next.

Fortunately, Como’s horticulturists have a tiny but mighty weapon to keep thrips from ruining the show. Known as the cucumeris mite, this half-millimeter predator insect has just been deployed throughout the mum crop destined for the second half of the Fall Flower Show. With an appearance like that of a transparent wood tick, and the ability to prey on thrips and survive on plant pollen, these super small super predators play an important role in the Marjorie McNeely Conservatory’s Integrated Pest Management plan. 

“People sometimes think that spraying pesticides is the only way to control pests, but integrated pest management is an approach that combines anything you might do to make a plant healthier, from the condition of the soil it’s growing in, to your nutritional program, to how you’re pruning the plant,” explains Como horticultural supervisor Bryn Fleming. While Como has been a low-pesticide growing facility for decades, Fleming says, “our reliance on beneficial insects has increased more recently,” as the gardening industry embraces more sustainable ways to manage greenhouses and gardens.

While beneficial bugs show great promise in cutting the use of pesticides, monitoring how well predator insects perform can be time consuming and complex. What’s the right dosage of beneficial insects for a particular plant or crop? How do shifts in such inputs as light, water or temperature affect the efficacy of beneficial bugs? Are some pest predators better than others?

To help answer those questions, the Marjorie McNeely Conservatory is now equipped with a new integrated pest management scouting system called IPM Scoutek. Made possible by your support for Como Friends, this new digital technology tracked on a tablet allows horticulturists to collect data from greenhouses and gardens to make even more informed decisions about how to care for crops and manage pests. 

“This technology is used by large-scale growers who are producing bigger agricultural crops, but is also used for nursery or floriculture production.” says Horticulturist Jen Love, who recently shared news about Como’s software scouting system during an American Public Gardens Association symposium at the Franklin Park Conservatory and Botanical Gardens in Columbus, Ohio. “As far as we know, as a public garden the Marjorie McNeely Conservatory is an early adopter trying this approach, and there’s a lot of interest from other institutions in seeing how this process works. If it’s successful, it’s a model we can share with other botanical gardens.”

As Como’s horticulturists discover what digital technology can do for pest management, Fleming says the Conservatory’s early adopters are already impressed by what they’ve seen. “I think this software is going to help us to keep track of things at a much closer level, so when problems come up we can respond to them even sooner,” she says. “To care for a living collection requires constant adaptation, and this technology will help us be a little more proactive than reactive.”

Conservation Champion Jill Erzar traveled to Tanzania to help Wild Nature Institute track giraffe across the Serengeti

“Giraffes have been very underestimated, and under-researched for a long time,” says Como Zoo keeper Jill Erzar. “But over the last decade or so, that’s begun to change, and we’re beginning to understand that giraffes are, in fact, highly intelligent, with social hierarchies and relationships that are as complex as elephants and chimpanzees.”

Reaching heights of 18 feet and beyond, giraffes are the tallest mammal on earth. 

But with brains that are relatively small compared to their body size, scientists haven’t always been sure if their elevators go all the way to the top. 

“Giraffes have been very underestimated, and under-researched for a long time,” says Como Zoo keeper Jill Erzar. “But over the last decade or so, that’s begun to change, and we’re beginning to understand that giraffes are, in fact, highly intelligent, with social hierarchies and relationships that are as complex as elephants and chimpanzees.” 

Thanks to a recent grant from Como Friends’ Conservation Champions program, Erzar herself has been contributing to that body of research as a volunteer for the Wild Nature Institute. The conservation group behind the largest demographic survey of giraffes in the world, Wild Nature Institute takes a non-invasive approach to giraffe research, relying entirely on photographic identification to track the births, deaths, movement and social bonds of about 4,100 individual giraffes across 25,000 square miles of the Tarangire and Serengeti ecosystems in Tanzania.  

As a seasoned giraffe keeper who can spot the subtle difference in every giraffe’s unique markings, Erzar’s well-trained eye and expertise were a welcome skill set on the Serengeti this summer, as the conservation group worked to compare and analyze more than a decade’s worth of data about wild giraffe. “I was able to make more than 9,000 matches during the 10 days I spent in country,” says Erzar, who also got the chance to meet and learn from giraffe experts in the field.  “For me the biggest take-away from this trip is that giraffes need protected areas because poaching is still their number one risk. Even with projected climate change impacts in that area, nothing threatens their survival as much as illegal hunting and poaching.” 

Though it will take time for Wild Nature Institute’s findings to be published and shared more widely with other conservation researchers, new discoveries about giraffes are coming to light all the time. For instance, scientists who once considered giraffes to be aloof and anti-social have discovered that in fact, giraffes live in complex social systems and super communities, and even prefer to eat with favored companions. A 2023 study found that giraffes are capable of statistical reasoning, while a 2021 study found that giraffes prefer a fair fight, and will only spar with individuals of the same size. Another growing topic of interest within the giraffe field is the so-called “grandmother hypothesis,” a theory that suggests that menopausal female giraffes may have an important role to play in raising young. 

“It’s really cool to see that giraffes are finally having their moment, and I absolutely love being on the forefront of a group that believes that non-invasive [data gathering] is the best way to study them,” Erzar says. 

Como Friends’ Conservation Champions program, funded with donations from our generous supporters, has made it possible for Jill to travel to Africa three times in recent years, supporting conservation partners in the field, while bringing home new experiences and insights that can help enhance the care she gives to animals at Como Zoo every day. “Making the trip to work with Wild Nature Institute helps me to tell the story of our own giraffes better,” she says. “I can tell visitors that our giraffes really do look and behave just like the giraffes in Tanzania. And the more we learn about giraffes, the more we can do to improve their welfare in the wild and here at Como.”

The biodiversity of Como’s rainforest habitat requires complex care  

“When we try to pick out anything by itself,” the famous naturalist John Muir once wrote, “we find it hitched to everything else in the Universe.”

The profound interdependence of plants, animals and people is one of the lessons Como Park Zoo & Conservatory strives to convey to more than a million visitors every year, and nowhere is that lesson more evident than in Tropical Encounters. Opened in 2006, the immersive rainforest habitat features an extensive array of tropical plants and trees, and an equally diverse range of animals, from high-flying tanagers, to a slithering anaconda, to Chloe, Como’s beloved free-ranging sloth.

With so many living things under one roof, Como Zoo keepers and Marjorie McNeely Conservatory horticulturists collaborate closely within Tropical Encounters to ensure that making a change in one corner of the habitat doesn’t have negative impacts for other residents of the rainforest. That’s why the Tropical Encounters team is taking its time on a major soil replacement project this season paid for by your contributions to Como Friends.

Visitors this summer may notice that horticulturists are taking a staged approach to the process, removing spent soil from one location at a time, to make sure that the root systems of rainforest trees and the animals that live in the vicinity are all thriving. The effort is a little bit like repotting a giant terrarium, says horticulturist Diane Rafats: “We do take special care in this habitat. Everything we do here can affect everything that lives here.”

Private support secured by Como Friends is critical to making behind-the-scenes improvements that keep every corner of the Marjorie McNeely Conservatory healthy and thriving. This year, Como Friends’ funding will also support a new lighting system for the North Garden’s gorgeous collection of economic plants, a new sound system to improve the experience for visitors, and a new design plan to renovate and repair Como’s popular Victorian Water Garden pool. Thank you!

It’s been a busy season of new arrivals at Como Zoo

Stanley, Houdini, Mutambi, Stevie….there are a lot of new names to match to new faces at Como Zoo. Here’s a sneak peek of the new animals you should be sure to meet on your next visit.

Your support helps connect Como Zoo’s gorillas to their cousins in central Africa

When Como visitors see bachelor gorillas Virgil, Jabir and Samson napping the day away in their indoor habitat at Gorilla Forest, they sometimes ask primate keeper Michelle Hays if their wild cousins in central Africa would be doing the same thing.

“The answer is definitely yes,” says Hays, who served as a volunteer with the Projet Gorille Fernan-Vaz, a grassroots gorilla preservation initiative in Gabon back in 2019. “One of the big take-aways of my time working with gorillas in their natural habitat is that they really do spend their days eating, resting and sleeping,” she says. “It was cool to see that our gorillas are doing just what these wild gorillas would be doing. It might look a little different here at Como Zoo than it does in central Africa, but they’re basically behaving in the same way.”

Enhancing Como Zoo keepers’ first-hand experience and personal insights about animal behavior was one of the goals of Conservation Champions, a program funded by donors to Como Friends that has helped send Como keepers, educators and horticulturalists to assist with real-life conservation efforts around the world since 2017. From tracking snow leopards in Kyrgyzstan, to rehabilitating injured and orphaned penguins in South Africa, to saving sloths in Costa Rica, the Conservation Champions Program has also helped Como staff to build a network of new professional connections within the world of wildlife conservation. 

While pandemic precautions put a pause on international travel plans for the past two years, the Conservation Champions program has continued to provide support for conservation fieldwork, with a variety of small grants to support partners that Como staff have built connections with. One such grantee is Projet Gorille Fernan-Vaz, which recently received a $2,000 grant from Como Friends for help with the construction of an enclosure that will allow two orphaned female gorillas rescued from poachers in October 2020 to be integrated with the 9 gorillas already living on Rehabilitation Island. The organization has been posting frequent progress reports about the effort on their Facebook page this winter. Their goal is to introduce the pair—Niout and Maya—to a stable group of nine gorillas that now live at Projet Gorille Fernan-Vaz’s Rehabilitation Island. 

“I love being able to talk about my time on the ground in Africa working with such a dedicated team of gorilla supporters, and connecting it full circle back to the conservation messages we give to visitors here at Como,” says Hays. “I’m proud to say we’re supporting such an incredible project, and hopefully helping them achieve their ultimate goal of possibly releasing this group of soon-to-be eleven gorillas back into their wild habitat.”
