It was with profound sadness that the Yukon Wildlife Preserve (YWP) shared the death of Jesse, a cherished and iconic moose who had resided at the Preserve since 2016. The YWP’s Animal Care team made the difficult decision to euthanize Jesse on June 19, 2025 due to complications following a medical procedure.

An Old Injury

The YWP Animal Care team had been monitoring Jesse’s old hoof injury, which had become arthritic, causing her increasing discomfort and pain. The team had diligently monitored her condition, exploring options to alleviate her suffering and improve her quality of life. On Monday, June 17th, Veterinarian Dr. Cassandra Andrew and the YWP Animal Care team immobilized (anesthetized) Jesse to provide a targeted treatment for the affected hoof joint. While under anesthesia Jesse regurgitated contents from one of her stomachs – one of the risks of anesthesia in ruminants like moose. Recognizing the immediate risk, the team promptly cut the hoof treatment short, administered broad-spectrum antibiotics, and reversed the anesthesia.

Complications and Consequences

Upon waking, Jesse exhibited signs of respiratory distress, including coughing and more rapid breathing than normal, indicating that she had inhaled some of the regurgitated material. Later that day, the team provided additional medication to help reduce fever and inflammation. By Tuesday, June 18th, Jesse appeared to be more relaxed and showed initial signs of improvement as the team continued to monitor her closely.

However, during the morning check-in on Wednesday, June 19th, it was clear that Jesse’s condition had declined significantly overnight. She was suffering from what was suspected to be severe aspiration pneumonia (inhalation of foreign/food material into the lungs) and was struggling to breathe. Unfortunately treating such a severe condition can be quite invasive and would only be feasible with a domesticated animal in a clinical setting. The team made the difficult decision to euthanize Jesse without delay.

Dr. Andrew performed a gross necropsy, which confirmed extensive damage to her lungs and the severe pneumonia. The team is conducting additional tests to better understand Jesse’s overall health and to reveal potential future treatments for similar hoof injuries in other animals.

Jesse’s Story

“Jesse was a really special animal with a remarkable story who touched the hearts of many, both our staff and visitors alike,” said Jake Paleczny, Executive Director, Yukon Wildlife Preserve. “Her death is a big loss for our team and so many of our visitors who got to know her so well over her 9 years here. Our team made every possible effort to provide her with the best care, and we will honour her legacy by learning what we can to inform what we do for our moose in the future.”

Jesse’s remarkable journey at the Yukon Wildlife Preserve began in May 2016. At only a few weeks old and weighing just 47 pounds, dogs attacked her in the bush near Whitehorse, separating her from her mother. A quick-thinking teenager (named Jesse) carried the injured moose out and with some help, brought her to the Preserve. The dogs had gone after her neck, causing swelling that made it difficult for her to swallow and breathe. YWP staff provided 24-hour care, and for the first couple of nights, they were unsure if she would survive. For the first four days at the Preserve, Jesse couldn’t get up, and the team fed her via IV, offering small amounts of formula when she could manage it. With her injuries, it’s unlikely Jesse would have survived in the wild. Her comfort around humans meant she would reside at the Preserve permanently.

Jesse’s Impact

If you have a story or memory you’d like to share about Jesse, send it to jake@yukonwildlife.ca  and lindsay@yukonwildlife.ca. We’d like to share and celebrate the impactful experiences and relationships she was a part of.

The crazy snow winter which had packed snow so high people’s heads (and moose heads) were much closer to the top of the fence than normal and Jesse started stealing people’s touques right off their heads. She especially loved to target hat wearers’ taking selfies.

We said our goodbye!
She knows and she listens—
She cried, I cried.

This article was made possible thanks to support from the Yukon 125 Fund. Learn the incredible history of the Yukon Wildlife Preserve, and Yukon Game Farm from the people of the past through this series of articles.

Danny Nowlan is one of Yukon’s colourful, and at times, notorious characters. He was a polarizing figure who cared deeply for animals and connecting them to kids. He was also the subject of one of Yukon’s most expensive trials ever. His work on the Yukon Game Farm would eventually result in the creation of the Yukon Wildlife Preserve. That is a legacy that is still experienced by many Yukoners – although many of the stories are not known or well understood. 

The stories of Danny Nowlan are important threads that are woven through the tapestry of Yukon’s recent history. This project gives us the opportunity to capture and share this history before its lost. This includes the opportunity to celebrate the positive lasting legacy and to learn about and grapple with the challenging aspects of this legacy. 

In 2023 historian Sally Robertson collected oral histories from more than a dozen people who knew Danny. Out of this work, Sally wrote a series of stories about Danny and his adventures.

(9 minute read)

Danny and Erika Nowlan had a dream, and the Yukon Game Farm was established in the mid-1960s. Danny had to struggle several times over the years to keep the Yukon Game Farm operating. It was never profitable until the falcon breeding program was in place. Until 1990, the Nowlans were in business to raise breeding stock and sell young animals to international zoos and wildlife farms. In the case of birds of prey, their market was falconers wherever they happened to live. A Dall’s sheep ram might occasionally bring $2,000 and a trained gyrfalcon might be sold for $13,000, but there were many animals on the Farm, and they all needed care and a constant supply of huge quantities of food.  

Danny considered selling the Yukon Game Farm in the 1970s, when it seemed there would be never-ending bank loans. This was a time when Danny had close friendships with Yukon Game Branch employees, both guardians (Conservation Officers) and biologists. Government biologist Dave Mossop came to Danny with a plan to replenish Yukon’s wild stock of peregrine falcons. This was successful and, building on that, the Yukon Game Farm purchased gyrfalcons from the government and embarked on a successful breeding program.

Danny needed even more money to establish the infrastructure and so, instead of selling the whole property he tried to subdivide and sell some lots along the Hot Springs Road. The government prohibited the sale and Danny’s attitude toward bureaucracy started changing towards antipathy. In the end, the approach of a government official elicited a yell of ‘cops’ from Danny and furious barking from his well-trained dogs. Followed by Danny’s famous laugh.

Prohibited from selling titled property, Danny instead sold 999-year leases. The government challenged this sale, and Danny won in court, so the parcels became titled land. Selling the road frontage kept him in business for a while, and also had the advantage of providing some protection for the animals. Before they were moved away from the road, there were incidents of animals being injured and one ram sheep with trophy-sized horns was killed.

In the mid-1980s, Danny, his second wife Uli, and well-respected biologist Dave Mossop were arrested and dragged into court on charges associated with the capture and illegally selling of endangered falcons to wealthy Saudi Arabians.  Operation Falcon was an undercover operation that started in the United States and reached into the Yukon. The Yukoners were judged not guilty of all charges, but the trial affected reputations and bank accounts. After the trial, the Game Farm’s elaborate infrastructure for breeding, raising, and replenishing wild stocks was in shambles, and Danny and Uli were no longer able to realize a profit from selling the birds they were so successful at raising.

In the 1980s, elk farming became a profitable business in Canada and Danny was quick to acquire a herd of about 300 animals. He and a number of other Yukoners became successful elk farmers before the Korean market for Canadian elk antlers and velvet collapsed. Some elk farmers in the United States changed their operations to hunt farms, places where hunters could pay to shoot animals. The only legal option in the Yukon was the sale of elk meat, and that was not part of Danny’s vision of an educational preserve to showcase Yukon wildlife. He told a friend that the day he had to sell a pound of elk meat was the day he was out of business.

Elmer-1st and Danny especially favorite elk bull came from Chuck and Clara from California 1983 visit.

 

Fortunately, just at this time the Nowlans were approached by Holland America to provide a tourist attraction for the company’s bus tours. This was in line with Danny’s vision. He needed to upgrade the roads and fences, and acquire more northern species, but the Nowlans were still able to sell animals and care for the injured and abandoned ones that were constantly being dropped off at their door.  This change in direction was formalized by a change in name; the Yukon Game Farm became the Yukon Wildlife Preserve in 1989.

Original logo created by Peregrine Nowlan in 1989 when the name change occured from Yukon Game Farm. Later when the facility was sold and run as a non-profit the name remained and the logo updated to its current version.

Around 2000, Danny was once again faced with the serious problem of keeping the operation in business. Animal sales were still an option, but there was a dawning awareness in Canada of spreading diseases affecting wildlife. Danny needed permits to move animals across borders, and these became increasingly difficult to obtain. The matter came to a head for the Yukon Wildlife Branch when public attention was drawn to one of Danny’s mountain goats that appeared on a steep hill across the North Klondike Highway from the sod farm. Government officials were worried about the transmission of disease from domestic animals to wildlife, and two escaped mountain goats could have travelled past agricultural farms containing domestic goats.

Danny was unable to recapture his animals, and the Yukon government’s Philip Merchant came to the rescue with a helicopter and a tranquilizer gun. The story of the capture is a harrowing tale for another time, but no animal (human or goat) was terribly injured, and Danny was presented with the bill. 

Danny said, “I want to go fishing” and he started looking for buyers. He could have made a lot of money by letting a developer divide the Game Farm into acreages. Many Yukoners were reluctant to see this happen, and the Friends of the Yukon Wildlife Preserve was established in 2002. The Board of Directors included successful businesspeople, educators, and wildlife biologists who recognized the Preserve’s potential economic, preservation, and educational worth to the Yukon. The society tried to raise funds to buy and operate the facility as a business, and they received support from individuals and potential partners.

In July 2003, the Yukon Fish and Wildlife Management Board wrote a letter to support a proposal where a not-for-profit society would run the facility with assistance from the Yukon Government, as long as the facility obtained accreditation from the Canadian Association of Zoos and Aquariums. The government, for many reasons, was reluctant to commit to any involvement at that time, and the Board of Directors dissolved the Friends of the Yukon Wildlife Preserve association in August 2003.

There are many opinions about why the government persuaded a number of the original Friends and others to form an operating society, and then purchased the Yukon Game Farm in April 2004. Danny talked to the media and there was considerable public pressure in support of the sale. It was, and remains, a controversial decision especially for those opposed to seeing wildlife in pens. However, the Yukon Wildlife Preserve is a delight for children of all ages, and the expansive habitats created by Danny Nowlan make the residents very happy.

About his ability to get things done, Wendy Brassard says Danny would get these ideas and he wouldn’t abandon them. He wouldn’t just let them die or turn away from them. He’d think about it, he’d read because there was no Internet back then, he’d make phone calls, and the next thing you know, everything’s changed. And he just kept evolving. He was such a good example of ingenuity and resourcefulness, and never say die. Just if you think it’s right and it’s going to work and it’s a good thing? Do it.” David Smiley says Danny was an amazing character; that guy was different. Both good and bad. He had a rough side and he had a Grade 3 education. But he could develop a plan that somebody from a university would have trouble figuring out the nuances. He was a good planner. Randy Hallock concluded that Danny was interesting and always full of ideas. He just built the place and not much could stop him. He had ideas, and he made them work. People telling him ‘no’ just made him that much more driven.

David Mossop is involved with the Game Farm in its current form as the Yukon Wildlife Preserve. He says it’s interesting that all these years later, they haven’t changed anything. It’s basically exactly as Danny and Erika envisioned it – except brought to fruition a lot more. Their idea was to create something where the children of the Yukon could come and see the creatures that live here. And that’s basically what happened.

The memories that were collected during this oral history project speak to the impact that Danny had on so many friends, kids, and animals – and the Nowlans’ legacy remains intact for Yukoners and Yukon visitors. We think Erika would be proud to see a fully realized wildlife preserve with its visitation of wide-eyed children. Uli Nowlan often visits the facility and keeps a watchful eye on the operation. Danny didn’t become an avid fisherman, but he did relax knowing his animals, and his legacy, were in good hands.

The Humble Dzäna

The Humble Dzäna

The Humble Dzäna

8 minute read –

When welcoming folks to the Yukon Wildlife Preserve, us interpreters in the Front Cabin often say something along the lines of “you’ll find 10 Yukon animals here,” referring to the ones in our care and pictured on our map. But of course, so many other animals call the Preserve home too. Like the tsäl (sik sik/gopher/arctic ground squirrel) who are the 11th unofficial species that you can find above ground only in the spring and summer!

Another newer resident on the Preserve are the dzäna (muskrats). A mansion of a muskrat lodge has emerged in the moose pond over the past year and has remained visible even when covered by snow this winter! While guiding a bus tour recently, this seemling isolated home became the center of attention while we were looking for the elusive kanday (moose). The visitors and I mused “how many muskrats are in that thing?!” I did know a pair of muskrats had moved into the marsh a couple of years ago, and now maybe there’s a whole family living there hosting many parties (yes, I had to force that line so I can say that a group of muskrats are called a “party”). 

But while joking on my tour, I realised that I did not know much about this animal and this inspired me to dedicate some time to the humble muskrat.

Muskrats are often confused with tsà’ (beavers), and though they are very similar, they are not closely related at all. This is a neat example of convergent evolution: two animals may end up looking the same and acting in similar ways because of the shared environment that they live in. Both muskrats and beavers are semi-aquatic rodents, have water-resistant brown and sleek fur, build their lodges in shallow water or along the water’s edge, and forage on the surrounding plants.

When I told my partner that I was writing about muskrats, he made sure that I was including the story of muskrat’s heroic act. Growing up in Manitoba, we both learned about the special place the muskrat holds in Cree and Anishinaabe Creation stories.

Small details can vary with the storyteller but muskrat’s role remains the same. 

As written in his book Ojibway Heritage, elder Basil H. Johnston from Wasauksing First Nation begins the story with the Great Flood, where only the birds and water animals survived and Sky Woman came to rest on the back of a turtle. She asked the water animals to dive to the bottom and collect soil so that she can create land. Many animals – the loon, the mink, the beaver – dove down, down, down but none returned with soil. All seemed hopeless. Finally, the little muskrat softly said “I’ll go.” Everyone laughed as there was no way the tiny muskrat could make it to the bottom when all of the other animals had failed. Despite being ridiculed, the determined muskrat disappeared into the water and was gone for a long time. The animals and Sky Woman stared helplessly into the water until muskrat finally floated to the surface. Sky Woman lifted muskrat’s body onto the turtle and there, clutched tightly in muskrat’s paw, was a small clump of Earth. She took the Earth and spread it on the back of the turtle. The wind began to blow while Sky Woman and the animals danced together, spreading the Earth farther until it grew into Turtle Island. The animals celebrated and mourned together for without muskrat’s great sacrifice, Earth and all life would not exist. I personally like the story ending with Sky Woman breathing life back into muskrat’s little body so that he can celebrate too.

A traditional Anishinabe inspired Painting by: Carl Ray (1943 – 1979) of a muskrat. The Muskrat reminds us to be open to the creative possibilities of living in balance with Creation.

This story intertwines many moral and ethical values tied together with ecological knowledge. Muskrats are indeed very small, weighing only 2-to-4 pounds compared to the much larger 40-to-70 pound beavers. They are incredible swimmers and can dive underwater for 15-20 minutes at a time. When they dive, their heart rate slows and their body temperature plummets to help them conserve oxygen. Small hairs between their toes and their long, rat-like tail helps to propel them through the water. These are all helpful adaptations when you need to forage for plants and food all winter since muskrats do not store food like beavers. It’s no wonder that the small but mighty muskrat could swim to the bottom of the water with all of these traits.

Instead of building dams and lodges made from felling trees like beavers, muskrats build their lodge homes and feeding huts (called push-ups) out of plants like cattails, sedges, and reeds, packed together with mud. As in the story, their front paws are small with long claws for digging and holding building material, and their homes are shaped like the ball of Earth they held on to.

In the winter, you may see push-ups on frozen ponds and lakes. When the water begins to freeze, muskrats will chew a hole in the ice and push up clumps of material, creating an enclosed and insulated resting hut on top of the ice. Like ice fishing shacks on a lake, muskrats can pop out of the water and take a break from swimming long distances, have some lunch and take a breather all while staying protected from the harsh elements and predators.

These push-ups are also fast frozen piles of fresh plants that offer higher levels of protein, nitrogen, and other nutrients that are lacking in the low quality winter plants. These push-ups are great food sources for caribou, moose and bison and may help them make it through the winter with a nutrient boost. In the summer, waterfowl and marsh birds lounge and nest on the lodges, while snakes and reptiles use the muskrat tunnels and homes for places to rest and thermoregulate. I can’t help but think of muskrat’s desire and determination to help collect Earth as a parallel to the muskrat’s push-ups and lodges for providing food and shelter for other animals throughout the year.

Muskrats are also resilient and adaptable. They can have 2-3 litters per year with an average of 6 kits per litter making their population relatively resistant to disease, predation pressures, and they can survive through drought years by eating a variety of foods and getting water from the plants. Despite this resilience, there is emerging evidence that muskrat populations are declining across North America. The exact cause remains unclear for these declines, but a loss of critical wetland habitats and the connectivity between wetlands may have a large impact on populations.

I read this quote from elder Benton Banai that is fitting here:

 “No matter that marshes have been drained and their homes destroyed in the name of progress, the muskrats continue to grow and multiply. The Creator has made it so muskrats will always be with us because of the sacrifice that our little brother made for all of us many years ago when the Earth was covered with water.”

Muskrats play such an important role in the ecology of wetlands, Indigenous cultures and economic importance for trappers that we cannot overlook the muskrats and their habitat needs. One of the values that we can learn from the Creation story is that humans and animals are interconnected and living together harmoniously ensures the survival of all.

From the muskrat, we can learn to be determined and courageous when faced with a seemingly impossible task, to cooperate and help one another, to do acts not for the recognition but because it is the right thing to do, and to honour and respect all creatures regardless of their size. So the next time you visit the Wildlife Preserve, see if you could spot the small, humble, determined dzäna in the marsh. We can and do have a lot to learn from our wildlife companions.

The Curious Case of Dewlaps: Moose and Their Underappreciated and Mysterious Neck Accessories

The Curious Case of Dewlaps: Moose and Their Underappreciated and Mysterious Neck Accessories

The Curious Case of Dewlaps: Moose and Their Underappreciated and Mysterious Neck Accessories

10 minute read

When you think of a moose, you might picture an iconic Canadian creature with long legs, a majestic set of antlers, and the undeniable air of someone who really doesn’t care about traffic. What might not come immediately to mind is the subtle yet striking neck accessory that moose wear with… well, little to no fanfare: the dewlap. Yes, that’s right—moose, with their immense size and serene grace, sport a fleshy flap of skin dangling beneath their throat.

If you’ve ever had the privilege (or slight anxiety) of encountering a moose here at the Yukon Wildlife Preserve, or on a cross-country road trip, you’ve maybe noticed this particular feature. But what is it, and why does it exist? Let’s explore this underappreciated anatomical feature with a mix of scientific curiosity and the lighthearted humor it deserves.

What is a Dewlap, Anyway?

A dewlap is essentially a flap of skin that hangs from the neck, or throat of an animal and while it may seem like just an odd fashion statement, it often serves practical purposes. Dewlaps appear in all kinds of animals—like lizards, cows, chickens, rabbits, and yes, moose. Depending on the species, dewlaps help with everything from sexual selection, to staying cool to general communication. In moose, the dewlap isn’t just a bizarre fashion accessory, it’s also a multi-purpose tool in their biological toolkit – we think!

Fun Fact: a dewlap on a moose is also called a bell. If you’re a bird, that fold of skin is called a wattle. For rabbits, dewlaps are basically nature’s way of saying, “Congrats, you’re all grown up now!” Female rabbits flaunt these fluffy neck pillows as a sign of sexual maturity. Later, when they have babies, they even pluck the thicker fur grown here to line the nest. Birds and reptiles, on the other hand, can take it up a notch with their flashy neck frills—bright, colorful, and often retractable like the world’s fanciest pop-up tent, perfect for showing off in romantic or territorial drama.

But when it comes to ungulates, like moose, their dewlaps remain a mystery. It’s the unsolved cold case of the animal kingdom, stubbornly dodging scientific scrutiny. Nature can be funny like that sometimes.

Moose Practical Fashion: Is It About to Take Off?

Let’s address the most important question right off the bat: Do moose know they’re rocking a dewlap? Probably not. But if they did, we imagine it would make them feel pretty cool—like the one guest at a party with a trendy outfit no one else can pull off.  In the moose world, the dewlap is one of those things you don’t really see in everyday fashion. While antlers get all the glory in the animal kingdom, these enigmatic ornaments quietly steal the show in these hoofed animals. 

Moose, who roam the colder reaches of North America, use their dewlaps to help cool off in warmer weather. Male and female moose have dewlaps though their sizes differ considerably with, naturally, the male dewlap being larger than the females. The loose skin beneath their throat appears to expand and contract, and become more or less furry based on seasons which would help release heat from their bodies. This means that on a hot Yukon day (don’t worry, we don’t have too many of those), the dewlap might help prevent a moose from overheating as they browse lazily in the wild.

Moose September 2013 - Justine Benjamin. Cow and bull moose in rut season.

This statement might be contested by research from ungulates evaluated from Bro-Jørgensen given the need to thermoregulate (dissipate heat) is rather limited when you live in a more predominantly cold-climate than comparatively the eland antelopes of South Africa. Large ungulates like bison, elk, and yak do not present this caruncle; they may have evolved alternative, behavioural, cooling mechanisms that are less ‘cool looking’! But, wait, what about caribou? Technically, they fall under the 400kg threshold of the study and live in a cold climate and though they (males particularly) seem to rock the dewlap… sort of, theirs is more of a budget-friendly version compared to the moose’s deluxe mode.

(We’ll admit we’re pretty perplexed that both moose and caribou have flappy neck skin but wouldn’t be considered in the list of animals with evolutionary cooling mechanisms as they both are amazing swimmers, spending a lot of time in water and thus being able to cool themselves via this method—alas we will stick to moose necks!)  We appreciate that Bro-Jørgensen recognizes investigations into ungulate dewlap purposes has been left largely unexplored and for some reason, lizards have stolen all the scientists’ attention. 

Dewlaps and Courtship: The Moose Dating Scene

If you thought moose were all about antlers for impressing mates, think again. Dewlaps are also, or alternatively to thermoregulation, thought to be involved in courtship. During mating season, male moose seem to have enlarged dewlaps to make themselves appear more impressive. After all, what’s a little extra neck real estate if it helps you woo the ladies? This trait can also be found in male leopards—alongside aging the dewlap grows, similar to a lion’s mane thickening, scientists believe this growth helps in intra and inter-specific interactions—the important sexual selection kinds of interactions for attracting mates and staving off competitors.

 

 

Moose Bull Watson in Summer 2024 and Winter 2024 show a side view of the animal and its dewlap. It appears larger by possibly being more hairy in the winter for protection of the extra skin. In summer lighter and able to dissipate heat like its less hair covered ears in the summer.

In some species (like lizards), males will flare their dewlaps out to signal dominance or interest in a mate. While moose don’t exactly go full “show-off” mode with their dewlaps, the extra skin could play a role in their mating rituals. After all, being a moose isn’t all about looking tough with those antlers—it’s also about managing the subtler art of, well, neck presentation. 

These photos from young to old, left to right, are of Watson. We see from photos, the size of the dewlap appears to become larger over time. Bro-Jørgensen also explores the idea of the dewlap (in elands) being a detterent to predators as the side view makes the animal look larger and perhaps more intimidating. This would align with mature, genetically inclined animals having a larger dewlap. Though this was taken further and scarring on the dewlap was tested, exploring its advantages or disadvantages to protecting the common area of attack on prey by predators in some inter-species interactions.

A “Dewlap-umentary” Moment

Imagine a scene straight out of a nature documentary: A lone moose stands amidst the wild, its dewlap gently swaying in the wind as it scans the horizon. It’s a thing of beauty, really. But then, a rival moose appears on the scene—let the neck flap show begin! Not much behaviour present in ungulates, as seen in lizards and birds, but the moose may posture, showing off their large body size and then bam – side view of an impressive neck dangle and their rival runs away in fear – perhaps a convincing illusion.

So, the next time you visit the Yukon Wildlife Preserve and you catch sight of a moose strolling majestically past, don’t just look up at the antlers or marvel at their towering size. Look down (or, more accurately, look to the side) and take a moment to appreciate the dewlap. Despite all the brainpower spent pondering this, no one really knows why moose have dewlaps. Is it a fashion statement? A built-in scarf for chilly mornings? Who knows!

Since both male and female moose have them and they don’t seem to offer any major survival or dating perks, scientists think basically, ungulates got their dewlaps through evolutionary peer pressure, but not the same kind as lizards and birds. While birds and lizards are out there with their flashy, look-at-me neck bling for dating or drama, ungulates might’ve evolved their dewlaps for totally different reasons—like a mysterious club no one’s quite figured out yet. The dewlap might just be a leftover from moose ancestors—like a trendy accessory that’s fallen out of style but still hangs around (sciencey talk calls this a vestigial trait).

In the world of wildlife, the moose’s dewlap is mysterious, beautiful, and—if we’re being honest—just a little bit stylish. Who knew that this flappy neck skin would be so fascinating? Certainly not us. But we’re glad we found out. Wait, what exactly did we find out!?

An Impertinent Question – What is the dumbest animal on the Preserve?

The guest on my bus tour with the British accent began his comment, ‘this is an impertinent question, so you don’t have to answer it…

‘Oh’? I thought,

‘What is the dumbest animal on the Preserve?’ he continued.

We were at the Thinhorn rams with their big curly horns, and as if on cue, one of the older ones turned to us and gave us the most goggle-eyed dumbest look you could imagine. Everyone laughed and I didn’t have to answer.

But how about we flip that question and ask instead, ‘What is the smartest animal on the Preserve?’ 

First, one might ask, what is intelligence?  One definition of intelligence is the ability to adapt to new situations and to learn from experience. However, a little bit of research reveals that we can’t really answer which species is more intelligent than another. Animals are well suited to what they need for survival through instinct and physical adaptations, (instinct is behaviour oriented and is defined as; ‘an inborn impulse or motivation to action typically performed in response to specific external stimuli’. Today instinct is generally described as a stereotyped, apparently unlearned, genetically determined behaviour pattern. While we can identify faster learners and slower learners within a species we can’t readily compare the intelligence of different species. Personally, I cannot dam up a creek using mud and sticks and my bare hands but does that mean I am dumber than a beaver. I hope not.

We have learned that intelligence tests involving people can be culturally biased. Devising tests that try to fairly compare different animal species is even harder. In one test the animal subjects were required to learn a sequence of visual cues to receive a food reward. Monkeys learned quite quickly, rats more slowly. But rats have poor eyesight and when the cues were changed from visual to scented the rats learned as fast as the monkeys.

Even trying to compare dogs to captive wolves is problematic as a dog’s primary problem-solving tool is us. Ball rolls under the couch, get your human. Hungry, get your human. Need to go outside, get your human and so on.

Additionally, most animals have a good amount of persistence, especially when searching for  food. Hence the annual warnings from the conservation officers about the danger of having attractants in our yards in regarding bears. If, after weeks of trying, the fox finally manages to break into the hen house, is that persistence or intelligence or a combination of both? A captive wolf in a sanctuary during an experiment to test methods of non-lethal predator control challenged an electrified barrier 800 times! Now that’s persistence.

And if a captive muskox spends hours or even days ramming his boss (the flat bit of thick horn across his forehead) into a welded steel industrial gate separating him from the female muskox until it breaks; that is certainly persistent but is it intelligent? Nevertheless, the gates at the Preserve between the male and female muskox have been reinforced.

It is not difficult to suggest that predators probably have the most advanced ability to learn since their meals tend to run away and hide. They must continually adapt to fluid situations in order to eat. But the most amazing example of non-human learning I have run across is reported by Bernd Heinrich, author of, Ravens in Winter’, where he presented four groups of ravens with a puzzle consisting of pieces of meat hanging from strings.  One of the wild ravens, without having watched anyone else’s attempts, after pondering the problem for a period of time, flew straight to a perch above a hanging piece of meat, pulled the string up, put his foot on it to hold the slack and repeated the sequence until he had reeled in the piece of meat. First try.  Read the full account here

So, while they are not part of the Preserve’s collection, there are certainly ravens on the Preserve and they get my vote as smartest.
