The Patience of a One-Eyed Owl

The Patience of a One-Eyed Owl

It is dusk turning to night, with darkness enveloping the forest. Stationed in a tree on the side of a road hides a predator, whose yellow eyes reflect with the passing headlights of cars driving by. This owl is currently listening, not only to the engines of vehicles and the sounds of gravel being kicked into the air, but for tiny rustling in the underbrush across this treacherous path.

The ‘great horns’ on this owl are not their ears; instead, they have an opening on both sides of their head to take in the sounds bouncing off the facial disc of feathers around their face. One of these openings is slightly higher on their skull, allowing for the sounds of this noisy prey to enter one ear a fraction of a second faster than the other. As this owl twists their head, they finally pinpoint the location of their prey, following with their eyes to the exact location the creature is hiding. As they zone in and begin to take flight, all sounds except for the scurrying prey begin to fade. The great horned owl narrows its eyes on their target, taking in the flow of air around their silent wings whilst beginning the slight movements they need to grasp with their talons.

All of a sudden, in this brief moment of time, a life is imperiled; a flash of light enters the owl's vision from their right side and the world goes blacker than the night they surround themselves in.

The road is a deadly location for many animals; vehicles can collide with wildlife passing through, garbage and trash commonly finds itself on its side, and carnivores often use these areas to hunt those animals taking advantage of the weedy species growing in abundance. Not only do predators hunt those in the underbrush, but they also find themselves on the sides of roads waiting for foolish prey to cross the area with no cover.

A great horned owl that has recently entered our rehab center was one such predator. When they were first admitted into our charge, our animal care team was told by rescuer Sonya Bingley that they were struck by a car, north of Braeburn, resulting in difficulty flying and their right eye remaining swollen shut.

After some brief examinations led by the veterinarians at AlpineVet and initial attempts at feeding, the owl was visually responding to our team's actions using their left eye, but had a lack of ferocity that is normally expected from birds of prey. The intake exam looked at the owl’s entire body, determining that the only major injury was to their right eye.

As there was most certainly head trauma, the lights were kept low while we gave them pain medication and encouraged them to eat. During this process they were extremely patient with being handled, prodded, and even picked up in their entirety. The meals they would eat were few and far between, and the rare times that they would flap their wings were when being picked up too briskly. Alongside this, their ability to balance when being picked up or placed down was lacking, often resulting in the bird tumbling when attempting to walk. 

When the owl was initially received and the intake examination was concluded, a closer look at their right eye was needed, noting that it was swollen shut upon arrival. After opening the eye to get a brief look, both eyes were responsive to light and continued to be for multiple days in our care. Their right eye became less swollen as the days passed, however the owl kept squinting and their attitude remained dull with continuing signs of pain. Alongside this, the eye itself continued exhibiting changes each day, with signs of haemorrhaging and debris floating in front of the pupil, likely from a tear in the iris. Eventually the right eye lost its ability to react to light, and the owl was taken into another examination with AlpineVet, determining that the eye was now non-visual.

Having concerns about a raptor being released into the wild with a single eye, inhibiting a key sense that they use to hunt, talks of all kinds were happening behind-the-scenes regarding eye surgery and the potential hazards of removing their eye completely.

Eventually, the preserve decided to reach out to experts in the field of raptor rehab in BC, an organization ironically known as OWL. The call we had was extremely informative, and we asked a few questions regarding the owl’s lack of hunger, balance, and whether or not a single-eyed owl could possibly be released successfully.

Their response eased our fears, they have had cases exactly like this one, and not only were owls with one eye common in their rehab center, they were also great candidates for successful release into the wild.

For owls struck by vehicles, eyes are commonly injured and need removal; however, through this call we found out that surgery to remove the eye is almost never necessary. Prior to this, we knew of two options for eye surgery that worked for owls: enucleation, the process of completely removing an eyeball from its socket by severing its connections with the brain; and evisceration, where the cornea of the eye and all of its inner contents are removed, leaving the sclera (white, fibrous outer shell of the eye) intact.

In terms of the successful release of an owl back into the wild, evisceration has a better success rate as that surgery minimizes the disruption to the owl’s facial disc. The facial disc of an owl is the concave formation of feathers around their face that directs sounds into their ears, which is what allows them to continue hunting prey in 3D space even when one eye is missing. However, through our call with OWL we learned of a third option for eye removal, simply leaving it.

Owls are able to allow their damaged eyeball to naturally degrade whilst in its socket, eventually making the orbital empty whilst not disturbing the fragile feathers around the owl's facial disc. With three options presented to our animal care team for handling this eye-boggling problem, we continue to weigh our options whilst allowing the owl to regain their strength. They have made incredible progress thus far but still need to recover from their injuries, work their flight muscles out, and try hunting live prey before we release them. Of course, plans for rehab always seem easier at the beginning, and many things can go awry; but we will continue to play it by ear as situations arise.

With patience, we hope this owl will recover slowly but surely, gaining their vigour and ferocity back so we can reintroduce them into the wild.

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.

Bonaparte’s Gull Release

Bonaparte’s Gull Release

by Lindsay Caskenette | Jun 25, 2024

4 minute read - 

A Bonaparte's gull was brought into the Wildlife Rehabilitation Centre at the Yukon Wildlife Preserve after it was found flightless on the side of the road. The bird has no significant injuries, some feather damage and was likely concussed. A short time in the centre to recover, eat fish and get strong meant a successful release of the animal to Tàa'an Män — Lake Laberge on the traditional territory of the Ta'an Kwach'an Council.

Old Crow Bald Eagle

Old Crow Bald Eagle

by Lindsay Caskenette | Jun 12, 2024

1 minute read - 

In the remote, fly-in community of Old Crow, on the Traditional Territories of Vuntut Gwitchin First Nations a juvenile bald eagle was found by Robert, at the dump, flightless and injured. The eagle was coaxed into a crate and eventually brought to the Yukon Wildlife Preserve after it made a stop in Dawson and caught a flight via Air North.

The bald eagle, thak tth'ak came to the Preserve's Wildlife Rehabilitation Centre on May 10th underweight (4.3kg) and with a OD (medical term for right eye) chronic corneal ulcer.

Likely a she, given the large size of the animal. She has gained sufficient weight, coming in at 4.83kg. She has been viewable in the aviary as she works to build up flight muscles. Now she is ready for her public release back to the wild this Friday. She has a cloudy eye but has been successful catching live food and as a predominantly scavenging animal she is likely to do quite alright back in the wild even with this limitation.

She will not be returned to Old Crow due to the long travel and stress concerns related to transfer. Instead, she was released outside of Whitehorse on Friday June 14th at 7pm. 

Around 40 people joined the event to send off the bird. Thank you to everyone who joined the release, it was a perfect evening. The sky welcomed us all without a drop of rain. Thank you to all who provided good vibes and sent off the eagle with strength and grace.

Thank you to Wylie, Corrine, and Thay K'i Anint'l for the prayer and blessing for this bird's return to the wild and resilience for a long eagle life. 

Thank you to everyone who helped this Eagle along its path to recovery. To Robert K who found the bird and ensured it got a second chance at life. To Norma, to the team at the Preserve that helped with the bird release event. To Air North for giving the bird some helping wings South to the Rehabiliation Centre.  Thank you, Masshi, Gunalchîsh????

She took her time deciding to soar but this allowed everyone to share in more details of her story, to practice patience and to grow our appreciation of her and others' incredible story of resilience.

The beginning of June the Preserve welcomed a visitor who had, and later shared with us, an extraordinary experience with the eagle while it was recovering in the aviary. 

She shared with us the following:

I felt a very special spirit from her. A very conscious and intelligent bird.
I heard she didn't have a name. 
Horus came to mind for me because of her eyes and her mystical spirit.
"Horus, in ancient Egyptian religion, a god in the form of a falcon whose right eye was the sun or morning star, representing power and quintessence, and whose left eye was the moon or evening star, representing healing."
"Horus, in ancient Egyptian religion, a god in the form of a falcon whose right eye was the sun or morning star, representing power and quintessence, and whose left eye was the moon or evening star, representing healing." The old crow bald eagle was given and unofficial name by a visitor, Jasmine Colomby who also drew and shared this interpretation.

Help us get them back on their wings. We could use your help. If you are able to support the care of these two animals, please consider donating. Every contribution makes a difference and as a non-profit charitable organization, you can receive a charitable tax receipt for your support.

Brittney joined the Wildlife preserve in the summer of 2023. Growing up on Northern Vancouver Island, surrounded by the temperate rainforest, nature and animals have always been a part of her life. It exploded into a passion, when she started her dog walking business in 2017 and she began spending 6-7 days a week in the forest, rain or shine! This sparked an even deeper appreciation for the cyclical nature of the land and how all of the plants & animals work together symbiotically. She is forever ‘that girl’ on the hike, pointing out different rocks and plants, explaining their origin or what they could be used for medicinally. Brittney and her dog Cedar relocated to the Yukon to help care for 31 sled dogs. She is so excited to expand her local knowledge as a part of the Preserve team.
