A Rescue Center for Small Wild Animals Looks to Place a Blind Moose Calf

July 19, 2025 By Ian Austen On Friday at Holly’s Haven, a wildlife rescue and rehabilitation center in a rural section of Ottawa, there was one coyote, two porcupines and more young raccoons and skunks than I could easily count. And in a makeshift habitat at the very back, there was a much larger animal: a blind moose with an injured leg that is about a month and a half old. Ava Potten is in charge of bottle-feeding Cedar. Ian Austen/The New York Times The arrival of Cedar, as the moose is known, has meant that Lynne Rowe, the center’s founder and director of operations, has had to learn a lot about the needs of young moose very quickly. But it has also created a particular challenge. Like all rescue centers, Holly’s Haven normally returns animals to the wild when they are old enough to cope or when they have recovered from their injuries. The best prognosis for Cedar is that he will recover very limited vision in his right eye, making a return to the wild a death sentence. But Cedar cannot follow the path set by Holly, a raccoon for whom the center is named and who lived there for years because brain damage made her release impossible. While Cedar weighs about 30 kilograms, or more than 65 pounds, he could reach 700 kilograms, or 1,500 pounds, as an adult. “All the experts I’ve consulted, veterinarians and moose rehabilitators, confirmed that he is not releasable,” Rowe told me as Cedar contentedly munched on dangling willow branches. “Young moose are heavily predated in the wild by coyotes, wolves. So he’d be extremely vulnerable.” (I recently wrote about the dangers moose and motorists face on Newfoundland’s highways, where North America’s tallest and second-largest land animal is an invasive species that has prospered.) On July 7, Rob Boisvert, a co-founder of a group called 269 Animal Rescue, was called by a friend who had spotted an injured young moose in a field east of Ottawa near the Quebec-Ontario border. When he arrived, Mr. Boisvert told CBC Radio, he began looking for the calf’s parent. “I don’t want to be the one that gets in between a mom moose and her and her son,” he told the broadcaster. But it soon became apparent, he said, that the calf was on its own. Because Mr. Boisvert does not hold a “wildlife custodian” license from the Ontario government, he contacted Rowe, who remotely supervised the move to the center next to their house, which sits on 10 acres of land. An enclosure was made largely out of steel fencing panels usually used for construction. And a large plastic wading pool became a substitute for the wetlands where moose spend much of their time. But before Cedar moved in, he was placed in an office with straw spread on the floor where Ava Potten, a student working for the center this summer, comforted him. “He was definitely stressed out,” Ms. Potten, who is now in charge of bottle-feeding Cedar, said. “But he fell asleep on me.” Cedar is unlikely to recover full vision. Ian Austen/The New York Times The large infection on Cedar’s right hind leg appears to be responding to antibiotics. Rowe and Ms. Potten excitedly noted on Friday that Cedar was applying his full weight on it. An ophthalmic veterinarian told Rowe that there was no hope that sight would return to Cedar’s left eye, which is completely clouded over. But there is a chance that the moose may regain partial vision in his other eye. The cause of the injuries remains unknown, although Rowe said that all of the veterinarians agreed that Cedar had suffered some sort of trauma to his eyes and leg. Rowe now has a plan for Cedar. The Toronto Zoo, Canada’s largest, has a large moose enclosure but no moose. The last pair died, effectively from old age, earlier this year. But when it comes to animals found in Canada that are not in an endangered species recovery program, the zoo now exhibits only animals that, like Cedar, cannot live in the wild or were born at the zoo.

‘No end in sight' for systematic killing of BC wolves to save caribou

CANADA'S NATIONAL OBSERVER

BC's most recent five-year wolf cull is set to expire with no indication the province has plans to end the controversial measure that doesn't support the long-term recovery of caribou, say critics.

Please also read my article from some years ago. 

"According to a new study – there’s simply no proof that wolf culls – aimed at saving western Canada’s endangered mountain caribou – are working." 

Beavers are the unsung heroes of wildfire prevention

Beavers are the engineers of the forest. Best known for chewing down trees to build up dams, the animals change their surroundings in obvious ways: pointy stumps lie in their wake; piles of branches and mud peak over riverbeds. However, scientists are increasingly noticing another, less evident way they shift their environment: wildfire prevention.

New research reveals incredible hunting secrets of the Great Grey Owl

A new study in Manitoba shows how the “Great Gray Owl,” a common site, either soaring over the plains and perching and nesting in the forests of the eastern Canadian prairies, overcomes many obstacles to find its prey.

  The prairie vole (Microtus ochrogaster) - Photo by Soebe, public domain

The bird is able to "punch" through as much as 50cm (20”) of hard, crusty snow - enough to hold a person’s weight - to catch a vole hiding beneath. (The vole is a small rodent which frequently serves as a meal for the winged predator.)

                       

But the snow presents the owl with other problems way before the “moment of capture,” too. Not only does it hide its prey from site, forcing the bird to rely on its hearing only, it deadens, or attenuates any sound the vole is making, and even "bends" or refracts it, creating an “acoustic mirage,” or false impression of its location. (See above.) The denser the snow, the more pronounced is both the attenuation and refraction. 

The owl soars towards its prey from its perch (above), then hovers as directly over it as it can until it reaches a “listening position” of least refraction and attenuation - defeating that "acoustic mirage" in the process. Then it plummets straight down on its target, forming a “plunge-hole” in the snow.

The owl is superbly adapted for this. While it has no ear tufts, it has the largest “facial disc” of any owl. That's where its ring of feathers filters and amplifies sound at its ears. (See above) This also allows it to pick up low-frequency sound, the kind that transmits best through snow. And its wing feathers are formed in such a way as to allow it to fly and hover more quietly than just about any bird, anywhere.

There are other features that make the “Great Gray” unique, too.

It is the largest owl in North America, with a wing span of well over a metre. It can be found across the province, year-round. And, since Manitobans “adopted” it in 1987, it’s been our official, provincial bird, too!

A three-member team, two from the US, along with James Duncan from “Discover Owls” in Balmoral, Manitoba, used loudspeakers and special cameras in their research.

The above images were extracted, with thanks, from the team's official study, just published in the proceedings of The Royal Society.

Scientists Find Oil Rig Noise Pollution Affects Birds

We need to rethink the way we regulate noise pollution from oil rigs as the noise from oil drilling can be harmful to prairie songbirds, including species that are at risk. These findings come from a new study authored by Nicola Koper and Patricia Rosa. Koper is a professor at the natural resources institute at the University of Manitoba and Rosa is an assistant professor at St. George’s University. They both study how human activity can interfere with songbird behaviour. Story here.

After maturing at sea, Chinook Salmon on Canada's West Coast swim back to their natal streams to spawn. Twenty-eight populations of Chinook Salmon live in Southern British Columbia, each with different habitats and survival strategies. Chinook Salmon face many threats in both fresh and saltwater, including climate change and detrimental effects from hatchery fish. At the current meeting, COSEWIC considered the 12 populations of Chinook Salmon most impacted by hatcheries: four were designated Endangered, three Threatened, and one Special Concern, while one was deemed Not at Risk. Three remote populations were determined to be Data Deficient, and will require additional research before being re-assessed. Details here.

Snarl for the camera! An international team of scientists and software developers use facial recognition technology to identify individual grizzlies in the wild.

 By Larry Powell

An adult female grizzly (Ursus arctos). "BearID," as the program 

is called, captures a bear’s face in a photo image, rotates, 

extracts and embeds it in order to classify the individual.  

Facial recognition techniques have long been used to identify primates, including humans. But, up 'til now, there's really been no effective way of identifying wild species like the grizzly (brown) bear who, unlike the zebra or giraffe, lacks unique and consistent body markings.

     

In co-operation with two US software developers, four scientists from the University of Victoria bought their idea to reality. They tested their system on grizzlies at two locations - Knight Inlet, BC, and Katmai National Park, Alaska. After taking thousands of pictures, they were able to positively identify 132 individuals with almost eighty-four percent accuracy.

The technology enables wildlife monitoring on larger scales and in higher resolution than before. And it can be applied, not only to the grizzly, but to many other mammals, as well. This, in turn, could allow conservationists and lawmakers to tackle global challenges such as biodiversity and habitat loss.

Knight Inlet, one of the two locations for the research, is home to a First Nations Lodge where bear-watching forms part of the local eco-tourism industry. 

A band official there, Dallas Smith is impressed with the results. 

“This amazing technology will help us identify individual bears and better understand their movement and interactions throughout our territories, which will enable us to build better management plans around habitat protection. It will also help us manage and mitigate the impact of wildlife viewing, as well as positioning ourselves to more effectively and efficiently deal with bear-human conflicts that are becoming more and more prevalent.”

These new ways of using facial recognition technology, referred to as a "deep learning approach," were published recently in the journal, Ecology and Evolution.

Animal behaviour: Leading the young: older male elephants prove they are "up to the tusk!"

Journal: Scientific Reports

Older male elephants may have important roles to play as experienced leaders to younger males when navigating unknown or risky environments, according to a study published in Scientific Reports. 

In long-lived species, such as elephants and whales, older individuals often respond more appropriately to complex, changing environments, which may benefit younger group members. However, research in this area has tended to focus on females.

Connie Allen and colleagues investigated grouping behaviour and patterns of leadership in 1,264 male African savannah elephants travelling on elephant pathways to and from the Boteti River in the Makgadikgadi Pans National Park (MPNP), Botswana.

The authors found that lone elephants accounted for 20.8% (263 elephants) of sightings on elephant pathways. Adolescent males travelled alone significantly less often than expected, unlike mature adult males who were more likely to travel alone than expected, which may suggest that lone travel is riskier for younger, newly independent and less experienced individuals. Older adults were significantly more likely to travel at the front of groups of males, suggesting that mature adult bulls act as repositories for ecological knowledge and that they may be important leaders during collective movement in all-male groups of African savannah elephants.

Old males being considered reproductively redundant is commonly used as an argument to support the legal trophy hunting of old males, according to the authors who suggest that such selective harvesting of older males could disrupt the wider bull society and the inter-generational flow of accumulated ecological knowledge.

New research suggests, zoos and aquariums in Canada do little to protect endangered creatures in the wild.

A study just published in the journal, Facets, begins positively enough. It acknowledges that members of Canada's Accredited Zoos and Aquariums (CAZA - the private, non-profit charity representing thirty such institutions), do try to be leaders in researching this field and, that they do take part in programs aimed at species survival by breeding animals in captivity, then re-introducing them into the wild.

And on its own website,  CAZA claims, "We are behind some of the most remarkable conservation success stories. This includes, bringing species such as the Black Footed Ferret and the Vancouver Island Marmot back from the brink of extinction,” for example. 

However, in some key areas, the researchers (a team of two biologists from Laurentian University in Sudbury) suggest, CAZA and its members are falling short. 

Zoos and aquariums could be "important resources in mitigating biodiversity loss. And the credibility of zoos as conservation organizations can only be enhanced by the production of peer-reviewed science in this field."

Yet, while CAZA members are turning out more such research (still significantly less than their US counterparts and most in "zoo-centric" journals), most are not on the topic of biodiversity conservation at all, but on veterinary science, instead. 

"Few studies have explored their contribution to biodiversity conservation efforts and research productivity in general." 

Increasing collaboration with academic institutions would be one way for CAZA to overcome that shortcoming. So, “It is puzzling that collaborations between these groups are rare. Academics can use the unique environment zoos and aquariums provide for studying species, whereas academic research based on field observations may increase the success of reintroduction efforts led by zoos and aquariums.”

This new research comes to light against the backdrop of extinctions hanging over tens of thousands of Earth's wild species, “ due to widespread degradation of global ecosystems caused by humans.”

The hand of man shows through once again in a major weather catastrophe.

 by Larry Powell

A new study finds, manmade climate change did, indeed, worsen the bushfires which ravaged much of southeastern Australia late last year and early this year. An international team of seventeen scientists has just concluded, the probability of conditions developing like the ones which kindled the catastrophic blazes “has increased by at least 30% since 1900 as a result of anthropogenic climate change.” 

And that figure could be much higher considering that extreme heat, one of the main factors behind this increase, is underestimated in the models used. The heating of the planet, largely due to human extraction and burning of fossil fuels, has, for some time been shown to be the main factor behind the development of storms that are more intense and frequent than before.

Looking to the future, the study predicts, if the temperature rises 2 ºC over 1900 levels, the kind of fire risk which existed during the recent bushfires "will be at least four times more likely." 

Last year was both the hottest and driest in Australia since records began around 1900. Not only were the fires more frequent and intense, they started earlier than usual. They claimed the lives of more than a billion wild animals, thousands of livestock and 34 humans. Almost six thousand buildings were destroyed. And the smoke - which produced air quality hazards some 20 times beyond what were considered levels safe for humans - lingered for months over much of the country.

To quote from the report, "It is well-established that wildfire smoke exposure is associated with respiratory morbidity. Additionally, fine particulate matter in smoke may act as a triggering factor for acute coronary events (such as heart attack-related deaths) as found for previous fires in southeast Australia. Increased bushfire-related risks in a warming climate have significant implications for the health sector."

The research was done by the scientific group, “World Weather Attribution” (WWA). It's a relatively new, international effort to analyze and communicate the possible influences of climate change on extreme weather events.

The more we carve up natural landscapes with roads and fields, the closer we’re pushing large predators like lions and wolves, toward extinction.

by Larry Powell

While the consequences of habitat loss have been known for some time, new research just published, underlines just how grave the situation has become. 

While this latest research is German, animals like the grey wolf face similar disruption in North America.

While this latest research is German, animals like the grey wolf face similar disruption in North America. 

It’s called “habitat fragmentation.” And, it’s been happening on such a large scale, it’s been hard to tell what aspects are the most destructive. That's because ecologists - at least 'til now - haven't been able to properly keep track of all wildlife within an entire eco-system when human developments confine them to smaller and more isolated patches of livable space.

Under Republican and Democratic presidents from Nixon through Obama, killing migratory birds, even inadvertently, was a crime, with fines for violations ranging from $250 to $100 million. The power to prosecute created a deterrent that protected birds and enabled government to hold companies to account for environmental disasters. But in part due to President Donald Trump’s interior secretary nominee…more here.
