Meet the coywolf: A newly emerging species is behind the brazen attacks in Durham
Toronto Star ^ | August 15, 2009 | Carola Vyhnak

Is it a coyote? Is it a wolf?

Yes and yes. It's a "coywolf."

The predators that are plaguing Durham Region and showing up in urban areas appear to be an emerging species resulting from wolves and coyotes interbreeding.

The larger, highly adaptable animals "have the wolf characteristics of pack hunting and aggression and the coyote characteristics of lack of fear of human-developed areas," says Trent University geneticist Bradley White, who's been studying the hybrids for 12 years.

We're seeing "evolution in action," he says.

But that combination of genetic material from both species has spelled trouble for farmers, who are losing a growing number of livestock to predators.

They report attacks by animals that are bigger, bolder and smarter than regular coyotes. They say hunting in packs to prey on sheep and cattle in broad daylight is becoming a common behaviour.

Durham Region farmers have suffered the most damage to livestock in the province. Last year the food and agriculture ministry paid out a total compensation of $168,000 in the region for 545 dead or injured animals.

Commonly called eastern coyotes, the creatures are actually a mixture of western coyote and eastern wolf that comes from a constantly evolving gene pool, says White, chair and professor of biology in Peterborough.

Going back 100 years, deforestation, wolf control programs and changing habitat, ecosystems and prey conspired to drive down the wolf population. Meanwhile, the number of coyotes – whose original range was in western North America – grew, thanks to their ability to adapt and reproduce with ease. The two species started to interbreed, White explains.

"In many ways, this animal is a creation of human impact on the planet," says White.

Although the coywolf hybrid has only recently been verified through genetic research, White believes they started appearing in southern Algonquin Park back in the 1920s.

Colleague Paul Wilson, a wildlife genetics specialist, says the genetic gumbo from which coywolves emerge produces some that are more wolf-like, while others have more coyote characteristics. But they're definitely bigger.

"Some of these are 80-pound animals, double the size of a typical coyote that used to be 40 pounds."

But there's no cause for alarm, says John Pisapio, a wildlife biologist with the Ministry of Natural Resources, which is studying the role of coyotes and wolves in the ecosystem.

Hybrids may be larger but there's no evidence the population as a whole is more aggressive or prone to aberrant behaviour, he says.

He agrees predation on livestock is a concern – they do kill sheep and smaller animals – but insists attacks on cattle are unusual.

"As a biologist I find it hard to explain how a coyote brings down a 900-pound steer."

In some cases, coyotes might just be feeding on an animal that died from other causes, he says.

The population growth is a natural upswing following a mange epidemic that wiped out big numbers eight or nine years ago, he adds.

Pisapio says instances of fearlessness or brazen attacks are usually the result of coyotes that have come to associate food with people and lose their natural fear of humans.

That belief is echoed by Johnny, "The Critter Gitter," who didn't want his last name used because people don't like that he kills problem wildlife for a living.

"I kill coyotes. I don't sugarcoat it," he says.

But he feels sympathy for them.

"Humans are to blame for making monsters of them," he says. Coyotes are attracted by pet food and garbage left lying around in urban areas, and deadstock on farms.

They're not all bad and often get the blame when dogs kill livestock, he says. Johnny also doubts they're making a regular meal of cattle. During the 30 years he's worked in the province, he's seen only a few cases of "large, healthy animals taken down by coyotes."

But as coywolves become more urbanized and their relationship with people continues to evolve, city dwellers can expect problems, says White, suggesting a control program may be needed at some point.

"They will clearly bump into human activities, and there will be pets eaten in Rouge Valley."

One of the major reasons coyotes extended their range was the extirpation of the gray wolf. As a rule, wolves kill abny coyote they find in their pack range. I read that since the re-introductioon of the wolf in Yellowstone, the coyote population has been halved.

Yes and yes. It's a "coywolf."

"Coywolf" sounds girly. It's a Wolfote!

Yep, I think wolfote is more appropriate too, especially because it’ll be a more dangerous animal than a coyote.

It is likely that they would even take the human’s weapon into account in their strategy. Any area where these animals are sighted should be placed off limits for foot travel until they can be eliminated.

I'm not buying your tale but I guarantee that you would love this book.

I think the guy is talking about unarmed idiotic nature-naive foot travel.

Saying that wolves, coyotes, and dogs are all separate species is a mistake. If they interbreed and produce viable offspring, they should be considered members of the same species.

I agree, they should be subspecies.

The econuts never talk about the way wolves (or these predators) bring down their prey by hamstringing then starting to devour that animal while still alive even though it’s part of nature and survival.

Oh some of them do, but even though these same econuts see us as just another animal (I disagree) in their totally materialistic world (i.e. no supernatural) they figure we somehow can't humanely hunt and kill an animal for food ourselves. rational disconnect there...

Coyotes truly are evolving into more intelligent predators, particularly in the area of searching and stalking prey

Yes this is evolution. It's just not the form of speciation with which you're familiar. It's much more common in plants than animals but certain genera (and genus Canis is one of those) produce new species this way.

I agree and it’s uncanny how they have adapted to living among man, even in our cities and very seldom being seen by us.

Good point...I believe the vast majority of the AR and eco crowd would have us all be vegans or at least vegetarians and not be concerned in the least about the inferior animals eating each other.

""As a biologist I find it hard to explain how a coyote brings down a 900-pound steer."

I wonder where he got his biology degree...

...he needs to sue the faculty for malpractice.

The latest research reveals that every sub- species of wolf that has ever walked north america were different variations/percentages of admixture of coyotes and gray wolf that naturally developed in their own region’s. Red wolf-western wolf-rocky mountain wolves-mexican wolves- timber wolves -algonquin wolves ect..... the lone true wolf on the continent is the gray wolf.and they to got larger up north as there evolution required them to in order to kill larger game.both evolution and breeding plays factors but crossbreeding is natures fastest way.this coywolf influx is natures way to fill the void in the eco system where there have been an absence of wolves
