Coywolves are omnivores. They're opportunistic hunters who will feed on everything from berries and seeds to small mammals like mice, voles, squirrels and rabbits. Their large jaw structure allows them to hunt larger mammals like deer, which in spring, is the main thing they eat. Talk of “coywolves” – a blend of coyote and wolf – is everywhere. There is a PBS special called Meet the Coywolf, a recent article in the Economist, and it is now trending on Facebook. The media. The coywolf, a mixture of western coyote and eastern wolf, is a remarkable new hybrid carnivore that is taking over territories once roamed by wolves and slipping unnoticed into our cities. Its. Your field guide to everything you ever wanted to know about the Coywolf, or Eastern Coyote — from a trip through the Coywolf’s modern day habitat to its very recent evolutionary history. Designer. The coywolf is a hybrid species containing DNA from both coyotes and wolves. (Image: © Jon Way | Eastern Coyote/Coywolf Research) The coywolf is a coyote-wolf hybrid found throughout eastern North. In Cape Breton's Cl Quali and rugged landscape, Canid specialist Simon Gadbois is trying to assess coywolf population numbers. Pozzovivo hybrids. And I don't like that. So, we've just tried to get a look at this guy, and he was back and forth like a rocket, which is great.

Simply put, every coywolf is different. Some have more coyote, some more wolf, and everywhere in between. They have been known to roam the streets of Washington, Boston, and even New York City, where they use abandoned subway lines to travel freely.
Gray wolf populations plummeted in North America upon the arrival of European settlers. Wolves were hunted as pests, and the clearing of their habitat for farmland had a tremendous impact on their numbers.
By the end of the s , grey wolves were almost entirely extinct in the United States. Some scientists are even going as far as sterilizing coyotes in areas where the critically endangered red wolf lives.
Interbreeding is destroying the genetic integrity of these wolves, whose numbers in the wild have dwindled to about The first coyote-wolf hybrids have been traced back to the year , when western coyotes migrated from the American Southwest all the way to Ontario, Canada.
It was there coyotes first came into contact with eastern wolves, and nature took its course. From Algonquin Provincial Park, the descendants of these animals spread throughout the east at a remarkable speed.
They have continued to spread to this day, and their range now takes them from Canada to the Mid-Atlantic states. Likewise, gray wolf Y chromosomes have also been found in a few individual male Texan coyotes.
The resulting hybrids would later on melt back into the coyote populations as the wolves disappeared. However, the same study also discussed an alternative possibility that the red wolves, which in turn also once overlapped with both species in central Texas, were involved in circuiting the gene flows between the coyotes and gray wolves, much like how the eastern wolf is suspected to have bridged gene flows between gray wolves and coyotes in the Great Lakes region, since direct hybridizations between coyotes and gray wolves is considered rare.
In , the U. Using gray wolves from British Columbia and western coyotes, they produced six hybrids, making this the first hybridization case between pure coyotes and northwestern wolves.
The experiment, which used artificial insemination, was intended to determine whether or not the sperm of the larger gray wolves in the west was capable of fertilizing the egg cells of western coyotes.
Aside from the historical hybridizations between coyotes and the smaller Mexican wolves in the south, as well as with eastern wolves and red wolves, gray wolves from the northwestern US and western provinces of Canada were not known to interbreed with coyotes in the wild, thus prompting the experiment.
The six resulting hybrids included four males and two females. At six months of age, the hybrids were closely monitored and were shown to display both physical and behavioral characteristics from both species, as well as some physical similarities to the eastern wolves, whose status as a distinct wolf species or as a genetically distinct subspecies of the gray wolf is controversial.
Regardless, the result of this experiment concluded that northwestern wolves, much like the eastern wolves, red wolves, Mexican wolves, and domestic dogs, are capable of hybridizing with coyotes.
In , a research team from the cell and microbiology department of Anoka-Ramsey Community College revealed that an F 2 litter of two pups had been produced from two of the original hybrids.
At the same time, despite the six F 1 's successful delivery from the same coyote, they were not all full siblings because multiple sperm from eight different northwestern wolves were used in their production.
The successful production of the F 2 litter, nonetheless, confirmed that hybrids of coyotes and northwestern wolves are just as fertile as hybrids of coyotes to eastern and red wolves.
Both the F 1 and F 2 hybrids were found to be phenotypically intermediate between the western gray wolves and coyotes.
Unlike the F 1 hybrids, which were produced via artificial insemination, the F 2 litter was produced from a natural breeding.
The study also discovered through sequencing 16S ribosomal RNA encoding genes that the F 1 hybrids all have an intestinal microbiome distinct from both parent species, but which was once reported to be present in some gray wolves.
Moreover, analysis of their complementary DNA and ribosomal RNA revealed that the hybrids have very differential gene expressions compared to those in gray wolf controls.
Hybrids between coyotes and domestic dogs have been bred in captivity, which dates to pre-Columbian Mexico. Domestic dogs are included in the gray wolf species;  hence, coydogs are another biological sub-variation of hybrids between coyotes and gray wolves; the dog being considered a domesticated subspecies of Canis lupus.
