“The mixing of the two species has even created hybrids with their own distinct sounds “
Are they two different species if they can mate and produce viable offspring?
An Ottawa study found that they are descended only from the wolves in that province, where there is a large national park surrounded by city.
Coyotes spread into the areas where wolves were searching for mates. The hybrid offspring had a wider diet, reduced food needs, more help for hunting and greater tolerance for the suburbia.
They’ve spread from there throughout the northeast, like Chicago.
Species can and do interbreed, but not all are viable. At some point they’ll distinguish them as a subspecies. There are already 19 subspecies of coyotes, Canis latrans, and 40 of wolves, Canis lupus. But do you add the new subspecies to latrans or lupus? An important legal distinction in the US where one can be hunted as a pest in many states., the other protected in many states.
