The grizzly bear (Ursus arctos horribilis) is a sub-species of brown bear, most commonly found in western North America. Their ancestors came from Eurasia only around 50,000 years ago, which is not enough time to develop any major differences from their European and Asian cousins. Grizzlies vary in size depending on the location of their habitat, and therefore diet .
A grizzly that lives in Alaska or Canada will be larger that a grizzly living in the Rocky Mountains or the Yellowstone National Park because of the amount of fish – the bear’s primary source of protein. In other regions, vegetation, carrion and rodents are a much bigger part of their diet. In Yellowstone’s case, the park has seen the introduction of the grizzly’s long time hunting rival – the gray wolf. Coyotes, foxes and wolverines may compete with the bear for smaller prey, but they are more pests than rivals.
The more herbivorous black bears are not a threat to the grizzly. In fact, they can sometimes be the prey. When grizzlies venture into black bear territory in search of food, the latter usually run away, only defending themselves if the grizzly is young or there is no other option.
