There is at least one confirmed observation of a grizzly bear digging out, killing, and eating a black bear when the latter was in hibernation. In addition, we're leading the charge to make sure climate change is not only addressed, but also that wildlife managers are able to assure that habitats that change in response to climate change remain adequate to sustain grizzly bear populations. Grizzly Bear (Ursus arctos horribilis) | U.S. Fish & Wildlife Service Grizzly bears overlap with Black Bears in range, but there are numerous factors that can differentiate the two.
