grizzly bear

noun

: a very large brown bear (Ursus arctos) of northwestern North America

Note: The grizzly bear is the same species as the brown bear, but grizzly bear is typically used for the North American brown bear and not the European or Asian brown bear. In the U.S., grizzly bear is most often used for a brown bear of inland habitats (as in Montana and western Canada) that is typically smaller than coastal brown bears and usually has lighter-colored tips on the fur. The grizzly bear is often considered a subspecies (Ursus arctos horribilis) of the brown bear and, especially formerly, a separate species (Ursus horribilis).

The brown bears of Kodiak Island, the grizzly bears of the Rocky Mountains and interior Alaska, the European brown bear, all are now considered to be the same species, Ursus arctos, despite tremendous variation in color, size, and habits.Natural History
