Grizzly Bear, North America

The grizzly bear  is any North American subspecies of the brown bear, including the mainland grizzly, the Kodiak bear, the peninsular grizzly (U. a. gyas) and the recently extinct California grizzly  and Mexican grizzly bear. Specialists sometimes call the grizzly the North American brown bear because the grizzly and the brown bear are one species on two continents.  Source
