California grizzly bear
The California grizzly (Ursus arctos californicus) is an extinct population of the grizzly, the very large North American brown bear. "Grizzly" refers to the golden and grey tips of its hair. Genetically, North American grizzlies are closely related; in size and coloring, the California grizzly was much like the grizzly of the southern coast of Alaska. In California, it was particularly admired for its beauty, size, and strength. The grizzly became a symbol of the Bear Flag Republic, a moniker that was attached to the short-lived attempt by a band of American settlers to break away from Mexico. Later, this rebel flag became the basis for the state flag of California, and then California was known as the "Bear State."
