The Grizzly Bear, sometimes called the Silvertip Bear, is a powerful brownish-yellow bear that lives in the uplands of western North America. It has traditionally been treated as a subspecies, Ursus arctos horribilis, of the brown bear living in North America.
Large, powerful and sometimes deadly, the grizzly bear has fascinated man for centuries. Yet despite its formidable size and fearsome claws and teeth, it's shaggy appearance and appealing features make it firm favourite with many people the world over.
Grizzly or Brown bears have the widest distribution of any bear species and occupy a wide range of habitats, from dense forests, to sub alpine meadows and arctic tundra.
They have a life span of 25-30 years and are omnivores eating everything humans can eat and more.
Grizzly Bears are mostly nocturnal and are not really true hibernators; they sleep in dens during winters and can be easily awakened.
The grizzly got its name because of its grizzled, silver tipped coat, which may be brown, black or blonde, or a combination of the 3.
Your chances of seeing one in the wild
Pretty good if you go to the right places at the right time of the year (such as west coast Canada and Alaska during the Salmon run in the Fall/Autumn).
However, the Grizzly Bear is classed as threatened in the United States and is vulnerable in Canada. It has no natural enemies, but is endangered due to poaching and loss of habitat. Another reason for its dwindling population is that grizzlies produce only 1 or 2 cubs per pregnancy.
