The free animal screensaver, Grizzly Bear, contains 14 high quality images of Grizzly Bears. 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. Grizzly bears reach weights of 180 680 kilograms (400 1,500 pounds) and stand a height of 2.44 m (8 feet) tall when standing on its hind legs; the male is on average 1.8 times as heavy as the female, an example of sexual dimorphism. This dimorphism suggests that size is an important factor in the male’s ability to successfully compete for and attract breeding opportunities. Their coloring ranges widely across geographic areas, from blond to deep brown or black. These differences, once attributed to subspeciation, are now thought to be primarily due to the different environments these bears inhabit, particularly with regard to diet and temperature. - wiki Grizzly Bear is a free screensaver created by RateMyScreensaver.com.
