Grizzly Bear

(go back to The Animals)

The fiercest and most aggressive of all bears, the grizzly, also known as the brown bear, has no natural enemies or predators. The grizzly lives a solitary life except during breeding and cub rearing. The female gives birth to a litter of 1-3 cubs while hibernating in a den during the winter months. When the cubs emerge from the den in the spring, they will weigh about 20 pounds. The cubs remain with the mother for 2-4 years. The omnivorous grizzly eats both vegetation and animals, from grasses, roots, and berries to insects, fish, and various mammals. Grizzly bears live in a variety of habitats from dense forests to subalpine meadows and arctic tundra. Grizzlies are found in Canada, Alaska, Wyoming, Montana, Idaho, and Washington. In 1975 the grizzly bear was listed as a threatened species under the Endangered Species Act in the lower 48 states. In 2007 the Yellowstone population of grizzly bears was declared recovered and removed from the ‘Threatened’ species list. The biggest threat to grizzlies is human-caused mortality when they come into contact with humans through garbage, pet, and bird foods left out where the bears can get them. They are also often accidently killed by hunters who mistake them for black bears, which are legal to hunt. They are also impacted, of course, by habitat loss due to development, logging, and other human-related activities.
