Guide to the Mammals of Colorado - Black Bear Page Colorado has been home to bears since their earliest ancestors evolved in North America. These large, powerful animals play an important role in the ecosystem. For many people, seeing a bear is rare and the highlight of an outdoor experience. Learning about bears and being aware of their habits will help you fully appreciate these unique animals and the habitat in which they live.
Black bears are the most common and generally the smallest of North American bears.
Today, only the black bear is known to exist in Colorado. Although we do not know exactly how many black bears live in Colorado, population estimates range from 8,000 to 12,000 bears. A black bear may live 20 years in the wild, although very few do, and up to 25-30 years in captivity. Black bears are very agile, can run in bursts up to 35 mph and can run up or down hills quickly and easily. Their short, curved claws help them to climb trees.
