Size Length: 2 to 3 m (7 to 10 ft) Weight: 95 to 800 kg (209 to 1760 lb). Feeding Habits Brown bears are omnivores; they eat plants, berries, insects, rodents, fish, and carrion. They occasionally kill and eat larger animals. Offspring Female brown bears give birth to two or three cubs after a six- to nine-month gestation period. Cubs leave their mother after about two to four years. Life Span About 20 years. Did You Know Brown bears are not always brown--they may have black, red, or gray coats. There are many subspecies of brown bear, including the grizzly and the Kodiak. Coastal populations of brown bears that feed on fatty salmon may be three times larger than inland brown bear populations that subsist on plants, insects, and some meat. Unlike animals that hibernate, brown bears awaken easily during winter sleep and sometimes walk about. Microsoft ® Encarta ® 2009. © 1993-2008 Microsoft Corporation. All rights reserved.
