If you saw a big blackish-brownish thing that growls and struts back and forth and seems to be searching for something, it may be a black bear. Compared to the brown bear and the polar bear it is the smallest. They live in most of North America up to Alaska and even as far south as Mexico. They live in mountains and forests. Male bears weigh 375 pounds.
Females weigh slighty less than the males.
The biggest black bear ever weighed was over 800 pounds. They come in different colors also. Not all black bears are black, most are black with a brownish muzzle. But some are almost white. Cinnamon is common in the United States.
