This is a profile of an American bison, also called an American buffalo. A bull’s weight ranges from 700 to over 2,000 pounds. In the 15th century, approximately 60 million American bison roamed the plains. After extensive hunting, those numbers declined to less than a thousand and almost became extinct. Today, bison herds can be found in several national parks, private ranches and public parks such as the Wildlife Safari in Winston, Oregon.
