Name
In American Western culture, the bison is commonly referred to as "buffalo"; however, this is a misnomer: though both bison and buffalo belong to the Bovidae family, the term "buffalo" properly applies only to the Asian water buffalo and African buffalo. The gaur, a large, thick-coated ox found in Asia, is also known as the "Indian bison", although it is in the genus Bos and thus not a true bison.
The plural of "bison" is normally also "bison", not "bisons".
Description
The American and European bison are the largest terrestrial mammals in North America and Europe. Bison are nomadic grazers and travel in herds, except for the non-dominant bulls, which travel alone or in small groups during most of the year. American bison are known for living in the Great Plains. Both species were hunted close to extinction during the 19th and 20th centuries but have since rebounded, although the European bison is still endangered.
Unlike the Asian water buffalo, bison have never been domesticated, although the American bison is kept on some farms.
Bison are born without their trademark hump and horns and live for approximately twenty years. They grow to maturity at two to three years, although males continue to grow until about their seventh year. Adult bulls express a high degree of dominance competitiveness during mating season. Male bison fight for females and these fights often result in injury or death. After the bison mate, the herd splits up into smaller herds. Calves are born nine months after mating. The mothers take care of and nurse their young for a year.
Male bison grow to as much as to 11.5 feet (3.5m) long, and 6.5 feet (2m) tall at the shoulder and can weigh up to 2200lbs (998 kg).
