The American bison (Bison bison) is a species of bison native to North America. Sometimes colloquially referred to as buffalo (a distinct species of bovine), it is one of two extant species of bison, alongside the European bison. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. Through multiple reintroductions, American bison now freely roam wild in several regions in the United States, Canada, and Mexico, with them, also being introduced to Yakutia in Russia.
Appearance
The color of the American bison fur varies in the front and back of its body and is different shades of brown. Bison is hunchbacked and it has a long beard on its chin. The forehead is wide and narrow while the neck is short. Hind legs are smaller than front legs, making up a scarp from humpback to tail. Length of hair differs in front and rear, especially in males: front hair is significantly longer than rear hair. Horns of bison are black, bent inward withal upward, and pointed.
Distribution

Geography
- Continents : North America
- Countries : Canada, United States
- Regions : Alberta, Ontario, Manitoba
In the past, a huge number of bison thundered North America from Mexico to Alaska. Then, mass killings of these impressive animals led to their total extermination from the main area of their habitat. However, bison survived and currently they live primarily in Canada and the western part of the USA, usually in protected areas and national parks.
Habits and Lifestyle
American bison is diurnal, being active all day long. They are usually relatively passive during the day, becoming particularly active at dusk and dawn. They spend a lot of time cleaning the fur or grooming: they rub their head, sides, and necks against trunks of trees. Bison are able to be constantly on the move, passing long distances as long as there is food. Cows, female bison, are leaders of family groups while males stay separate, creating small groups or living solitarily. As the mating season comes, males join female groups. Bison like rolling, weltering, and rubbing against the ground. Wallows are recesses – dust bowls with no vegetation, having circular form, formed as a result of bison’s wallowing on the ground.
