Though sometimes called a buffalo, the American bison is not related to the water buffalo or the African buffalo, which are the only true buffaloes in the world. The American bison is more closely related to cows and goats.
Male bison are slightly larger than females. But both the male and female bison have a sizeable head with small curved horns and a scraggly beard.
Bison are herbivores, feeding on the grasses of the prairie land all year round. They will generally rest during the day and graze in the mornings and evenings. Bison also need to find water every day.
Although bison have few natural predators because of their size, wolves, mountain lions and bears do attack the very young or very old bison. In some areas, people legally hunt bison or raise them for their meat and hides. There are, however, some protected herds that reside in national parks and reserves.
During the mating season (June to September), male bison will use their large heads to butt each other in attempts to gain the attention of females. In April or May of the following year, the female gives birth to a single calf.
Calves are nursed for up to 8 months and are fully independent by 1 year of age. Male bison do not participate in the upbringing of the calves.
The American bison was once the symbol of the Great Plains. Vast herds roamed from Canada to Mexico providing food, clothing, and tools to the native people. From a population that numbered in the millions, American bison dwindled to near extinction, driven there by American settlers.
Although an ongoing conservation program has resulted in modest increases in their population, the American bison is currently classified as near threatened by IUCN’s Red List.
