An American bison bull

American bison

American bison are the largest land mammals in North America. Massive herds once roamed far and wide across the grasslands and savannas of north America, from Alaska all the way down to Mexico. Nowadays, herds are largely restricted to reserves and parks. Despite the bison's poor eyesight, danger is still detected well in advance, because they have excellent senses of hearing and smell. However, the formidable size and defences of the adults also keep them very safe. Bison calves are capable of walking and even running hours after being born.
