The American bison makes its home in the grasslands and prairies of North America. This mammal is up to about 1.8 meters tall at the shoulder. Life in such a place is hard, but the American bison's body and habits are a good match for it.
One reason the American bison survives is a thick, shaggy winter coat, which keeps it warm in freezing prairie winds. It also has a huge head and strong neck, which sweep snow aside to reach the grass underneath.
The American bison is a herbivore, which means it is an animal that eats only plants. Its food includes grasses and sedges. To find food, it lives in herds that roam the prairie to find fresh grass.
Young American bisons are called calves. Calves are born a reddish color and darken as they grow. The American bison is the national mammal of the United States.
