Despite their massive size, bison are quick on their feet. When the need arises they can run at speeds up to 65 kilometers (40 miles) an hour.

They sport curved, sharp horns that may grow to be 60 centimeters (2 feet) long.

These large grazers feed on plains grasses, herbs, shrubs, and twigs. They regurgitate their food and chew it as cud before final digestion.

Known for roaming great distances, bison move continuously as they eat.

Females (cows) and adult males (bulls) generally live in small, separate bands and come together in very large herds during the summer mating season.

bison and indians

During the 19th century, settlers killed some 50 million bison for food, sport, and to deprive Native Americans of their most important natural asset.

Of the remaining American bison population, approximately 500,000 individuals are managed in human care as livestock by private commercial ventures, while conservation herds are comprised of around 30,000 individuals.
