Quick Summary

The American bison (Bison bison) is a large North American mammal known for its shaggy brown fur, distinctive hump, and short, sharp horns. Often mistakenly called buffalo, bison are native to North America, while true buffalo are found in Africa and Asia.123

Bison are the largest land mammals in North America, with males weighing up to 2,000 pounds (907 kg) and standing 6 to 6.5 feet (1.8 to 2 meters) tall at the shoulder. They have a broad, heavy head carried low, 14 ribs (compared to cattle's 13), and a thick beard.12

Historically, vast herds roamed the continent, providing sustenance for Native Americans. However, extensive hunting in the 19th century drastically reduced their numbers, bringing them to the brink of extinction. Conservation efforts have since helped populations recover, though concerns remain about genetic diversity.2
