The bison is the largest land mammal in North America.

An adult male bison is called a "bull"; an adult female is called a "cow"; and a young bison is called a "calf".

The adult bison weighs between 800 and 2000 pounds. (An adult bull can weigh up to 2000 pounds and can stand 6.5 feet tall. An adult cow can weigh more than 1000 pounds and is only a little shorter than a bull.

Bison move an average of 2 miles per day to graze.

When necessary bison can run 35 miles per hour and keep that pace for half an hour.

Both male and female bison have horns. The average bison horn is 2 feet long, and the span between two bison horns can be more than 2 feet.

The calf is born without horns or hump. They start to grow when the calf is 2 months old.

People think that there were at least 30 to 60 million (30 000 000 to 60 000 000) bison in North America in the early 1700's. In the 1800's, Europeans hunted the bison nearly to extinction. Today there are about 65 000 bison in the United States
