Buffalo is also called the American Bison. It lives in North America. Bison are large animals, they have a brown coat, a massive hump on their back and two horns for defense and fighting. They eat plants, grasses and sedges. Bison can be dangerous, they are wild and unpredictable. They attack when they are provoked. A buffalo can run very fast, and he can also jump very high! In the 1800s thousands of bison were killed for their coat. Today they are still endangered because their habitat is destroyed and gets smaller and smaller. In Wyoming, USA, wild buffaloes are preserved in a place called Yellowstone National Park.
The plural of buffalo can be buffalo or buffaloes and the plural of bison is also bison. I made some changes.
