Of course there are not that many trees on the prairie, either. Cowbirds enjoy sitting on bison heads. Some people call bison buffalo. The French called them cows and oxen. This is partly right, but not the same.
Bison have close ties to people.
People shared the prairie with them, and they considered the bison their brothers. Well, I could not. Some cities are named after bison, and there are bisons for school mascots. Bison cannot be found on every prairie. The rarest bison is the white buffalo.
