Bison are born in April and May and reach adulthood at the age of 8. Cows care for their young until they're about three. Bison can live in places where it is very cruel. Much of the land bison live on today is the same as when Lewis and Clark came. You can tell if a bison is male or female by its horns.
Bulls have straight out and up horns while cows have a barely visible hook on the end.
Today most bison live in refuges. Each year the Bison Range holds a round-up. Surplus animals are then sold. The buffalo pens are very interesting, especially if you have never been close to buffalo. The pens have to be strong to be able to hold all the buffalo ramming into them.
