Although there were once millions of bison roaming the North America grasslands, wholesale slaughter by the early European settlers brought them almost to extinction by the beginning of the 12th century. The bison are around nine and half feet tall. Male are usually brownish black.
Females are usually reddish brown and are little smaller than the males.
