I took this photo October 22, 2011. There was a small herd near I-70 west of Denver, Colorado. I’m guessing this is a bison, though I think some buffalo have been imported, so I’m not positive.
THE DIFFERENCE BETWEEN BISON & BUFFALO
Source for the following information: http://www.lifeslittlemysteries.com
Early American settlers called bison “bufello” due to the similar appearance between the two animals, and the name “buffalo” stuck for the American variety. But it’s wrong.
The American bison (Bison bison) lives only in North America, while the two main buffalo species reside in Africa and Asia. A small population of bison relatives called the European bison (Bison bonasus) lives in isolated parts of Poland.
Like buffalo, bison belong to the Bovidae family, which includes more than 100 species of hoofed mammals, called ungulates—buffalo, bison, antelopes, gazelles, cattle, sheep and goats. Two main buffalo species exist: African cape buffalo and Asian water buffalo.
If you were to stand eye-to-eye with a buffalo species and a bison you’d notice stark physical differences. Unlike any buffalo species, the American bison has a large shoulder hump and a massive head, which gives this symbol of the West its burly appearance.
