Animal Summary

Zoo owned bison, Thelma and Louise, came to the zoo in 2011.  They were both born in April  of 2010 at the DaVals White Buffalo Farm in Janesville, Wisconsin.  Both girls came from a male who has bloodlines that run back to Canadian bison and their mothers both have woods bison blood in them.


  • Bison use the thick mat of course hair on their heads to sweep away deep snow and uncover vegetation for grazing.
  • A bison and buffalo are two different animals.  The bison is only found in North America whereas the buffalo, namely the water buffalo, is found in Africa and Asia.
  • Although a bison is very large, reaching almost 6 feet at the shoulders and weighing up to one ton, they can reach speeds up to 40 miles per hour for short distances.

Bison once numbered tens of millions but due to the unregulated shooting in the 19th Century their numbers plummeted to less than 2,000.  Today their numbers only reach 500,000.  The majority are kept on ranches and raised as livestock with only about 20,000 being truly wild.


Bison depend on large expanses of connected habitat that are becoming rare due to man-made barriers such as ranchland, roadways, and suburban sprawl.
