Antelope
or Pronghorn

"Beautiful and keenly made," wrote Clark as he admired the antelope.  He was also very impressed with its speed, which was "rather like the rapid flight of birds."    The pronghorn is the fastest animal in America.  It can run as fast as 60 miles an hour. 

Lewis and Clark didn't get to eat much antelope steak. Because it lives on open prairies, the antelope can detect enemies and race away before they get close. 

Pronghorns stand about three feet high at the shoulder and weigh 80-100 pounds.  They have large  ears, slender legs, and a short tail.  The pronghorn family is made up of bucks, does, and fawns.

 

These animals roam the prairies from Canada to Mexico, and they can be seen from the highway in parts of southern Idaho.

Pronghorns eat leaves of plants and other shrubs.  Their natural enemies include wolves, coyotes, and eagles.

Every year, pronghorns shed their horns   and grow new ones.  All bucks have horns, and some (but not all) of the does have horns.
