Are they bison or are they buffalo?

If you’ve ever cheered for CU Boulder, you’ve probably seen Ralphie, the spirited live mascot that charges across the field at football games.

Or perhaps you’ve driven along I-70 and seen a herd of these large, powerful shaggy creatures. But here’s the burning question—are these creatures bison or buffalo? 

Well, technically, they’re bison.

Bison and buffalo often get mixed up, but the difference is real!

Bison are native to North America and have the big hump and shaggy fur you see on Ralphie. Buffalo, on the other hand, are found in places like Africa and Asia and have larger, more rounded horns.

That said, socially the terms are used interchangeably. In fact, the nickname “buffalo” has stuck for CU Boulder’s mascot and in sports and local culture. 

Buffalo is also the name of choice for many indigenous people. So while scientists might say Ralphie is a bison, to many others, Ralphie is a beloved “buffalo” in spirit. 

So, whether you’re rooting for Ralphie the bison or the buffalo, you’re showing love for an animal that embodies the pride and spirit of the American west. 

Now, Environment Colorado is working to bring wild bison back to Colorado where they once roamed freely.
