Ralphie the Buffalo is the name of the live mascot of the University of Colorado Buffaloes. The current Ralphie – nicknamed Ember – is the sixth bison to fill the role since 1967. Ralphie is best known for running a horseshoe pattern around Folsom Field prior to each half of home football games. She begins each run as the public address announcer exclaims Here comes Ralphie! and typically leads the football team as they enter the playing field. She has frequently been named one of the best mascots in sports.[1]

While commonly referred to as a buffalo, Ralphie is actually an American bison.[2] Due to their smaller size, reduced strength, and less-aggressive temperament, female bison have always been chosen as Ralphie as opposed to males.[3] She can reach speeds of 25 miles per hour, and it traditionally takes five handlers to guide her around the field. The team of approximately 15 Ralphie Handlers are student-athletes that earn varsity letters for their efforts. They spend more than 20 hours per week training, practicing, and caring for Ralphie, while rotating the privilege of running with her at the games.[4]
