The Cardinal Bird is the mascot of the University of Louisville. The Cardinal was chosen as the mascot after 1913, selected because the northern cardinal is the state bird of Kentucky. The school colors of black and red were adopted later. The Cardinal Bird is nicknamed "Louie". This is an homage to the name of both its school and city, as they are sometimes pronounced as "Louie-ville." Others choose to abbreviate his name, nicknaming him "C.B." His costume weighs over 50 pounds.
