An American breed of beef cattle, characterized by its long horns, which can span more than 8 ft (2.4 m) from tip to tip. It derives from cattle brought from the Iberian Peninsula to the Americas by Spanish conquistadores from the time of the Second Voyage of Christopher Columbus until about 1512. For hundreds of years the cattle lived a semi-feral existence on the rangelands; they have a higher tolerance of heat and drought than most European breeds.
