Both the Greater Roadrunner (famous from the looney tunes cartons) and Ostrich are fast birds on land. The Greater Roadrunner can run at speeds of up to 20 miles per hour (32 km/h) which is fast for its size (56 centimeters 22 in long). The Ostrich on the other hand can run at speeds of up to 45 miles per hour (72 km/h) and is 1.8 to 2.75 meters (6 to 9 ft) above the ground which is considerably bigger than the Roadrunner. The Ostrich is also the fastest running bird.
