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.
Different animals can survive without water for different periods of time. For example: A fish can not go very long at all without water but a camel can go a very long time without water. Humans can go without water for about 98 hours but after that they are almost dead.
they can last for long time without water because they have long tounges and 'dudes'
100 days without food or water
