Ostrich

Cool Fact:

The Ostrich is the largest and heaviest living bird, and the only one with just two toes.  The inner toe is thick and strong, and it is on this that the bird runs.  The fastest-running bird, the Ostrich can maintain speeds of up to 30 mph (50 kph) for up to 30 minutes.  In short sprints it can reach 45 mph (70 kph), with strides of 11 feet (3.5 m).
