The ostrich is the bird that can run the fastest. Ostriches can sustain speeds of 30 miles per hour, and sprint up to 40 miles per hour or more.
Standing about 9 feet tall and weighing hundreds of pounds, the ostrich is the fastest bird to run on land. Native to East and South Africa, the ostrich is able to run at about 30 miles per hour for up to 10 miles. When needed, it can sprint at even faster speeds of at least 40 miles per hour. Unfortunately, the bird weighs far too much and has too small a wing to fly.
