What is the biggest bird?

Native to Africa, the ostrich is the biggest bird on the planet. Although it cannot fly, the ostrich is an excellent runner and can reach a top speed of 43 miles per hour.

In addition to being the biggest and fastest running bird on the planet, the ostrich lays the largest egg of any bird.

A common myth is that the ostrich buries its head in the sand when afraid. Instead, the ostrich often flattens its neck against the ground to reduce its visibility to potential predators. If cornered, the ostrich uses its powerful legs and sharp claws for defense.
