Ostriches

Ostriches have big eyes if you didn’t know their eye is as big as their brain. I'm not saying that they're dumb I'm just saying that because it’s a fact. Ostriches are the larges bird in the world. When they are scared they stick their heads into a bush or into anything they can find its just the natural thing that they do. They can run at 45 miles an hour which is twice as fast as a human can. They may be birds but they can’t fly. How humans have to stop when they're running because they get tired an ostrich can run 45 miles an hour really fast for up to half an hour. When they sleep it may look like they're burrying their heads under ground but really they're just sleeping with their neck stretched out.
