Ostrich
Ostrich is the largest bird on planet that doesn’t fly found in African savanna and desert lands, get their water mostly from the plants they eat. Ostriches are fleet, strong runners, can run up to 43 miles (70 kilometers) an hour. Their wings help to balance them and change direction while running. By the way ostriches do not bury their heads in the sand. But when trouble approach they lies low and lower their long neck to the ground for less visibility, when they do that their color blebs to the ground and from distance they appear buried their head in the sand.
