Standing 8 feet high and weighing 300 pounds, the ostrich is easily the largest bird in the world. On African, grasslands it has adopted the habits of a grazing animal and groups roam about feeding in the company of zebras and gazelles. It is well adapted to this sort of habitat. Good eyesight and a long neck enable it to spot danger from a long way off. Powerful thighs and long legs can carry it at 40 miles an hour out of harm’s way. It is the only bird with two toes, another feature which enables it to run that much faster over the grassy plains.
