Ostrich do not have teeth. They shift the food to their http://www.answers.com/topic/crop (a holding pocket in her esophagus), pick up their head to about ankle height, and move on. The head pecks again, this time getting small bits of gravel. Now amongst brown grass, it finds seeds. Its head moves here and there pecking up the bounty like a strange long-legged, long-necked, precisely-pecking chicken. It raises its head to its full 8-foot (2.4 m) height, peers around for trouble, and swallows. The ball of seeds, half-devoured lizard, and gravel emerges from the crop and slides slowly down its neck - stretching the neck skin as it goes - finally into ist tough muscular stomach, called a gizzard. The bits of gravel and sand that it swallowed earlier act as teeth in the gizzard and grind the hard food into manageable bits for its intestines to digest. Its gizzard content may be 45% sand and stones. All birds have gizzards and "chew" their food this way. Its 45-foot (14-m) long intestine (twice the length of a human's) is long enough to absorb practically every scrap of nutrients in the food.
