The ostrich’s habit of eating stones originally caused much consternation before its purpose was realized. The size of each section depends upon a bird’s diet. The ostrich, emu, and rhea have well-developed gizzards because of the more fibrous nature of their food, and the grit they eat goes directly there through the crop. It is not passed out with the digested food, so the stomach can be quite empty of food while the gizzard still retains its grit. However, too much grit can cause problems even for an ostrich.
