Study the courtship practices of these flightless ratites and watch a mother ostrich care for its young
The long legs of the ostrich (Struthio camelus) are well-adapted to running, and the ostrich is the only two-toed bird. It is mainly a vegetarian grazer and is capable of swallowing a considerable volume in one gulp—note the bulge that moves down the ostrich's throat. Male and female ostriches each perform courtship displays, but the male is much more animated, gyrating and wildly waving his head. The female is more subdued, showing that she is ready to mate by spreading her wings and holding them close to the ground.
