OSTRICH, common name for a large, flightless bird, Struthio camelus, the only member of the family Struthionidae and the order Struthioniformes. It is now found only in Africa, but was formerly in the Middle East, where it is probably extinct. Ostriches are the largest and strongest of living birds, attaining a height from crown to foot of about 2.4 m (about 8 ft) and a weight of up to 136 kg (300 lb). They have long necks and small heads, with large eyes and short, broad beaks. They spread their small wings when running and have long, powerful legs that are used for defense. The feet have only two toes. Male ostriches are black, with white wings and tail. The white feathers of the male, which are large and soft, are the ostrich plumes of commercial value. The female is a dull grayish brown. |
