The Struthio camelus or Ostrich is a species of flightless bird native to certain large areas of Africa.

The Struthionidae or Ostrich is the largest living species of bird and largest living dinosaur. It lays the largest eggs of any living bird.
Males stand 6 ft 11 in to 9 ft in. tall and weigh 220–290 lb., whereas females are about 5 ft 9 in to 6 ft 3 in. tall and weigh 200–260 lb.

The long neck and legs keep their head up to 9 ft 2 in. above the ground, and their eyes are said to be the largest of any land vertebrate helping them to see predators at a great distance. The eyes are shaded from sunlight from above.

The Struthio camelus or Ostrich head and bill are relatively small for the birds’ huge size, with the bill measuring 12 4 3⁄4 to 5 3⁄4 in.

Their skin varies in color depending on the subspecies, with some having light or dark gray skin and others having pinkish or even reddish skin.
The strong legs of the common ostrich are unfeathered and show bare skin, with the tarsus (the lowest upright part of the leg) being covered in scales: red in the male, black in the female.

The tarsus of the common ostrich is the largest of any living bird, measuring 15 1⁄2 to 21 in. in length. The bird is didactyl, having just two toes on each foot (most birds have four), with the nail on the larger, inner toe resembling a hoof. The outer toe has no nail.

The reduced number of toes is an adaptation that appears to aid in running, useful for getting away from predators. Common ostriches can run at a speed over 40 mph and can cover 10 to 15 ft. in a single stride.

The Struthionidae or Ostrich feathers lack the tiny hooks that lock together the smooth external feathers of flying birds, and so are soft and fluffy and serve as insulation.

Common ostriches can tolerate a wide range of temperatures. In much of their habitat, temperatures vary as much as 40 °C (70 °F) between night and day.
