The male bird is of a jet black glossy color, with the single exception of the white feathers, which are objects of trade.

Nothing can be finer than the adaptation of those flossy feathers for the climate of the Kalahari, where these birds abound; for they afford a perfect shade to the body, with free ventilation beneath them.

The hen ostrich is of a dark brownish-gray color, and so are the half-grown cocks.
The organs of vision in this bird are placed so high that he can detect an enemy at a great distance, but the lion sometimes kills him.

The flesh is white and coarse, though, when in good condition, it resembles in some degree that of a tough turkey.

It seeks safety in flight; but when pursued by dogs it may be seen to turn upon them and inflict a kick, which is vigorously applied, and sometimes breaks the dog's back..
