The African Ostriches are now very prominently in the public eye, not because of their relationship to the Dinornis and Aepyornis of the past, but by reason of the value of their plumes in enhancing the attractiveness of woman. And surely, no plume-bearing bird ever enlisted in a better cause, or on a more satisfactory basis; for to-day the plume crop is being grown and plucked and marketed with almost as much certainty as the annual crop of wool. In the United States, the most important plume-producing ostrich farms are situated in southern California and Arizona, where the industry is quite successful. So valuable are the adult birds that it is possible to purchase specimens imported from Africa for less money than would be necessary to procure them in the United States.

A full-grown male African Ostrich stands 8 feet in height, and weighs about 300 pounds. Its value on arrival in New York, before acclimatization and moulting into perfect plumage, is from $200 to $250. The female lays about 90 eggs in a year, each of which is equal to about 20 hen's eggs. The time of incubation is about 40 days. In captivity only about 60 per cent of the eggs hatch, and of those not more than one-half live to attain full maturity. The plumage of immature birds and adult females is gray, but that of the adult male is black on the body, and white on the wings and tail.
The South African Ostrich, (_Struthio australis_), differs from the species found in the north. The color of the naked skin of its neck and thighs, and the front scales on its metatarsus, is distinctly bluish, and dark. This is the species of the southern half of Africa, now so successfully farmed in Cape Colony for its feathers that the annual crop is said to yield about $5,000,000. And it is this species which is kept on the ostrich farms of California and Arizona.
The North African, or Sudan Ostrich, (_S. camelus_), is the species first and longest known. Its neck, thighs and front metatarsal scales are of a decided pink color. Originally the range of this species extended from north Africa well into southwestern Asia, embracing Arabia, Syria and Mesopotamia.
Generally speaking, the African Ostriches originally covered all the open, sandy plains of Africa; but they never inhabited the regions of dense forests. To-day their total inhabited range is small, and rapidly becoming more so. It is highly probable that within the life period of many persons now living, wild Ostriches will totally disappear from the earth.
