Sorry, no etymologies found.
These great birds, together with others, such as the epiornis and palapteryx, have disappeared, not through the ordinary course of nature, but by the hand of man.
One such reason is the way in which struthious birds are, or have been, distributed around the antarctic region: as the ostrich in Africa, the rhea in South America, the emeu in Australia, the apteryx, dinornis, &c. in New Zealand, the epiornis in Madagascar.
