The African ostrich is the world's tallest living bird; where does the second tallest, the emu, come from?
Common ostrich The ostrich or common ostrich ("Struthio camelus") is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus "Struthio", which is in the ratite family. In 2014, the Somali ostrich ("Struthio molybdophanes") was recognized as a distinct species.
Mullerornis Mullerornis is the smaller of the two genera of extinct elephant birds (Aepyornithidae) of Madagascar (the other is "Aepyornis"). Species include "Mullerornis agilis" Milne-Edwards and A. Grandidier, 1894, and "M. grandis" Lamberton, 1934. A bone possibly belonging to "Mullerornis" has been radiocarbon dated to about 1260 BP, suggesting that the animal was still extant at the end of the first millennium.
