Somali ostrich
The Somali ostrich (''Struthio molybdophanes'') is a large flightless bird native to the Horn of Africa. It was previously considered a subspecies of the common ostrich, but was identified as a distinct species in 2014.〔
==Taxonomy and systematics==
Molecular evidence indicates that the East African Rift has served as a geographic barrier to isolate the taxon from the nominate subspecies, the North African ostrich ''S. c. camelus'', while ecological and behavioural differences have kept it genetically distinct from the neighbouring Masai ostrich ''S. c. massaicus''. An examination of the mitochondrial DNA of ''Struthio'' taxa, including the extinct Arabian ostrich ''S. c. syriacus'', has found that the Somali ostrich is phylogenetically the most distinct, appearing to have diverged from their common ancestor some 3.6 to 4.1 million years ago.〔
