Struthio molybdophanes (prev. S. camelus molyb.)
Prior to 2014 there were 4 subspecies of Ostrich
Struthio camelus, all from Africa.
The Arabian Ostrich, S. c. syriacus, became extinct in 1966.
In 2014, the Somali Ostrich (above), also called the Blue-necked, was reclassified as a full species,
S. molybdophanes. The male's grey neck and grey legs become more blue in the breeding season.
The female is darker brown than the other species.
The nominal subspecies of "common" Ostrich (above),
Struthio camelus camelus, comes from North Africa, mainly south of the Sahara, and is called the Red-necked,
Northern or North African Ostrich.
As its name indicates, the male has pink-red neck and legs, becoming very red for adult males in the breeding season (above).
The Southern Ostrich,
S. c australis, also called the South African and, misleadingly, the Black-necked,
is the most common and native to southern Africa. It has a greyish neck and grey or pinky-grey legs. As with all Ostriches,
the male plumage is black with white/off-white and the female (above right) is brown or grey-brown.

The Masai Ostrich,
S. c. massaicus, also called the Pink-necked, comes from parts of East Africa (Kenya/Tanzania).
It has a pinky-grey neck and pink legs.
