"The Persian onager (Equus hemionus onager) is a subspecies of onager (Asiatic wild ass) native to Iran.
It is "critically endangered" and "extremely rare". Sometimes the term "onager" is reserved specifically for this subspecies. Information on the basic biology of the subspecies and how it differs from others is lacking, which hampers conservation efforts."

This was taken in the Shuamari Wildlife reserve were it was introduced after the Syrian Ass got extinct in 1927.
