Asian wild asses are the most horse-like of the wild ass species. Living on the flat, arid terrain of Syria, Iran and northern India, these beautiful russet-coated creatures are mostly solitary, but always found within 30km of water. Males defend large territories, mating with the females who wander through them. Encounters between the sexes are infrequent, since the sparse habitat doesn't support dense populations. The Mongolian wild ass is the most abundant sub-species.
Onager The onager (Equus hemionus) is a large member of the genus Equus of the family Equidae (horse family) native to the deserts of Syria, Iran, Pakistan, India, Israel and Tibet. It is also known as the Asiatic wild ass, Asian wild ass or wild Asian ass (in which case the term "onager" is reserved for the E. h. onager subspecies, more specifically known as the Persian onager).
