(von Heuglin & Fitzinger, 1866)[2]

The Nubian wild ass (Equus africanus africanus) is a subspecies of the African wild ass, and probably the ancestor of domestic donkeys,.[3] The ass was domesticated about 6,000 years ago, probably in Egypt or Mesopotamia.[citation needed]

The Nubian wild ass is most likely extinct in the wild since the 1950s.[citation needed] However, the IUCN Red List [1] still mentions it as critically endangered. It is closely related to the Somali wild ass,[citation needed] which is also on the brink of extinction in the wild.

In 2014, blood samples from four individual wild donkeys from the island of Bonaire were sent to the Department of Veterinary Integrative Biosciences at Texas A&M University to have Mitochondrial DNA sequencing done to determine the identity of this species. The tests results were conclusive that the donkeys "had perfect match to haplotypes of historic Nubian Wild Ass" and that "this result indicates that the Bonaire donkeys are direct descendants of the Nubian." Full 5-page report here: Link label, Link label, Link label, Link label, Link label. Wildlife Ecologist and President of the Andean Tapir Fund, Craig C. Downer has urged in a letter dated March 6, 2014, to the Honorable Governor of Bonaire that the government of Bonaire protect the donkeys as a Critically Endangered (CR) subspecies. To date, no action has been taken by the government. Statements have been made by local residents that the male donkeys are currently being captured and castrated and local organizations are being formed to save the species.

The Nubian wild ass is known for its stamina.[citation needed] It has a slender body and a stripe across the shoulder.[citation needed] Its head is rather large, with two long slender ears.[citation needed] The shoulder height of the Nubian wild ass is about 120 centimeters.[citation needed] Skin color varies from light brown to gray.[citation needed]


Nubian wild asses used to live in the northeast of Africa,[citation needed] ranging from mountains and rocky areas to semideserts and grasslands.[citation needed] Feeding occurs during the night and early morning.[citation needed] The diet includes grasses and types of forbs.[citation needed] During the heat of day, the Nubian wild ass takes refuge in the shade.[citation needed]


Males tend to live alone or in small groups.[citation needed] Females and young animals live in herds.[citation needed] There is no strict hierarchy in the herd, and when fights erupt, the animals kick and bite each other.[citation needed]


After almost a year of gestation, the female typically gives birth to one foal.[citation needed] The mother and foal separate themselves from the herd until the foal is able to recognize its mother.[citation needed]
