African Wild Ass

The African Wild Ass is a wild member of the horse family, Equidae. This species is believed to be the ancestor of the domestic donkey which is usually placed within the same species. They live in the deserts and other arid areas of northeastern Africa, in Eritrea, Ethiopia and Somalia; it formerly had a wider range north and west into Sudan, Egypt and Libya. About 570 individuals exist in the wild. The African Wild Ass is suited for life in the desert, capable of going on for up to three days without drinking water.

African wild asses are well suited to life in a desert or semidesert environment. They have tough digestive systems, which can break down desert vegetation and extract moisture from food efficiently. They can also go without water for a fairly long time. Their large ears give them an excellent sense of hearing and help in cooling. Because of the sparse vegetation in their environment wild asses live somewhat separated from each other (except for mothers and young), unlike the tightly grouped herds of wild horses. They have very loud voices, which can be heard for over 3 km, which helps them to keep in contact with other asses over the wide spaces of the desert.

The African Wild asses can run swiftly, almost as fast as a horse. However, unlike most hoofed mammals, their tendency is to not flee right away from a potentially dangerous situation, but to investigate first before deciding what to do. When they need to, they can defend themselves with kicks from both their front and hind legs. The African Wild Ass eats plant material, often eating thorn bushes and tougher plants that other animals ignore. They need to have water at least every three days, but they are able to survive on water that is dirty and brackish and can get a lot of their moisture from the plant material that they eat.

Sexual maturity of the female ass usually happens by the time she reaches two. Males can also reproduce at two, but it is so competitive that they usually are forced to wait until they are around four. Males are very territorial and will often hold a huge territory that is about 23 km, and they mark the edges of their territories with dung. Other males are allowed in, but they are kept away from the females as much as possible. Male donkeys will bray when the females are in season, and a dominant male of a territory has first right to breed with any female that comes around. Source

Asian Wild Ass

The Asian Wild Ass was once considered to be among the largest population of ungulates, along with horses, cows, camels, and deer. Herds of 1,000 or more Asian Wild Asses have often been observed in Central and West Asia. Like many other large grazing animals, the asian wild ass' range has contracted greatly under the pressures of hunting and habitat loss, and of the six subspecies, one is extinct and two are endangered.

Asian Wild Ass are a little larger than donkeys at about 290 kilograms  and 2.1 metres , and are a little more horse-like. They are short-legged compared to horses, and their coloring varies depending on the season. They are generally reddish-brown in color during the summer, becoming yellowish-brown in the winter months. They have a black stripe bordered in white that extends down the middle of the back. They are notoriously untameable.

The Asian Wild Ass lives in the grasslands and deserts of Central and West Asia.Most people associate a donkey with a slow moving animal, but the Asian Wild Ass is one of the fastest running asses in the horse family. They can run 70 kilometers or more per hour in short spurts. The kiang , a Tibetan relative, was previously considered to be a subspecies of the asian wild ass as E. hemionus kiang, but recent molecular studies indicate that it is a distinct species.

Today, the Asian Wild Ass is on the brink of extinction. This is partially due to the expansion of grazing land. Livestock animals have taken over their grassland and watering areas. But it is also because of an expansion of farmlands which has shrunk their habitat and forced them to separate. No longer is it possible to see herds of 1,000 asses. Conservation efforts have helped them recover their population in some areas, but as a whole, the Asian Wild Ass is still an endangered species. Source
