The Asian wild ass, also called the onager, is endangered because of overhunting, loss of habitat, and competition with livestock for grazing land.

Today it lives in small groups led by a male or a mature female, but at one time herds of fifty to one hundred individuals were sighted following rainy periods.


Asian wild asses eat mostly grasses and will travel long distances to winter feeding grounds or to seek out a watering hole that will get them through a dry summer.

They can run faster than any other horse or ass, reaching and sustaining speeds of up to about forty-four miles (70 km) per hour.

There are four subspecies, each associated with a particular area. A fifth subspecies, which once ranged from Palestine to Iraq, is now extinct.
