Asian wild ass  (Equus hemionus)

This species eats grasses when available, but will browse on shrubs and trees at other times or in drier habitats (3). They have been seen feeding on seed pods and breaking up woody vegetation with their hooves to get at more succulent herbs growing at the base of the woody plants. In Mongolia they eat snow in winter as a water substitute, and they often dig holes in dry riverbeds to obtain water (4).

Breeding is seasonal, the gestation period in this species is 11 months, and most births occur from April to September. Females with young tend to form groups of up to five females. Males have been observed holding harems of females, but in other studies they defend territories that attract females. It is likely that differences in behaviour and social structure are the result of changes in climate, vegetation cover and hunting. (4).
