Hirola are selective grazers, depending on short grasses. Occasionaly they have been oberserved to consume forbs. Their selectivity creates a need to follow the progress of newly sprouting grasses on the savannah and grasslands. If grasses grow too long, or if the grasses are disturbed by other grazers, they will move to another area. Early evening and morning are the times of highest intensity feeding.
Hirola are able to survive lengthy periods without drinking by avoiding energetic activities and storing fats.
