Antelope jackrabbit
The antelope jackrabbit feeds on cacti, grasses, and other leafy vegetation. This species has been observed digging and eating soil in an attempt to intake minerals and other nutrients. They can be classified as folivores and graminivores.
Royal antelope
The royal antelope exhibits remarkable alertness, and consequently little is known about its behaviour. The animal will immediately seek cover if alarmed and flees as soon as the danger is very close. It can move swiftly, either by sprinting fast with the body low to the ground, or through strong leaps powered by the large, well-muscled hindlegs. It can cover in a single leap, and rise as high as above the ground.
It is typically nocturnal (active at night), though activity may also be observed during the day. It generally rests or ruminates during the day. Territories are marked with dung. The reduced size of the preorbital glands, which are used for scent-marking, could indicate that marking behaviour is not very prominent in this antelope.
