Royal antelope
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
Common eland
Common elands are herbivores that browse during drier winter months but have also adapted to grazing during the rainy season when grasses are more common. They require a high-protein diet of succulent leaves from flowering plants but will consume lower quality plant material if available including forbs, trees, shrubs, grasses, seeds and tubers. The eland can conserve water by increasing its body temperature. Grasses the eland eats include "Setaria" and "Themeda" and fruits from "Securinega" and "Strychnos". Large antelope can survive on lower quality food in times of little rain. Elands feed during the night in hot weather and sleep for long periods during the day.
