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.
Leopard
The leopard is a carnivore that prefers medium-sized prey with a body mass ranging from . Prey species in this weight range tend to occur in dense habitat and to form small herds. Species that prefer open areas and developed significant anti-predator strategies are less preferred. More than 100 prey species were recorded. Impala, Thomson's gazelle, duiker, steenbok, bushbuck, warthog, water chevrotain, blue wildebeest, sitatunga, Bates's pygmy antelope, aardvark, nyala, and kudu are frequently taken in Africa, and chital, muntjac, sambar, four-horned antelope, deer, Nilgiri tahr, gaur and wild boar in Asia. Primate prey species preyed upon include "Colobus", "Mangabey", "Cercopithecus", langur, and less frequently also gorilla and baboon. Small mammals preyed upon include black-backed jackal, Cape fox, African civet, genets, hares, porcupine, rock hyrax Prey as heavy as a giraffe is hunted if larger carnivores such as lions or tigers are absent. The largest prey killed by a leopard was reportedly a male eland weighing .
