Yellow-backed duiker
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
African leopard
The leopard has an exceptional ability to adapt to changes in prey availability, and has a very broad diet. Small prey are taken where large ungulates are less common. The known prey of leopards ranges from dung beetles to adult elands, which can reach . In sub-Saharan Africa, at least 92 prey species have been documented in leopard scat including rodents, birds, small and large antelopes, hyraxes and hares, and arthropods. They generally focus their hunting activity on locally abundant medium-sized ungulates in the range, while opportunistically taking other prey. Average intervals between ungulate kills range from seven to 12–13 days.
