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."
Antelope squirrel
Ground Squirrels are important disperses of seeds in the dry, shrubby deserts they live in. They participate in a behavior known as caching where seeds, fruits and vegetation are stored in burrows or hidden spots for consumption at a later time. The ground squirrels are omnivores and will feed on arthropods, insects, and carrion when these food sources are available. Their diets often rotate between green vegetation, fruits and seeds based on availability and season. All Antelope Squirrels carry their food in their cheek pouches for transport.
