Bush Duiker (Sylvicapra grimmia) lives in open savanna across Sub-Saharan Africa. It feeds on leaves and fruits. Its conservation status is Least Concern.
Fascinating facts about the Bush Duiker
- The bush duiker is the only species placed in the genus Sylvicapra, giving it a singular taxonomic status. Its scientific name, Sylvicapra grimmia, is also linked to the common name gray duiker. It occupies almost the entire sub-Saharan region, avoiding only the Horn of Africa and the central-west rainforests. The animal prefers habitats with enough vegetation cover, such as savannahs, hilly areas and the edges of human settlements, where it can hide effectively.
- Only male bush duikers develop horns, which can grow up to 11 cm long, while females never grow any, illustrating a clear sexual dimorphism in horn presence. Males also mark their territories by smearing secretions from pre-orbital glands onto rocks and branches. Females, in contrast, tend to seek deeper cover when resting. This combination of visual and scent cues helps males defend elevated resting sites where they can watch over their range.
- Bush duikers supplement their plant-based diet with insects, frogs, small birds, mammals and even carrion, making them highly opportunistic feeders. They also browse leaves, flowers, fruits and tubers, and can exploit food from recently burnt habitats that many other herbivores avoid. Because they obtain much of their water from the moisture in fruits, especially in the rainy season, they can go for long periods without drinking.
- Bush duikers are able to eat food from recently burnt areas, a resource many herbivores avoid, because they can consume a wide range of items. This dietary flexibility lets them persist on farmland more successfully than larger antelopes that need a narrower menu.
- Both captive and wild bush duikers can harbour several internal parasites, showing they are vulnerable to infection. Among these parasites is the blood-fluke Trypanosoma brucei, which is the cause of sleeping sickness in people. Their role as hosts means they can carry the disease without showing obvious signs, linking them to human health concerns in regions where the parasite occurs.

About the Bush Duiker
In the dappled undergrowth of Africa's woodlands, the bush duiker weaves a secret path, its large, dark eyes watchful and alert as it navigates the shadows. With a quiet elegance, it moves through the dense thicket, its slender legs barely disturbing the leaf litter as it searches for the tender shoots and fruits that sustain it. As it pauses to sniff the air, its oversized ears twitching with every subtle sound, the bush duiker embodies the very essence of a life lived in harmony with the forest's hidden rhythms.
