Forest duiker in Swahili: nsya (Cephalophus spp.)
Duikers are small to diminutive antelope with slightly hunched backs and a preference for forest undergrowth, where they are less often seen than they are heard crashing through the undergrowth. The red duiker (C. natalensis) is the most likely of Africa’s 12–20 ‘forest duikers’ to be seen by tourists. It is deep chestnut in colour with a white tail and, in the case of the East African race C. n. harveyi (sometimes considered to be a separate species), a black face. The blue duiker (C. monticola) is easily told apart from the red duiker by its greyer colouring and much smaller size. The all-but-endemic Abbott’s duiker (C. spadix) is relatively large duiker, as tall as a klipspringer, and is restricted to a handful of montane forest in Tanzania, including those on Kilimanjaro and the Usambara, Udzungwa and Poroto mountains. The endangered Ader’s duiker (C. adersi) is thought to be restricted to forested habitats on Zanzibar Island, where as few as 1,000 animals may survive, most of them in the Jozani Forest.
