Habitat:
Occurs in tropical forests, typically ranging in lowland swamp forest and seasonally flooded forest, waterlogged habitats along streams and areas with poorly drained or permanently saturated soils. It also inhabits montane forests, subalpine vegetation zones, bamboo, and moorland on Mt Elgon, Mt Kenya and the Aberdares (Plumptre 2013). In the Ituri Forest, DR Congo, it occurred in both mixed and monodominant Gilbertiodendron forests but only along water courses in both types (Hart 2000).
Range:
The Black-fronted Duiker occurs widely in the Lower Guinea and Congo Basin Forests from the Niger Delta east to the Albertine Rift and south to northern Angola, and in montane forests in East Africa. The Nigerian population in the Niger Delta is probably disjunct from the nearest known population in Cameroon (East 1999, Plumptre 2013). In Uganda they are known on Mt Elgon, the Rwenzori mountains, Bwindi Impenetrable Forest, in Rwanda in Volcanoes NP and Nyungwe Forest Reserve, and in Kenya on Mt Kenya, the Aberdares and Mt Elgon (Plumptre 2013). Isolated populations of this species were recorded on Mounts Cameroon, Kupe and Manengube by Bowden (1986), but Grubb et al. (2003) were not convinced these records relate to Black-fronted Duiker.
C. n. rubidus is confined to the Ruwenzori Mountains at altitudes of 1,300-4,200 m, although it is thus far only recorded from the Ugandan side of the range (Kingdon 1982, Grubb and Groves 2001, Kingdon 2013).

Conservation:
The Black-fronted Duiker is present in a number of protected areas such as Lobeke (Cameroon), Dzanga-Sangha (Central African Republic), Lac Télé-Likouala and Nouabale-Ndoki (Congo-Brazzaville), Virunga, Ituri, Maiko, Kahuzi-Biega and Salonga (Congo-Kinshasa), Bwindi (Uganda), Volcanoes National Park (Rwanda) and Mount Kenya. Most of these key populations are stable.
Much of the Ugandan range of the Rwenzori Red Duiker is included within Rwenzori Mountains National Park. There is a need for further taxonomic work to determine whether this subspecies does indeed deserve recognition as a distinct species (as considered by Kingdon 2013).
