French: Engoulevent du Ruwenzori German: Ruwenzorinachtschwalbe Spanish: Chotacabras del Ruwenzori
Other common names: Ruwenzori Nightjar

Taxonomy: Caprimulgus ruwenzorii Ogilvie-Grant, 1908, Mubuku Valley, Mt Ruwenzori.
Often considered conspecific with C. poliocephalus; these two form superspecies with C. nigriscapularis and C. pectoralis. Angolan population has been separated as race koesteri, and in tail pattern appears intermediate between nominate and guttifer; this isolated population has even been suggested to be a separate species. Race guttifer has occasionally been treated as a separate species. Both of these forms have alternatively been considered races of C. poliocephalus. Two subspecies currently recognized.

Subspecies and Distribution:

  • ruwenzorii Ogilvie-Grant, 1908 - SW Uganda to E Zaire; separate population in W Angola.
  • guttifer Grote, 1921 - SW Tanzania, N Malawi and NE Zambia; separate population in NE Tanzania.
