Taxonomy

Subspecies

Three to four subspecies are recognized which were formerly split into two species:[1]

  • C. p. poliocephalus
  • C. p. ruwenzorii
  • C. p. guttifer
  • C. p. koesteri

Formerly split into two species (and currently split by Clements): Abyssinian (or Montane) Nightjar (poliocephalus) and Ruwenzori (or Montane) Nightjar (ruwenzorii, guttifer and koesteri). Forms a superspecies with Black-shouldered Nightjar and Fiery-necked Nightjar.

Habitat

Forest edges and interior of different types of montane woodland and forest, also in large wooded suburban garden and rocky terrain with juniper forest.
Occurs at 1000-3350 m.

Behaviour

Diet

Feeds on moths, beetles and grasshoppers.
Forages by hawking for prey above fields and pastures, in open woodlands and large suburban gardens. Has an extremely agile and rapid flight. Feeds also in insects attracted to artifical lights and fires.

Breeding

Poorly known. A monogamous and territorial species. Nests in small clearings at or near base of a tree or a bush. No nest built, the eggs are laid on bare ground or on leaf litter. Lays normally 2 eggs.

Movements

Probably sedentary in Africa. May move to lower altitudes in winter in Saudi Arabia.
