Distribution and habitat

Occurs from Cameroon to Sudan, south through the DRC, Tanzania, Zambia and Angola to southern Africa. Within southern Africa it is locally common in the Caprivi Strip (Namibia), northern Botswana, Zimbabwe and central Mozambique, while scarce in north-eastern South Africa. It generally prefers mature broad-leaved woodland with plenty of leaf litter, especially if it has a substratum of sand, stone or burnt ground. 

Distribution of Pennant-winged nightjar in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.  

Predators and parasites

Movements and migrations

Intra-African breeding migrant, breeding in southern Africa and adjacent countries in the period from September-February, after which it heads north to its equatorial non-breeding grounds.

Food 

Mainly eats insects, doing most of its foraging over broad clearings at dusk and just before daybreak, catching prey aerially. The following food items have been recorded in its diet:

Breeding

  • Usually a polygynous solitary nester, with the male performing a spectacular display in which it flies around to display its long pennants, occasionally perching to give out a call. Strangely, a group of hundreds was once recorded in Zimbabwe mass-mating along a 25 km stretch of gravel road.
  • The nest is an unlined scrap in the soil, usually shaded by a tall tree.

  • Egg-laying season is from September-January, peaking from October-November.
  • It lays 1-2 eggs, which are incubated solely by the female for about 15-18 days; the eggs are readily deserted if the incubating female is disturbed.
  • Little is known about the development and care of the chicks.

Threats

Not threatened.
