Field Identification

21–23 cm; male 54–64 g, female 50–69 g. Sexes similar. Slight colour variation noted with individuals ranging from greyish or vinaceous brown to paler, sandy brown. Upperparts and wing-coverts rather plain, generally dark greyish-brown, minutely speckled dark brown; crown and scapulars sparsely streaked and spotted dark brown, spots star-shaped; no nuchal collar; small white patch on either side of lower throat; ­underparts paler than upperparts, often brownish or buff barred brown. Both sexes have white spot on four outermost primaries and narrow white tips to two outermost tail feathers. Iris dark brown, bill blackish, legs and feet flesh brown. Differs from more variable C. inornatus by white on throat and narrower white tips to two outermost tail feathers in male. Immature similar to adult but upperparts plainer and often rather rufous.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Possibly closest to C. inornatus. Species often treated as monotypic, but form simplex appears on balance to be probably worthy of recognition (1). Two subspecies recognized.

Subspecies

Monotypic.

Distribution

NW Somalia, Djibouti, C & S Ethiopia, SE Sudan and NW, N & C Kenya.

Habitat

Largely confined to dry, open bush and grassland, but also stony semi-deserts and black lava fields with densely scattered boulders, rocks and stones. Recorded from sea-level to possibly 1980 m.

Movement

None documented. Sedentary.

Diet and Foraging

Diet poorly studied. Feeds on moths, mantises, beetles and grasshoppers. Foraging methods not documented.

Sounds and Vocal Behavior

Song of male is a soft, yelping “pweu, pweu, pweu, pweu” or “pwe-eh, pwe-eh, pwe-eh”, given from ground, mainly at dusk and dawn. Flight call is possibly a guttural “churr-krrk”.

Breeding

Almost completely unknown. Possibly breeds Jan–Mar throughout range.
Not globally threatened. Locally common in Ethiopia, especially in S, e.g. possibly one of commonest nightjars in Nechisar National Park; rare in SE Sudan; locally common in NW & N Kenya, where occurs in Marsabit Nature Reserve. Probably not very common throughout remainder of E African range, but probably under-recorded.
