Habitat Comparison
Song & Call Comparison
Plain Nightjar
Monotonous churring trill; steady 'churrrrr' from African savanna; calls persistently at night; plain plumage matched by relatively unvaried, repetitive song
Cayenne Nightjar
Poorly known vocalizations; presumed churring trill based on genus; extremely rare recordings; distinct from other Setopagis by subtle tonal and rhythm differences
Geographic Range & Migration
Plain Nightjar
Found from Ethiopia and Somalia south to Kenya and Tanzania. Resident in arid acacia scrub and dry open country. Closely related to Nubian Nightjar.

About These Birds
Plain Nightjar
A small nightjar (21-23 cm) of arid and semi-arid zones across the Sahel belt of Africa, from Senegal to Somalia. Pale sandy plumage with minimal markings. Nocturnal insectivore, feeding on beetles and moths. Nomadic movements tied to seasonal rainfall patterns.
Cayenne Nightjar
A small Caprimulgidae nightjar (~47 g) from coastal French Guiana and adjacent Suriname. Known from only a handful of specimens; biology essentially unknown. Mottled brown plumage presumed cryptic in leaf litter. Presumed nocturnal insectivore. Data Deficient due to extreme rarity of confirmed records in the wild.
