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.
