About These Birds
European Nightjar
A medium Caprimulgidae nightjar (~76 g) breeding across Eurasia from Britain to central Siberia in open heath, scrub, and pine plantations. Males produce a sustained mechanical churring song at dusk. Long-distance migrant wintering in sub-Saharan Africa. Feeds on moths and beetles. Least Concern despite local heathland declines.
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.
