About These Birds
Scrub Nightjar
A small Caprimulgidae nightjar (~36 g) of arid coastal scrub and thorn-scrub in southwestern Ecuador and northwestern Peru. Pale sandy-buff and brown plumage suits its xeric habitat. Closely related to the Pauraque but smaller and paler. Nocturnal insectivore; calls at dusk. Least Concern in its limited range.
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.
