About These Birds
Long-trained Nightjar
A large Caprimulgidae nightjar (~111 g) of subtropical Atlantic forest and open country in southeastern Brazil. Males have extraordinary forked tails extending far beyond body length. Inhabits forest edges and clearings in Atlantic Forest remnants. Feeds on moths and large insects. Least Concern; some decline with deforestation.
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.
