Nightjars (Caprimulgidae)

Little Nightjar (Caprimulgus parvulus) - HBW 5, p. 354

French: Engoulevent des bois German: Zwergnachtschwalbe Spanish: Chotacabras Chico

Taxonomy: Caprimulgus parvulus Gould, 1837, near Santa Fé, River Paraná, Argentina.
Formerly considered conspecific with C. anthonyi, but differs in vocalizations. Birds of Santa Marta region (N Colombia) have been considered a separate species, C. heterurus, again on basis of vocal differences, but these are normally considered insufficiently marked to justify such a split. Two subspecies currently recognized.

Subspecies and Distribution:

  • heterurus (Todd, 1915) - N Colombia and NW & CE Venezuela.
  • parvulus Gould, 1837 - E Peru through Brazil (S of Amazon) and S to N Argentina and Uruguay.
