Little nightjar
species of bird
The little nightjar (Setopagis parvula) is a species of nightjar in the family Caprimulgidae. It is found in Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay.
Taxonomy and systematics
The little nightjar was formally described in 1837 by the English ornithologist John Gould under the binomial name Caprimulgus parvulus. Gould did not specify a locality but the specimen had come from near Santa Fe, on the Rio Paraná in northeastern Argentina. The specific epithet parvulus is Latin meaning "very small". The little nightjar is now placed in the genus Setopagis that was introduced in 1912 by the American ornithologist Robert Ridgway. At various times what are now Todd's nightjar (Setopagis heterura) and Anthony's nightjar (Nyctidromus anthonyi) were considered subspecies of little nightjar, but it is now treated as monotypic. Molecular genetic analysis has shown that the little nightjar is sister to Todd's nightjar (Setopagis heterura).
Description
The little nightjar is 19 to 21 cm (7.5 to 8.3 in) long and weighs 25 to 46.5 g (0.88 to 1.6 oz). The male is generally grayish brown with buff, brown, and blackish brown spots and streaks.
Begin with the source’s own compact description: “Little nightjar” is species of bird. The dossier treats that line as a proposition to test through Little, nightjar and species, not as a finished interpretation.
Why this record matters
The phrase “species of bird” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Oct 2, 2025. The linked authority identifier is Q1264971. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1837 and 1912.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
