The rufous nightjar (Antrostomus rufus) is a species of nightjar in the family Caprimulgidae. It is found in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guyana, Panama, Paraguay, Peru, Saint Lucia, Suriname, Trinidad and Tobago, and Venezuela.
The rufous nightjar was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle that was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Caprimulgas rufus in his catalogue of the Planches Enluminées. The rufous nightjar is now placed in the genus Antrostomus that was erected by the French naturalist Charles Bonaparte in 1838. The generic name combines the Ancient Greek antron meaning "cavern" and stoma meaning "mouth". The specific epithet is Latin for "red".

GBIF citizen-science records
It is estimated from how often the Rufous Nightjar is recorded against all the birds logged in Henri Pittier National Park (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
