The barred owlet-nightjar is a species of bird in the owlet-nightjar family Aegothelidae. It is found in New Guinea. The species was originally thought to be the same species as the Australian owlet-nightjar, until that species was found within the range of the barred owlet-nightjar. It was also considered to be the same species as the Vogelkop owlet-nightjar. There are three subspecies, the nominate, from south-eastern New Guinea, A. b. wiedenfeldi from northern New Guinea, and A. b. plumifer from the D'Entrecasteaux Islands.

The barred owlet-nightjar is a small, nocturnal insect-eater endemic to New Guinea, often roosting by day in tree hollows. Its heavy barring and pale eyebrow give it a subtly owl-like face, though it is neither an owl nor a true nightjar. It was once confused with the Australian owlet-nightjar and the Vogelkop owlet-nightjar but is now recognized as distinct, with several subspecies across New Guinea. It hunts by sallying from perches to snatch moths and other insects in low, agile flights.
Temperament
secretive and nocturnal
Flight Pattern
short rapid wingbeats with agile, low sallying flights
Social Behavior
Usually solitary or in pairs, especially during the breeding season. Nests in natural cavities or rotting stumps, with minimal nest material. Clutches are typically small, and both parents are thought to share incubation and chick-rearing duties. Roost sites may be reused across seasons.
Migratory Pattern
Resident
Song Description
Vocalizations are soft but far-carrying trills, repeated whistles, and short series of notes delivered at night. Calls often begin at dusk, with relaxed sequences that can accelerate during territorial interactions.
