The Karimui owlet-nightjar is a species of bird in the owlet-nightjar family Aegothelidae. It is found in montane eastern New Guinea.
Region
Eastern New Guinea Highlands
Typical Environment
Primarily inhabits montane and upper hill forest, including mossy forest, forest edges, and gaps. It favors areas with mature trees that provide natural cavities for roosting and nesting. Secondary growth adjacent to intact forest is also used for foraging. Most records come from rugged terrain where access is limited, contributing to its elusive reputation. It is likely under-recorded due to nocturnal habits and dense canopy cover.
Altitude Range
900–2000 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
A secretive, nocturnal owlet-nightjar of montane eastern New Guinea, it is most often detected by voice rather than sight. It roosts by day in tree cavities or dense vegetation and emerges at dusk to hunt flying insects. Like other owlet-nightjars, it has prominent facial bristles that aid in sensing prey near the bill. Its restricted highland range makes it of interest for conservation monitoring.
Temperament
solitary and secretive
Flight Pattern
short rapid wingbeats with brief, agile sallies
Social Behavior
Typically encountered alone or in pairs, especially during the breeding season. Nests in natural tree cavities or old woodpecker holes, lining the chamber with plant material. Both parents likely share incubation and chick-rearing, as in related owlet-nightjars.
Migratory Pattern
Resident
Song Description
A series of soft whistles and trills delivered at dusk and during the night, often repeated at intervals. Calls can be ventriloquial and carry through valleys, making precise location difficult. Alarm notes are sharper and more clipped.
Plumage
Mottled and barred brown, grey, and buff with fine streaking that provides excellent camouflage against bark and moss.
Diet
Feeds primarily on nocturnal insects such as moths, beetles, and orthopterans. Takes prey by sallying from low to mid-level perches and by short aerial hawking along forest edges and gaps. May also glean insects from foliage and trunks when opportunities arise.
Preferred Environment
Forages along edges of mossy forest, along streams, and in small clearings where insect activity is concentrated. Often hunts under the canopy where scattered moonlight or gaps aid visibility.
