Bonaparte's nightjar, also known as the Sunda nightjar, is a species of nightjar in the family Caprimulgidae. It is native to the islands of Sumatra, Belitung and Borneo. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Region
Sundaland (Sumatra, Belitung, and Borneo)
Typical Environment
Occurs in evergreen lowland forests, peat swamp forests, kerangas (heath) forests, and forest edges. It also uses secondary growth, riverine corridors, and clearings within otherwise forested landscapes. Often found near open glades, tracks, and along edges where flying insects concentrate. It avoids high montane zones and heavily urbanized areas.
Altitude Range
0–800 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
Bonaparte's nightjar (also called the Sunda nightjar) is a cryptic, ground-roosting nightjar that blends almost perfectly with leaf litter. It is largely crepuscular and nocturnal, catching insects on silent, buoyant wings. A wide gape fringed with bristles helps funnel flying prey into the mouth. Ongoing loss of lowland forest and peat swamp habitat is the main threat.
Temperament
secretive and crepuscular
Flight Pattern
buoyant, silent flight with short rapid wingbeats and brief glides
Social Behavior
Typically solitary or in pairs outside the breeding season. Nests directly on the ground on bare leaf litter, usually laying a single egg with no constructed nest. Adults rely on camouflage and distraction displays to deter predators. Males sing from low perches or open edges at dusk.
Migratory Pattern
Resident
Song Description
A soft, repetitive churring trill interspersed with clear ticking notes, often delivered persistently at dusk and during the night. Calls carry well in still forest air and may accelerate in short bursts during displays.
