Taxonomy
This is a monotypic species.
It was formerly included in Moluccan Swiftlet, together with Seram Swiftlet and Sulawesi Swiftlet.
Forms a superspecies with Philippine Swiftlet, Mountain Swiftlet, White-rumped Swiftlet and Australian Swiftlet. Also considered to be conspecific with White-rumped Swiftlet. Relationsships in this group are still poorly understood.
Like other Aerodramus Swiftles this species is often placed in Collocalia.
Habitat
Moist lowland forest and montanes. Generally higher than other Swiftlets.
Behaviour
Feeds on insects, taken in flight. Noted to feed above canopy while Glossy Swiftlet is feeding beneath canopy level.
Not much information about nesting. Believed to make a nest with vegetable matter, attached to a cave wall.
Thought to be resident or nomadic within range.
