The Philippine Swiftlet is a small swiftlet found in the mountains of the Philippines. It has a shallowly forked tail and is often seen in flocks.
Its upperparts are dark brown, with a similarly colored rump and paler brown underparts. The tail has a slight fork.
It occurs along ridges and slopes in montane and submontane areas, generally above about 700–800 m. It is more often seen in flocks than the similar Ameline Swiftlet and gives thin, high calls.
Breeding is recorded on Mindoro in May. Its cave nest is a shallow saucer of moss bound with saliva that hardens.
An adult female collected in Benguet, Luzon, in July 1907 had a faint green sheen above, green or violet reflections on the wings and tail, and smoke-grey underparts.
