The Philippine swiftlet (Aerodramus mearnsi, formerly Collocalia mearnsi) is a species of swift in the family Apodidae. It is endemic to the Philippines.

Its natural habitats are or tropical dry forests, tropical moist lowland forests, and tropical moist montane forests.

Description and taxonomy

Ebird describes it as "Uncommon dark swiftlet. Endemic to a smattering of the Philippines islands, from Luzon to Mindanao to Palawan. Habitat can be helpful in identifying this confusing species; generally favors ridges and slopes in montane and submontane areas above 700-800 meters. It is easily confused with the significantly larger Ameline Swiftlet, but the present species has a more squared-off-looking tail (fork is shallow and often unnoticeable), tends to fly lower and more erratically, and more often forms flocks. The combination of dark rump, unglossed dark back, and medium size separates this species from Gray-rumped Swiftlet, Pygmy Swiftlet, and Ridgetop Swiftlet. It frequently calls while in flight, giving a squeaky chattering twitter."{{Cite web |title=Philippine Swiftlet - eBird |url=https://ebird.org/ebird/species/phiswi1 |access-date=2024-09-08 |website=ebird.org |language=en}}

Breeds in May in Mindoro. Nests in caves and rock cavities. The nest is made of moss held together with saliva, where it lays four eggs. Breeding has been recorded in May in Mindoro.{{Cite journal |last1=Chantler |first1=Philip |last2=Boesman |first2=Peter F.
