The cave swiftlet (Collocalia linchi) is a species of swift in the family Apodidae. It is found on the Indonesia islands of Sumatra, Java and Bali. It is a woodland species and nests in caves. The Bornean swiftlet was considered a subspecies, but is now usually considered distinct.
The cave swiftlet was described by the naturalists Thomas Horsfield and Frederic Moore in 1854 under the present binomial name Collocalia linchi. The specific epithet linchi is the Javanese word for a swiftlet.
There are three subspecies:
This bird is shiny blackish-brown above with a greenish gloss, including its rump; sometimes looks black and hooded. Chest black; belly to flanks pale grey with fine black speckles at margins. Wing tips are rounded; underwing is black. Tail black, rounded with shallow notch but lacking the white specks found in the very similar glossy swiftlet (Collocalia esculenta). A distinguishing feature between the two species is that the glossy swiftlet has a tuft of feathers on its hind toe but the cave swiftlet has a naked toe. It is 9 to 11.5 cm (3.5 to 4.5 in) in length. The call is a high-pitched "cheer-cheer".
The cave swiftlet is native to Malaysia and Indonesia. It is found in the Sundaic region, in Java, Madura Island, Bawean, Kangean Island, Nusa Penida, Bali and Lombok, parts of Sumatra, and the western slopes of Mount Kinabalu on Sabah, Borneo. Evidence of it occurring in Malaysia rests on a single specimen in the British Museum labelled "Molacca". Its natural habitat is lowland and upland forest and open woodland.
