  • Description

    Cave swiftlet Cave Swiftlet Collocalia linchi

    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".

    Distribution and habitat

    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.

    Behaviour

    Cave swiftlet Cave swiftlet Wikipedia

    The cave swiftlet is highly gregarious and flies with all the other species of swift that are sympatric with it. It often circles and flies through the branches of trees emerging through the canopy such as fruiting figs. It breeds in the lighter parts of caves, building a nest of stringy vegetation and cementing the materials to the rock with saliva. Two white, somewhat elongated eggs are laid.

    Status

    The cave swiftlet has a very wide range and is common in Java and the nearby islands. It has no particular threats and the IUCN has listed it as being of "Least Concern". Although the overall population may be declining slightly, this is not believed to be at such a rate as would justify listing it in a more threatened category.
