About the Cave Swiftlet

The cave swiftlet or linchi 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 four recognised subspecies:

C. l. dedii Somadikarta, 1986 - Bali and Lombok C. l. linchi Horsfield & Moore, F, 1854 - Bawean and Java C. l. ripleyi Somadikarta, S, 1986 - Barisan Mountains, Sumatra C. l. dodgei Richmond, 1905 - Mt Kinabalu (Sabah), in N Borneo. (now a full species: Collocalia dodgei)

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... Wikipedia →
