Swifts (Apodidae)

Waterfall Swift (Hydrochous gigas) - HBW 5, p. 425

French: Salangane géante German: Riesensalangane Spanish: Salangana Gigante
Other common names: Giant Swiftlet

Taxonomy: Collocalia gigas Hartert and Butler, 1901, Semangko Pass, Selangor, Malaysia.
Genus possibly closest to Aerodramus, and these two commonly merged into Collocalia; however, large size and differences in breeding biology favour isolation of present species, although some researchers have considered these differences marginal and of doubtful taxonomic significance; other opinions suggest present species may not be closely related to the swiftlet genera. Monotypic.

Distribution: Mountainous areas of Peninsular Malaysia, Sumatra, Borneo and W Java.
