Aerodramus vulcanorum
The Volcano Swiftlet, Aerodramus vulcanorum, is a fascinating avian marvel endemic to the volcanic peaks of Java and Sumatra. Measuring approximately 12-14 cm in length with a robust, streamlined body, this swiftlet exhibits a uniform dark sooty-brown plumage, often appearing black against the sky, with a slightly paler, often grayish, throat and belly. Its tail is subtly notched, distinguishing it from deeply forked swallows. As a member of the genus Aerodramus, it is one of the few bird spe...
This species exclusively inhabits montane forests and volcanic caldera environments, typically at elevations ranging from 1,000 to over 3,000 meters. It primarily utilizes deep volcanic caves and tunnels for roosting and nesting.
The Volcano Swiftlet is an obligate aerial insectivore, feeding primarily on a variety of flying insects, including beetles, flies, ants, and moths, caught on the wing.
Volcano Swiftlets are highly aerial and diurnal, spending the majority of their active hours continuously foraging in flight. They form large, noisy colonies, often numbering in the thousands, which roost and breed deep within the absolute darkness of volcanic caves. Their remarkable echolocation...
The Volcano Swiftlet is endemic to the Indonesian islands of Java and Sumatra, where its distribution is strictly localized to specific mountainous and volcanic regions. In Java, populations are found on prominent volcanic peaks such as Mount Salak, Mount Gede, Mount Slamet, and Mount Semeru. In ...
Least Concern
- The Volcano Swiftlet is one of the few bird species globally capable of echolocation, a trait shared with bats and some cetaceans. - They emit distinct clicking sounds (not audible to humans) to navigate the pitch-black interiors of volcanic caves. - Their name "vulcanorum" directly refers to t...
