Swiftlets Echolocation Capabilities

Echolocation Apart from using their eyesight for finding their way around their surrounding environments, swiftlets use echolocation (or sonar using sound and their echos) in order to penetrate, orientate and navigate in total darkness of cave interiors and swiftlet farms.


Echolocation is audible to human ears composed of a singular or series of brief, sharp clicks made by the swiftlets (like the click sound produced by knocking 2 pebbles together).

The resonance of these clicks then bounce of cave walls or the interior of swiftlet farms and are picked up by the great hearing capabilities of the swiftlets.

The time the resonance of the clicks take to return to the sharp ears of the swiftlets or the differences in frequency forms of the resonance when returning due to the different shapes and structures of the objects in front of them, allows the swiftlets to form a mental picture of when lies ahead of them in the darkness of the cave or swiftlet farm.

Only the Aerodramus Fuciphagus sub-species (double click per time) and the Aerodramus Maximus subspecies (one click per time) have echolocation capabilities. The types of sub-species of swiftlets that do not have echolocation capabilities have to navigate only through normal sight. These swiftlets do not inhabit dark areas like caves as they cannot navigate in the dark.

The echolocation capabilities of swiftlets is used in darkness only to negotiates bends, approaching walls or their nests, but is not complex enough to detect small objects like flying insects.
