Many birds, especially those that nest in cavities, are known to produce a snakelike hissing sound that may help deter predators at close range. [ 44 ] Some cave-dwelling species, including the oilbird [ 45 ] and swiftlets ( Collocalia and Aerodramus species), [ 46 ] use audible sound (with the majority of sonic location occurring between 2 and ...
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

[11] [12] [13] It is postulated that birds might use the detection of naturally occurring infrasound for long-range directional cues from distant landmarks, or for weather detection. [14] Since hearing tests at infrasonic frequencies have been conducted on a small number of bird species, the true diversity of this ability among birds is unknown.
