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 ...
A study by Nanjing Normal University in 2019 found that Sorex araneus is capable of echolocation via high-frequency tittering and close-range spatial orientation. Comparison of genes involved in hearing between bats , bottlenose dolphins and Sorex araneus suggests that this is a result of convergent evolution.
The common noctule uses two main calls for echolocation. The frequencies of the first are 26–47 kHz, have most energy at 27 kHz and an average duration of 11.5ms. [23] The frequency of the second call is 22–33 kHz, having most energy at 22 kHz and an average duration of 13.8ms. [23] [24] Common noctule in the Seeburgpark near Konstanz (Germany)
The greater noctule bat belongs to the suborder Yangochiroptera (family Vespertilionidae) and uses echolocation. Echolocation is a perceptual system where echoes are produced by emitting ultrasonic sounds. Echolocation allows bats to compare the outgoing pulse with returning echoes which produces detailed images of the bat's surroundings.
The barbastelle has two main call types used for echolocation. The frequency parameters of call type 1 lie between 30 and 38 kHz, have most energy at 33 kHz and have an average duration of 2.5 ms. The frequency parameters of call type 2 lie between 29 and 47 kHz, have most energy at 38 kHz and have an average duration of 4.1 ms. [18] [19] [20]
The use of echolocation was once used to separate Aerodramus from the non-echolocating genera Collocalia and Hydrochous (virtually nothing is known about Schoutedenapus). But recently, the pygmy swiftlet Collocalia troglodytes was discovered making similar clicking noises in and outside its cave. [ 6 ]
