2. Animal echolocation - Wikipedia

   en.wikipedia.org/wiki/Animal_echolocation

   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 ...

3. Bat - Wikipedia

   en.wikipedia.org/wiki/Bat

   Principle of bat echolocation: orange is the call and green is the echo. In low-duty cycle echolocation, bats can separate their calls and returning echoes by time. They have to time their short calls to finish before echoes return. [95] The delay of the returning echoes allows the bat to estimate the range to their prey. [93]

4. Greater mouse-eared bat - Wikipedia

   en.wikipedia.org/wiki/Greater_mouse-eared_bat

   The Greater mouse-eared bat is relatively large for a member of the genus Myotis, weighing up to 45 grams (1.6 oz) and measuring 8 to 9 cm from head to tail (a little larger than a house mouse, Mus musculus), making it one of the largest European bats. [3] It has a 40 cm wingspan, with a forearm length of 6 cm, and a 4 to 5 cm long tail.

5. Echolocation jamming - Wikipedia

   en.wikipedia.org/wiki/Echolocation_jamming

   Bats can make this adjustment very rapidly, often in less than 0.2 seconds. [9] Big brown bats can avoid jamming by going silent for periods of time when following another echolocating big brown bat. [10] This sometimes allows the silent bat to capture a prey in competitive foraging situations.

6. Microbat - Wikipedia

   en.wikipedia.org/wiki/Microbat

   Laryngeal echolocation is the dominant form of echolocation in microbats, however, it is not the only way in which microbats can produce ultrasonic waves. Excluding non-echolocating and laryngeally echolocating microbats, other species of microbats and megabats have been shown to produce ultrasonic waves by clapping their wings, clicking their ...

7. Bechstein's bat - Wikipedia

   en.wikipedia.org/wiki/Bechstein's_bat

   The frequencies used by this bat species for echolocation lie between 35 and 108 kHz. Its echolocation calls have the most energy at 61 kHz, and have an average duration of 3.3 ms. [11] [12] Most of its echolocation is in the 50–60 kHz range.

8. White-striped free-tailed bat - Wikipedia

   en.wikipedia.org/wiki/White-striped_Free-tailed_Bat

   Individuals have a mass of 33 to 41 grams, and average of 37 g, and a head and body length of 85 to 100 millimetres. [6] The free tail extends 40 to 55 mm from the body and can be folded during high speed flight to reduce drag. [9] [10] The forearm length range is 57-63 mm. [6] It has a condylobasal length of 23–24 mm. The skull is dorso ...

9. Australonycteris - Wikipedia

   en.wikipedia.org/wiki/Australonycteris

   Australonycteris clarkae, one of the earliest bats in the fossil record, is known from several upper and lower teeth, an edentulous lower-jaw fragment, a partial periotic bone, and several postcranial fragments. It has a forearm length of 40–45 millimetres (1.6–1.8 in), making it a medium-size bat species, and it could echolocate.
