Bats Find Their Way With Superfast Vocal Muscles
The last thing an insect hears before it is eaten by a bat is what scientists call the terminal buzz, a sonar-based call that bats use to track their prey. Bats can produce these echolocation calls at a rapid rate, up to 190 calls per second; they also use the buzz to navigate.
It was never known precisely how they produced these calls so quickly. But now scientists are reporting that bats are able to make these calls thanks to superfast vocal muscles; they are the first mammals known to have this type of muscle. The muscles are very weak, but so quick that they can contract 100 times as fast as ordinary human muscles and 20 times the speed of humans’ fastest muscles, the ones in the eye.
Until now, superfast muscles had been found only in songbirds, rattlesnakes and certain fish, all of which use them to produce sound. Researchers at the University of Southern Denmark and the University of Pennsylvania wanted to see if they existed in mammals as well, which led them to look at Daubenton’s bat, a species found throughout Europe and Asia.
“I thought, ‘If we’re going to find them in mammals, it’s going to be bats,’ ” said an author of the study, Coen Elemans, an assistant professor at Southern Denmark. “If you hunt prey that is fast-moving and also evading you, it’s very important to produce these calls at a very, very high rate.”
In their study, which appears in Science, Dr. Elemans and his colleagues recorded the bats’ calls and determined when the echoes reached their ears. The scientists found that the bats’ brains could process the sounds even faster than their muscles could generate them: up to 800 calls per second, in some cases, before the calls would start to overlap with the echoes and cause confusion.
