In the dark, bats identify each other by voice Jeremy Hance mongabay.com June 08, 2009
Researchers from the University of Tuebingen, Germany found that the greater mouse-eared bat could distinguish between their fellows’ echolocation calls. A subject bat was tested by having to select between two others depending on their calls. The subject bats chose correctly over 80 percent of the time.
Researchers then produced a computer model that reproduced the recognition behavior displayed by the bats. The model suggests that the bat’s calls contain spectral energy distribution that is unique to every individual, allowing the bats to tell one another apart simply by listening.
