Description

New study finds that some fruit bats can use sonar clicks from their wings to navigate in the dark !
Not only is this the first time that wing clicks have been shown to be used for echolocation, but it's also the first evidence of an animal using anything other than its vocal organs for this task, researchers report Thursday in the journal Current Biology. The discovery also leads scientists to think that some other bats might be doing the same thing.
The finding is even more surprising because the three fruit bat species with this ability weren't supposed to be able to echolocate at all, said Arjan Boonman, who conducted the study with neuroecologist Yossi Yovel at Tel Aviv University, in Israel. Although wing sounds have been previously reported in birds, those are used for display or communication, he said.
"It may be that all of the Old World fruit bats are capable of doing this, and nobody's ever looked before"
