Many bats hunt at night and use echolocation or sonar to zero in on their prey.

That slowed down 20 times so you can hear it.

But some insects like the tiger moth have figured out how to evade that echo. so you can hear it.

But some insects like the tiger moth have figured out how to evade that echo location,

by jamming it. It makes these ultrasonic clicks in the last moment before it would normally be captured by a bat.

And this interferes with the bat'sc location, causing that bat to miss.

Aaron Corcoran, a postdoc at Wake Forest University.

Corcoran studied that phenomenon and says he's now discovered that the jamming strategy isn't limited to prey.

Bats do it too, to foil each other's hunting efforts.

Corkrin and his colleagues recorded Mexican freetailed bats, to Derrida Braziliansis,

echo locating in the wild. And they happened to pick up a sound bats made only when other bats

were hunting. It reminded them of the moth jamming call.

So they played back that sound to bats hunting tethered moths in a field experiment.

And sure enough, bats who heard the bat jamming call while echolocating were 70% less successful at capturing the tethered moth

than bats who heard a generic tone,

or no sound at all.
