The call that comes back as a map A bat leaving its roost at dusk emits ultrasound pulses at frequencies between 20 and 200 kilohertz, well above the ceiling of human hearing, which tops out around 20 ...

Bats are nocturnal hunters and use echolocation to orientate themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls’ reflections. Yet, they have retained ...

It’s now well-established that bats can develop a mental picture of their environment using echolocation. But we’re still figuring out what that means—how bats take the echoes of their own ...

Karen Hopkin: Bats rely on echolocation to navigate the night skies and to chase down and capture even erratically moving prey. But even more impressive than their aerial acrobatics are the mental ...
