UK Safari Tip:
Most bats fly after sunset so it's difficult to see them. A bat detector allows you to hear and identify the ones you sometimes can't see - click here

Although bats use echolocation to detect their prey, and find their way around in the dark, the sounds which they emit are 'ultrasonic', which is another way of saying they are beyond the range of normal human hearing. To help us listen to them, we can use a bat detector.


Bat DetectorA bat detector is a machine which listens to the ultrasonic sounds made by bats, and then converts them into sounds we can hear. Usually this comes out as a series of bleeps, clicks, pops and whistles. Each species produces a slightly different sound.

The bat detector has a frequency dial which can be tuned into the bat, just as you would tune a radio into your favourite station. By reading off the frequency on the dial when you hear the bat you can identify the species.

If you listen to the call in the sound clip above you'll notice that the speed of the clicks vary in speed. Sometimes they become so rapid it sounds like someone blowing a raspberry. This is the sound of the bat's echo getting shorter and shorter as it closes in on a moth or fly.
