Common Pipistrelle bat: Bats hunting along a quiet country lane
Common Pipistrelle bat This clip has been edited to reduce the the pitch and speed by a factor of
10. The bat's social calls are heard first, then (after a quiet period) two
louder social calls are heard and now the bat is also echo-locating.

Noctule (with Pipistrelles and Myotis in the background) Bats hunting along a tree line at the side of a large lake.

The second clip was produced by reducing the pitch and speed by a factor of 10 to emphasise the calls of the Noctule bat.
You may think that some of the bat recordings sound like the flapping of the bat's wings, but all of the sounds are the echo-location and feeding/social calls
