Non-bat Sounds
A whole world of ultrasound opens up when a bat detector is switched on. To distinguish bat and bat species it is important to recognise non-bat species. The following minimally edited recording was made in a small nature reserve in North Devon, UK, in September. None of these calls were audible normally.
However, the cheat here is that the last sound is from a bat which is making a social call as it flies.

Délira knew no other types of songs. She didn’t sing loud, and the song had no words. It was sung with closed lips and it stayed down in one’s throat.... Life is what taught them, these Negresses, to sing as if they were choking back sobs. It is a song that always ends with a beginning anew because this song is the picture of misery, and tell me, does misery ever end?” |
