That's interesting henrya, I recorded Common pipistrelle last night within a wall roost making a sound I've never heard before, like a machine gun at 22 kHz. It never emerged during the one hour after sunset but at 06:19 this morning re-entered the same roost.
Others in the same property were using four different emergence points and social calling - "chonking".
I'll see if I can download the file later.
excoriate - if I could give you some well meant advice - look after your hearing. I wish I had done so at 26 and beyond. |
