Most likely a Leisler's Bat (Nyctalus leisleri). Recorded with an unattended Audiomoth at 02:38 on 15th June, 2023. The recording was made with a sample rate of 384kHz, which was resampled down to 44.1kHz to make the sound audible in Audacity and further edited in Ardour to reduce the timing by about half but this is still stretched out compared with the original.
Another version using the same original file but with the timing closer to the original can be found here: https://freesound.org/people/naturenotesuk/sounds/702992/
If this sound has been of help, and you are able, please consider donating to Freesound, https://freesound.org/donations/donate/
Thank you
