Strange noise in recording (1 Viewer)

Hello! Testing the new Zoom H5 today, I find a noise that I don't know why. I attach an audio where you can hear that noise that occurs, and that you can hear well in 00:04, 00:07, 00:16, 00:28...
Why does that noise sound?

I'm thinking it might be the flight of the bats as it was getting dark... ?
Yes, they sound like bat wing flaps. I have similar wide-spectrum flaps in my Audiomoth recordings and, in those rare cases I have recorded ultrasound, it is associated with flaps. To get flaps the bat of course needs to be quite close to the recorder.

It sounds very like a bird call, with the quality of a thrush (sounds like a song thrush alarm call starting up, although much shorter and not developed), but without any location information it's hard to give that context.
