Fascinating challenge! Might not be nature but interesting and related,
in the sense of hazrds to nature.
Have you tried shotgun mics? PZMs on the ground durectly under them?
Can you pinpoint exactly where? I'd love to give it a go someday. I'm
in Marin so it isn't far.

And, under unusual conditions, with winds aloft but
calm at the surface, you can actually hear them
rotating. Kind of a low-frequency 'whoosh....
whoosh.... whoosh....'.
So, I thought. Very cool, I *have* to get a recording
of this.
What is the result? Pretty much every sound in the
environment -except- these blades.
I know I can hear them-- so why can't the microphone,
which can hear everything else?
Has anyone else encountered such a thing? What kinds
of things can you do to pick these things up? They are
sounds, but they are getting pretty close to 'pressure
waves', or subtle changes in background. Thing is, I
can hear them clear as day... so what to do?
