Yes, I would see a new protocol with human listeners using recording =
devices as a tool to enhance their surveys.

I could see Audiomoths being used concurrently with the Nocturnal Owl =
Survey for a few years, just to correlate the two protocols, then =
converting over entirely to the Audiomoth protocol.

it would be fun to work on one.=20

Hi John,

That sounds like an interesting project.  I just bought an AudioMoth =
unit to try out and was thinking of buying a couple more.  I bought this =
one to put in forests to determine which birds are nesting in an area.  =
I'll be interested in hearing more about how you will be putting your =
units to work.
Agree -- I think community listening projects could be quite useful.
Our local facebook group has a few hundred members in the Annapolis =
Royal area and many are very interested in nature.  I'm quite sure we =
could get something going for listening for owls as many people are =
already doing so at their farms and rural residences.
I look forward to hearing more about how you'll be putting the AudioMoth =
units to use in your area.

Bev
