Are you familair with the World Listening Project and the annual World Listening Day
Last year I tried to get a State-Wide group of Master Naturalists to participate and to make recordings if they were interested. I had limited but enthusiastic response so I will probably try again this year with a new a protocol.
I am a member of that group and am certified as a Master Naturalist in my home State. I am having a hard time getting these folks interested.
