I'm really liking these audiomoths. Broadband recording at high fidelity with long, unattended recording possible. I'm trying to see whether I can identify individual crows among a family of pecan-stealers active in my area. I almost have them accustomed to checking my porch for raw peanuts as part of their regular rotation. I probably need cameras to be able match the bird to the call and identify individual birds and I don't yet have that but I will in time. For now I am getting familiar with all the normal noises out here and the frequencies they occupy so that I can visually separate bird calls at various frequencies from ambulances, airplanes, helicopters, automobiles, barking dogs, etc so I can spend more time analyzing interesting signals from the birds out here.

If you have time to acquire a new hobby, an audiomoth is a great tool.
