have automatic identifiers for a few spec 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.
