I'm glad to see that the project is going well, can't wait for more updates. Got a few questions though: 1) Different frog species croak differently, but how large is the variety of their calls within the same species? I.e. can you separate two different moss frogs and track their movement and make sure they not being counted multiple times? 2) If male frogs are the ones making calls and female frogs keep silent, how do you count them? Are you using some sort of empiric ratio to add the quiet ones?

If frogs' population is that small (50-1000 species occupying only a small territory), any sudden change in their environment may drive them to extinction, right? Is it possible to breed them in captivity thus creating a "backup" population and use it to restore the original one if needed?

Good luck with your project!
