On several nights I have heard an owl hooting in our backyard, and was hoping for a tool like this! Instead I ended up generating a list of several likely species and listening to the sounds of each on YouTube. Finally I was able to ID it as a Barred Owl, and sometimes we see it as a distant wingspan swooping low over the field behind our house.
You could use this app to correlate migrations and habitat ranges. Someday we could even use it to identify individual members of their populations. Imagine!
We are on the cusp of being able to track animal populations and health.
I think it could be cool to have an app that gives you a real idea of what lives around you and where (~15 deer, ~3 coyotes, 2 Cooper’s hawks, etc). Maybe one could monetize it to pest control agencies?
