I used it in the middle of (light) bavarian forest, and it worked quite well. It had some misdetections, but overall it worked to identify all birds I could hear. Don’t know how well it works in the middle of a city, or in other parts of the world.
But if you remind me in about four weeks, I can give a review of how it worked out in southeast asia.
Fascinating, Duckduckgo isn’t working for me aswell.
