Can iBird identify birds bysong like Shazam?
A “bird song identification app” is now reality. My company, Avelgood Apps, has

free to download. You can read more about Twigle on our website http://www.twigle.it and also like us on our Facebook page to get updates on Twigle’s launch; https://www.facebook.com/avelgood

And since digital music is like a finger print the comparison process can be very accurate. Bird calls and songs on the other hand are more complex than human speech. Not only does every species have a repertory of sounds – no two birds sound alike. Indeed the same species of bird in the same area can have different dialects.

For that you need a special parabolic mic and a high gain amplifier with filters to remove noise. There are other reasons that make this difficult that are fairly technical So while we expect someday this will be fea
