I’m really impressed about how well the sound ID works for birds doing mimicry.
We had a brown thrasher stringing together a long series of mimicked calls that got labeled correctly as a brown thrasher.
I don’t even know how you’d approach the ML for that seeing how unique each song is to each bird
Equally so I've had a red wing black bird mimic a cardinal and it appeared as a cardinal.
The waveform was too thick and looked funky which is why I tracked down the bird doing it. (I Was at the Ohio bird sanctuary)
