I've had a bit of a go at this, (although I didn't spend all that much time on it). One thing that challenged my expectations was that it seems you need a lot more data than you might think. Lots of species only have a handful of samples on Xeno-Canto, and the field recordings need aggressive processing in order to isolate the relevant parts, which is hard to do that in an automated way without inadvertently destroying lots of your valuable training data.
