I don't know a software approach, but I strongly recommend reading a
book called "The Singing Life of Birds" by Donald Kroodsma.
Fascinating stories (based on US species, but the principles apply
globally) he describes a manual approach based on spectrograms. CD
included so you can hear what he is writing about.
