Hi Boyd and all,

Interesting question. As an experiment, I opened a Superb Fairy-wren's call in 
Praat (a free program which I use for speech analysis at work) and looked at 
one second - now, I'm used to analysing human speech, not bird song (though I'd 
love to) so I'm not sure what constitutes a whole note - but one way I did it 
there were 8 notes in the second I had selected and the other way, if I counted 
all the peaks, there were 21.

Is there anyone out there with bioacoustics knowledge who can shed some light 
on how to read a waveform? I know there's a program called Syrinx but I'd find 
it easier using one I know, although it's admittedly designed for human speech, 
so wouldn't pick up all the frequencies. The answer is probably very obvious 
but never having analysed this type of sound before I'm curious to understand
