Thanks Will.

I thought of the Irish tune called The Blackbird, after I posted this thread. I haven't heard blackbird song, either, but I just listened to it on an internet video.

I'll listen to all those works and I think I might have to retract my thread question.

The notes for the sixth piece by Olivier Messiaen is what I am getting at. He notated birdsong and then incorporated some of them into his works.

I'll have to hunt it down, but I have heard a birdsong related Australian orchestral work, however it seemed to be simply playing audio of birds singing while simultaneously playing "pretty" orchestral music. I only heard it once, and I might have to retract THAT statement as well, if I can find it again. LOL
