Thanks for explaining your previous comment, Guest:

"my issue is that a lot of musicians seem to think it's enough, for example, just to add some field recordings of birdsong to their work, without really exploring or interrogating it in any depth. Hence it becomes something of a cliche."

I respectfully agree with that, and that is the basis of what I said early in the thread, "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..."

Thanks for that information Jack Campin. I never knew that.

I just thought of a birdsong related song:
King's Singers - Of all the birds. The song starts at 30 seconds into the video.
