I started paying attention to birdsong ten years ago and now I am fully tuned in. I record it and try to transcribe it but it is very complex and doesn't always correspond to conventional western musical notation so I have developed a supplementary system for doing so. Even when I am not recording or transcribing I am listening. I don't seek it out but birds are everywhere so I don't have to.
It feels like another aspect of life has opened up for me. Does anyone else do this?
