I am curious as to what different people enjoy listening to from the natural world, like bird song or gurgling brooks! I must say the most comforting thing for me to listen to would be the silence of the wind. When you go out into a plain or field or dirt road and you close your eyes and listen... It's a whole other kind of magic that gets me right there. To me the sound of the wind is the essence of adventure, a sound connected to every fantasy novel, where anything could happen in a world you have yet begun to understand.
