(I've tried listening to one of those birding tapes but have had difficulty pretending I'm in the woods--no matter how accurately the calls are recorded, I have trouble making myself believe it's a real bird making that call when there is no other accompanying stimuli of the natural world: no odor of marsh or spruce, no slant of sunlight or dimming of dusk; no breeze, no grass rustle, no sky, no earth, and I have to confess also to becoming frustrated with the pace of the narrative on those tapes.
