Every year from February through to June, the early morning chorus of birdsong is one of the most evocative manifestations of spring. During late winter I open the bedroom window before going to sleep, to hear that incredible mix of flutes, whistles and chirps that begin before first light, when I wake. I listen for the layers of song that simultaneously come from close by and far away.
