I don’t know what it is, but their call has always touched my heart. It lifts my head from the laundry or the dinner, from whatever grey worry I’m lost in, sending me on a dash to the window to try to catch a glimpse. The sound speaks of a longing to me, one that I recognise because autumn brings a restlessness to me too – to do more, to be more, with wistful thoughts of those longer summer days, a quiet dread of the dark winter looming.
