Nature’s secret soundscape: listen with me to the world’s quietest creatures

While humans are more boisterous than ever, other species are talking too - this is what you will hear if you really listen

It's a spring day in northern Sweden, just 100km (62 miles) below the Arctic Circle. I tuck my sound gear into my backpack, clip into my cross-country skis and glide out on to a frozen lake, looking for a small ice-fishing hole.

It's a quiet day, with no snowmobiles or other skiers about. Conditions are perfect for the fishing I hope to do: not for dinner, but for sounds.
