We think of nature documentaries as primarily visual works. As well we probably should, given the countless, mostly dull and uncomfortable hours spent in the field they demand of their photography crews. But what comes to mind when we imagine the sound of nature documentaries — apart, of course, from the voice of David Attenborough?

Listen closely during the breaks in his narration of such hit nature series as Planet Earth or Our Planet, and you’ll hear all manner of sounds: the sound of sharks swimming, of orangutans chewing, of spiders shooting their webs, of mushrooms sprouting. Hang on — mushrooms sprouting?
