As the flowers begin to bloom and the animals reappear after winter, nature’s choir begins to sound. Cerys Deakin explores changes to the sounds of spring that have occurred over time, and why.

When I was younger, I remember waking up to the sound of the birds in the morning. Some mornings, they even spoiled my sleep! Now I wake up to a different chorus. The sounds have changed, but how so?
The Guardian recently released an article that led me to think about this further. As the world faces a ‘deathly silence of nature’, I began to think as a conservationist.
What have we lost in recent years, that has vanished from our soundscape?

Studies have found that numbers of native breeding birds across the UK are decreasing, with a recorded 6% decline between 2017 and 2022, including pied flycatchers and tree sparrows. Various ecologists have reported that changes to the sounds of an environment reflect the changes in numbers of the wildlife. These sounds that are being lost are being referred to as ‘acoustic fossils’, and the collection of these fossils is growing. It is even said that there are already many sounds that have become fossils and can only be heard on recordings, instead of out in the wild where they belong.

Take the nightingale or turtle dove. The populations of both birds have suffered an almost catastrophic 90% decline. In an article published by The Guardian, one writer described having never heard either of these species’ song, with some people even being completely unaware that they are missing from both our land and soundscapes. In Cumbria, change is also apparent. Heidi Bewley recalls fifteen years ago, when the sound of the curlew reflected the start of breeding season, with dozens calling at once. Now, Heidi hears only the lonely call of a single Curlew.
