This week's selection comes from Cheryl Tipp, Curator of Wildlife & Environmental Sounds.
Have you ever wondered what a pond sounds like? Most of us will have spent some time dipping for tadpoles, watching insects glide across the surface or looking out for flashes of colour as fish move beneath the water, but our interactions with ponds are usually visual. For some people though, the promise of what's going on sonically is just too hard to resist.
Most wildlife sound recordists will have a hydrophone somewhere in their arsenal and are only too happy to investigate this otherwise silent world. While visiting a smallholding in north Wales, Peter Toll's curiosity was piqued by a little pond that had been carefully created to give life to as many creatures as possible. In his accompanying notes, Peter remarked:
"It looked so still and tranquil above the surface, until I lowered my hydrophones and was truly amazed by what sounds I could hear below the surface."
What Peter heard was an ecosystem brimming with life. The sounds of newts, invertebrates and oxygenating plants came together to create a vibrant aquatic soundscape, as can be heard in the following excerpt. As the old adage goes, looks can definitely be deceiving.
