pound in summer hydrophone 1339 220725_0457.wav

The underwater summer sound of a small pond in a village in the Netherlands.

The cricket sound comes from a tiny water insect called a Lesser Water Boatman ( Micronecta Scholtzi, Corixa punctata ). One of the noisiest animals on earth compared to its body size. More info about how this animal makes this sound: https://www.biologicaldiversity.org/news/center/articles/2011/bbc-06-30-2011.html

The sound that resembles a dripping water tap is the sound of oxygen produced by the aquatic plants as a result of the sunshine. Sometimes gas also comes out of the bottom, but that is only for a short time.

The rattling sounds comes probably from a Notonectidae, a backswimmers because they swim "upside down". Many of you know him. See the picture below.

The slow scratching sound that resembles the scratching with your fingernails on wood is probably from an eating freshwater snail.
