While making a birding trip in Preiviiki Bay area, I merely of an accident made a short walk into a remote place with reed, some small birches and alders. The wind was hitting this seemingly uninteresting bush rather strongly, and I bowed down to have some shelter while listening for yoking Whooper Swans longer out on the bay. Surprisingly, there was an interesting soundscape, as the speed of the wind was clearly audible while wiping through the leafless branches. The wind has different frequencies between the trees and the weed, and the speed of the wind is distinguished if you listen with headphones.
