This recording was taken on one of the walking paths on Vogelinsel (=birdisland) at the Altmühlsee (a lake) in Germany, which is a nature reserve. The microphone was mounted on a stand. On both sides of the path is water - behind there is a small pond and in front of the mic-direction a big lake. All around this, there are other small islands. The Lake was frozen the Day the Recording was made so you can hear cracking and squeeking sounds from the ice throughout the recording. Also the frozen Surface reflected the Sounds of the environment leading to a more harsh and brittle soundscape. Compared to the previous Recording in January 2018 there are far less bird sounds on this recording. At the end of the recording you can hear a beaver gnawing on a tree. Those sounds are mixed up with far away traffic sounds from the streets and the village nearby. Unfortunately due to technical problems a loud crackling and popping noise was recorded to channel 4 for the first hour of the recording.

Secondary Authors: Cornelius Pöpel, Carla Banai-Schoneweg.This recording was made in the park Yerba Loca, about 2 hours drive from Santiago. We went with the car as far as possible, then went by foot. The recording was done close to a huge stone. There were bushes and some trees close to the recording spot. There is a river making a lot of sounds. We went far away from the river to keep water sounds and their masking small. One can hear birds as well as the river and cows from far away.

This recording was taken on one of the walking paths on Vogelinsel (Bird Island) at the Altmühlsee (Lake) in Germany, which is a nature reserve. The microphone was mounted on a stand. On both sides of the path is water, behind there is a small pond and in front of the mic-direction a big lake. All around this, there are other small islands. Because it was a sunny winter day, there were many people going out for a walk, which you can also hear on the recordings. Besides that, the wind was at some points unexpectedly strong, causing a few noises of the stand. You can also hear a mechanical creaking noise which was not produced by the stand but by reeds moving in the wind. Especially after sunset you can heat a higher intensity of bird sounds. Those sounds are mixed up with far away traffic sounds from the streets and the village nearby.
