In my garden there are Blue Tits. They give me a lot of joy and are tough and fearless. They live in the forest. The bird sound in the first is from Naturvernforbundet otherwise the sound is from the different birds in my garden. These were registered in Norway in 2017. http://www.fuglevennen.no/aktiviteter/foringsplassen/resultater/?periode=hagefugl%2F2017 Find out how the different birds sound https://naturvernforbundet.no/naturvern/fuglesang-article16236-149.html I want lower limit values for electromagnetic radiation. The insects do not tolerate much electromagnetic radiation. Without the insects, the birds disappear. Filmed and edited by Solveig Løvhaug 2018.
