Late last autumn I saw theese nests at lake Lützelsee here in Switzerland. I saw many herons around and thought it might be a heron colony, but stork nests also came into mind. They are stork nests! About twenty of them in two giant trees. Lützelsee is a ”Naturschutzgebiet” and can apparently support so many birds by it´s surrounding wetlands. Here, the Earth is happy !
