 1 Schulz, H. 1999. Der Weltbestand des Weisstorchs (Ciconia ciconia) – Ergebnisse des 5. Internationalen Weisstorchzensus 1994/95. In: Schulz, H. (eds)(1999) : Weissstorch im Aufwind? – White Storks on the up? Proc. Int. Symp. on the White Stork, Hamburg 1996 – NABU (Naturschutzbund Deutschland e.V.), Bonn : 335-350.




The reintroduction of the White Stork in Switzerland was started by Dr. Bloesch and the scientific aspects of this project were well covered. Most Swiss storks were ringed and the ringing recoveries were published in several publications (Jenni).


In the summer of 2000, 25 storks breeding or born in Switzerland were tagged with satellite transmitters (go to ‘more info’). All these birds followed the western route towards Spain, Marocco and western Africa. One bird tried to cross the Mediterranean Sea from France to Sardinia and later Tunisia, the bird failed to complete its voyage.


After the migration season in November 2000 there were still 11 out of 25 birds alive, which is 44%. At least 3 birds were killed after hitting electric wires or by electrocution. A fourth bird was injured after hitting an electric wire and subsequently died.




The Swiss storks spend the winter in Spain and western Africa. In November 2000, the tagged storks of the project S.O.S. Storch were wintering in Spain (8),  Mauritania (4) and Mali (1).
