Now, I will not claim that I have checked all the relevant literature in order to give away this title. It is just my observation and I am open to your suggestions about the winner.
“Vierwaldstättersee” in German – or Lake Lucerne in English – is the fourth largest lake in Switzerland. It is situated in the heart of the country, and its shoreline belongs to cantons Uri, Schwyz, Unterwalden and Lucerne. It has a very complex shape and seems to lie in four different valleys. It is an incredibly scenic place, that most resembles Norwegian fjords.
But there is one more thing about this place that is pretty remarkable. There is a huge diversity of waterfowl. I have seen only one sort of duck throughout the first twenty years of my life. When I came here I wished I could have my bird atlas with me. So make sure you have one with you!
On the only bird picture that I have taken on the day out in Brunnen one can see a bunch of species including one that is very rare. The pretty thing with white body, black wings and a little black cap is a Common Eider. It is a sea bird common in Northern Europe. Understandably, until recently this bird could be only rarely seen in Switzerland. However, during the second half of the 20th century thanks to the increase of the zebra mussel, there was sufficient food so that the birds increasingly spent the summer here. At the moment there are even a couple of breeding pairs in the country.
