It was a while ago, but it keeps coming back to me.
I live near the reservoir in Bremgarten AG. At the end of July/beginning of August I was on holiday for two weeks. When I got home I immediately noticed that the swan family was no longer complete: of two adult swans and two young ones (they were already bigger than ducks), only one adult swan is left. I also noticed that the seagulls have completely disappeared.
I go for a lot of walks along the Reuss, or rather, along the reservoir. On my first walk after the holidays I found the photographed note.
Do you think it was a person who made the birds disappear? Why?
Could it be just nature by itself?
Could it be related to the dam (this is about 300m further down)?
What do you think? Is there an expert with an explanation here by any chance?
