This was near where I live, and happened last year:

I found this on google today while reading about swans. There is a family of 3 swans near my work building. I came out to get a picture of the cygnets (baby swans) and the male flew close to me in a quite aggressive manner. These are pretty big birds and I kinda jumped back when the bird flew at me. I would stay clear of them if I were in the water!
I don't understand why the guy in the article wasn't wearing a lifevest. Either be a better swimmer, wear a lifevest, or both, if you are going kayaking.
