Anna (Val's sister) took this gorgeous picture of a swan, elegantly swimming around Plansee, Austria. We were enjoying the evening on the lake shore, when Vinson and I had a close encounter with this very swan. He had this part of the lake to himself and apparently felt a little threatened by our wading in "his" lake.
When the middle picture (from the sequence of three) was taken, the swan was making a growling sound like a dog does to defend his food. I had no idea that swans had a tendency to be aggressive towards humans or that they could make growling noises like that. I still can't speak for swans generally, but this particular swan on this particular evening gave a cool show.
