Based on the information in wikipedia and Karin's reference book, the swans in Obertraun, as well as St. Wolfgang and Gmunden, where I have met them too, are the so-called mute swans.
The name 'mute' derives from it being less vocal than other swan species.
They are said to be monogamous and to often reuse the same nest each year, restoring or rebuilding it as needed. Male and female swans share the care of the nest, and once the cygnets are fledged, whole families can be seen looking for food. They eat both water plants and the grass.Though they are called mute, they can produce various sounds, like grunting, whistling, and snorting.
Snoring is very funny, they make this sound when they see the bread in the hands - they show their impatience to get it.

They do not seem to leave for winter, at least I always see them in Obertraun. Once I saw a swan on Wolfgang See in St. Wolfgang in winter-the lake was frozen that winter, it must have been hard for him to survive. I felt really awkward because he started to run in my direction on the ice, and I had no food to share.
Gmunden is famous for its numerous swans.
