What the bird… #6: Mute Swan
Again – the Mute Swan normally is just “the swan” and actually the only Swan we have. As winter guests on Lake Constance we do have other all-white Tundra- and Whooper Swans with partially yellow beaks.
When I was still little I always thought that the nose hole is the eye. And my mother told us the story that the swans are married if they are wearing a ring. Today she says that she never would have said something like this and maybe I heard the story somewhere else or I invented it myself.
In German the Mute Swan (cygnus olor) is called Swan with knuckle (Höckerschwan). It isn’t really mute – it can grunt and its wings creak when flying. So the mute is probably to show the difference to the Whooper Swan (called Singing Swan in German) – but I have never heard one of these and so I can’t say anything about it.
