What is a Swan Song?

The phrase Swan Song refers to a very old belief that the Mute Swan, Cygnus olor, is totally mute during its lifetime – up until the moment before it dies when it sings one beautiful song before death. We know today that Mute Swans aren’t really mute during life as they do produce snorts, shrills, grunts and they even hiss, but the do not sing as they die. No, they do not bid their earthly world good bye with a beautiful song of farewell. In A.D. 77, Pliny the Elder refuted it saying, observation shows that the story that the dying swan sings is false!
