Gives a musical bugling 'boo-boo-boo' in flight and softer honking on water. Less vocal than Mute Swan; produces a baying call when alarmed. Wings whistle softly in flight.

About These Birds
Pink-footed Goose
A compact short-necked goose with a pink-and-black bill, pink feet, and warm brown-grey body. Breeds in Greenland, Iceland, and Svalbard; winters in northwestern Europe. One of Britain's most spectacular winter visitors; massive roosts of over 200,000 birds occur in Scotland.
Trauerschwan
Der Trauerschwan galt Europäern, die glaubten, alle Schwäne seien weiß, einst als unmöglich, was ihn zu einem berühmten philosophischen Beispiel für das Scheitern induktiver Schlussfolgerungen machte. Er ist das Wappentier von Western Australia. Trauerschwäne gehen lebenslange Paarbindungen ein, und beide Elternteile teilen sich das Brüten und die Aufzucht der Jungvögel.
