Firstly, ı want to give some information about the national bird of Denmark: the Mute Swan
The National Bird of Denmark is the Mute Swan (Cygnus olor) or Knopsvane (of course), made famous in the story by Hans Christian Andersen, "The Ugly Duckling".
In the 1920's the Mute Swan was nearly extinct, until in 1926 it became a protected species and has now regained its population and is seen all over Denmark and most of northern Europe.
They breed in colonies all over Denmark and are a magnificent bird to see.
At an early age the Mute Swan or cygnet is not always white and is usually an off-white, grey or brownish tint. Their beaks/bills are black and it is not until after their first year that they turn all white and the beak/bill gets its orange color.
This is where the Hans Christian Andersen story has its origins. Many Mute Swans are ugly ducklings – some cygnets are white, but most are not - but all Mute Swans are white when they mature.
And that is the story of the National Bird of Denmark.
The Mute Swan (Cygnus olor) is the national bird. Chosen by thousands of Danes in 1984 in a national election initiated by Danish Television. This beautiful and majestic bird is the largest bird here in Denmark and very common throughout the country.
