A Black Swan

Here's something I've never seen before (picture by Petri Kuhno). So beautiful! And the brief YLE article:

A black swan was sighted this week in Hartola, a town some 200 kilometres north of Helsinki. This is the first time the waterbird has been seen in this part of the country.

Petri Kuhno, the avid bird watcher who spotted the bird, says he believes that the black swan joined a flock of whooper swans (Cygnus cygnus) migrating from central Europe.

The black swan (Cygnus atratus) is a large waterbird which breeds mainly in the southeast and southwest regions of Australia. There are also a few small black swan populations in central European countries.

Black Swans have a mostly black body with the exception of the broad white wing tips which are visible in flight.
