Birduck?

I have never seen a bird/duck like this before and was going to call it birduck until Mr I reliably informed me that it is a Mandarin duck
Wikipedia informs us that
Specimens frequently escape from collections, and in the 20th century a large feral population was established in Great Britain; more recently small numbers have bred in Ireland, concentrated in the parks of Dublin. There are now about 7000 in Britain, and other populations on the European continent, the largest in the region of Berlin.

There you go.
