Abstract A strikingly pale colour morph of the Mute Swan Cygnus olor, commonly called the Polish swan, was first described over 170 years ago, yet is still not widely recognised by birdwatchers and no attempt has been made to establish its distribution and abundance in Britain & Ireland.

This shows that Polish swans are concentrated around the eastern and southern coasts of England, and in the Midlands; and that, despite increasing in numbers, they are still scarce birds.
