No, it's not your local boozer or perhaps it is... but in this instance it's an unusual bird sighting!
Black Swans are native to Australia and are the state bird of Western Australia so one to remember for your Black Swan pub quiz.
I wonder if I could hypnotise you....if I write the words 'Black Swan' enough in this blog?

Black Swans were first introduced to Britain accidentally after ornamental birds escaped and you can now find them sharing the same types of habitat as our own native swans.
In Wales they aren't a common site though, so we were delighted when Ralph Hillard sent in these shots from Anglesey, taken on 4 November:

This particular swan was spotted at Cemaes Bay in Anglesey and was happily feeding, swimming, walking and taking short flights with it's white wing tips clearly visible.
Has it escaped from somewhere locally? Or did this individual fly in from further afield...
Thanks to Mike Thompson for passing on the information and photos.
