OK, I'll confess that I'm not an expert on sea birds. I was down at Portland Bill 30 June 2012 and saw a sea bird I can't identify.
It reminded me of a Gannet in the thin long wings and the body was bright white. However the topside of the wings were completely black. This also went from wing to wing across the top of the body.
In that respect it was like a Greater Black Back Gull.
It was a very windy day and this bird would take a few wing beats, about six or seven, and then glide off to one side for a distance.
I did not pick up any yellow on the bird. If it was a juvenile Gannet I would have expected a patchier colouring. On this bird the colouring was crisp.
I also got the impression that it was at least the size of a Gannet.
Basically I've no idea what it could have been and the wind was so strong I could not make out fine details of it's head.
Thanks,
Andy
