GBBGull P:26F was originally ringed in June 2021, first sighting came from Port en Bressin in Calvados from Gilbert Vimard during August 2022.

On the 13th February we received a second sighting of this GBBGull from Perelle Beach Guernsey from Wayne Turner.

Wayne noticed the strange colouring on the bill. A search of the internet shows it is likely to be a result of diet that this coloration has occurred.
