A gull sitting on the water way off on Burrowes pit that Bob picked up through his scope looked interesting,we had thoughts of Caspian.When it finally flew I managed to follow it for a while with my camera. Although only record shots,the primary tip pattern we both think looks good for the species,the legs look fleshy,rather than yellow (yellow-legged Gull) and the eye through the scope looked dark,any comments would be welcome.
