Graham Catley has done exceptionally well in obtaining a large selection of photographs of the juvenile High Arctic gull in his region, many more being available on his brilliant 'pewit' birding website.
The bird has been present for over a week now NE of Brigg and east of Elsham and SW of Middleton Road west of the A15 (at approximately TA 843 122). It reappeared today after disappearing over the Easter Bank Holiday weekend. It's identification remains tentative but it does 'tick all of the boxes' with what we have previously accepted as dark Thayer's Gull.
