I arrived at Rishton with about 30 minutes of daylight remaining. The white-fronts were all in clear view on the far side of the reservoir with the Canada goose. flock. There were six eurasion white-fronts (two adults and four juveniles) and two Greenland race birds which are likely to be the two present before Christmas, (and which I failed to see one Saturday morning). It was very educational to see both races together; the Greenland race clearly darker than the eurasians with the bill differences clearly apparent, even with the dull and fading light. Of note, the adult eurasions frequently showed aggression to the Greenlands if they came too close, but not to any of the Canadas.
Some photos of the gulls and guillemot below. The Little Gull was rather distant but I've included it because is nicely shows the upperwing comparison with the juvenile Kittiwake; the Little Gull showing a dark secondary wing bar and the Kittwake showing umarked white secondaries.
