Quite a few people looking through the gull roost at dusk which contained  number of Yellow-legged Gulls. A possible for the Caspian was seen and caused some discussion. I’m sure Amy won’t mind but these are two phone scoped pix she managed to get [Amy Schwartz that is, who many will know from Twitter or SWB Facebook]. Looks much the same as the bird Gareth photo’d initially. Thoughts?
