I've seen this bird quite a few times, during the last week or two, but always to distant even for a record shot its been mainly on the flood at Bob Dunn Way, Dartford ..
I first observed this Yellow-legged gull alongside The Jolly Farmers last year and its returned to over-winter in the area again ..
