Yellow-legged Gull: juvenile plumage

I visited the Thames in east London today for a two-hour session with gulls at my regular site. Here are a few images of some of the 11+ Yellow-legged Gulls seen - my interest today was particularly in juveniles, of which there were at least six. I'll let the photos do the talking, but it's interesting to note the subtle variation in plumage (for example, how moult in the first individual is more advanced than in the second).
