While hardly ground-breaking stuff, I was pretty chuffed with two Yellow-legged Gulls among 60-70 large gulls on the Thames between the Fuller's brewery and the Black Lion pub, a few hundred metres to the east. In fact, I had my first - a second-summer - within moments of arriving.

Walking west up to the brewery revealed about 40 further large gulls loafing just west of Chiswick Eyot, including a couple of adult Great Black-backed Gulls. Here I found a juvenile Yellow-legged Gull, which went on to show considerable interest in my bread and showed really well. Sadly I only had a couple of slices left so didn't have much time with it cruising around my head, but I intend to reload on the bread front and head back down at low tide early tomorrow morning.
