I spent a few hours at Rainham this morning with Rich and Dante, watching gulls coming off the tip and onto the River Thames in the Coldharbour Point area. A couple of Caspian Gulls, both second-calendar-year birds, were seen, including a particularly impressive bird that showed fairly well on rocks by the point.
Yellow-legged Gulls were as plentiful as ever, with at least 30-35 seen, most of which were juveniles. Despite good turnover from the tip, we didn't see the juvenile seen near the landfill by Dom. There wasn't much else about save the usual Black-tailed Godwits in Aveley Bay.
