With the tides conducive to a feasible post-work gull session, I headed down to Thames Barrier Park after work on Tuesday evening. Unfortunately there weren't too many large gulls present, although lobbing a few loaves in soon drew more in from afar. That said, the increased number by 7 pm, when the tide was almost at its optimum, nonetheless produced just three juvenile Yellow-legged Gulls.
Perhaps the most exciting sighting was a white-ringed juvenile Lesser Black-backed Gull. The bird, 'MU', was ringed as a chick in The Netherlands, although I'm currently waiting for full details. Other than that, it was quiet. A couple of juvenile Great Black-backed Gulls were still begging from their parents and I couldn't see any Meds among the Black-heads.
