I began feeling a little better so spent an hour by the River. Luck would have it there was a new first winter Caspian Gull at the O2.
A slightly murky and quite small bird, although aggressive albatross posture and long call were adopted a couple of times. Plain greater coverts with the pale tips giving a strong wing bar in this individual, and a hint of one across the median coverts too. This bird is the 5th first winter I’ve seen in the area since September and contributes to 7 different individuals seen between the O2 and Thames Barrier Park this season. (Click on images to enlarge)
