V v wet this morning but there was a Med Gull on the W lake posts. Haven’t seen one in the park fo quite a while. Difficult to see detail but could have been AdW or poss late 2ndS [thought I could make out 2 v small black spots in the primaries]. Graham Smith had a Med/B-h Gull hybrid on Penarth beach recently but I don’t think this was it. Bill looked fully Med Gull weight and size was full Med Gull.
