Possibly the one that’s been hanging out in Dorset, as that wasn’t reported between Thursday and Monday (latest one wasn’t rung, I think previous one was, but not sure of dates down there)

An adult Roseate Tern seen today from the hide at Noah’s Lake. The birds was present on my arrival at 17.00 until it flew off high south at 17.40. Initially somewhat distant over the lake it eventually showed well in flight and perched in the area of the exposed tree stumps 10 o’clock from the hide. Apparently a county mega!
