After reports of a black-throated diver and scaup on the river Clwyd I paid a visit this afternoon. No sign of the diver but the male scaup was still present near the sunken boat. This is probably the same bird that's commuting between here and Rhyl Brickworks pond. On the way back found an adult winter Med gull in among the black-headed gulls and common gulls in field near the pylons with 160 golden plover also there and scores of fieldfares and redwings.
