Great Northern Diver at Oulton Broad

On Saturday 10th December, arriving at the Wherry at Oulton Broad, just watching from the south side, P & J, Andrew, later Chris M and Peter N. The fab Great Northern Diver seen up to 20 metres away constantly diving. It didn't seem to catch any fish, it would then frequently swim right over the Broad towards the Maltings before swimming back again. It always returned to around 20- 30 metres away fairly close but of course I would have liked to seen it even closer.
