James Emerson
Norwich Birder
Now relocated on the River Yare in the Strumpshaw area. There is a precedent for this, the 2009/10 bird started off on the river near Buckenham and lingered in that area for three weeks if memory serves, before working its way to Whitlingham where it stayed for a couple of months.
per Birdguides the Rockland Broad Great Northern Diver flew off towards Norwich at 11h15 this morning. Worth checking Whitlingham?
