I was meant to be heading to Cley with my group, but a call just after 8am from Andy Brown advised us of a summer plumaged Black-necked Grebe drifting east offshore at Holme, so we headed straight to Gore Point. We noted 2 Velvet Scoter east, 100+ Common Scoter east, also Red-breasted Merganser and 6 Eider. A Great Crested Grebe drifted into view, I was just calling Andy to say we couldn't relocate the BN Grebe, when Ronnie one of my clients, suddenly felt sure he had it and sure enough it was the Black-necked Grebe, in full summer plumage complete with gold "sashes"!! We watched it for a while, before heading down on to the shore to try and get closer views, but we then couldn't relocate it. However, another 200+ Common Scoter passed east and 16 Eider also passed by. Also nice ad male Wheatear in dunes before plantation, 2 Greenshank Lavendar marsh.
