Terrible conditions when I got there pouring with rain and blowing a gale, I nearly gave it a miss. Glad I didn't ! At the far end of the res'r - a Diver - but with glasses covered in rain as well as the binoculars I couldn't get a firm identification other than it wasn't a Red Throated. Then as it came nearer and the rain eased Bingo - a Great Northern Diver showing the classic peaked head and large bill etc.
Also a Little Grebe on the res'r and another still at Ogden (NK)
The GND was still there this afternoon when we left at 15:30
2 Sparrowhawks nearby and 1 Kestrel
