Greenland White-fronted Geese at Ynys-hir

This morning 17 Greenland White-fronted Geese showed up for a few minutes on the flooded field beside/behind the Breakwater Hide at Ynys-hir. I also counted 218 Curlew, 6 Red-breasted Merganser, 1 Dunlin and 1 Bar-tailed Godwit. There were 9 or 10 Common Redshank but no trace of the Spotted Redshank I was hoping to see.
