1000+ Dunlin and Ringed plovers roosting on the cobble area by Ynyslas saltmarsh this morning (about 50:50 split). With them were 2 Curlew Sandpipers, c.10 Sanderling, 8 Knot and a juvenile Ruff (very small individual, presumably a female).
A couple of dog walkers who walked through the middle of them and flushed the lot were completely unrepentant when the results of their behaviour were politely pointed out to them. (I suggest it's still worth doing so though).
A walk up to Glandwr Pools produced an adult male Ruff, 2 Black-tailed Godwits and c. 15 Teal.
