On a visit to Ynyslas this morning I sat by the brick hut on the edge of the golf course and watched hundreds and hundreds of Manx Shearwaters over and on the water in front of me. Also, I think I found Harry's Eider - there were 6 or 7 of them bobbing up and down on the sea.
There were Gannets, not in large numbers, and during the hour or so I spent watching about 20 Swallows flew north.
