This morning there were 3 Common Sandpipers along the R. Ely embankment by Penarth Marina, plus 15 Turnstones. A Raven was sitting around on equipment in the environment building yard at the N end of the barrage and 2 Common Whitethroats were singing in the scrub by the path past the Swift tower. The feeder dock had about 40 Sand Martins investigating the nest holes.
