Recent activity of interest that hasn’t appeared on here. Sand Martins are inspecting the holes in the wall of the old Channel Dry Dock [past N end of the Cardiff Bay barrage], a male Pied Flycatcher turned up at Cosmeston on Tues 12th, then back to the Bay, a Common Tern yesterday [apparently still present this morning] together with a male Wheatear on the outer Barrage rocks and a White Wagtail.
