Got down to the barrage for first time in a while and eventually found the Red-throated Diver that was found a coupe of days ago. It was quite distant towards the Cardiff end off the dock area by the gas storage tanks. After coffee by Porth Teigr it fortunately came a little closer on the walk back and I Iucked in on some wing stretch shots. There was also a very confiding female Pied Wag on a wall by the sluices.
