First visit yesterday to the barrage since lockdown started. Managed a shot of a pair of House Martins doing some refurbishment on a house in Penarth Marina. By the water taxi embarcation jetty a Mute Swan with 6 cygnets. At the Cardiff end of the barrage a Common Whitethroat was singing at the top of a tree and a rather tatty looking male Blackbird was on one of the old mooring posts. A Cetti’s Warbler was singing just before the old Roath Dock. Plenty of Sand Martins nesting in the holes of Roath Dock. No sign of any Swifts at all.

I wasn’t expecting to be able to do my annual survbey of House Martins around Cardiff Bay but maybe now it will be possible. Just about 5m from my house to Tesco Penarth I think. Did you take house number of those ones?
Sorry Paul, no. I was walking dog with Anne so not really concentrating. It was one of the houses facing the bay.
