The feeder dock in Cardiff Bay just before Porth Teigr is now busy with Sand Martins claiming holes in the dock wall. The photos were taken on Sat 20th, when there was also a House Sparrow pretending to be a new species – Brown Wallcreeper! There were also a good number of House Martins inspecting nest sites at Penarth Marina, although it was disappointing to see that the residents in an apartment that faces the lock control room, had obviously hacked off several HM nests from last year from their roof facias. Sadly no Swifts were seen at all.
