Great this morning to see my first Swifts of the spring – about 12 flying high over the Ice Rink area and then later towards the barrage end of the bay but still very high. They were reported at 09:30 by regular Bay birder Gareth Stamp. They had disappeared when we walked back across the barrage. The Grey Wag was near the exit lock of Penarth marina and must have a nest nearby judging by the huge beakful of food. A good number of House Martins were present and I noticed one or two fly up into former nest locations on the marina properties. Sand Martns were about, but there was no activity of note at the old dock.
