A pleasant walk across the barrage in the sunshine, with a snack in the Norwegian Church. First checked the beach below Penarth Head for the recent Black Redstart & failed to find it. At the Cardiff inshore end of the barrage, there were 3 Goosander [2f, 1m]. Whatsapp then told me the Black Redstart had been seen, so checked again on the way back. Met another Penarth birder [and GBC member] and we found it on the second concrete groyne across the beach. Pleased to get a lift up the hill back to Penarth centre so thanks Richie.!
