Not having visited for ages, we did a complete circuit of the Cardiff Bay Trail this morning, starting at the Penarth end of the barrage. 100’s of Black-headed Gulls in the bay but nothing exciting with them, but a white-headed Cormorant on the inner barrage structure was a very good candidate for the continental sinensis subspieces. After coffee at Coffi by the dock bridge we were more or less halfway round so decided to carry on. After a take out bacon bap overlooking the wetland reserve, there was a Chiffchaff singing by St David’s Hotel and 4 different Cetti’s Warblers were heard. On into Hamadryad Park and two more Cetti’s sang, and a pair of GC Grebes were attending a recently finished nest. Another Cetti was singing just outside by Clarence Embankment, then a further 3 singing on the other side of R. Taff by Channel View. On the The Marl playing field there were 2 Med Gulls – a 2nd cal yr bird with a yellow ring bearing ALPN (thanks to Gareth Stamp – my pix don’t clearly reveal the letters), and a another bird approaching 2ndS plumage.
