A bit late posting this, but I nipped down to Cardiff Bay on 19th Apr to see the immature Boonaparte’s Gull that had been found the day before. It was out with the Black-headed Gulls, viewed from Plas Taliesin – Penarth Marina., too far out for decent shots. At the Cardiff end of the barrage there were 2 Rock Pipits on the outer rocks, one of which was singing [never heard that before]. A few showy Greenfinch were near the old dock, where 50+ Sand Martins were busy choosing holes in the walls for nest sites. One obligingly perched on a jutting out twig on my side of the dock, to give a good photo opportunity. One image shows how far away the Bonaparte’s was! – spot the gull!
