Beautiful day for a full Cardiff Bay Trail circuit, although the 10 km seemed a lot further than when we last did it! Goosander were out in force – I reckon 21 in all – 3f and 1m from the barrage, 2m 1f near the swift tower, 8 [3m and 5f] by the old dock [where the Sand Martins breed], a pair aty Prospect Place and 3f and 1m on the R. Ely by Penarth. There were 70 Cormorant lined up along the inner barrage jetty, 1 Rock Pipit on the barrage rocks and a couple of Redshank and Turnstone by the R. Ely embankment.
