Some nice photos by Peter  of the hybrid I found this morning but in my scope the only difference  is the noticeably darker mantle; this presumably is the hybrid seen by Alex in Cosmeston.  Also 1 Pochard, 2 Kingfishers, 2 Kestrels and a Stonechat. In Hamadryad Park, a Water Rail and  a Goldcrest  showed in the ‘pond’ and a pair of Cetti’s showed well seen from the viewing circle by the fly-over. 3 Gooseander (2m,1f) were off the Taff Embankment. In Penarth Marina yesterday, there were still 5 Black Redstart (2m,3f) including 1 fem seen in Pierhead  View.
