First returning wildfowl

A 17:00 visit to Bittern hide turned up the first returning Teal, Bert May had already written it in the log at 13:55. Anyway a female Gadwall and 1 fully grown young was at the far left hand end of the lake, 10 Common Tern + several young still on raft. At BSL 4 adult and 1 fledged Common Tern were circling high and moving E/SE, being that the young bird was fledged this cannot have been local to DP, so presume all were passing thru. Other than that, just 8 Swift overhead and 11 Pied Wagtail on the jetty.
