South Somerset RSPB group organised a walk round Ham Wall on 17 May 2014. Here are some images and sounds.
The sounds (all in stereo, mp3 files):-
Reed Warbler (with a Cetti's Warbler at the end)
Garden Warbler.
Blackcap.
View of a Great Egret. Which some of our party were referring to as a "great white" - somewhat alarming when near water!
A Marsh Harrier:-
And then the highlight was a pair of Bitterns flying around together for several minutes:-
