Following Caroline's excellent report from the NT section (we met up later at Castlemartin Church to compare notes) it was indeed a good session upstream even if the going on the track was atrocious.
Indeed, I had a staggering count of a flock of 170 dunlin feeding vigorously on the edge nearest me of the flooded meadow. I was grimly counting teal (keeping an eye open for Toby's Green-winged) when I realised there were loads of dunlin skittering about. I've never seen more than single figures on the Corse before and then not this far upstream. I had the scope with me even if keeping myself upright in the mud was a challenge.
It is a tragedy, given how good the upstream section can be, that our vision of 18-19 years ago (when Matt Sutton was my opposite number at CCW) of managing the whole Corse collaboratively as a landscape-scale wetland was never realised. It was endorsed by the National Trust's Nature Conservation Panel in 2012 only to be abandoned shortly after my retirement.
Last of all - a singing chiffchaff. Is this a record?
