More Whoopers?

A text from Jonathon B. this morning in reply to todays news;
A friend in Newgale phoned him last night to tell him that there were 18 (eighteen ) swans on Newgale Marsh!
Having sat behind the Duke of E. from 0745 untiil 0845 with no sign of swans, I heard them calling, nine flew in down the valley, in formation at a height. Clearly they roosted elsewhere, talking to Robin, there are a couple of ponds, including one large one up the valley, was this where they roosted?
Are more swans to be found?
When will Newgale dry out?
