At last the Jack Snipe at Dinton Pastures.
When I arrived in the hide a lot of birders had the bird but I couldn't find it. A chap put my scope on its location and, finally, when it moved I saw the bird. After a few minutes it started to move about a bit and then it started to bounce. A very weird action for a bird bouncing up and down on flexible legs - it reminded me of a puppeteer controlling his puppets. I'm sure the bird must get leg ache - why does it do it?
No sign of the Bittern on White Swan Lake.
