Local Patch birding disturbance x3

On Wednesday 31st December, I started at Mutford Lock, but unfortunately the RT Diver seen by Richard earlier had gone, a child climbing over the railings didn't help. 4 Little Grebes seen and a Redshank seen. Walking along Lake Lothing, I saw 2 well developed Bee Orchid rosettes in the usual place. Checking Ness Point and Hamilton Dock, an Oystercatcher was seen on the finger promontary. Walking along the seawall to Ting Dene static caravan park, I saw a Rock Pipit (unringed) perched on the other side of the seawall but a couple just ahead of me kept flushing it further along 3X it flew back perched up again and then it flew down not to be seen again. As I drew level with the south end of the Ting Dene site, I saw 5 Purple Sandpipers flying in a tight group towards Ness Point but they didn't settle here and they flew back to where I stood and settled on a part of the old seawall before eventually flew up and settled on seaward side of the seawall where they roosted until a dog walker peered over and looked exactly where they were and flushed them as they all flew out to sea.
