This group were just to the right of the hide
A Water Rail wandered past, for a few yards then took flight for the reeds
Grey Heron sheltered at the foot of the reed belt
Greenshank, Little Egret, Green Sandpiper, Shoveler, Redshank were also present.
Although I was quite certain that I had seen the Spotted Crake on earlier visits I finally convinced myself on the sighting tonight. The clincher was seeing the relative bill sizes of the Spotted Crake and Water Rail together in the scope.
