Had a couple of hours here this afternoon with the following sightings all from the viewpoint (apart from the mallard!)
Red-Crested Pochard. Eclipse male
Green Sandpiper. Colour-ringed, flew in and landed in front of the viewpoint and showed off 2 rings on right ankle and1 ring above the left knee and 1 ring on left ankle. Flew in but then walked into the water then flew off so no colours noted!
