I had to go back and I am glad I did! Unfortunately, the juvenile Red Necked Phalarope had departed from Redwell Marsh so I headed directly to the pines in the hope that the Arctic Warbler was still present. My attention was drawn to about twenty birders, all looking up into one of the pines, all with an air of enthusiasm. It would have been rude not to have joined them, and I was soon on the elusive and mobile Arctic Warbler. This bird was so frustrating, not staying still fo more than a second, and insisting on keeping branches between it and my camera. I observed the bird before attempting any images. Appended below are a few record shots.
A quick look along the beach produced three Grey Plovers, one of which was still in summer plumage, Black Tailed Godwits, several flybys of Bar Tailed Godwits, Curlew and Sanderling.
