There was no sign first thing of the Cattle Egret. Presumably, the snow and lack of ploughing was the cause (although the bird was seen later).
A lunch time trip to Cley eventually gave me the opportunity to get some pics of the Glaucous Gull. It continues to hold its right wing awkwardly, with some damage showing in flight. Also seen from the car were a Black Brant near Walsey Hills and the Black Swan.
