Bird-wise the highlight goes to the Great White Egret Ardea alba which was present on Dryham Ings Cell A, before moving on to the Reservoir. The Litte Stint Calidris minuta was still present on the Silt Pond. Several skeins of Pink-footed Goose Anser brachyrhynchus overflow the reserve, both north and south. Ten Curlew Numenius arquata alighted on Island Lake for a clean up session. Finally the hybrid Australian Shelduck Tadorna tadornoides, previously seen in January was back on Reedbed Lake.
