Egret in the Ouse

following up the Crane reported by Les Bird yesterday in the Ouse, I checked all the levels from Lewes-southease, with a lengthy detour to Glynde. Highlights were a Common Sandpiper and a Kingfisher on the river Ouse just South of Lewes and 4 Green Sandpipers along Glynde Reach, an excellent count. Some of these showed very well when they were flushed as I walked along. Also along the reach and the surrounding levels were 100+ Teal, 50+ Wigeon, 1000+ Lapwing and 3000+ Starling and a calling Chiffchaff, with 2 Water Rails 'squealing' from a small reedbed just south of Glynde. Also seen atleast 4 Grey Wagtails along the river. However, after spending six and a half hours in the field, The best bird came from the train back to Seaford, as at Southease, I saw a CATTLE EGRET!! It was in a field about 200 metres south of Southease station. I only saw it for about a minute, but I noted its short, dagger-like orange bill, short neck, compact and stocky appearance and a more rounded head than a Little Egret, It also appeared slightly smaller. My year list now stands at 103, with five addititons today, Common Sandpiper, Kingfisher, Green Sandpiper, Chiffchaff and Cattle Egret.
