Hooded Merganser on the estuary

Another early start at 8.30am on Sunday 18th November, the Merganser was nowhere to be seen on the river but the fine male Hooded Merganser was seen looking due east from the bridge and was swimming around the area by the line of submerged posts. It swam round and came a little closer just south of where I was looking before it flew out to the water by the submerged sticks again. Also c300 Black- tailed Godwit and 188 Avocets seen too.
