Moorhen in a tree. According to the guy I was talking to, the Moorhens have to climb up the branches rather than fly in to the nest!
The Great Broad was fairly quiet, 13 Sand Martins and a singing Lesser Whitethroat were the highlights. Scanning the old workings produced one Shelduck and around 30 Tufted Ducks. Again my timing was off (next day Sandwich and Little Terns seen), but the walk was pleasant and had a good chat with one of the locals.
