"Marble-Tail" - seen for a couple of minutes at 10:30 feeding along the near edge of the pool closest to the middle car park. Then flew over to the far corner of the pool where it dropped behind the taller clump of reeds. Longish ivory-coloured tail. In flight, whitish underwing and creamy secondaries were text book for Marbled Duck. Pity about the size, bill and other seemingly inconsistent features!
Pink-footed Goose still present on the same pool.
4 Swift over, plus a female Wheatear along the metal fence in front of the lagoon.
Otherwise, disappointingly quiet.
