Stopped off at Furnace on the way home from work to see if anything had dropped in and was greeted by the sight of a couple of Swallows over the lake. A pair of Mandarins flew in just as a Sparrowhawk shot across, low to the water.I spoke to an angler( Andy) who said that earlier he had seen about 25 Swallows flying around in the middle of a downpour and that he'd also seen 70-80 Fieldfares.Other than that it was just the usual suspects.The first Mallard ducklings appeared with 15 trailing behind their mother.
