The first herd of returning Whooper Swans (herd of eight) passed through the LDV on the way back from their Icelandic breeding grounds on the 22nd September. Several passage herds have been noted since and twelve have been present in the usual fields at North Duffield Carrs this week, with more likely to arrive in the coming days and weeks as birds depart Iceland (where they breed in marshes, lakes and small tundra pools). Around 40,000 now winter in the UK with the majority being found in the northern half of the country, with large numbers gathering at the Wildfowl and Wetland Trust centres such as Martin Mere, Caerlaverock and Welney.
Numbers in the LDV usually build up from mid-October and reach between 100-150 birds, with North Duffield Carrs and the fields by Bubwith Bridge being favoured areas. The trumpeting herds passing over the reserve as they head to the Cambridgeshire Fens are a truly welcome sight and sound of autumn. Please do let us know if you see (or hear) any flocks passing over the area.
