Dave and I visited the Chingford Reservoirs (King George V and William Girling) today for the monthly Wetland Bird Survey count. Considering the time of year it wasn't surprising to find passage migrants moving through as summer migrants headed south for their wintering areas in Africa, as well as the first winter visitors.
A Northern Wheatear was on the banks of the KGV Reservoir, along with at least half a dozen Yellow Wagtails. More Yellow Wagtails were feeding around the edges of the William Girling Reservoir, as well as quite large numbers of Pied Wagtails, and a few Grey Wagtails - it is likely that some of these two species were also passage migrants, even though both species breed at the reservoirs.
Yellow Wagtails on the banks of the reservoir - the amount of yellow on the underparts can be especially variable at this time of year.
Swallows, and House Martins were also moving through in small numbers.
The wetland species that we had come to survey included 25 Black-necked Grebes and the first two Goldeneye of the winter on the William Girling Reservoir, as well as increasing numbers of Common Teal, and a few Green Sandpipers and Little Egrets.
