A fairly common dabbling duck found throughout the year, the gadwall is only a little smaller than a Mallard. It nests in small numbers in the UK, on freshwater lakes with lots of vegetation, but can be seen in large numbers in winter at reservoirs, lakes, flooded gravel pits and coastal wetlands. This image of a female Gadwall was taken at RSPB Rainham where large flocks were present.
