Gadwall (Anas srepera)
This is another duck that is more common in winter in Dorset and is very much a fresh water bird. It is usually seen in the company of other ducks, especially Mallard.
They strike me as being a very serene, calm bird. They float regally around surveying the scene and rarely make a fuss or any noise.
This is a duck that seems to have grown in numbers in recent years, I certainly see them more often these days than I once did when I started birding.
