Shoveler have nested at several localities in the county in the past but in the last twenty years seem to have become confined to three places. During the 1984-88 survey breeding was confirmed at Skomer and Marloes Mere. The 2003-07 survey found confirmed nesting at Skomer and probable breeding at Skokholm and Marloes Mere.
