Issued in 2014, the stamps show a pair of mallards (Anas platyrhynchos) and a pair of northern shovelers (Spatula clypeata or Anas clypeata). The stamps show a male (colourful one) and a female (brown one). I have written about the mallard in the past.

The northern shoveler is a species of migratory dabbling duck that can be found in Europe, Asia, North and Central America, northern South America, the Caribbean and areas of Africa. It feeds on plant material, plankton, small crustaceans and other invertebrates.
