The actual ducks ( Anas ) are a genus from the subfamily of the ducks (Anatinae). The mallard is one of the best-known representatives of this genus in Central Europe . The only in the western part of Madagascar occurring Bernie pension that Campbell duck that on only 23 hectares Dent Iceland survived and only on the 370-hectare Laysaninsel living Laysan Duck also belong to this genus and are among the rarest water birds in the world.
features
In most species of this genus, especially if they are widespread in the temperate north, the drakes are significantly different from autumn to spring and have extremely splendid plumage. In the females, on the other hand, the plumage is not that different. Experience from keeping species of the real swimming ducks shows that many species are able to reproduce with one another. However, the progeny are generally sterile.
In contrast to the diving ducks of the genera Netta , Aythya and Bucephala , swimming ducks lie so high in the water that the rump stands out clearly. Swimming ducks only dive when there is danger or dig into the bottom of the water to search for food, which they can reach with their beak without completely detaching from the surface. When flying up, they stand up steeply from the surface of the water with their wings flapping without preparation.
Courtship
Many species show a very conspicuous courtship in the winter months . This begins at a time when the animals are not yet able to reproduce. The courtship regularly lasts until the spring months and includes postures, gestures and movements that are species-specific in their order. The long-term courtship serves to find partners of the same kind.

Numerous duck species originally placed in the genus Anas were assigned to other genera in 2009, as it turned out that Anas in the old composition was not monophyletic . These are:
- Genus Mareca
- North American wigeon ( Mareca americana )
- Sickle duck ( Mareca falcata )
- Amsterdam ( Mareca marecula ), extinct
- Pfeifente ( Mareca Penelope )
- Chiloé Wigeon ( Mareca sibilatrix )

- Cape shoveler ( Spatula smithii )
- Fox Shoveler ( Spatula platalea )
- Puna duck ( Spatula puna )
- Teal duck ( spatula querquedula )
- Versicolorente ( Spatula versicolor )
In Germany, in addition to the Mallard as wintering and then second most common duck in Central Europe teal represented, which, like the Pintail and Wigeon breeds in Northern Europe, broods in the summer with us wintering in Africa teal . However, pulling - - all year that can Shoveler be observed. Known as migrant is the Gadwall .
Etymology and history of research
The first description of the genus Anas was in 1758 by Carl von Linné, who assigned 39 species to it. "Anas, anatis" is the Latin word for "duck".
