the rudder ducks (Oxyurini) are a generic's group of the Unterfamilie of the ducks (Anatinae) from the family of the duck birds (Anatidae).
The rudder ducks are a quite peculiar group of the duck birds. They differ particularly by the bill from the other ducks. This bill is at the root broadly and highly and curved, the “nail” at the bill point is downward hakenförmig curved in front schaufelförmig upward. In addition the rudder ducks have a wedge-shaped tail from 18 rigid and pointed feathers/springs, which can be spread when swimming radial and be carried nearly perpendicularly from the water raised.
Rudder ducks depart never far from the water and dip very well.
Most kinds belong to the kind Oxyura. Although the rudder ducks have small, curved wings, most kinds are good and fast fliers and expressed migratory birds.
