Also known as Shelducks
The shelducks, most species of which are found in the genus Tadorna (except for the Radjah shelduck, which is now found in its own monotypic genus Radjah), are a group of large birds in the Tadornini tribe of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.

Vogels Tadorna is een geslacht van vogels uit de familie eenden, ganzen en zwanen (Anatidae). Het geslacht telt 6 soorten.[1] Het is een groep van grotere watervogels die ook vaak op het land te vinden zijn, met soorten die afkomstig zijn uit de Oude Wereld en Australië. Qua morfologie zitten ze in feite ergens tussen eenden en ganzen. Het vrouwtje is doorgaans wat lichter gekleurd dan het mannetje bij deze soorten. Hun dieet bestaat uit kleine ongewervelden, grassen en watervegetatie. Soorten Tadorna cana (Grijskopcasarca) Tadorna ferruginea (Casarca) Tadorna radjah (Radjah-eend) Tadorna tadorna (Bergeend) Tadorna tadornoides (Australische bergeend) Tadorna variegata (Paradijscasarca) † Tadorna cristata (Kuifcasarca) (Kuroda, 1917) Bronnen, noten en/of referenties ↑ Gill, F., Wright, M. & Donsker, D.

The shelducks, most species of which are found in the genus Tadorna (except for the Radjah shelduck, which is now found in its own monotypic genus Radjah), are a group of large birds in the Tadornini tribe of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.
==Biology== Shelducks are a group of large, often semi-terrestrial waterfowl, which can be seen as intermediate between geese (Anserinae) and ducks. They are mid-sized (some 50–60 cm) Old World waterfowl. The sexes are colored slightly differently in most species, and all have a characteristic upperwing coloration in flight: the tertiary remiges form a green speculum, the secondaries and primaries are black, and the coverts (forewing) are white. Their diet consists of small shore animals (winkles, crabs etc.) as well as grasses and other plants.
