The shelducks, most species of which are found in the genus Tadorna (except for the

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)

grasses
and other plants.

They were originally known as "sheldrakes", which remained the most common name until the late 19th century.[2] The word is still sometimes used to refer to a male shelduck and can also occasionally refer to the canvasback (Aythya valisineria) of North America.[3]

Systematics

The genus Tadorna was introduced by the German zoologist Friedrich Boie in 1822.[4][5] The type species is the common shelduck.[5] The genus name comes from the French name Tadorne for the common shelduck.[6] It may originally derive from Celtic roots meaning "pied waterfowl", essentially the same as the English "shelduck".[7] A group of them is called a "dopping," taken from the Harley Manuscript.[8]

The namesake genus of the Tadorninae, Tadorna is very close to the

paraphyletic
.

The Radjah sheduck, formerly placed in the genus Tadorna, is now placed in its own monotypic genus:

Early Pliocene
age makes this rather unlikely.
