The shelducks are a group of larger 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 different 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. For other uses, see Old World (disambiguation). ...

While the classical shelducks for a group that is obviously monophyletic, the interrelationships of these, the aberrant Common and especially Radjah Shelducks, and the Egyptian Goose were found to be poorly resolved by mtDNA cytochrome b sequence data;^[4] this genus may thus be paraphyletic.
