Genus Tadorna
South African Shelduck - This is a 64 cm long bird which breeds in southern Africa, mainly in Namibia and South Africa. In the southern winter, many birds move north-east from the breeding range to favoured moulting grounds, where sizable concentrations occur.
Crested Shelduck - The Crested Shelduck or Korean Crested Shelduck, Tadorna cristata, is a species of bird in the family Anatidae. It is critically endangered and believed by some to be extinct. The male Crested Shelduck has a greenish-black crown, breast, primaries, and tail, while the rest of its face, chin, and throat are brownish black. The male's belly, undertail coverts, and flanks are a dark grey with black striations. The upper wing coverts are white, while its speculum is an iridescent green. The female has a white eye ring, black crest, white face, chin, throat, neck, and uppers wing coverts and a dark brown body with white striations. Both sexes also have a distinctive green tuft of feathers protruding from the head.
Ruddy shelduck - The Ruddy Shelduck, Tadorna ferruginea, is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae. In India it is known as the Brahminy Duck.
Radjah Shelduck - Both the male and female of the species are mostly white, with dark wingtips and a distinctive "collar" of dark feathers. Seen from above in flight, the birds have green bands on the tops of their wings. The female has a harsh rattle and the male has a breathy, sore-throat whistle.
Common shelduck - The Common Shelduck is a widespread and common duck of the Genus Tadorna. Fossil bones from Dorkovo described as Balcanas pliocaenica may actually belong to this species. More likely, they are an extinct species of Tadorna due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2-3 million years later (Late Pliocene/Early Pleistocene.
Australian Shelduck - This is a bird which breeds in southern Australia and Tasmania. In the southern winter, many birds move further north than the breeding range. As with other shelducks, this species has favoured moulting grounds, such as Lake George, NSW, where sizeable concentrations occur.
Paradise Shelduck - The Paradise Shelducks usually live as pairs, grazing on grass and weeds, and will raid crops, particularly when molting.
