Examples of "backed_duck_thalassornis"
The white-backed duck ("Thalassornis leuconotus") is a waterbird of the family Anatidae. It is distinct from all other ducks, but most closely related to the whistling ducks in the subfamily Dendrocygninae, though also showing some similarities to the stiff-tailed ducks in the subfamily Oxyurinae. It is the only member of the genus "Thalassornis".
Eight species of whistling duck are currently recognized in the genus "Dendrocygna". However, Johnsgard considers the white-backed duck ("Thalassornis leuconotus") from Africa and Madagascar to be distinct ninth species, a view first proposed in 1960 and initially supported by behavioral similarities. Later, similarities in anatomy, duckling vocalizations, and feather proteins gave additional support. Molecular analysis in 2009 also suggested that the white-backed duck was nested within the whistling duck clade. In addition to the extant species, subfossil remains of an extinct, undescribed species have been found on Aitutaki of the Cook Islands.
Altogether, however, the only thing that seems clear is that the musk ducks probably are not part of the stiff-tailed ducks in the strict sense, but rather represent a not-too-distantly related lineage that is highly convergent as regards their hind limb anatomy. These two are probably part of a very ancient radiation of Gondwanan (often Australian) waterfowl, including such forms as the Cape Barren goose ("Cereopsis"), the coscoroba swan ("Coscoroba"), the freckled duck ("Stictonetta") which once was placed in the Oxyurinae, or the pygmy geese ("Nettapus"), but the exact relationships between these lineages remains unresolved. For example, the African white-backed duck ("Thalassornis") also shows some similarities to "Oxyura", but again, this may be yet another case of convergent evolution.
