Cairina moschata
The white-winged duck or white-winged wood duck ("Asarcornis scutulata") is a large species of duck, formerly placed in the genus "Cairina" with the Muscovy duck ("Cairina moschata") and allied with the dabbling ducks. However, mtDNA cytochrome "b" and NADH dehydrogenase subunit 2 sequence analysis indicate that the anatomical similarity to the Muscovy duck is deceiving and that the species is appropriately placed in a monotypic genus, as "Asarcornis scutulata", which is evolutionarily closer to the redhead ("Aythya americana", one of the diving ducks).
