Crested Duck and Bronze-winged Duck: Iridescent purple-bronze, edged white.

The Bronze-winged Duck (Speculanas specularis) also known as the Spectacled Duck, is a dabbling duck and the sole member of its genus Speculanas.

The Bronze-winged Duck lives among forested rivers and fast-flowing streams on the lower slopes of the South American Andes, in central and southern Chile and adjacent parts of Argentina.

It was formerly considered a "perching duck", but more recent analyses indicate that it belongs to a clade of South American dabbling ducks which also includes the Crested Duck, the Bronze-winged Duck, and possibly the steamer ducks.

However, mtDNA sequence analyses of the cytochrome b and NADH dehydrogenase subunit 2 genes indicate that Tachyeres rather belongs into a distinct clade of aberrant South American dabbling ducks, which also includes the Brazilian, the Crested, and the Bronze-winged Ducks.
