Genus Speculanas
Bronze-winged Duck - The Bronze-winged Duck , also known as the Spectacled Duck, is a dabbling duck and the sole member of its genus Speculanas. It is often placed in Anas with most other dabbling ducks, but its closest relative is either the Crested Duck or the Brazilian Duck, which likewise form monotypic genera. Together they belong to a South American lineage which diverged early from the other dabbling ducks and may include the steamer ducks.
