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.
Region
Southern Andes and Patagonian forests
Typical Environment
Occurs in southern Chile and adjacent Argentina, especially along forested Andean foothills and Patagonian lowlands. Prefers clear, fast-flowing rivers, stream margins, and sheltered forest-lined lakes with abundant riparian vegetation. It uses gravel bars, backwaters, and marshy edges for feeding and loafing. In winter it may shift locally to quieter lakes and estuarine inlets but remains within the same general region.

Also called the spectacled duck, it is the only member of the genus Speculanas and sports a striking white eye-ring and cheek patch. Its glossy bronze-green wing speculum gives the species its common name. It favors fast-flowing forested rivers in southern Chile and Argentina and is often seen in pairs. Though generally quiet and secretive, it forms long-term pair bonds and nests close to water under dense cover.
Temperament
wary and secretive
Flight Pattern
strong flier with rapid, direct wingbeats
Social Behavior
Usually seen in pairs or small family groups and considered largely monogamous. Nests close to water in dense vegetation, bankside cavities, or concealed ground sites. Clutches are guarded by the male nearby while the female incubates; ducklings are precocial and follow parents along streams.
Migratory Pattern
Resident
Song Description
Generally quiet; females give low, hoarse quacks and scolds near the nest. Males produce soft whistles and grunts, especially during courtship and pair contact.
