Bronze-winged Ducks

Bronze-winged Ducks (Speculanas specularis)


The Bronze-winged Ducks (Speculanas specularis), 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 (a genus consisting of only one species). Together they belong to a South American lineage that diverged early from the other dabbling ducks (Johnson and Sorenson, 1999) and may include the steamer ducks.

Distribution / Range

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.


Named after the “bronze” speculum (= distinctive wing patch) , this species is also known as “pato perro” or “dog-duck” after the harsh barking call of the female.

Sexes are alike.

Diet / Feeding:

Ducks feed on larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails, and crabs.

Instead of “teeth,” ducks have serrations (saw-like edges) on their bills that allow them to filter food out of the water.

Captive birds are often fed commercially prepared duck food pellets – if there are insufficient natural resources available to sustain them. As they feed on insects, they are very useful in ridding gardens or lawns of harmful bugs.
