Named after the "bronze" speculum this species is also known as "pato perro" or "dog-duck" after the harsh barking call of the female.
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.
As noted by Johnsgard (2010): "Most observers agree that heavily forested rivers that are relatively swift-flowing are the preferred habitat of this species, although they also occur on slow-moving rivers and on pools or ponds of the adjoining forest areas.
They are said to consume both vegetable and animal materials, and have been observed eating small snails that abound on stony shingle beaches.
In captivity at least the birds seem to spend a good deal of time on land and have not been observed diving for food.
