Canard huppé Lophonetta specularioides

A distinctive, rather large duck that is common in wetlands, lakes, bogs, slow-moving rivers, and along seacoasts. Sexes look alike: grayish brown overall with bold pale dappling on sides of body, a darker face, and a short bushy crest (often hard to see); bill and legs dark gray. In flight, note the big white panel on the trailing edge of the wing (similar to Flying Steamer-Duck, which is heavier bodied and is rarely seen in flight). Eyes typically reddish in Patagonia and orangish in northern Andes.
