Order: Anseriformes
Family: Anatidae
The Argentine Ruddy Duck is a small, compact diving duck native to southern South America, including the wetlands and lakes of Patagonia. Males are easily recognized by their chestnut bodies, bright blue bills, and stiff, spiky tails, while females are more subdued in color with mottled brown plumage and a dark bill. Adapted for an aquatic lifestyle, these ducks have legs set far back on their bodies, making them excellent swimmers and divers but rather awkward on land. They are generally quiet, but males become more vocal during the breeding season, producing a series of pops and whistles as part of their courtship rituals. The species is mostly resident, though some local movements occur in response to water levels. Their unique appearance and behaviors make them a favorite among birdwatchers in Patagonia.
Habitat
Prefers shallow lakes, ponds, marshes, and slow-moving rivers with abundant aquatic vegetation throughout Patagonia.
Foraging
Feeds mainly by diving underwater for seeds, roots, and aquatic invertebrates.
