The ruddy-headed goose is a species of waterfowl in tribe Tadornini of subfamily Anserinae. It is found in Argentina, Chile, and the Falkland Islands.
Region
Southern South America
Typical Environment
Breeds in the Falkland Islands and in extreme southern Argentina and Chile (including Tierra del Fuego). Mainland breeders migrate north to winter on open pampas and agricultural lowlands of southern and central Argentina. It favors coastal tussock grasslands, damp meadows, and pastures near freshwater. The species avoids dense forest, preferring open, short-sward feeding areas. On the Falklands it is mostly resident year-round near suitable grasslands and wetlands.

This small sheldgoose has two main populations: a largely resident one in the Falkland Islands and a much-reduced continental population that breeds in Tierra del Fuego and migrates north in winter. Both sexes look similar, unlike several related geese, which can make quick field ID easier. Mainland numbers have fallen sharply due to historical persecution and habitat change, while Falkland birds remain relatively stable.
Temperament
social and active
Flight Pattern
strong flier with direct flight and rapid wingbeats
Social Behavior
Typically forms long-term monogamous pairs and defends small territories during breeding. Nests are on the ground, often hidden in grass tussocks near water, with the male standing guard while the female incubates. Outside the breeding season it gathers in flocks, sometimes mixing with other Chloephaga geese.
Migratory Pattern
Partial migrant
Song Description
Vocalizations are soft, high-pitched whistles and yelps, with males giving clearer whistles and females harsher cackles. Alarm calls are sharper and more insistent, especially when guarding young.
Plumage
Fine gray-and-black barring across the body with a warm ruddy-cinnamon head and neck; wings gray with darker primaries and pale panel; underparts lightly barred to whitish toward the belly.
Diet
Primarily grazes on short grasses, sedges, and herbs, clipping vegetation close to the ground. It also takes seeds and shoots, and may occasionally ingest small invertebrates incidentally while grazing. In agricultural areas it feeds on pasture and crop edges.
Preferred Environment
Open grasslands, damp meadows, and coastal tussock fields near freshwater. In winter it often forages on pastures and low-crop farmland with short swards.
