Field notes
- It is primarily terrestrial and rarely swims, preferring to spend its time walking on sandbars or perching in trees.
- The species exhibits extreme vocal dimorphism; the male produces high-pitched whistles while the female emits a harsh, guttural cackle.
- Unlike many waterfowl, it is a cavity nester, often laying eggs in hollow trees or abandoned large-bird nests high above the ground.
- It is highly territorial during the breeding season, with males aggressively defending stretches of riverbank against intruders.
- While historically placed in the genus Neochen, recent molecular data relocated it to Oressochen, alongside the Andean Goose.
Habitat
Tropical forest edges near large rivers, sandbars, and seasonally flooded savannas.
Range
Orinoco and Amazon basins, extending from Colombia and Venezuela to eastern Bolivia and western Brazil.
