- Populasi
- 15,000–40,000 mature individuals, decreasing
- Habitat
- Forest-lined banks of tropical rivers, damp clearings, wet savannas, wooded islands, and muddy/sandy margins of large freshwater wetlands, mostly in lowlands (to ~500 m, occasionally recorded up to 2,600 m); avoids closed-canopy forest interior
- Fakta menarik
- The Orinoco Goose practices conspecific (intraspecific) brood parasitism: a female will sometimes lay her eggs in the nest of another Orinoco Goose pair rather than her own — parasitized nests average around 19 eggs versus about 7 in unparasitized nests, and tend to have higher hatching success.
