Oressochen jubatus[2][3] The Orinoco goose (Neochen jubata) is a Near Threatened species of waterfowl in the tribe Tadornini of subfamily Anserinae.

[4][5] It is found in every mainland South American country except Chile, French Guiana, Suriname, and Uruguay.

Adult females have a similar pattern as the males but have a drab wash on their crown and nape, less orange on the flanks, and darker scalloping on the sides of the belly.

Though the IUCN range map includes French Guiana, Suriname, and Paraguay, the South American Classification Committee of the American Ornithological Society has no records in the first two countries and records only as a vagrant in Paraguay.

Toxoplasma gondii and Neospora caninum are both apicomplexan parasites that infect various animals and cause severe disease.

Orinoco goose meat is eaten by people in Bolivia and Brazil, potentially leading to human infection.

[11] The Orinoco goose is herbivorous and feeds mainly on leaves and seed heads, especially those of grasses.

[8] Orinoco geese form strong year-round pair bonds and are intensely territorial during the breeding season.

During the breeding season males make "a high whistle and guttural honks" and females "a loud cackle".

It has a large range but its estimated population of 10,000 to 25,000 mature individuals is decreasing "at a slow to moderate rate".

The major cause of the decline appears to be hunting because populations on unhunted protected areas are stable.
