The Orinoco goose (Neochen jubata) is a species of waterfowl in the tribe Tadornini of subfamily Anserinae. It is found in every mainland South American country except Chile, French Guiana, Suriname, and Uruguay. The Orinoco goose's taxonomy is unsettled. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World (HBW) place it alone in the genus Neochen. However, based on a molecular phylogenetic study published in 2014, the South American Classification Committee of the American Ornithological Society and the Clements taxonomy place it and the Andean goose in the resurrected genus Oressochen. The IOC and HBW place the Andean goose in the genus Chloephaga.
Two fossil relatives have been described from Pleistocene sites in South America, Neochen pugil and N. debilis. The Orinoco goose is monotypic. The Orinoco goose is 61 to 76 cm (24 to 30 in) long. Males weigh about 1.8 kg (4.0 lb) and females about 1.3 kg (2.9 lb). Adult males have an off-white head, neck, and breast with slight buffy streaks on the nape and buffy scalloping on the breast. Their mantle is gray with white scalloping... Wikipedia →

Rare
Under 5% of wildlife watchers report an Orinoco Goose sighting in Medellín on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 229th most-seen of the 244 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Orinoco Goose in Medellín on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Orinoco Goose sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Medellín, in our data
Medellín is the only city on Wallace's Line with enough records to rate Orinoco Goose sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Orinoco Goose is recorded against all the birds logged in Medellín (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
