The coscoroba swan (Coscoroba coscoroba) is a species of waterfowl in the subfamily Anserinae of the family Anatidae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Uruguay, and the Falkland Islands. It is one of South America's largest species of waterfowl.
The coscoroba swan's placement within the family Anatidae is not fully agreed upon, with a 2014 genetic study positing a phylogenetic relationship between this species and the Cape Barren goose (Cereopsis novaehollandiae). BirdLife International's Handbook of the Birds of the World has adopted this approach and puts the coscoroba swan and Cape Barren goose together in the tribe Cereopsini, which it places as basal to Cygnus and all other geese. However, the South American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy treat the Cape Barren goose as basal to other geese, which themselves precede the coscoroba and other swans in a linear sequence. Even those three systems differ, with the IOC placing the coscoroba before Cygnus and the other two after it in their lists.

Rare
Under 5% of wildlife watchers report a Coscoroba Swan sighting in Península Valdés on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 78th most-seen of the 96 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Coscoroba Swan in Península Valdés on a given day, against under 5% in February–May and August–December, the lowest months. June and July have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Coscoroba Swan sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Coscoroba Swan sightings, Península Valdés ranks 2nd at under 5%. The best odds are in Torres del Paine National Park (Chile, about 10%).
Same family: Anatidae
The closest relatives of the Coscoroba Swan that you can see in Península Valdés (family Anatidae, Ducks, Geese, and Swans) are Crested Duck (about 50%) and Flying Steamer-Duck (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Coscoroba Swan is recorded against all the birds logged in Península Valdés (14 verified sightings from 2019 to 2026), 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.
