The flying steamer duck (Tachyeres patachonicus), also known as the flying steamer-duck or flying steamerduck, is a species of South American duck in the family Anatidae. The flying steamer duck is one of four steamer ducks, in the genus Tachyeres, which also includes the Fuegian steamer duck (Tachyeres pteneres), the Chubut steamer duck (Tachyeres leucocephalus), and the Falkland steamer duck (Tachyeres brachypterus). The steamer ducks are named for their method of mobility, as the manner in which they use wings and feet to paddle across the water resembles an old-time steam boat. The steamer ducks are members of the Southern Hemisphere shelducks clade Tadorninae. The three flightless species are monophyletic, with the flying steamer ducks splitting off phylogenetically. It is the only steamer duck which can fly, and the only one to occur on inland fresh waters. However, some individual male flying steamer ducks within the species are incapable of flight due to excessive size and wing loadings.
Though they are the smallest of the four Tachyeres species, flying steamer ducks share similar plumage traits with other steamer ducks including... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Flying Steamer-Duck is recorded against all the birds logged in Nahuel Huapi National Park (312 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.
