The white-cheeked pintail (Anas bahamensis), also known as the Bahama pintail, Bahama duck, or Galápagos duck is a species of dabbling duck that is patchily distributed throughout South America and the Caribbean. It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under its current scientific name.
The white-cheeked pintail was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the current binomial name Anas bahamensis. Linnaeus based his account on the "Ilathera duck" that had been described and illustrated by the English naturalist Mark Catesby in the first volume of his book The Natural History of Carolina, Florida and the Bahama Islands that was published between 1729 and 1732.

GBIF citizen-science records
It is estimated from how often the White-cheeked Pintail is recorded against all the birds logged in Santa Cruz de la Sierra (32 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.
