The Rosybill or Rosybill Pochard (Netta peposaca^[2]) is a duck with a distinctive red bill on males and a slate-colored bill on females. Though classified as a diving duck, this pochard feeds more like a dabbling duck.
The species name peposaca is derived from a Guaraní word for "showy wings", referring to the broad white stripe that is only visible with stretched out wings.
The Rosybill is endemic to South America. It is found in Argentina, central Chile, Paraguay, Uruguay and southern Brazil. The population in southern Argentina migrates northward during the austral winter, reaching Brazil and southern Bolivia. It is a vagrant to the Falkland Islands.^[3]
