The Rosy-billed Pochard, alternatively named Rosybill, or Rosybill PochardNetta peposaca 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 Guarani word for "showy wings", referring to the broad white stripe that is only visible with stretched out wings.*
