Netta peposaca (Rosy-billed Pochard)

Wikipedia Abstract

The rosy-billed pochard, alternatively named rosybill or rosybill pochard (Netta 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 Guaraní word for "showy wings", referring to the broad white stripe that is only visible with stretched out wings.
