The Tanimbar corella (Cacatua goffiniana) also known as Goffin's cockatoo or Goffin's corella, is a species of cockatoo endemic to forests of Yamdena, Larat and Selaru, all islands in the Tanimbar Islands archipelago in Indonesia. The species has been introduced at the Kai Islands, Indonesia, Puerto Rico and Singapore. This species was only formally described in 2004, after it was discovered that the previous formal descriptions pertained to individuals of a different cockatoo species, the Ducorps' or Solomons cockatoo (Cacatua ducorpsii). Tanimbar corellas are the smallest of the white cockatoos. This species is Near Threatened due to deforestation and bird trade. The species breeds well in captivity and there is a large avicultural population.
