The Magellanic penguin (Spheniscus magellanicus) is a South American penguin, breeding in coastal Argentina, Chile and the Falkland Islands, with some migrating to Brazil. It is the most numerous of the Spheniscus penguins. Its nearest relatives are the African Penguin, the Humboldt Penguin and the Galapagos Penguin. The main threat to this species is oil pollution which kills more than 20,000 adults and 22,000 juveniles every year off the coast of Argentina.
