The Humboldt Penguin (Spheniscus humboldti) (aka Peruvian Penguin, or Patranca) is a South American penguin, breeding in coastal Peru and Chile. Its nearest relatives are the African Penguin, the Magellanic Penguin and the Galápagos Penguin. The penguin is named after Alexander von Humboldt, a naturalist and explorer who first described the animal to the scientific community. Humboldt Penguins nest on islands and rocky coasts, burrowing holes in guano and sometimes using scrapes or caves.
