The Humboldt Penguin (Spheniscus humboldti) (also termed 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 the cold water current it swims in, which is itself named after Alexander von Humboldt, an explorer.
Humboldt Penguins are medium-sized penguins, growing to 65-70 cm (26-28 in) long and a weight of 3.6-5.9 kg (8-13 lbs). They have a black head with a white border running from behind the eye, around the black ear-coverts and chin, to join on the throat. They have blackish-grey upperparts and whitish underparts, with a black breast-band extending down the flanks to the thigh. They have a fleshy-pink base to the bill. Juveniles have dark heads and no breast-band. They have spines on their tongue which they use to hold their prey.
