The Humboldt penguin is a medium-sized penguin. It resides in South America, along the Pacific coast of Peru, former Bolivia and Chile. Its nearest relatives are the African penguin, the Magellanic penguin and the Galápagos penguin. The Humboldt penguin and the cold water current it swims in are both named after the explorer Alexander von Humboldt. The species is listed as vulnerable by the IUCN with no population recovery plan in place. The current wild population is composed of roughly 23,800 mature individuals and is declining. It is a migrant species.
Region
Pacific coast of western South America
Typical Environment
Occurs along the Humboldt Current from coastal Peru into northern and central Chile, favoring rocky shorelines, offshore islets, and guano islands. Colonies occupy cliffs, boulder fields, and dunes with burrowable substrates. Birds forage mainly in nearshore waters over continental shelves and around upwelling fronts rich in anchovies and sardines. They may disperse more widely at sea outside the breeding period, especially during warm-water events.

Named after naturalist Alexander von Humboldt, this penguin rides the cold, nutrient-rich Humboldt Current along the coasts of Peru and Chile. It nests in burrows and crevices on rocky islands and coasts, often in old guano deposits. Major threats include bycatch in fisheries, guano extraction, disturbance, and food shortages during El Niño events. It is closely related to the African, Magellanic, and Galápagos penguins.

Temperament
social and colonial
Flight Pattern
flightless; powerful underwater flier
Social Behavior
Breeds in colonies, nesting in burrows, crevices, or under vegetation. Pairs are often monogamous across seasons, sharing incubation and chick-rearing duties. Clutch size is typically two eggs, and breeding timing varies with local food availability. Adults show strong site fidelity but may skip breeding in poor years.
Migratory Pattern
Partial migrant
Song Description
Vocalizations include loud, braying calls reminiscent of a donkey, used for mate and territory recognition. Softer honks and growls occur at close range within colonies.
