humboldt penguin Spheniscus humboldti

Uncommon and local; breeds in colonies along the coast of Peru and Chile, where it nests in underground burrows. The only penguin in most of its range, but some overlap in central Chile with similar Magellanic Penguin of colder southern waters. Adult Humboldt is distinguished by a big pink patch at the base of the bill and a single black breast band. Immature Humboldt is very similar to Magellanic Penguin and is not always safely identified in the field, but immature usually shows big pink bill base recalling adult.
