The gentoo penguin ( JEN-too) (Pygoscelis papua) is a species complex in the genus Pygoscelis, most closely related to the Adélie penguin (P. adeliae) and the Chinstrap penguin (P. antarcticus). The earliest scientific description was made in 1781 by Johann Reinhold Forster with a type locality in the Falkland Islands. The species calls in a variety of ways, but the most frequently heard is a loud, trumpeting call, emitted with the head thrown back. A new gentoo penguin species, Pygoscelis kerguelensis sp. nov., was discovered in April 2026 in the Kerguelen Islands.
The application of "gentoo" to the penguin is unclear. Gentoo was an Anglo-Indian term to distinguish Hindus from Muslims. The English term may have originated from the Portuguese gentio ("pagan, gentile"). Some speculate that the white patch on the bird's head was thought to resemble a turban.
It may also be a variation of another name for this bird, "Johnny penguin", with Johnny being the English counterpart of the Spanish nickname Juanito and sounding vaguely like gentoo. The Johnny rook, a predator, is likely named after the Johnny penguin.
The specific name papua is a misnomer; in the original description...
