Scientists have identified a new penguin species called the southeastern gentoo penguin (Pygoscelis kerguelensis) living on Kerguelen and Heard Islands in the southern Indian Ocean. This marks the first time a new penguin species has been named since over 100 years ago, following an extensive study by 22 researchers from the US and Chile published last April. The research revealed that gentoo penguins actually consist of four distinct species rather than one, thanks to their consistent feeding habits in isolated areas leading to genetic divergence over hundreds of thousands of years.

Story summary
Scientists have identified a new species of penguin in subantarctic waters, marking the first newly named species of this aquatic bird in over a century. The newly recognized species is called the southeastern gentoo penguin (Pygoscelis kerguelensis) and inhabits Kerguelen and Heard Islands in the southern Indian Ocean. An international team of 22 scientists from the US and Chile published their findings last April in the journal *Communications Biology*. Their study, which included genomic, morphological, and ecological analyses, revealed that gentoo penguins actually consist of four distinct species: northern (P. papua), southern (P. ellsworthi), eastern (P. taeniata), and southeastern gentoo (P. kerguelensis). Rauri Bowie, a curator at UC Berkeley’s Museum of Vertebrate Zoology, noted that the taxonomy of gentoo penguins has been debated for over 100 years due to their similar appearance.

Scientists have discovered a brand-new species of penguin — marking the first newly named species of the aquatic bird in over a century.

Dubbed the southeastern gentoo penguin (Pygoscelis kerguelensis), the bird calls the subantarctic Kerguelen and Heard Islands in the southern Indian Ocean home.

It was formally recognized as a distinct species after an exhaustive genomic, morphological and ecological study led by an international team of researchers.

The southeastern gentoo looks identical to other gentoo penguins, which were grouped as one species for generations.

However, the breakthrough study proves gentoos actually comprise four separate species: the northern gentoo (P. papua), southern gentoo (P. ellsworthi), eastern gentoo (P. taeniata), and southeastern gentoo (P. kerguelensis).

“There’s probably no species of penguin where the taxonomy has been more debated than the gentoo penguin,” said Rauri Bowie, a curator and professor at UC Berkeley’s Museum of Vertebrate Zoology.

Researchers contend that the gentoos’ flexible diet indirectly fueled their evolutionary split.
asserted
diet → contend → split
Because the birds gladly feast on whatever prey is nearby — including fish, krill, squid, and cuttlefish — they stick close to home and nest in the same spots year after year rather than migrating.
asserted
they → feast → year
As a result, isolated island populations developed distinct behavioral and ecological habits that were locked in genetically over time.

Combined with geographical isolation and the ocean barrier of the Antarctic Polar Front, this lifestyle drove the creation of new species over the last 300,000 to 500,000 years, according to the team.
