Scientists identify new penguin species for first time in more than 100 years
Genetic and physical evidence shows gentoo penguins split into four lineages, and the Kerguelen population is the first new species named in over a century.
- An international research team led by the University of Chile and UC Berkeley identified a new gentoo penguin species, Pygoscelis kerguelensis, on the remote Kerguelen Islands in April 2026, marking the first penguin species described in over 100 years.
- For over 100 years, scientists debated whether gentoos comprised one species or multiple subspecies; whole-genome sequencing of 64 penguins across 10 breeding colonies resolved the taxonomic dispute by revealing four distinct evolutionary lineages separated by the Antarctic Polar Front.
- The holotype anchoring P. kerguelensis is a museum skin collected by Robert Hall on December 31, 1897, and held at the American Museum of Natural History, demonstrating how century-old specimens reveal overlooked biodiversity.
- Climate models project three of the four lineages face severe habitat loss by 2050 under a moderate scenario, as researchers describe the current 'Least Concern' IUCN Red List status as a 'statistical artifact' masking decline in isolated populations.
- Professor Rauri Bowie of UC Berkeley stated whole-genome sequencing has "really important conservation value," yet the four-species revision must pass taxonomic committees before current legal instruments can protect the three smaller populations.

Scientists discover first new penguin species in 100 years
Scientists have identified a new species of penguin, the first to be named in more than 100 years. The bird, called the southeastern gentoo penguin (Pygoscelis kerguelensis), lives on the Kerguelen and Heard Islands in the southern Indian Ocean. It was recognized as a separate species after an international team of 22 researchers, led from […] Read the original article here: Scientists discover first new penguin species in 100 years
Remote to the south of the Indian Ocean are the Kerguels. There are also the southeastern donkey penguins at home. Scientists have a theory of how the species developed.
Look-alike, but not the same: Scientists name first new penguin species in over 100 years
A new species of penguin, named Pygoscelis kerguelensis, has been identified in the southern Indian Ocean. Genetic studies revealed that gentoo penguins constitute four separate species instead of one. The southeastern gentoo, previously unknown, has evolved in isolation and adapted to specific environmental conditions. Conservation efforts are now needed as three of the four species face threats from climate change.
In the remote Kerguelen Islands, researchers have discovered a new penguin species, and the new study concludes a scientific debate that has lasted for over a hundred years.
