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 Identify New Penguin Species for the First Time in More Than 100 Years
A new species of penguin has been discovered for the first time in 100 years, according to a study. Researchers found evidence that the gentoo penguin actually consists of four different species, and one of them was previously unknown to scientists.

First New Penguin Species in a Century Found on Kerguelen
For most of the last hundred years, biologists have argued about how many kinds of gentoo penguin exist. Some argued for one species with a scatter of subspecies. Others insisted there were four, or five, or six separate lineages. The argument never ended, because the birds themselves would not settle it. They look almost identical, […]
