Bird Flu Spreads Across Antarctica, Threatening Vulnerable Wildlife
The highly pathogenic avian influenza (HPAI), commonly known as bird flu, has established itself in Antarctica, raising concerns for the continent’s unique and frequently enough fragile wildlife populations.
the virus was first detected in Antarctica approximately a decade ago, but its spread has accelerated in recent years. As its initial finding, HPAI has been found in multiple native Antarctic species along a 900km stretch of the western coastline, according to Chilean scientist Victor Neira, who leads the research.
“The virus has wholly spread throughout the antarctic region where we have the capacity to go and study,” Neira stated in a recent interview with AFP. [1]
recent expeditions during the Antarctic summer have confirmed cases in at least ten species, including Antarctic cormorants, kelp gulls (previously referred to as Dominican gulls), Adélie and gentoo penguins, and Antarctic fur seals. [1]
While currently, the affected species are listed as “of least concern” for extinction by the International Union for Conservation of nature (IUCN), Neira emphasizes the vulnerability of Antarctic wildlife.“Antarctic species are generally rare on a global scale,” he cautioned. [1]
Populations of Antarctic cormorants and South Polar skuas (previously referred to as labbe antarctique) are estimated at only around 20,000 individuals each. [1] A significant outbreak could have devastating consequences. If the virus continues to evolve and become more virulent, “any species, if severely affected, could end up being threatened with extinction,” Neira warned. [1]
The spread of HPAI in Antarctica is part of a larger global wave. In 2023, bird flu killed approximately 1,300 Humboldt penguins in Chile, representing nearly 10% of that population, according to the National Fisheries Service (Sernapesca). [2] A global outbreak has been impacting millions of wild birds and mammals across the Americas, Asia, and Europe since 2021, largely due to migratory patterns. [3]
The situation in Antarctica is especially worrying due to the limited capacity for intervention and the potential for rapid transmission within densely populated penguin colonies and other wildlife gatherings. Scientists are continuing to monitor the spread of the virus and assess its potential impact on the Antarctic ecosystem.
