A deadly strain of bird flu has officially made its way to Antarctica, raising serious alarm among scientists and wildlife advocates. According to New Scientist reporter Michael Le Page, H5N1 bird flu has been confirmed in dead skuas along the Antarctic Peninsula, marking the virus’s first known impact on the frozen continent’s wildlife.
Researchers from the Pontifical Catholic University of Chile, led by Juliana Vianna, discovered 35 dead skuas between November 2024 and January 2025.
Eleven of those birds tested positive for H5N1, the highly pathogenic avian influenza that has been spreading globally in recent years. Worryingly, Vianna said she has now received reports of dead penguins as well, signaling a potentially wider outbreak.
Skuas, known for scavenging and preying on other birds, are likely to spread the virus even further. While the exact extent of the outbreak is still under investigation, the presence of the virus in such a remote and vulnerable ecosystem is troubling.
Penguins, especially Adélie penguins, breed in tightly packed colonies, making them particularly susceptible to rapid virus transmission.
This outbreak follows a devastating trail left by H5N1 across multiple continents. It has already killed thousands of seabirds, sea lions, and even elephant seals across South America and the sub-Antarctic islands.
With the virus now confirmed on the Antarctic continent, experts worry entire bird species—especially those confined to isolated island habitats—could be wiped out.
The virus has traveled thousands of miles and is now moving toward Australia and New Zealand, the last major regions still untouched by H5N1.
If we truly care about protecting animals and preserving fragile ecosystems, it’s time to take a hard look at the root causes of zoonotic outbreaks—many of which are linked to industrial farming and human encroachment.
Choosing a plant-based lifestyle, advocating for better animal protections, and supporting wildlife Conservation efforts are simple but powerful ways to stand up for animals and the planet.
