Bird flu ravaging Antarctic wildlife, scientist warns

A highly dangerous strain of bird flu is spreading rapidly across Antarctica, raising serious concerns among scientists. A Chilean researcher reported on Tuesday that the observed strain has the potential to be lethal to 100 percent of infected animals.

A Rapidly Spreading Threat

Researchers have been monitoring the spread of bird flu to the Antarctic continent for several years. In April 2024, a team led by Chilean researcher Victor Neira detected a particularly virulent strain in five skuas, a type of polar seabird. Since then, the virus has expanded its reach, affecting a range of species along 900 kilometers (560 miles) of coastline.

Did You Know? Antarctic cormorants and skuas together number around 20,000 individuals, making them particularly vulnerable to outbreaks.

Recent expeditions have confirmed cases in Antarctic cormorants, kelp gulls, Adelie and gentoo penguins, and Antarctic fur seals, according to Neira. He stated that the virus has spread throughout the Antarctic region accessible to scientific study.

A High Mortality Rate

The observed strain is exceptionally dangerous, capable of causing mortality in up to 100 percent of infected birds in a short timeframe. This poses a significant threat to Antarctic wildlife, which often exists in relatively small populations.

Expert Insight: The rapid spread and high mortality rate of this bird flu strain underscore the vulnerability of Antarctic ecosystems to emerging infectious diseases, particularly given the limited capacity for intervention and the potential for devastating impacts on already fragile populations.

This outbreak occurs amidst a global wave of bird flu that has impacted birds and mammals worldwide since 2021, facilitated by bird migration patterns. In 2023, a similar outbreak resulted in the deaths of thousands of Humboldt penguins in Chile.
