Australia races to shield little penguins from H5N1 bird flu

Australia is racing to protect its iconic little penguins from the highly contagious H5N1 avian influenza virus. Thousands of tourists annually visit Phillip Island to witness the tiny seabirds parading ashore and along the beach during evenings in the southern hemisphere's spring and summer. The island houses the world's largest single colony of little penguins, numbering around 40,000.

H5N1, which first breached Australia's landmass in June, has now been detected in a Phillip Island penguin, marking the first infection in the colony by this pathogen. The virus has caused severe disease and death in birds globally. In response, Australian wildlife workers have launched an unprecedented vaccination campaign targeting the wild population of little penguins.

James Todd, the chief biodiversity officer for Victoria, stated that this vaccine program is unprecedented in scale, with no similar vaccination effort carried out in a wild bird population anywhere else in the world. Vaccinating wild populations poses significant challenges, primarily due to the need for two doses of the vaccine administered three to four weeks apart. However, wildlife experts are familiar with the birds' burrows and accustomed to handling them during health checks.

The vaccination teams aim to inoculate about 5,000 little penguins near visitor areas, with the program expected to last several weeks or months rather than days. In light of the urgency, experts suggest one to two weeks might be acceptable. Despite the birds' wild nature, the teams are well-equipped to handle them, using microchips to track those that have received the vaccine.
