As Australia braces for the potential arrival of the highly pathogenic avian influenza (HPAI) strain H5N1 this spring, one of the Prom Coast’s most iconic birds is in the firing line.
The H5N1 strain has already wreaked havoc across other continents, affecting over 500 bird and 60 mammal species. The toll is terrible: 40% of Peru’s pelicans, more than 240,000 Peruvian boobies, and 97% of elephant seal pups born in southern Argentina have perished.
Dr. Michelle Wille from the University of Melbourne warns that when H5N1 reaches Australian shores, the consequences could be catastrophic, particularly for the Black Swan, which lacks certain immune-related genes.
Health authorities and wildlife experts, including the South Gippsland Landcare Network, are calling on the public to remain vigilant and informed about what to look for and how to respond.
People are advised to watch for clusters of five or more sick or dead wild birds of any species. Even smaller groups or individual birds showing signs of illness, particularly seabirds, waterbirds, shorebirds, or birds of prey, should raise alarm bells.
Infected live birds may exhibit a range of symptoms, including lack of coordination, twisted necks, inability to stand or fly, difficulty breathing, and swelling around the head, neck, and eyes.
While the risk to human health is generally low, some avian flu strains can cause illness in people. As a precaution, the public is strongly advised to avoid contact with sick or dead birds and their environment. Pet owners should also keep their animals away from affected wildlife.
If a suspected case is encountered, the protocol is clear: avoid contact, record observations and location, and immediately report the incident to the Emergency Animal Disease Hotline on 1800 675 888.
As Australia remains the only continent currently free of H5N1, public awareness and prompt action will be vital in protecting the nation’s unique wildlife. With the anticipated return of migratory birds like the short-tailed shearwater between August and November 2024, the coming months are critical.
The South Gippsland Landcare Network is urging people to watch the Biodiversity Council’s webinar on the topic, which addresses the risks and what we can do right now in preparation for its arrival in Australia. It is available to watch at their website www.biodiversitycouncil.org.au Cara Schultz
