Which migratory birds are most vulnerable to H5 bird flu?

Question

Accepted Answer

H5 Bird Flu Strain Affects Various Migratory Bird Species

The H5 strain of bird flu has been detected in Australia for the first time, confirming its presence on every continent. The highly contagious variant was found in a brown skua, a migratory seabird in remote Western Australia, with suspected positive results also from a giant petrel. This marks a significant development as Australia was previously the sole continent without a confirmed H5 detection.
Key Bird Species Impacted by H5 Strain

The H5 bird flu strain has demonstrated a propensity to affect a range of wild birds, with waterfowl, shorebirds, seabirds, and birds of prey being particularly susceptible. These species, often undertaking long migratory journeys, can facilitate the global spread of the virus. The detection in Australia specifically involved a migratory seabird, underscoring the role of these avian populations in the virus's dissemination.
Global Impact on Avian and Mammalian Populations

Globally, the H5 strain has been responsible for severe illness and high mortality rates in both poultry and wild bird populations. Beyond birds, the virus has also impacted marine mammals, with a recent Australian report detailing the deaths of over 13,000 elephant seal pups on a sub-Antarctic island due to the H5 strain. Detections have also been noted in other animal groups, including cats, goats, alpacas, and pigs, indicating a broader host range.
Australia's Response to the Detection

While the detection is concerning, Australian officials have stated there is currently no evidence of mass mortalities in poultry or wild bird populations within the country. An emergency meeting of animal health and agriculture officials has been convened to formulate a national response strategy aimed at containing the spread of the disease. The government has indicated measures will be taken to manage the situation.
