Backyard bird feeding is one of our country’s most popular pastimes. Research reveals about half of Australian households feed wild birds, with many people doing so daily.
However, this practice could act as a superspreader event – where a disease infects an unusually high number of people or animals – of the H5N1 virus. This deadly strain of bird flu has already decimated wild bird and mammal populations worldwide. It is now spreading across Australia, most recently killing more than 1,000 crested terns and a long-nosed fur seal, the first detection in a mainland mammal.
