The article highlights the popularity of backyard bird feeding in Australia, noting that approximately half of Australian households engage in this activity, often on a daily basis. However, it warns that this seemingly harmless pastime could exacerbate the spread of the H5N1 bird flu virus, which has already caused significant mortality in wild bird and mammal populations globally and is now affecting Australia, recently killing over 1,000 crested terns and a long-nosed fur seal, marking the first detection in a mainland mammal.
The article explains that backyard bird feeding increases the risk of disease transmission by attracting birds of various species to feeding sites in unnatural concentrations, potentially facilitating the spread of pathogens like H5N1. This can create transmission hotspots in residential areas, endangering vulnerable bird species such as the orange-bellied parrot. Moreover, scavenger animals and humans in close contact with infected wildlife face exposure risks, although human infection with H5N1 is rare and typically results in mild symptoms. To mitigate these risks, the article suggests ceasing bird feeding altogether or, if continuing, reducing food quantities, avoiding hand-feeding, and regularly disinfecting feeding equipment with domestic bleach.
