South Australia’s endangered sea lion population faces a mounting threat from the H5 bird flu, with four of the marine mammals, including a pup, recently testing positive for the virus, according to SA Environment Minister Emily Bourke. The affected animals were discovered among several dead individuals on the Pages Islands, situated between the South Australian mainland and Kangaroo Island, which serves as a vital breeding ground for the species.
Pages Islands Mortality Event and H5 Bird Flu Spread
The discovery on the Pages Islands follows a separate mass mortality event involving crested terns at the same location, where approximately 900 birds were found dead. According to Minister Bourke, testing on 10 deceased sea lions available from the site confirmed three adults and one pup carried the H5 avian influenza virus.
These latest findings elevate the total number of confirmed H5 bird flu cases in South Australian sea lions to five.
