A second marine mammal in South Australia is suspected to have died from the H5N1 strain of bird flu, according to multiple reports. The development follows an earlier case involving another mammal in the state.

The articles describe the finding as preliminary, with suspicion based on evidence consistent with H5N1 rather than confirmed results in the reporting. All outlets frame the incident in the context of wider animal health concerns linked to outbreaks of bird flu and note the implications for how authorities monitor wildlife and respond to unusual deaths.

While the sources provide the same core information—that a second mammal is suspected—their coverage largely repeats the headline details rather than adding distinct figures, locations, or outcomes. No outlet in the provided material specifies the species, exact site of death, or whether testing has been fully completed at the time of publication.
