On 25 Oct 2023 the Argentina government veterinary service SENASA
confirmed HPAI H5N1 in elephant seal pups at the sites of mass
mortalities. The loss of newborns is estimated to be near total, and
the fate of reproductive females is unknown because they seem to have
abandoned the beaches prematurely.
Confirmed positive kelp gulls (Larus dominicanus) and South American
terns (Sterna hirundinacea) were found at the same sites.
