Bird Flu Kills Dozens of Seal Pups, Closes Seal-Viewing at Año Nuevo
An outbreak of the highly pathogenic avian influenza HPAI H5N1 has killed about 30 elephant seal pups at Año Nuevo State Park in California, prompting the temporary closure of seal-viewing areas through the end of March. Researchers from UC Davis and UC Santa Cruz are intensifying monitoring of the park’s roughly 5,000-seal breeding colony to understand transmission and outcomes, with the virus's source and spread still unknown as wildlife agencies coordinate responses.
