Coast avian flu outbreak expands to seals and beaches along California

An avian influenza outbreak (HPAI H5N1) linked to Año Nuevo State Park has spread to other marine mammals and seabirds along California’s coast, with nine more elephant seals testing positive plus a California sea lion and a southern sea otter. Public risk remains very low, but authorities urge people and pets to avoid contact with sick or dead wildlife and report sightings as researchers monitor the situation. The outbreak has caused partial park closures and paused rescue operations, while scientists continue to study transmission and mortality among seals, otters, and birds across the region.

Bird Flu Reaches California’s Northern Elephant Seals

Seven newly weaned northern elephant seal pups at Año Nuevo in California tested positive for highly pathogenic avian influenza (H5N1), marking the first confirmed cases in the state’s elephant seals amid a global surge. Public risk remains low, but authorities are intensifying surveillance, closing seal-viewing areas, and coordinating across agencies to track spread and origins. The outbreak echoes 2023’s severe die-off among southern elephant seals in Argentina and underscores how climate change and migratory shifts can facilitate cross-species transmission, with potential long-term impacts on marine mammal populations and broader ecosystems.

Dane County backyard flock diagnosed with bird flu prompts quarantine

A case of highly pathogenic avian influenza (HPAI) H5N1 was identified in a Dane County backyard poultry flock. The premises were quarantined and the birds depopulated to prevent spread; USDA animal health officials and the Wisconsin DATCP are coordinating the response. Poultry owners are urged to enhance biosecurity and monitor flocks, reporting signs of illness as prompted. The HPAI H5N1 virus continues to circulate in wild and domestic birds across North America since 2021.

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.

New H5N1 Outbreak Reaches California Elephant Seals at Año Nuevo

Researchers confirm H5N1 bird flu in California elephant seals at Año Nuevo, marking the first known infection in the state’s elephant seals; seven of the dead pups tested positive as part of ongoing surveillance that has counted about 30 seal deaths since the outbreak began. Officials say the outbreak likely stems from sick seabirds, with mammal-to-mammal transmission under investigation; the park remains closed and beachgoers are urged to avoid wildlife.

H5N1 bird flu detected in gentoo penguins on Australia’s Heard Island

The gentoo penguin on Heard Island is the first bird on an Australian territory to test positive for H5N1 bird flu, after earlier detections in southern elephant seals; while Australia says it remains free of H5N1 and ongoing detections do not greatly raise immediate risk, experts warn the virus poses a serious threat to wildlife and stress the need for heightened surveillance and preparedness as H5N1 continues to spread across sub-Antarctic islands.

Frozen Birds, Hidden Virus: Why Saving Them Can Be Harmful

The H5N1 avian influenza has become endemic in wild waterfowl, and cold conditions help the virus persist on ice. Public rescue of apparently stranded birds can be counterproductive, as birds may be suffering from infection or stress rather than distress that rescue would fix. Officials urge distancing, reporting dead or ill birds to authorities, and avoiding feeding to prevent crowding that amplifies transmission. The situation has broader implications for poultry losses and surveillance, underscoring that rescuing a single bird can complicate public health and wildlife monitoring.

Antarctic Skua Die-Off Tied to Global Bird Flu Spread

A UC Davis–led study with Erasmus MC confirms that more than 50 Antarctic skuas died during the 2023–24 summers from H5N1 avian influenza, the first documented mass wildlife death linked to the virus in Antarctica. The findings, published in Scientific Reports, underscore the virus’s global reach, raise concerns for penguins and other wildlife, and call for enhanced global surveillance and preventive actions to monitor and curb further spread.

Tamil Nadu Activates Bird Flu Watch After 1,000+ Crow Deaths in Chennai

Avian influenza (H5N1) has resurfaced in Tamil Nadu after 1,000–1,500 crows died around Chennai, triggering intensified state-wide surveillance and biosecurity measures. No human infections have been reported, with authorities coordinating veterinary and public health teams, advising the public to avoid handling dead birds and to ensure poultry is thoroughly cooked. Monitoring is being expanded to poultry farms, hatcheries, live-bird markets, and wetlands to prevent spillover to poultry and people, amid concerns tied to migratory birds and cross-border poultry trade with Kerala.
