Avian Influenza Detected at Año Nuevo State Park

A small number of young northern elephant seals at Año Nuevo State Park recently tested positive for H5N1, also known as bird flu. This is the first detection of H5N1 in California’s marine mammal population.

The risk of H5N1 to the public remains very low. We’re sharing guidance on how to protect yourself, your pets and marine mammals – and how you can help.

Marine Mammal Monday: Sea Otters and San Francisco

Ages: 10-14 years old

  • Species conservation
Virtual Program

Sea otters were once found from Mexico to Alaska, including San Francisco Bay and even Japan. Hunted extensively for their luxurious fur, their population dramatically declined. Now under federal protection, current populations can be found in southern California, Alaska and even Russia. Could this rebounding population call San Francisco Bay home once more?

Sophia Lyon, M.S. and Jane Rudebusch, M.S. join host Laura Gill to share findings from their graduate research during this special Marine Mammal Monday program. Learn about sea otters at the northern extent of their range in California, and discover the potential for migration into areas of their historical range in San Francisco Bay and northern California.
