In recent weeks, beachgoers across California have reported finding sick or deceased seabirds along the beaches, which has sparked concern over the health of our ocean and our wildlife.
Research conducted by the California Department of Fish and Wildlife and other research institutions has found that while avian influenza is impacting marine mammals in the central and northern coasts, it is not the primary driver of this seabird mortality event. Instead, starvation due to changing ocean conditions is likely the leading cause.
Surfrider chapters host events along the coast nearly every weekend, meaning we can serve as consistent eyes and ears on the shoreline, documenting changes, identifying emerging issues early, and mobilizing our community to respond in the following ways:
⚠️ Report stranded seabirds by calling your local wildlife rehabilitation facility.
⚠️ Report dead seabirds to CDFW’s Wildlife Health Laboratory using the mortality reporting form, which helps biologists monitor the event. Please include photos if possible.
⚠️ Report marine mammals: To report a dead, injured or stranded marine mammal in California, call the NOAA Fisheries West Coast Region Stranding Hotline: (866) 767-6114. Information on species and regional stranding contacts may be found on the NOAA Fisheries website.
⚠️ Please DO NOT touch or collect dead, sick, or injured animals, and please DO keep your pets away from them.
