On Friday, October 16th, the California WNV & Dead Bird Call Center transitioned to internet-only reporting. This marks the end of the WNV dead bird testing season in California for 2026. This year, approximately 9,481 dead birds have been reported, 2,174 have been tested, and 734 birds have tested positive for WNV.
Dead bird reports will still be accepted online through the fall and winter at: https://westnile.ca.gov. CDPH staff will review each internet report and follow up as necessary.
If your agency has questions or would like to continue dead bird testing through the winter, please email: Marie.Cerda@cdph.ca.gov
Thank you for your participation this season!
