WNV Dead Bird Hotline Update

Apr 16, 2018

The West Nile virus and Dead Bird Hotline is staffed with live operators from 8AM to 4:30PM, Monday through Friday (later we will also be staffed on Sundays). Call the hotline at 1-877-WNV-BIRD to report a dead bird. Or fill out an online report form here:

Report a Dead Bird

Hotline operators will determine if the bird meets criteria for pickup and testing They will arrange for suitable dead birds to be picked up by a local vector control or public health agency for West Nile virus testing. Dead bird reports are very important because they are usually the first indication that the virus is active in an area, and this allows CDPH and local agencies to monitor the virus and implement control measures throughout the year.

Thank you for your report!
