If you find a dead bird, particularly a crow, jay, magpie, raven, sparrow, finch, or raptor, please file an online report at westnile.ca.gov or call toll-free 1-877-968-2473 (1-877-WNV-BIRD). Dead bird reports are often the first indication that the virus is active in an area, and this allows the California Department of Public Health (CDPH) to monitor the virus throughout the year.
