If you see a bird, particularly a crow or magpie, lacking signs of trauma that has been dead for less than 24 hours, please call 1-877-WNV-BIRD (1-877-968-2473) or report it online here. Crows and magpies are particularly susceptible to the disease, so they make excellent early warning sentinels for virus activity in our area.
