|Programs -> Mosquitoes -> West Nile Virus -> Dead Birds and Squirrels
Dead birds and squirrels are often the first indicator that West Nile virus exists in an area. Certain species of birds are very susceptible to West Nile virus and will die quickly after infection, while others can live with the virus. Information on the species and location of infected birds is used to make calculated decisions on mosquito control.
