Why is the Health Unit only collecting dead crows and bluejays?
Other birds can carry West Nile Virus but it is impossible to collect and test all birds. These birds are the most susceptible to the virus and die within 72 hours of becoming infected. The quick demise of bluejays and crows makes them the best and earliest indicator that West Nile Virus is present in a particular area. No birds have tested positive for West Nile Virus in Windsor-Essex County this year, but the Health Unit is encouraging all residents to report dead crows and bluejays.
