^*Numbers represent log₁₀ plaque-forming units/mL of serum titers determined by plaque assay on Vero cells.

^†Numbers in parentheses represent numbers of American crows inoculated.

^‡Mean day of death is represented in days post-inoculation.

^§Numbers represent the total number of decedent American crows used for the calculation of mean day of death.
