A.) What influence did human density (Panel A), crow density (B), and avian species diversity (D) have on the probability of crow decline in a region? B.) From a co-evolutionary perspective, why did the likelihood of crow population declines decrease as WNV spread westward after its introduction in 1999 (see Panel C above)?
