- Sample size, estimated risk and a priori risk for each epidemiological functional group in each of the three study sites. “Estimated risk” is the product of AIV prevalence calculated for each site across the 12 sampling sessions at the community level (row “Site community”) and for each EFG and of the proportion of the EFG in the bird community (Table2); n = number of birds sampled; based on results presented in Cumming et al. [17]; “na” indicates that no birds of this group were sampled. “A priori risk” for each EFG was globally calculated by multiplying the relative risk for each functional groups (Table1) and the proportion of each group in the bird community (Table2). Values in italic indicate groups that would require more sampling because of relatively high “a priori risk” or high “estimated risk” combined with small sample size. Values in bold for EFG indicate the highest respective values when sample size is adequate for both “estimated risk” and “a priori risk”.
