Ivlev's electivity index is calculated for each species using the proportion of individuals ingested (used) and the proportion of animals captured in the field (available); p-values indicate the statistical significance of differences between observed and expected small mammal consumption (Fisher's exact Chi-square test).

^a species not captured in the field and not found in feces

^b species not captured in the field, but found in feces
