We present the mean estimates of β and associated 95% credible interval of the posterior distribution of a logistic mixed effect model based on 65 individuals. Sex, structural richness, and total prey activity density per habitat category and focal area were introduced as explanatory variables, tag deployment as random intercept, and total prey activity density per habitat category and focal area as random slopes
Effects whose credible interval does not include 0 are shown in bold
