Summary of the parameter coefficients for the best model for bird identification.

We used a binomial (link = logit) GLMM with village and respondent nested within village included as random effects (not shown). We investigated the effect of respondent gender, respondent age, and species abundance ((1) common vs rare, (2) rare vs extirpated) and their interactive effects on the ability of people to correctly names species at two levels (overall (group+species levels) and specific (species vs groups levels)). Full model details are given in the online supplementary material Table S2.
