acv560-sup-001-S3.docx33K Material S3. Occurrence probabilities for all observed bird species averaged over all plots in each region and year from posterior estimates of the multi-species model. Note that values of posterior mode estimates provide only an estimate of the magnitude of regional prevalence but not the uncertainty in these estimates; for simplicity, however, we did not include the credible intervals that reflect uncertainty in this table.
