Extended Data Fig. 2: Multispecies migratory connectivity (exposure) and uncertainty estimates.

Caterpillar plot of all multispecies migratory connectivity estimates (weighted means and non-weighted means for those connections with just single species) and associated credible intervals (CI) for each of the 20 breeding migratory connectivity regions (MCRs; shown as facets) with each nonbreeding MCR (indicated on y-axes). For weighted means, two CIs are shown (80% and 95% CI as thicker and thinner lines, respectively) to differentiate from non-weighted means for single species (only 95% CI shown). Dark blue indicates those means that are significantly above the average connectivity proportion (that is, 95% CI does not overlap 0.071 indicated by dashed black vertical line) across all MCR pairs (n = 921 MCR pairs).
