Supplementary Data S1: Species-level maps of distribution of population-level changes in abundance for 461 waterbird species

Supplementary Data S1 Species-level maps of distribution of population-level changes in abundance for 461 waterbird species analysed in this study. In these maps, dots represent 1º ×1º grid cells with change estimates. In each species, population-level declines that are categorised as Critically Endangered based on the International Union for Conservation of Nature (IUCN)’s Red List criterion A2 (≥ 80% past decline over three generations) are shown in red, those categorised as Endangered (≥ 50% past decline over three generations) in dark orange, those categorised as Vulnerable (≥ 30% past decline over three generations) in pale orange, and other (less severe) declines in yellow. Population-level increases are also categorised using the same ranges as the categories for declines. Changes with 95% credible intervals overlapping with zero are shown with small white dots. Species’ non-breeding geographical ranges based on the bird species distribution maps of the world are shaded.
