Figure 1 in Lameris et al. (2025): "Wintering centroids (median positions) of individual birds per year, general migration routes and study sites in the Arctic. Dots, squares and diamonds show wintering centroids and inverted triangles show study sites, with in (a) sanderlings breeding at Zackenberg (pink) and red-necked phalaropes breeding at Ammarnäs (light blue) and Slettnes (yellow), (b) Arctic skuas (dots) breeding at Kongsfjorden (red) and Slettnes (yellow), long-tailed skuas (squares) breeding at Ammarnäs (light blue) and rough-legged buzzards breeding at Kolguev Island (green dots), and (c) barnacle geese (green diamonds) and greater white-fronted geese (green dots) breeding on Kolguev Island, barnacle geese breeding in Kongsfjorden (red diamonds), pink-footed geese breeding in Adventdalen (dark blue dots) and tundra swans breeding at the Malozemelskaya tundra (orange dots). Broad migration routes are indicated with dotted lines and colours similar to the study sites and wintering centroids. In (c), barnacle geese breeding on Kolguev Island follow the northern green route while greater white-fronted geese use the entire green route. The dotted line indicates the Arctic circle.
