FIGURE 1.

Interaction of Bergmann's rule with migration. (a) Species’ body mass against breeding latitude midpoint with different slopes fitted for sedentary, short‐distance migrating, and long‐distance migrating species. Mean slopes from posterior distributions are indicated by thick lines, while slopes from the entire posterior distributions are plotted as thinner, semi‐transparent lines. (b) Density plot showing posterior distributions of slope estimates for sedentary, short‐distance migrating, and long‐distance migrating species
