Fig. 3: Relationships between migratory strategies and life history traits and distribution.

Migratory propensity as a function of mass for a flyers, b swimmers and c walkers; and as a function of d PC1 (fast–slow continuum) and e absolute latitude (n = 1296 species). The solid line corresponds to the median predicted values from the posterior distribution from the Bayesian phylogenetic probit mixed-effects model. Circles represent the proportion of migratory species in each x axis bin. Vertical lines represent the position of each species along the x axis as a function of their migratory strategy.
