Migration	β	β 95% CI	pMCMC	h 2	h 2 95% CI	Marg. R 2	Cond. R 2
(a) Latitude (n = 513 species)
Sedentary	0.006	[0.003, 0.009]	<0.001	0.991	[0.976, 0.999]	0.007	0.991

Long distance	<0.001	[−0.004, 0.004]	0.940
(b) Temperature (n = 515 species)
Sedentary	−0.014	[−0.021, −0.008]	<0.001	0.990	[0.974, 0.999]	0.010	0.991

Long distance	−0.002	[−0.012, 0.006]	0.626

β/β 95% CI/β pMCMC = posterior mean regression slope estimates, 95% credible intervals, and pMCMC values for body mass on (a) latitude and (b) temperature, fitted for species with different migratory behaviors. h ²/h ² 95% CI = mean heritability (phylogenetic signal) and 95% credible intervals, marg.R ² = marginal R ², the proportion of variance in the dependent variable explained by the fixed effects, and cond. R ²  = conditional R ², the proportion of variance in the dependent variable explained by both the fixed and random (phylogenetic) effects.
