From: The start of migration correlates with arrival timing, and the total speed of migration increases with migration distance in migratory songbirds: a cross-continental analysis

Fig. 4

Model estimates of the between-species effect of the total migration distance on the total speed of migration. a Total speed of migration in spring (180 individuals of 22 species) and b in autumn (245/24) as a function of the total migration distance. The predicted between-species effect of the total migration distance on the total speed of migration is shown. The fitted values (black solid lines) with the 95% credible interval (grey polygon) are given. The within-species effects are visualized with species-specific regression lines. Raw data are given in species-specific colours (Table 1). The axes show the log10 transformed values of the corresponding variables
