Summary: | Species-specific variation in route selection. Posterior means and 95% credible intervals are shown for the species-level random effects (on the slopes) of the INLA model. ;Distribution of values over the used and available steps. These were used for building the step-selection functions. The top row shows the instantaneous values and the bottom row the long-term variances. In the top row, it can be seen that wind support has more variability than delta-T and higher values of wind support are selected by the birds.;Bio-logging data for sea-crossing tracks annotated with wind support and delta-T. Data is pooled for sea-crossing segments during autumn migration of the Oriental honey buzzard (Pernis ptilorhynchus) and the grey-faced buzzard (Butastur indicus) in the East Asian flyways, the osprey (Pandion haliaetus) and the peregrine falcon (Falco peregrinus), in both the African-Eurasian and the American flyways, and the Eleonora's falcon (Falco eleonorae) in the African-Eurasian flyway. For samples of complete tracks, see Fig. 2.;Wind support and delta-T values at the start of each sea-crossing track, grouped by time of day. Most species initiated sea-crossing with positive delta-T and wind support. An overview of wind support and delta-T along the sea-crossing tracks is presented in Fig. S3.
