Model predictions on the effect of (a) remaining migration distance, (b) air pressure, and (c) flow assistance on departure probabilities of 297 spring migration days. Given are the fitted values (black line), with the 95% CrI in grey. To show the effect of the remaining migration distance, the precipitation was set to 0.6 kg/m2/s, the air pressure to 943 hPa, the flow assistance to 4.0 m/s, and the wind speed to 4.6 m/s, which were the mean values as experienced by the eight birds in spring. To show the effect of air pressure and flow assistance on bird departure probability, the remaining migration distance was set to 6,880 km, with corresponding values as given above
