Wind support gains and orientation responses of Eleonora’s falcons to sidewinds through Africa's prevailing wind regimes. Black ribbons show the seasonal position of the ITF (cf. red ribbons Fig. 2). The heatmap indicates mean wind support along the GCR to the seasonal destination from each node in the wind data (browns = opposing winds, greens = supportive winds, white = perpendicular winds). We determined whether the tailwinds experienced by falcons along their detours represent (a) gains/losses in wind support compared to what was available along the GCR (reds = losses, blues = gains). b Orientation responses were classified as over-drift (DO, i.e. heading downwind from the GCR), full drift (DF), partial (CP) or full compensatation (CF, i.e. staying on the GCR through sidewinds), overcompensation (CO, i.e. heading upwind the GCR). Cases where falcons stayed on the GCR in absence of sidewinds were not classified (NSW)
