Figure 3

The change in various movement characteristics of vultures as a function of time since the last feeding event (the days within a FDP). The lines represent the best fitting model among a hump-shaped model (second-order polynomial, grey solid line), a linear response model (first-order polynomial; green dash-dotted line) and a lack of response model (grey dashed line on the mean value). Models were ranked according to AIC_c. Travel distance (a), maximal displacement (b) and flight elevation (d) showed similar hump-shaped trends, increasing for the first five days and decreasing afterward. FDP length had no clear effect on flight straightness (c), proportion of active days (e) and roost departure time (f). Error bars are S.E. between individual mean values.
