Figure 2

Survivorship and conditions experienced upon recruitment estimated from Accelerated Failure Time (AFT) models. In the top plots, peregrines were recruited as yearlings, and in the bottom ones, those were recruited as adults. The left column shows results for lifespan and the right column results for breeding lifespan. Solid-colour lines indicate survivorship after different conditions upon recruitment (‘All’ model predictions for the average observed conditions upon recruitment; ‘Good’ for average rainfall—standard deviation; ‘Bad’ for average rainfall + standard deviation); broken lines are 95% confidence intervals. The black dot-dashed line shows the all condition average value for the other age-group (peregrines recruited as adults in the plots for these recruited as yearlings and vice versa) and was included to ease comparison. Sample size and their distribution by lifespan lengths are detailed in Table 2. The insert in the bottom-left plot shoes the face of a peregrine falcon, our study species.
