The top-supported model explaining individual variation in stress-induced corticosterone amongst adult Red Crossbills was that with relative telomere length. Though there was an effect of context (pre- or post-food restriction) on adult stress-induced corticosterone, the relationship with telomere length was independent of the context. Points display individual values, line represent the line of best fit, and inset graph displays slope estimate and 95% confidence intervals generated by the model summarized in Supplementary Table 4D. The gray slope value was estimated without the inclusion of the outlier point, which was collected post-food restriction. See Table 2B for the associated AICc table.
