Partial regression plot for baseline corticosterone and hemoglobin concentration in the wedge-billed woodcreeper. Data are presented as unstandardized residuals after controlling for sampling time of day, which best explained baseline corticosterone alongside hemoglobin concentration in AICc model comparison (r 2 = 0.48, F2,14 = 6.389; see Table 1). Log denotes the natural logarithm (to base e)
