CORT concentrations of male African stonechats in relation to capture method (control, STI) and breeding stage

	Post-capture CORT	Stress-induced CORT
	Estimates and 95% credible intervals	Estimates and 95% credible intervals
Intercept: Control, mating stage	2.6 [2.2, 3.0]	4.1 [3.8, 4.3]
Capture method (STI, control)	0.7 [0.4, 1.0]	0.3 [0.1, 0.5]
Incubation	−0.5 [−0.9, −0.04]	−0.4 [−0.6, −0.1]
Nestlings	−0.4 [−0.8, 0.06]	−0.3 [−0.6, −0.05]
Fledglings	−0.5 [−0.9, −0.08]	−0.4 [−0.7, −0.2]
Scaled mass index	−0.05 [−0.2, 0.07]	−0.05 [−0.1, 0.03]
Age yearling	−0.2 [−0.6, 0.1]	−0.1 [−0.3, 0.1]
Time of day	0.0002 [−0.0003, 0.0007]	−0.0002 [−0.0005, 0.0002]
Handling time	0.003 [−0.001, 0.008]

Data shown are estimates and 95% Bayesian credible intervals of natural log-transformed CORT concentrations. Estimates are relative to the intercept as reference level, which here is the mating stage of controls. The left column shows the post-capture and the right column stress-induced CORT, each with the corresponding Bayesian mean estimate and its’ credible intervals. Estimates of the cofactors capture method and breeding stages refer to differences from the intercept estimate. When 0 (zero) is not included in the credible intervals there is a detectable effect of this parameter on the dependent variable (shown in bold)
