Spearman's correlation coefficients for changes in three parameters of constitutive immune function, the change in fuel stores and total food intake in migrating northern wheatears (O. oenanthe) temporarily caged at a stopover site. (Microbial: microbial killing capacity. *p < 0.05; **0.05 < p < 0.10.)
