Relationship between exploration speed and corticosterone concentrations in wild great tits. Negative relationship between exploration score (higher numbers indicate a faster exploration of a novel room) and corticosterone concentrations 90 minutes after the onset of a capture-restraint protocol in wild great tits (n=16, partial correlation coefficient from general linear model: r=-0.57, p=0.032). Note that the data depicted here were obtained from the same individuals as those depicted with solid lines in Fig. 1[51].
