…We found no significant correlation between body condition and corticosterone levels (Pearson’s r = 0.038, t = 0.443, df = 133, P = 0.659). However, birds with higher corticosterone levels had more positive changes in body mass over the 5 days in captivity (Supplementary Figure S1; Pearson’s r = 0.210, t = 2.468, df = 132, P = 0.015).
