Sex-specific early life corticosterone stress-coping capacity is linked to mitochondrial content and telomere maintenance

Dataset containing the raw variables used to investigate the links between corticosterone regulation during an acute stressor (initial increase and subsequent return to baseline levels), mitochondrial content and telomere maintenance capacity during the first 30 days of life in a long-lived seabird, the Cocos booby (<i>Sula brewsteri</i>).
