The HPA Effect of Avian Mate Separation and Reunion Behavioral and adrenocortical responses to mate separation and reuinion in the zebra finch is in experiment that was done to establish the endogenous mechanisms governing affiliative behavior in naturally bonded mates. The study was conducted in order to understand both neuroendocrine and behavioral responses to separation and reintroduction of pairs. The overall goal of this study was to provide chemical evidence for “adrenocortical involvement in avian par bonding,” and also “hypothalamic-pituitary adrenal activation,” (108) in response to the stressor of separation. The main neuroendicrine substance that was examined was plasma corticosterone (CORT). Concentrations of CORT were measured after separation of the pairs, and also upon reunion. Elevated and reduced levels, compared to the baseline measurement, were recorded and analyzed. The experiment was separated into four separate parts all having to do with separation and reunion, with certain modifications to ensure that the stressor of specific mate separation was the sole reason for CORT variation. In the first part of the experiment, the correlation between mate separation and plasma CORT levels was tested, with separation of same sex birds as a control. In order to maintain validity, 10 pairs were separated and tested. A blood sample was taken after a
