Hormonal mechanisms and consequences of divorce in the zebra finch

Our paper focused on the experimental divorce of zebra finch pairs has been published in the January volume of the journal Hormones and Behavior. The link to the paper is hereThe paper was led by Ondi Crino and is based on bidivorcerd work at Macquarie together with hormone assays that she did when she moved to Deakin, to take a new position in Kate Buchanan’s group. The main findings in the study were that new pairs that formed after an experimental divorce took longer to lay their clutch, and their offspring had higher levels of stress than those of their counterparts that stayed together. The study helps us to understand why so many birds remain with their partners from one breeding attempt to the next – serial monogamy.
