Description

The aim of the study was to look at the corticosterone increase due to the corticosterone implants. In each brood one or two nestlings were implanted with a corticosterone-implant and one or two nestlings with a placebo-implant (variable Implant). Blood samples were taken just before implantation (day 1), 2 and 20 days after implantation. In total we have 287 measurements of 151 individuals (variable Ring) of 54 broods.
