Project summary
Captive-raised animals translocated to the wild often suffer high mortality; for example, Attwater’s prairie chickens have had a survival rate of only 17-18% post-release in recent years. The focus of many translocation programs is on investing resources to produce more individuals rather than to improve the welfare of released animals. This project seeks to reduce the stress and suffering of released Attwater's prairie chicken by identifying a set of pre- and post-release indicators of welfare to target individuals for management interventions. Pre-release, the coping styles of individual birds will be identified during routine cage transfers and handling. Following release, the fine-scale movements of released birds will be traced using customized data loggers. By investigating the association of pre- and post-release behaviors with the body condition, daily environment changes, and ultimate survival of these individuals, it will be possible to identify which birds from future releases will need special attention to aid their survival. The researchers hypothesize that individuals with a more proactive (“bold”) personality will disperse further post-release and suffer higher mortality rates compared to more reactive individuals.
Why we funded this project
Understanding of associations between coping style/personality and welfare outcomes/challenges could be used to predict at-risk individuals in need of interventions such as supplemental feeding, translocation, or medical treatment. For wildlife rehabilitation or “headstarting” programs, coping style associations could also be used to inform rearing protocols to promote resilient styles that result in improved individual welfare in the wild.
