Bird banding and wildlife research involves capturing and handling wild animals. Best practices minimize stress while enabling conservation research that ultimately benefits wildlife.
Wildlife research welfare involves acknowledging that capturing and handling wild animals causes genuine stress and sometimes direct harm, while also recognizing that the conservation data obtained can benefit far more animals in the long run. The ethical framework requires genuine justification for each capture, minimization of handling time and stress, use of the least invasive method adequate for the research question, and monitoring for welfare impacts of tags and markers. The GPS tag revolution has enabled remarkable ecological insights but has also created welfare questions about tag weight, behavior modification, and the stress of repeated capture for battery replacement.
