Bald and golden eagles face many anthropogenic stressors such as wind turbines, lead poisoning, electrocutions, and illegal shootings. Unfortunately, current conservation management plans are not as strong or useful as they could be due to a lack of genetic information about each species. Seeing the need for information, the Iowa Tribe of Oklahoma’s Grey Snow Eagle House reached out to Oklahoma State University (Ronald A. Van Den Bussche laboratory) to partner in developing a genetic research program for bald and golden eagles. Utilizing the generated genetics and genomic data, this project aims to determine conservation units and answer debated questions about bald and golden eagle ecology. Currently, Aviary Director Dr. Megan Judkins is working on this project with the Principle Investigator Dr. Ronald A. Van Den Bussche.
Throughout this project, the research team has collaborated with over 15 non-governmental organizations and 3 government organizations to obtain blood samples from eagles from throughout the United States. These samples have helped us generate 28 bald eagle genomes generated at a 2X coverage, one golden eagle genome generated at an 88X coverage, and a custom genetic SNP chip with ~100,000 genetic markers representing both eagle species. Megan and Ronald are also members in the Western Golden Eagle Landscape Genomics Working group organized by Fish and Wildlife.
