Todd E Katzner
My research interests focus on wildlife conservation ecology and the interaction between wildlife and the role of wildlife in natural systems.
Much of my work is built around utilization of novel technologies and approaches to wildlife ecology. I was part of a team that developed the first non-invasive monitoring scheme for any avian species, I was involved in development of novel high-frequency GPS-GSM telemetry systems for tracking migratory birds, and I developed a network of camera traps to monitor abundance and distribution of terrestrial avian scavengers across eastern North America. Much of my recent funding is focused on evaluating the potential impacts of renewable energy development on conservation-dependent birds.

Conservation plan for golden eagles in eastern North America
The haunting raptor: Yellowstone’s golden eagles
Utilizing high-resolution genetic markers to track population-level exposure of migratory birds to renewable energy development
With new motivation to increase the proportion of energy demands met by zero-carbon sources, there is a greater focus on efforts to assess and mitigate the impacts of renewable energy development on sensitive ecosystems and wildlife, of which birds are of particular interest. One challenge for researchers, due in part to a lack of appropriate tools, has been estimating the effects from such develo
Winter distribution of golden eagles in the Eastern USA
Golden Eagles (Aquila chrysaetos) have a Holarctic distribution, but some details of that overall distribution are poorly understood, including parts of the range in eastern North America. Recent studies in the region suggest that Golden Eagles may be more widely distributed than previously recognized. For species specific conservation efforts to be effective, an understanding of the distribution
