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.

Golden eagles can be killed by colliding with a number of human-made objects, including wind turbines. USGS research wildlife biologist Todd Katzner describes his studies of golden eagle flight. This research is being done to model flight behavior which might help managers understand how placement of wind turbines might pose significant risks to golden eagles.

Predicting the spatial distribution of wintering golden eagles to inform full annual cycle conservation in western North America
Wildlife conservation strategies focused on one season or population segment may fail to adequately protect populations, especially when a species’ habitat preferences vary among seasons, age-classes, geographic regions, or other factors. Conservation of golden eagles (Aquila chrysaetos) is an example of such a complex scenario, in which the distribution, habitat use, and migratory strategies of t
The geographic extent of bird populations affected by renewable-energy development
Bird populations are declining globally. Wind and solar energy can reduce emissions of fossil fuels that drive anthropogenic climate change, yet renewable-energy production represents a potential threat to bird species. Surveys to assess potential effects at renewable-energy facilities are exclusively local, and the geographic extent encompassed by birds killed at these facilities is largely unkno
