   Research Interests

I work on research questions to provide information that can be directly applied to management of wildlife, specifically avian species. My research focus includes both conservation of birds and reduction of conflicts between birds and people. With both issues, wildlife managers require information about how animals respond to the environment and wildlife management.
Managers can then use the information on population responses to develop or modify future management. I attempt to provide such information in the form of models that provide projections or predictions about how birds and thus populations may behave in the future. In many cases, I use population models to identify management strategies that may achieve either increases in rare populations or reduction of conflicts in abundant populations.
Most recently, I have worked with two raptor species, Black Vultures and Golden Eagles.
My research on Black Vultures focuses on reducing human-wildlife conflicts at Dutch Gap, Virginia. At this site, Black Vultures have congregated in large numbers (>400 vultures) for many years. While using this site, they have caused damage in the form of roosting and defecating at a power plant and damaging vehicles and boats at a boat ramp by picking at and consuming rubber and other synthetic materials (e.g. windshield wipers, rubber molding, upholstery). At this site, my research has measured population level responses to management actions implemented to dissuade vulture use of the site. I have shown that vultures dispersed from (or reduced fidelity to) the site in response to hazing (use of pyrotechnics and other devices to scare vultures from the site) and culling.
I also participate in research primarily on Golden Eagles, with a focus on reducing risk to eagles from negative effects of renewable energy development. Such risk includes direct mortality due to collisions with wind turbines and indirect effects related to habitat alteration. Our research team (see projects pages at Katznerlab.com) is investigating migration ecology, flight behavior, and habitat use of Golden Eagles in the Eastern and Western United States. Overall, our goal is to provide data and tools that can be used by wildlife managers and developers of renewable energy projects to reduce and mitigate risk to eagles. Such data comes from understanding basic ecology of eagles and responses of eagles to renewable energy development.
