I am interested in the behavioral ecology, physiology, conservation, and management of birds. Much of my research focuses on birds of prey as part of our Raptor Biology program, although my students and I also pursue research on other species. I have current projects related to the behavioral ecology and conservation of burrowing owls, roadway mortality of barn owls, population viability analysis of barn owls, post-fledging behavior of western screech-owls, the role of burrowing owls in plague ecology, host-parasite relationships in burrowing owls, and ecotoxicology of ferruginous hawks.

Graduate Projects

Students interested in graduate projects leading to either an MS in Raptor Biology or PhD in Ecology, Evolution, and Behavior (EEB) can contact me directly, although I am not currently recruiting students.


I am not currently recruiting for graduate students. However, new project opportunities open up all the time, so please do not hesitate to contact me to inquire.


I also serve as Principal Investigator and Project Director for a Research Experiences for Undergraduates (REU) Site in Raptor Research at Boise State University. This REU site is funded by the National Science Foundation, and Boise State University partners with the Raptor Research Center, Intermountain Bird Observatory, College of Western Idaho, The Peregrine Fund, Inc., and the Morley Nelson Snake River Birds of Prey National Conservation Area to provide opportunities for undergraduate research focused on birds of prey. Please see our program web site for further information REU Raptor Research Center.
