Research Interests

I am interested in many aspects of avian biology, especially migration, habitat selection, and the effects of urbanization. I am currently studying the suitability of urban greenspaces as stopover sites for migrating songbirds, as well as the behavior and economic impact of Sandhill Cranes overwintering at Hiwassee Wildlife Refuge, and the breeding biology of Tree Swallows. My graduate students have examined such topics as the impact of exotic vegetation on bird diversity and abundance, nest predation in urban environments, the impact of pedestrian traffic on migrating songbirds, the distribution and population genetics of Northern Saw-whet Owls, and foraging ecology of wintering waterfowl.
