T.J. Zenzal, Ph.D.
TJ Zenzal is a Research Ecologist at the USGS Wetland and Aquatic Research Center.
My research interests include the movement and behavioral ecology of wildlife, particularly birds, with an emphasis on conservation. My research integrates traditional field methods (e.g., bird banding, surveys) with technological advancements (e.g., radio telemetry, weather surveillance radar, isotopes, RFID) to better understand the ecology of avian species as they face severe weather events, habitat/land use change, climate change, and the migratory journey. My dissertation work focused on the stopover ecology of the Ruby-throated Hummingbird in coastal Alabama. My post-doctoral work focused on 1) the integration of weather surveillance radar and traditional field methods to determine how landbirds use stopover habitat as well as react to hurricanes along the Northern Gulf Coast during migration, and 2) the use of wetland habitat created via drainage water management by shorebirds in the mid-West.
