We began this project in 2014 with a grant from the American Eagle Foundation. In 2015, we began collaborating with the US Fish & Wildlife Service, Region 3, Illinois/Iowa Ecological Service Field Office. Our primary method for studying Bald Eagles is telemetry. Since 2014, we have trapped and tagged 30 migrant eagles during winter, 6 eagles at rehabilitation facilities, and 51 nestling eagles.
Bald Eagles are tagged with light-weight GPS telemetry units that will track their movements at intervals as frequent as 4 seconds. The units provide information on location, flight speed, flight altitude and direction, activity rate as measured by an accelerometer, and other diagnostic information. This project is conducted in collaboration with scientists at the US Geological Survey and biologists and engineers at Cellular Tracking Technologies, LLC.
