We banded and satellite tagged Bald and Golden Eagles in the upper Chesapeake Bay, USA as part of a program funded in part by the US Army. The Chesapeake Bay is a unique convergence zone for eagles along the Atlantic Coast of North America. It hosts over 1,000 breeding pairs of Bald Eagles year-round, plus thousands of migrant eagles from the southeastern US and northeastern US and Canada. Using the satellite tracking data, we can study the eagles' migration path, roosting patterns, foraging sites, and nesting sites. In addition, we can determine common causes of mortality and provide management recommendations to reduce future eagle mortalities. Eagles were tagged as nestlings or captured as free flying birds. We fitted eagles with backpack harness to hold the solar-powered transmitter in the middle of the eagle's back. Eagles were named after rivers and creeks in the Chesapeake Bay watershed, Canada, and Florida.
