Maps, Data, and Highlights

The eagles appear to be settled in to their summer grounds. Although they all began the winter around New York State, they have scattered across NE North America: U25 traveled far north into Newfoundland, S28 migrated just over the NY border into ON, U27 is summering in PQ, and U21 is just north of Lake Superior.

Golden eagle R24, arrived at her summer grounds April 6. If all is on schedule for raising a family this season, she is now probably incubating eggs for her new family. Bald eagle U27 arrived at her nest site a week earlier, on March 31. Her eggs may now be ready to hatch!

Special "Thank You" to Eagle Researchers

As the migration season draws to a close, we'd like to turn your attention behind the scenes. Over the past 4 months, in addition to his busy job, Peter Nye found extra time to share his research. More special thanks, to Glenn Hewitt for organizing each week's data for our maps.

Thank you to Christian Martin at New Hampshire Audubon and U.S. Fish and Game for including us on their brand new project to capture and track a bald eagle. Sharing the experience from the scientist's point of view was priceless. Let's wish them luck next winter!


Thank you, Peter!
Thanks, Glenn!
Thank you,Chris!
Journey North would not be possible without the dedication of scientists who contribute their expertise voluntarily!
