Eagle Migration, Map and Data

What is Migration?
Eagle migration does not fit a neat definition. Most eagles do not migrate directly to and from their nests each spring and fall, as people think birds do. As you track Nye's four eagles, you will see why these terms don't fit.

Mapping the Migration
Notice the legend. There are two symbols for each eagle. The small, faded circles show the eagle's path from its breeding grounds. The eagle's path will be shown with the larger, brighter circles as soon as the eagle appears to have stopped moving south and into its winter range. The larger circles will also show the northward path.

Learning from the Maps
Your job is to try to define each eagle's southward migration, the wintering grounds range and its northward migration. We hope you'll enjoy the challenge!

A Migration Highlight

Highlight: U21 on the Move
Bald eagle U21 made an interesting movement this past week. After over 3 weeks in one place she moves toward a new location. Why? What makes the eagles move around in their winter range?

Will the eagle locations change if the region receives the snowfall predicted for this week? How will it affect the eagles? Write your ideas in your Bald Eagle Journal >>

Comparing Fall Migrations: Digging Deeper

Last week we looked at fall migrations. It's hard to believe all 4 of these birds were captured in the same area when you study their different migration patterns!
Sharpen your pencils to collect data from this map, then solve these questions! Which eagle:

  • departed first (leaving breeding ground)
  • arrived first (to wintering ground)
  • took longest time/shortest time
  • traveled the most in one day (average)
