Comparing
Migrations
What generalizations
can you make about eagle migration, based on satellite data? Follow the
trail and the timing of each eagle's migration. To compare multiple years,
print this chart for each year. (Link to Migration
Data Archives.)

Distances traveled by each eagle are measured as the straight line distance
between the nest and the wintering grounds. The actual migration route,
and thus the distance actually traveled, is likely to be longer.
- In addition
to finding the information needed about each eagle for the chart above,
look at the path each eagle took. Was it a direct "bee-line"
to the nest, or did the eagle travel an indirect route and/or move in
stages?
- Describe
any similarities you noticed between all of the eagles.
- Describe
any differences you noticed.
- Describe
any similarities between groups of eagles. (For example, eagles wintering
in the same part of New York, eagles traveling to the same nesting region,
or eagles traveling long or short distances.)
- What questions
were raised by your observations?
- What general
patterns did you observe? What generalizations can you make about Bald
Eagle migration, based on this spring's observations?
