Bald Eagle Migration Update: March 12, 2002
Map and Satellite Data from Our Seven New York Eagles
No sign of more movement yet! Everybody is holding tight, including Eagle E63 who moved up from Delaware on February 20. He's been hanging out in New York ever since.

Ready for Take-off? Tips for Analyzing Spring Migration
March is migration month! When do you predict the eagles will take off? Here are the dates each eagle took off last spring:
| Eagle | Last Spring?s Departure Date |
| E47 | March 14 |
| E49 | March 18 |
| E50 | April 5 |
| E63 | March 7* |
| K58 | March 20 |
| K70 | March 9 |
| K72 | April 2 |
* Notes About Eagle E63
Eagle E63 was captured in New York last March 1. We used March 9 as the date he took off last spring from his capture
site. However, he had probably already been migrating. He had probably flown up from the Chesapeake Bay after wintering
there, just as he did this year. If you go back to inspect last year's map you'll see that he's now in the very
same vicinity in northern New York as he was last year at this time. This eagle's pattern is quite different from
all the others, and shows us how varied migration can be.
Try This!
1) Chose your own eagle, or divide into student groups and chose an eagle for your group. Print out the chart
below, and fill in last spring's departure date for your eagle.
2) As this spring's migration takes place, fill in the facts. Also, go back and see how long the migration took
last year, what path the bird followed, etc. (Sometimes dates are difficult to see on the map, so inspect the
data tables and notice when latitude and longitude changes.)
3) At the end of the migration season, plan to hold a scientific meeting in your class! Use this chart to compare
migration of all of the eagles:
