Eagle Migration: Map, Data, and Questions
  • This week's migration map >>
  • Data for your own classroom map >>
  • Questions about this week's map (handout) >>
Highlights: This week we wonder how much the cold spring weather is affecting the eagles. U25 and U27 seem to be stopped in their tracks. U21 has a different plan. We just have one new data reading for each bird this week, but you'll see that the data is beginning to tell us a story.
Journal Questions: Predictable or Not?

Predicting the Unpredictable: U21
This far-flying eagle took the route to the west. With just one more signal, three days later, we can see that U21 headed west toward the northern shore of Lake Superior.

Was your prediction correct? Let's take a closer look at the distance she traveled between April 1st and 4th >>
 

Where will she go next? Will she fly the same route as last spring? Look where she started from and where she ended up about a year ago.
