Eagle Migration: Map, Data, and Highlights

Highlights:
It’s officially springtime in the Northern Hemisphere and U21 and U25 have started their northward migration! How does this compare with last year’s migration? Will they continue on the same migration path? This week we will focus on U21 and predict whether she will follow the same route.

Getting to Know You: U21
Let's get to know Eagle U21 a little better today. This week she made a big turn heading north into the middle of NY State. Where was she last year at this time?
Take a look for yourself >>

U21 was captured along the Upper Delaware River on January 15, 2006. This means we have been tracking her for over a year! We know where she went last spring and where she ended up last summer. We also know her fall migration route back to her wintering grounds.

Explore the 2006 Spring Migration map >>

Use your Bald Eagle Journals to describe the 2006 travels of U21. Then take a chance at predicting where she will go this year.

From the Scientist: How Peter Nye Uses Time Stamp Data for Critical Habitat Studies

Did you know that Peter Nye and the NY Department of Environmental Conservation look carefully at the TIME satellite data is transmitted? Have you ever paid much attention to the “time stamp” that shows with every data point?

'Eagle-Eye' Nye writes:
“Night roosts are some of the most critical habitats to wintering bald eagles, especially in severe winter weather.
“We study patterns of regular/annual roost use, so we can pursue protection of those sites if needed.”

Learn how to read the time stamps for each sighting on the eagle map with this lesson. Then try it yourself on using today’s handout.
