Maps and Data

We see only short flights and movements for the New York eagles this week. Last week's snowstorm may be responsible for short distance flights, but in general the birds seem to be content where they are.
March isn't far off now. In a typical year we begin to see our winter visitors head back northward then. Keep an eye on their movements and watch for clues that spring is around the corner.

Bald Eagles

(map/data)
  Explore! Getting to Know Our Eagles 
Let's get to know Eagle U25 a little better today. She recently returned from her summer grounds.

Remember, there are two yellow symbols for U25. The small, faded circles show the eagle's path south from her breeding grounds, and the larger, brighter circles show her locations in her winter range.

Visit the map to see where U25 came from and where she is today. Then read today's slide show to find out more.

Travels with a Backpack Satellite Receiver
Last spring and summer, using satellite technology, Peter Nye tracked Eagle U25 over 1000 miles to her nesting site in Canada. Imagine you could fly along with Eagle U25. What do you suppose her habitat in the Canadian wilderness looks like? Join the journey!

Journal Questions: Wondering about Weather

Read through today's slideshow about U25's migration, then answer these questions in your journal:

  • How's the weather today at U25's nest site?
  • When do you predict she'll fly back to her nest? Explain your thinking.
From the Scientists: GMT, Time and Roost
Busy in the Field
Both of our eagle biologists find themselves busy with field work this week. We will catch up on the latest excitement next week.

Meanwhile, this week let's learn more about Satellite information...

Did you know that our eagle biologists look very carefully at the TIME satellite data is transmitted? Let's turn our attention to the “time stamp” that shows up on every data point. Why pay attention to the time?

'Eagle-Eye' Nye writes:
“Night roosts, where the eagles perch at night, 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 today’s handout.

Ask the Eagle Expert

Do you have an eagle question you can't find a good answer for? Each year at this time we accept your questions and submit them to our Eagle Expert, Peter Nye.
You can submit questions February 15 - February 29. We will post the questions and answers March 14.
