Bald Eagle Migration Update: February 19, 2003 Today's Report Includes:
Field Notes from Eagle Eye Nye Hi Kids,
If you had my job, what would you say you've learned so far about eagle behavior?
Have you noticed that one of the eagles isn't in New York? We did capture Eagle E63 in New York, on March 1st, 2001. That spring we tracked his journey north, but we had a very interesting surprise in the fall. He hardly even stopped in New York on his way south. Instead, he went all the way to the Chesapeake Bay! So it seems likely he was a Chesapeake winterer, already on his way back north when we caught him in Spring, 2001. Time will tell what he does this spring. Do you think he'll leave earlier than the New York eagles, since he's further south where it's warmer? His pattern certainly seems unique; I haven't noted any of our wintering birds going down to the Chesapeake Bay area before. Here's something to think about before next week's update: Fish is the bald eagle's favorite food. So what do you suppose eagles eat in the winter time, when rivers and lakes freeze over? Until next time, Eagle Eye Nye You're the Scientist: Challenge Question #4
How hard is this to do? What generalizations can be made? Your job is to define each bald eagle's home range or "winter range." See instructions and definitions here, then try Challenge Question #4:
Human Home Range: Challenge Question #5 To put these eagles' movements into perspective, compare them to your own travels. What is your home range? Describe the area that you occupy in the course of your normal daily activities. Is your winter range different from your summer range? If so, think of the reasons why.
(To respond to these questions, please follow the instructions below.) Discussion of Challenge Question #3 Eagle Facts Found Last week we asked, "If you knew nothing about bald eagles, how many new facts about eagles could you find in Peter Nye's story? Include your list of facts with your answer." Two of our readers, Brett of St. Wendelin High School and M. Lynch, came up with ten facts from a single story! Whenever you read, keep mental notes of the new facts you encounter. Here they are the facts our readers found:
Reading Strategy Spotlight: Identify and Analyze Text Structure Authors make decisions about how to present information to readers. They choose from a variety of structures to organize the information for readers. Reading strategies are specific actions readers take to make meaning from text. Learn how to "Identify and Analyze Text Structure." Then revisit Peter Nye's text describing the capture of Eagle V31. How was the information from Peter Nye organized? Ask the Expert Opens February 21 Does your class have questions for the Expert? Beginning this Friday, your questions will be accepted for Bald Eagle Expert Peter Nye. Submit them any time in the next 2 weeks BEFORE the March 7, 2003 deadline at 1 p.m. (Eastern Time). How to Respond to Today's Challenge Questions:
