FINAL Migration Update

Journey North News

  • Bald Eagle Migration Update: Feb. 6, 2001
    Eagle Eye Nye is back for the 8th season. You're invited to look over his shoulder this spring as he tracks bald eagle migration by satellite. Read about this season's first surprise. Nye says waterfowl makes up 75% of some NY eagles' winter diet. How can an eagle catch a duck? At Journey North, we hear from scientists studying the migrations of all kinds of creatures. Why do you suppose scientists count manatees, monarchs and eagles in the winter?
  • News Flash: New Bald Eagle Now Online!
    This unschedule report brings exciting news from Eagle Eye Nye: A beautiful female eagle is now online, carrying a satellite backback.
  • Bald Eagle Update: February 20, 2001
    Use today's data to make a "winter range map" for Nye's NY eagles. Your job is to define each bald eagle's wintering range, and then describe the eagle's behavior within that range. To put these eagles' travels in perspective, make a human home range map and compare the eagle's travels to your own. How does an eagle catch a fast-flying duck? Read first-hand observations about eagle hunting techniques then tell us why eagles talons are better than beaks for carrying food.
  • Bald Eagle Migration Update: March 6, 2001
    March is migration month! If last year's data are any clue, the first eagle should take off any moment. How large is an eagle's home range, and how does it compare to yours? Eagles are famous for their vision. How do you think scientists evaluate how good an eagle's eyes really are?
  • Bald Eagle Migration Update: March 13, 2001
    They're off! After last week's blizzard, the first two eagles have headed north---and Nye's team captured another bird for spring tracking. "A two day snowstorm means that eagles are stuck in their roosts and unable to hunt. So when the storm clears they come out hungry, looking for food and willing to take chances they might normally avoid."
  • Bald Eagle Migration Update: March 20, 2001
    Five of our nine eagles are now on their way! One has already arrived in her nesting territory! How long did eagle F43's migration take? Guess the location of each eagle's nest along with Biologist Nye. Watch North America's snow and ice melt on this animated loop--how does the timing of eagle migration relate to the melting of ice and snow? Finally, through comparative anatomy, learn how eagle eyes are different from our own.
  • Bald Eagle Migration Update: March 27, 2001
    "They're moving out!" says Peter Nye. "Only Eagle E50 remains here in New York now." How fast and far do eagles travel in a day? Answer this question using data from Eagle K58, who felt like flying on the first day of spring. Also, get ready to track Nye's first golden eagle by satellite-telemetry!
  • News Flash: Golden Eagle Free to Fly!
    Rescued from lead poisoning and released in New York on March 29th, Golden Eagle's migration will be tracked by satellite.
  • Bald Eagle Migration Update: April 3, 2001
    All of the Bald Eagles are now underway, except for Eagle E50--even though it's April! When do you suppose he'll finally take off? How far did E47 fly over the weekend? And why did E63 turn around and head south? As for the big question--where are these birds headed? Biologist Nye guesses the location of their nests.
  • Bald Eagle Migration Update: April 10, 2001
    "Well, well, guess who finally decided to move!" exclaimed Peter Nye. Let's keep an eye on Eagle E50! Eagles that leave late are expected to go a long, long way north. Before satellite telemetry, nobody knew how far eagles traveled during a typical day of migration. Let's see what this season's data show. After Golden Eagle #004's release, students asked about lead poisoning. Learn what a bird rehabilitator has learned about lead, and how you can get a free lead sinker for fishing!
  • Bald Eagle Migration Update: April 17, 2001
    Nye's eagles all spent the winter as neighbors in New York but are now spread across northern Canada. Check out how far apart their travels have taken them. Do you think male or female eagles arrive back at their nest site first? Today's report includes a primer about bird flight. Birds have many adaptations to make them light for flight--Have you ever wondered about the effect the satellite transmitters might have on the eagles?
  • Bald Eagle Migration Update: April 24, 2001
    Look who's in Labrador! Eagle E50 waited until April to take off, but look at him now--he flew 656 miles in a single week and now he's in Labrador! Take a close look at today's migration map. Do you think all of the eagle have reached their nests yet? This time of year, we're so busy tracking eagles to their nests, that we often forget about the many birds who are too young to nest but aren't babies anymore. Why might the migration of a juvenile eagle be different from the migration of an adult eagle?
  • Bald Eagle Migration Update: May 1, 2001
    Now that the migration season is coming to a close, what do you suppose is happening on the nesting grounds of the eagles you've tracked this spring? Peter Nye describes eagle nests--his visits, the view, and also the smell! Visit an eagle nest by remote, and take your own field notes. Then compare the duties of male and female eagles during the nesting season.
  • FINAL Bald Eagle Migration Update: May 15, 2001
    As we close this spring, all our Bald Eagles appear to be settling back on their summer breeding grounds. What generalizations can you make about Bald Eagle migration, based on this spring's observations? Go back and follow the trail and the timing of each eagle's migration. Then write your own scientific paper or have a scientific meeting in your classroom, based on the Bald Eagle research you have witnessed.
