Did you know it takes about 35 days to incubate an egg? The eggs are about 2.75 inches long by 2.25 inches wide.

You will be excited to see this week's migration map. A combination of factors seemed to urge the eagles to take flight over the past 10 days. U25 continues to head northward, and seems to win the slow and steady race. How would you describe the flight pace for U21 and U27? Do you wonder if their flight patterns reflect their personalities? There's a lot to record in your journals this week. Imagine taking a ride along with any of the eagles. What would you see? Study and analyze the maps—brought directly to you from satellites—and imagine! |

03/20/09 I live on New Jerseys largest lake and there was a beautiful Bald Eagle soaring and swooping down to the lake yesterday afternoon. It was chased off by first one and then two smaller birds (perhaps osprey) who kept following it and swooping closer and closer. It flew south from my home still over the lake. My wife enjoyed the sighting with me. We are 35+/- miles from the Delaware Water Gap and I know that there are eagles there. Landing, NJ 03/21/09 Eagle has blue band stamped with V34.

U21, U25, and U27 were all captured along the Upper Delaware River in January, 2006. Do the math—how long have we been tracking their migrations? If you take a road trip to visit someone do you often stop at the same places along the way to eat or spend the night? Eagles do this too! Thanks to satellite radios that can operate for multiple years, we have learned a great deal about their 'fidelity,' or faithfulness, to their sites and routes. Will the birds continue to follow the same habits this spring? To help you predict, study the spring migration routes of the eagles. Use your journals to take notes and make your predictions about each bird.

The first egg should have hatched at the Norfolk Botanical Garden eagle nest on around March 13. The other 2 eggs were scheduled to hatch just a day or 2 later. During the daylight hours, if you are lucky, you might see the baby eaglets, or their parents bringing food to them in their nest. Bookmark your class computer to keep an eye on the activity! >> |
