Latest News and Migration Map
Field Notes from Peter Nye Hello All, A20 continues to move north also, while A00 is content where he is. Regards, until next week. Eagleye Reading Between the Data Points Pete Nye thinks that our new Bald eagle V98 is “on her way.” How does he come to this conclusion? A glance at the data doesn’t show much change. Our mapmaker, Daphne was also curious about Eagleye’s observation, “I labeled two of the new data points individually instead of in that clump in case that little bit of movement means something!” What do you think? Here are the dates and the locations:
Study the data giving particular attention to the 3 signals recorded on 4/05 (a windy day).
(To respond to this question, please follow the instructions below.) Comparisons Between Golden and Bald Eagles Bald Eagles belong to a group called "fishing eagles." Golden Eagles are not closely related to Bald Eagles, they are more closely related to hawks called "buteos," a group which includes the Red-tailed Hawk. But Golden Eagles look a lot like immature Bald Eagles, from their huge size and 80-inch wingspan to their dark plumage. Golden Eagles have feet adapted to catching their prey on the ground. Their legs are well-feathered, unlike the legs of Bald Eagles.

When Will They Hatch? Discussion of CQ #20 Eagles Online has a Web camera poised over a Bald eagle nest in MA. The nest contains 2 eggs laid on March 8, and 11. We asked you, “When do you predict each of the eggs in the Eagles Online Webcam nest will hatch?” Fifth Grader, Monique from Ferrisburgh Central School predicted the eggs will hatch around April 14. That’s TODAY! Thanks also to Seventh Graders at Iselin Middle School for their prediction - ! How do YOU figure the dates? Here is one way:
Keep an eye on the Webcam and maybe you can witness this historic event in the life cycle of one of our most magnificent North American birds! How Much do Satellite Transmitters Weigh? Discussion CQ #21 “If you wore a backpack that weighed 2% of your body weight, how heavy would your backpack be?” Three third
graders from Ferrisburgh Central School weigh between 50 and 90 pounds.
Here is what they calculated: Their backpack would weigh between 1 and
1.8 pounds.
Ashley, Charlie and Kristian all think that the eagles get used to the weight and don't notice it at all. Seventh Graders weigh more. At Iselin Middle School, Danielle, Robert M, Chris C, Moaz, Tom, Heather, Kristina and Caitlin weighed in for this problem. Ranging in weight from 79 to 125 lbs, their backpacks would need to weigh between 1.58 and 2.5 lbs. How to Respond to Today's Challenge Questions:
