Eastern Bald Eagle Migration Update: March 10, 1999
Today's Report Includes:
Field Notes From Biologist Peter Nye
Eagles Apparently Changed Their Minds--Why?
Challenge Question # 8
As you'll see when you map today's satellite data, on 7 March Eagle #F43 moved back onto the Hudson from her wanderings of early March up near MA and over in CT. At about the same time (8 March), Eagle #F81 moved back south from his previous locations up in northern NH--all the way to a location near where he was wintering. This guy is back now on the NY/VT border! A couple of interesting movements there.

Discussion of Challenge Question #6
Last week we asked, "As the crow flies, what's the total distance between all the places where the satellite received readings from Eagle #F83? Explain why the EAGLE actually may have flown further."
Jayson & Jay of Scott Young Public School got it : "Eagle #83 has traveled 140.08 miles and 224.2 km in total. He could have flown farther because his collar was only activated four times in seven days."
So true! Satellite data gives us only a snapshot of eagle behavior. This
is something biologists must always keep in mind when analyzing their data, being careful not to make assumptions.
